Front matter

Preface

A building is a promise. The people who walk into a classroom, a clinic waiting room or a plant floor trust that the roof will hold, the exits will open, the alarm will sound and the air is fit to breathe. Someone keeps that promise every day, usually without being noticed, and usually with less money than the building needs.

That someone is the facility manager, supported by inspectors, engineers, code officials, custodians, technicians and contractors. Their work sits where engineering, law, finance and plain human attention meet. Most of them were never taught the whole picture. They learned a trade, then inherited a portfolio.

This handbook tries to give them the whole picture. It teaches how buildings work, how they fail, how to look at them without hurting yourself or overstepping your qualifications, how to write down what you find so that someone can act on it, and how to work out which laws, codes and standards actually apply. It is written for beginners but does not shy from the detail that experienced professionals need.

Two commitments shape every page. First, accuracy over coverage. Where a requirement could not be verified, the book says so and sends you to the authority that decides. Second, honest boundaries. A visual walk-through is not a substitute for specialized testing or professional engineering, and a textbook is not a license.

Who this is for

Facility teams

Facility managers, maintenance supervisors, operations directors and technicians in school districts, universities, hospitals, offices, housing and industry.

Owners and boards

School boards, property owners, association boards and executives who approve budgets and need to read a condition report with confidence.

Inspectors and code staff

Building, fire and housing inspectors, and consultants who want a consistent method and a shared vocabulary with the people they inspect.

Contractors and engineers

Design and construction professionals who hand over buildings and want to know how owners will operate and maintain them.

Students and trainees

College and continuing-education learners in facilities, construction and building-science programs. Every chapter ends with exercises and a quiz.

Public agencies

Government facility groups, housing authorities and safety officers who work within procurement, funding and public-accountability rules.

Scope and limitations

This edition covers the foundations of facility management, the major building systems, the professional inspection process, and life safety, accessibility and environmental health. School buildings are the main worked setting, and the principles carry to other occupancies. It explains common principles first, then what changes by occupancy, building type, jurisdiction and risk level. Commercial, residential and industrial facilities, budgeting and capital projects, and facility technology are outside the scope of this edition.

Read before relying on any requirement
  • This book supports professional learning. It does not establish legal compliance, confer a license, replace a required inspection or override the authority having jurisdiction (AHJ).
  • Model codes and consensus standards are law only where a government has adopted them. Edition and local amendments decide the actual requirement.
  • Louisiana and New Orleans are the worked example. Nothing about New Orleans is assumed to apply across Louisiana, and no edition is assumed to be in force without a source check. Dates of checks are shown.
  • No chapter contains real inspection results, code approvals or agency endorsements. Photographs are not used. Drawings are conceptual and labeled. Case studies and data are fictional.
  • The book has not won an award and has no endorsement from any government agency or standards body.
Safety boundary

Nothing here instructs an unqualified reader to enter a confined space, open energized equipment, disturb suspected asbestos, collect hazardous samples, bypass a machine guard, disable a fire system or perform any hazardous work beyond their training. Where a task requires a licensed contractor, professional engineer, certified inspector or industrial hygienist, the text says so.

How to read the signs

Callouts use label bands, like safety signage. The colors are a teaching convention in this book. They are not a claim of conformity with any signage standard.

Danger
A hazard that can seriously injure or kill. Includes stop-work conditions.
Warning
A hazard or error that can cause harm or a violation if mishandled.
Caution
A lesser hazard or common trap.
Field note
A practical technique used by experienced inspectors.
Verify
A requirement that depends on jurisdiction, edition or facts you must confirm with the AHJ.
Fictional
Invented data or a made-up facility used for teaching only.

Book architecture

Four parts, twenty chapters, then back matter. Every chapter follows the same eighteen-part format so readers always know where to find the legal context, the inspection demonstration, the sample findings and the field checklist.

Regulatory research and verification framework

Who decides what you must do

Most compliance mistakes come from treating every document with a code number as law. Start by sorting what you are reading into one of eight layers. Then check whether that layer binds your building.

Figure 0.1Eight layers of authority
1
Federal law and regulationStatutes and agency rules
OSH Act; AHERA rule (40 CFR 763 Subpart E); ADA; Fair Housing Act; EPA rulesBinding
2
State statute and regulationLegislature and state agencies

3
Local ordinanceCity, parish or county
Permit rules, local amendments, zoning, historic-district rulesBinding
4

IBC, IFC, IMC, IPC, IPMC, NEC, NFPA 101 where adopted. Edition and amendments control.Binding if adopted
5
Contract and funding conditionsGrants, bonds, leases, insurance
Grant terms, procurement documents, loan covenants, lease dutiesBinding by agreement
6
Consensus standard not adoptedWritten by a standards body
ASHRAE, ASTM, NFPA documents not adopted locallyVoluntary unless referenced
7
Agency guidanceExplains, advises, interprets
EPA school air and water guidance, agency fact sheets and webinarsNot binding itself
8
Best practice and district policyProfessional practice, board policy
Board maintenance policies, internal response times, manufacturer adviceBinding only as policy
Layers one to five can create legal duties. Layers six to eight cannot unless a layer above incorporates them. A guidance document can still describe the best way to meet a binding rule, which is why it matters.What to learn Before you cite a document, name its layer. Then answer: who adopted it, which edition, and does it apply to this building and this work?

Eight-step verification protocol

  1. Name the authority. Which agency issues or enforces it?
  2. Find the primary source. Statute, regulation, ordinance or the standards body itself.
  3. Confirm edition and adoption date. Do not assume the latest edition is in force.
  4. Read the amendments. State and local changes can reverse a model-code rule.
  1. Test scope and exceptions. Construction date, occupancy, type of work, funding source and building class often decide applicability.
  2. Record the date checked and the link, so a reader knows how fresh it is.
  3. Classify the layer from Figure 0.1.
  4. If unverified, say so and send the reader to the AHJ. Never invent a section number.

Source register

Checked October 2026. “Verified” means the author read the current text or official page for this edition. Jurisdiction-specific items marked “Not verified” in a chapter table must be confirmed locally.

AreaSourcePublisherWhat was foundStatus

Worked example: Louisiana and New Orleans

What the sources say

  • Louisiana has a state construction code body (the site now calls it the Louisiana Uniform Construction Code commission; the earlier name was the State Uniform Construction Code Council). Its site lists the 2021 ICC codes with Louisiana amendments.
  • A rule to adopt the 2023 National Electrical Code and the 2024 International Codes was proposed in the August 20, 2026 Louisiana Register. No effective date is stated.
  • The State Fire Marshal is a separate authority and adopts codes by reference through LAC 55:V.103.
  • New Orleans enforces the international codes and the NEC with local amendments through the Department of Safety and Permits.

What it teaches

  • Several authorities, one building. A school can answer to the state commission, the State Fire Marshal, the local building official and federal agencies at once.
  • Editions move. A pending rule is not a rule in force. Check effective dates before changing a specification.
  • Local pages go stale. The City page names no editions and was last updated in 2022.
  • Do not generalize. What applies in Orleans Parish may not apply in another parish.
Note
The Louisiana citations and the NFPA 101 edition in this register were checked against LAC 55:V.103 and the Office of State Fire Marshal in October 2026. Editions change, so confirm the edition in force on the date of any inspection or decision.

Part I · Foundations of Facility Management

The Facility Manager’s Role and Responsibilities

What does a facility manager actually own, and how do you start when you inherit a portfolio?

Chapter 1 of 20

1.1Opening scenario#

Fictional scenario · Pelican Parish Schools is invented

Dana Whitfield started on Monday. By 6:40 Tuesday morning she had three voicemails about Bayou Crossing Elementary, a 1971 building that was one of fourteen in her new portfolio.

The first was from a teacher. A brown stain had spread across the ceiling of Room 114 over the weekend, and the room smelled damp. The second was from a custodian. The fire-alarm panel by the front office had been beeping for more than a week, so someone had silenced it. The third was from a data-cable contractor, polite and in a hurry, who wanted to cut channels into a plaster wall in the east wing that afternoon.

Three messages, three building systems, three different kinds of risk. Dana had no history with the building, no budget to fix everything and no one to hand the problems to. What she did next would show whether she was managing the facilities or only answering the phone.

This chapter teaches how to think through a morning like that: what you own, what the law expects, what to do first and who to call. Dana’s three problems return throughout the chapter.

1.2Learning objectives#

After this chapter you should be able to:

  1. Define facility management and distinguish it from property management and construction project management.
  2. List the major responsibility areas of a facility manager and the systems they touch.
  3. Explain the difference between a law, an adopted code, a consensus standard, guidance and district policy.
  4. Decide, for a stated building and task, which requirement layers to check.
  5. Run a first-30-days baseline walk and document what you find in a consistent format.
  6. Rank problems by risk and apply the life-safety override.

1.3Why the subject matters#

Four reasons make the role important beyond keeping the lights on.

  • People. Buildings hold children, patients, residents and workers. Failures of exits, alarms, air and structure fall on them first.
  • Law. Owners and employers carry legal duties. Missed inspections, undocumented repairs and ignored notices become the evidence in a dispute.
  • Money. Deferred maintenance compounds. A small roof repair left alone becomes wet insulation, damaged finishes and a possible mold response. Spending early is usually cheaper, though only a condition assessment can tell you for a given building.
  • Mission. A school cannot teach in a flooded wing, and a plant cannot ship from a locked-out line. Facility work protects the work the building exists to support.

1.4Plain-English technical explanation#

Facility management is the coordinated care of buildings, grounds and their systems so the people inside can do their work safely and the owner’s investment lasts. A useful analogy is a ship’s chief engineer: the vessel is built by someone else, but the chief engineer keeps it running, safe and seaworthy every day until it is retired.

The title overlaps with two others. The table separates them by the question each role asks every day.

RoleDaily questionTime horizonTypical outputsSuccess looks like
Facility managerIs the building safe, working and ready for the people using it?Decades of operationInspection programs, work orders, budgets, condition reports, compliance recordsFew surprises, fewer emergencies, assets lasting as planned, clean audit trail
Property managerIs the property earning, leased and keeping tenants satisfied?Lease terms and fiscal yearsRent rolls, tenant communications, vendor contracts, operating statementsOccupancy, collections and net operating income
Construction project managerWill this defined project finish on time, on budget and to specification?Weeks to years, then it endsSchedules, cost reports, change orders, inspections, closeout packageDelivered scope, accepted work, complete handover

In practice they overlap. A school facility manager often acts as owner’s representative on a renovation, and a property manager schedules repairs. The roles differ in what they are accountable for.

People

Occupants, staff, contractors, inspectors, regulators and board members. You communicate risk to all of them.

Place

Buildings, grounds and systems: structure, envelope, mechanical, electrical, plumbing, fire protection, vertical transportation and site.

Process

Inspections, preventive maintenance, work orders, procurement, emergency response and records.

1.5Applicable laws, codes, standards and official references#

A facility manager works under many layers at once. This table lists the ones that shape the role itself. Later chapters take each in depth.

RequirementLayerWhat it means for the facility managerVerification note

Warning
A written school or company policy can be stricter than the law. If your own policy says you will do something, an auditor or plaintiff will hold you to it. Write policies you can actually carry out.

1.6How to decide whether a requirement applies#

Ask six questions, in order, before you tell anyone something is required.

  1. Who owns and operates the building? Public entity, private non-profit or private for-profit.
  2. What is it used for? Occupancy and activity decide the fire, egress and accessibility rules.
  3. When was it built or last altered? Construction date triggers exemptions and lead-paint rules; alteration triggers current-code duties for the altered area.
  4. What work is happening? Routine maintenance, alteration, demolition and new construction fall under different rules.
  5. What hazards are present? Asbestos, lead, chemicals, hazardous energy, refrigerants, water systems.
  6. Who is paying? Grants, bonds and insurance add contract conditions.

Then use Tool R-1, the Requirement Finder, to list which layers to check, and finish with the eight-step protocol in the framework above.

Verify
The question answers tell you where to look. They do not tell you the final answer. Confirm with the AHJ, counsel or a qualified specialist before acting on a legal conclusion.

1.7Building systems, components and terminology#

Ten system families recur through the book. You do not need to be an expert in each, but you must know what they are, who services them and when to call a specialist.

Key terms for this chapter, with fuller definitions in the glossary:

AHJ

The agency with legal power to approve, inspect or enforce.

Impairment

A fire protection system that is out of service or reduced. It triggers notifications and interim safety measures.

Qualified person

Someone with training and demonstrated ability for a task, as the relevant rule defines.

Deferred maintenance

Needed work that has been postponed, usually for lack of funds.

CMMS

Software that issues, tracks and reports work orders and schedules.

FCI

Facility Condition Index: deferred maintenance divided by current replacement value.

1.8Step-by-step inspection demonstration#

Fictional facility
Bayou Crossing Elementary, Pelican Parish Schools. Dana’s baseline walk happens on Tuesday, October 20 (fictional). Each demonstration answers the same eleven questions.

A baseline walk is the first pass through a building you do not know. Its goal is not to fix things. It is to find what could hurt people today, learn what records exist and decide what to do first. Do the walk with a second person, a flashlight, a camera or phone, a notebook or tablet, and a copy of the floor plan.

Demonstration A: The ceiling stain in Room 114
Looking for
Source of water, size and age of the stain, active dripping, sagging tile, visible growth, damp smell.
Why it matters
Water leaks damage finishes and insulation and can support mold growth. A sagging ceiling can also fall.
Documents to review
Roof inspection and repair history, work-order history for the room, roof warranty, drawings of the roof drains above.
Check visually
Stain edges and rings, drip locations, tile sag, damp insulation above a lifted tile (with a stable ladder and two people), signs of condensation on pipes, exterior roof area above from a safe vantage point.
Instruments or specialists
Moisture meter for surfaces; infrared or electronic moisture survey by a roofing or building-envelope specialist; an industrial hygienist if growth or extensive wetting is found.
Potential deficiency
Active roof or plumbing leak, water-damaged ceiling, possible moisture-related growth.
Location and evidence
Room number, grid location (for example, column line C-4), photographs with a scale reference, moisture-meter readings with time, sketch on the floor plan.
Immediate risk
Falling ceiling material and slips are the immediate risks. Cordon the area. Mold risk is evaluated, not assumed.
Who is notified
Principal and teacher, roofing or plumbing contractor, and an industrial hygienist if the extent or growth warrants it.
Prioritize and verify
High, until the source is stopped. Verify by re-inspecting after the next rain and re-reading moisture levels after drying.
Records to keep
Photos, readings, work orders, contractor reports, drying log and re-inspection results.
Demonstration B: The silenced fire-alarm trouble signal
Looking for
The panel display: which trouble condition, how long, who silenced it and what was done.
Why it matters
A trouble condition can mean part of the alarm system will not work in a fire. Silencing the buzzer hides the problem without fixing it.
Documents to review
Panel event history, inspection and testing reports, last service report, impairment log, fire-code requirements as adopted.
Check visually
Panel indicators and message. Do not reset or silence further.
Instruments or specialists
Diagnosis and repair by a licensed fire alarm contractor. Testing follows the adopted fire-alarm standard.
Potential deficiency
Fire-alarm system impairment; missing impairment notification and interim measures.
Location and evidence
Panel location, photo of the display, event log printout, time of discovery.
Immediate risk
High consequence. Treat as critical under the life-safety override until the contractor says the system is working or interim measures are in place.
Who is notified
Principal and superintendent immediately, the alarm contractor, and the fire authority if your adopted code or monitoring contract requires it.
Prioritize and verify
Critical, same day. Verify with a contractor service report and a documented functional test.
Records to keep
Event history, impairment notices, interim-measure log, contractor report, test results.
Demonstration C: The request to cut into a plaster wall
Looking for
Whether the wall is known or suspected to contain asbestos, and what the work would disturb.
Why it matters
Disturbing asbestos-containing material can release fibers. For schools, federal rules require management plans, accredited personnel and specific procedures.
Documents to review
The district’s AHERA management plan, inspection reports and sample results for the building, and the planned scope of cabling work.
Check visually
Wall condition and location relative to mapped homogeneous areas in the plan. Do not touch, sand or sample.
Instruments or specialists
Sampling, assessment and any response action by accredited asbestos professionals. Air monitoring as required.
Potential deficiency
Proposed disturbance of suspect or assumed asbestos-containing material without plan review or notification.
Location and evidence
Wall identifier, copy of the plan page, photo of the wall, contractor’s request in writing.
Immediate risk
Exposure risk if the work starts. Stop-work until verified.
Who is notified
The district’s designated AHERA person, the contractor, and an accredited professional.
Prioritize and verify
High with stop-work. Verify by written clearance, updated plan and documented notification.
Records to keep
Plan excerpts, clearance letter, contractor correspondence, notification copy.
Stop-work conditions
Stop and escalate if you see exposed wiring or live equipment, a suspected hazardous material, an unstable ceiling or roof, a blocked or locked exit, or a closed fire-protection valve. Do not attempt to repair, sample, reset or bypass. Make the area safe, keep people away and call the right specialist.

1.9Annotated visual#

Figure 1.1Building anatomy and the nine systems you inspect first
Conceptual drawing of a generic two-story building, not drawn to scale and not a real facility. The second-floor sprinkler system is omitted for clarity. What to learn Every system has a physical path from the street or roof into the building. When something fails indoors, trace the path: water from roof and site, power from the pad transformer, air from the roof unit, escape routes to the exit door.

1.10Common defects and their warning signs#

At the program level, trouble announces itself in the records and routines long before a building fails. Learn these signs.

Warning signWhat it usually meansFirst response
The same work order is reopened again and againSymptom is being treated; root cause is untouchedInvestigate the cause; involve a specialist; close only on verification
Inspection tags are missing or out of dateRequired inspections and testing are being missedPull records; schedule overdue work; notify the responsible officer
Alarm or sprinkler trouble signals are silencedImpairment culture; no one owns the responseTreat as critical; confirm impairment procedures and contractors
Contractors request to cut, drill or core in older buildings without records reviewNo gatekeeper for work that can disturb hazardous materialsCreate a pre-work review step tied to the asbestos plan
Staff can’t find the asbestos plan, drawings or warrantiesRecords are scattered, not managedCreate a records index; assign an owner; set review dates
Most work is emergency repairPreventive maintenance is underfunded or not scheduledStart a preventive program for life-safety and high-failure systems
Budget requests are rejected without numbers behind themNo asset register or condition dataBuild a register and condition baseline (Chapter 3)

1.11Realistic case study: The Quiet Panel#

Fictional case
Magnolia Heights Middle School and all people in it are invented. The case is a composite of patterns, not a record of a real event.

What happened. A trouble signal began at the fire-alarm panel in a 1980s middle school. The panel buzzed during classes, so the front-office assistant silenced it. Each morning it buzzed again and was silenced again. A work order was created but never assigned because it was marked “non-urgent, no smoke.” Three weeks later, a contractor working in the ceiling above the cafeteria bumped a detector wire. At the next monthly drill, several horns in the east wing did not sound. The drill was ended and the district called the alarm contractor. The contractor found two separate faults: the original ground fault, and the damaged circuit from the later work.

What went wrong.

  • No one owned the response to a trouble signal. It was treated as noise.
  • The work order had no risk classification, so a life-safety item sat in the same queue as paint touch-ups.
  • No impairment procedure: no interim measures, no notifications, no log.
  • Contractor work above ceilings was not coordinated with the alarm system.

Model answer. A well-run program classifies a trouble signal as critical on day one. The front office has a one-page response: do not silence repeatedly, call the facility manager, who confirms the condition, calls the alarm contractor and, per the adopted fire code and the district’s impairment procedure, notifies the required parties and arranges interim measures. A work order carries a risk field. Contractors are briefed on life-safety systems before ceiling work. The drill found the second fault, but the first could have been fixed three weeks earlier.

Instructor discussion prompts
  1. Which single change would have prevented the most harm?
  2. Who should own the first call when a trouble signal appears at 7:30 a.m.?
  3. How should a work-order system distinguish life-safety items?
  4. What should the contractor-orientation checklist include?

1.12Sample inspection findings and documentation#

1.13Risk classification and corrective actions#

Risk ranking turns a long list into an order of action. Multiply likelihood (how likely harm is) by consequence (how bad it would be). Then apply the life-safety override: any condition that could prevent occupants from escaping or being warned, or that exposes people to a serious hazard now, is Critical regardless of score.

Tool 1.1Risk matrix with Dana’s three problems

Tap any cell. Markers show Dana’s items: A ceiling stain, B silenced alarm, C wall cut. Rows: likelihood 5 (almost certain) to 1 (rare). Columns: consequence 1 (minor) to 5 (catastrophic). Illustrative bands; adopt your own policy.

Select a cell.
TierScoreTypical responseIllustrative target
Critical20 to 25, or any life-safety overrideMake safe now. Remove people from the hazard or put interim measures in place. Escalate the same day.Same day
High10 to 16Assign owner and contractor, protect people, schedule repair soon.Within days
Medium5 to 9Plan and fund within the work program.Within weeks to a few months
Low1 to 4Monitor or fold into routine maintenance.Planned cycle
Caution
These bands and target times are teaching examples. Your policy, your AHJ and the specific requirement set the real deadlines. A matrix helps judgment. It does not replace it.

Corrective-action planning. Each finding needs an owner, a date, a method of verification and a closure record. “Fixed” is not closure. Closure is a record showing who verified the fix and how.

1.14Common mistakes and professional lessons#

  • Treating a model code as law. It is law only if adopted, in the edition adopted, with local amendments.
  • Fixing the symptom. Painting a stain or silencing an alarm hides the cause.
  • Letting the loudest complaint win. Rank by risk, then explain the order to complainants.
  • Going beyond your qualifications. Opening panels, sampling suspect material or climbing onto a roof alone are classic ways to get hurt.
  • Not writing it down. Undocumented work cannot be shown to an auditor or defended later.
  • Promising what you cannot do. Policies stricter than your capacity become liabilities.
  • Skipping contractor orientation. Contractors damage life-safety systems and disturb hazardous materials when no one tells them what is above the ceiling.

    Remember
    • The facility manager owns the long life of the building. The property manager owns the income. The construction project manager owns a bounded project.
    • Sort every document by layer of authority before treating it as a requirement.
    • Rank by risk, and apply the life-safety override first.
    • Know where your qualifications end and escalate in time.
    • Write it down, assign an owner, verify closure.
    • Verify editions and adoption with the AHJ. Dates matter.

    Ownership, Operations, Maintenance and Lifecycle

    Why do buildings that look fine fail suddenly, and what does it take to keep that from happening?

    Chapter 2 of 20

    2.1Opening scenario#

    Fictional scenario · Cypress Middle School is invented

    On the Tuesday before school opened in August, Dana Whitfield stood on the roof of Cypress Middle with a technician and watched a rooftop air conditioner shudder to a stop. Inside, the gym was already 86 degrees and the first teacher in-service was Thursday.

    The technician replaced the drive belt for the third time since March. “It keeps eating belts,” he said. He had never been told why. The filter rack was packed with dust, a condensate line was half blocked, and the logbook taped inside the panel door ended in April.

    Back in the office, the work-order system showed forty-one calls for that single unit in two years, almost all marked “complete.” Not one was a scheduled visit. Dana realized the building had never been maintained. It had only been repaired.

    This chapter explains the difference, and how to move a portfolio from the first to the second without a bigger budget.

    2.2Learning objectives#

    1. Describe the phases of a building’s life and who owns the decisions in each.
    2. Distinguish preventive, predictive, corrective and reactive maintenance, and say when each makes sense.
    3. Explain why some maintenance is a legal or contractual duty and not a choice.
    4. Compare maintenance strategies using a simple expected-cost model.
    5. Audit a preventive-maintenance program using records and a short walk.
    6. Choose a strategy for an asset from its criticality and failure behavior.

    2.3Why the subject matters#

    • Failures cluster at the worst time. Heating fails in the cold snap and cooling fails in the heat wave, because that is when systems work hardest.
    • Emergencies cost more than plans. Rush labor, expedited parts and rental equipment usually cost more than the same work scheduled. How much more depends on the asset and the market, which is why you measure your own.
    • Some maintenance is required. Fire protection, pressure vessels, elevators and backflow devices often carry inspection duties set by law, adopted codes or insurers.
    • Warranties and insurance can depend on it. Many equipment warranties require documented service. Missing records can void them.
    • Lifecycle decisions are hard to reverse. Choices made at design and purchase set what the building will cost to operate for decades.

    2.4Plain-English technical explanation#

    The building lifecycle

    A building passes through phases, and the facility manager is involved in all of them even though most of the calendar is spent in one.

    PhaseWhat happensWho mainly decidesThe facility manager’s job
    Plan and designNeeds, site, budget, systems and materials chosenOwner, architect, engineersSpeak for operations: access, durability, standard equipment, spare parts, training
    ConstructBuilding is built and inspectedContractor, owner’s project manager, AHJWatch for installation issues; collect submittals and warranties
    Commission and hand overSystems tested; staff trained; records transferredCommissioning agent, ownerReceive and verify drawings, manuals, test reports, training
    Operate and maintainDaily use, inspections, preventive work, repairsFacility manager and occupantsRun the maintenance program; keep records; control cost
    Renew and adaptSystems replaced; spaces alteredOwner, board, designersPlan capital renewal; manage disruption; apply current-code duties to altered areas
    Dispose or repurposeBuilding sold, reused or demolishedOwner, regulatorsHazardous-material surveys; closure records

    Four maintenance strategies

    StrategyTriggerExampleBest used whenMain risk
    PreventiveCalendar or run hoursQuarterly belt, filter and coil service on a rooftop unitWear is age- or use-related; a failure is costly; service is cheapOver-servicing; doing work that is not needed; ignoring actual condition
    Predictive (condition-based)A measurement crosses a limitRising vibration on a pump bearing; oil analysis on a generatorA reliable warning appears before failure and can be measuredNeeds instruments, skill and discipline to act on the readings
    CorrectiveA fault is foundRepairing a dripping valve found on rounds, scheduled for next weekThe problem is not urgent but should be fixedBacklog grows if corrective work is never scheduled
    Reactive (run to failure)FailureReplacing a burned-out lamp in a storage roomFailure is cheap, safe and easy to fix, and spares are on handUsed by default on assets where failure is dangerous or expensive
    Field note
    Reactive maintenance is not wrong. Running a hundred hallway lamps to failure is rational. The error is reactive maintenance by neglect, on an asset where failure matters.

    A common planning framework is reliability-centered maintenance: for each asset, ask what its function is, how it can fail, what happens when it does, and which task, if any, is worth doing. The tools in this chapter apply that thinking at a beginner level.

    2.5Applicable laws, codes, standards and official references#

    Most maintenance is a management choice. The items below are the exceptions: places where law, adopted code, contract or insurance make it mandatory.

    RequirementLayerEffect on maintenanceVerification note
    OSHA portable fire extinguishers, 29 CFR 1910.157(e)Federal lawThe employer must inspect, maintain and test extinguishers.

    Verify
    Intervals quoted from memory or from vendor blogs are a common source of compliance mistakes. Read the adopted edition, then write the interval into your schedule with the source and date.

    2.6How to decide whether a requirement applies#

    For any asset, work down this list. The first yes that carries a legal or contractual duty sets a floor you cannot go below.

    1. Is it a life-safety system? Alarms, sprinklers, extinguishers, emergency lighting, exit hardware. Expect adopted inspection and testing rules.
    2. Is it covered by a state inspection program? Boilers, pressure vessels, elevators, amusement or pool equipment.
    3. Does it contain regulated substances? Refrigerants, fuel, chemicals.
    4. Is there a warranty or service contract with conditions?
    5. Does your insurer or lender impose conditions?
    6. Only then choose a strategy by criticality and failure behavior (Tool 2.2).

    2.7Building systems, components and terminology#

    Useful life

    How long an asset is expected to serve before replacement makes more sense than repair.

    Remaining useful life

    Useful life minus age, adjusted for condition. An old asset in good condition can outlive its table value.

    Critical asset

    One whose failure would endanger people, stop the mission or cost a great deal.

    Run hours

    Hours of operation, used instead of the calendar for equipment that runs unevenly.

    Backlog

    Approved or identified work not yet done. Corrective work and deferred maintenance pile up here.

    Root cause

    The underlying reason for a failure, not the part that broke.

    Illustrative service lives help with planning. They are broad ranges, not promises. Use manufacturer data and your own history where you have it.

    AssetIllustrative range (years)What shortens it
    Rooftop air-conditioning unit15 to 20Coastal salt air, dirty coils, missed service, heavy run hours
    Low-slope membrane roof20 to 30 (varies widely by type)Ponding water, foot traffic, poor flashing, no drainage cleaning
    Boiler25 to 35Poor water treatment, short cycling
    Chiller20 to 30Fouled tubes, loss of refrigerant, poor controls
    Fire alarm control panel15 to 25 (parts support often ends sooner)Obsolescence, battery neglect
    Illustrative
    These ranges are broad teaching values. They are not from a single authoritative table and should not be used for a capital plan. Chapter 3 shows how to build one from evidence.

    2.8Step-by-step inspection demonstration#

    Fictional facility
    Cypress Middle School, Pelican Parish Schools. Dana audits the preventive-maintenance program in the second week. An audit examines records first, then confirms them on a short walk.
    Demonstration A: The rooftop unit that eats belts
    Looking for
    Whether the unit has a scheduled service plan, what was done, and why belts keep failing.
    Why it matters
    Repeated belt failure points to a cause: misalignment, wrong tension, bad pulleys, a seizing bearing or overload from dirty coils.
    Documents to review
    Work-order history for the unit, the manufacturer’s service instructions, warranty terms, the service contract and last technician report.
    Check visually
    Filters, coil condition, belt wear pattern, pulley alignment, condensate drain, panel logbook. Stay on the ground or use safe access with a second person. Do not open electrical panels.
    Instruments or specialists
    Alignment tools and vibration check by an HVAC technician. Refrigerant work by an EPA-certified technician.
    Potential deficiency
    No preventive schedule; repeat repair without root-cause analysis; incomplete records.
    Location and evidence
    Unit tag RTU-3, photos of belts, filters and coil, work-order printout with dates.
    Immediate risk
    Loss of cooling in occupied space. Also safety on the roof (access, fall protection). Not a life-safety failure.
    Who is notified
    Principal (impact on occupancy), HVAC contractor, purchasing if the contract needs changing.
    Prioritize and verify
    High before the school year, then Medium for ongoing service. Verify with a completed service report and a run-test record.
    Records to keep
    Service report, photos, belt part numbers, new schedule entry.
    Demonstration B: Fire extinguisher inspection records
    Looking for
    Monthly inspection initials and an annual maintenance record for each extinguisher.
    Why it matters
    An extinguisher with a low gauge or blocked access may be useless when needed. For covered employers the OSHA rule requires monthly visual inspection and an annual maintenance check with a record.
    Documents to review
    Inspection log, service-vendor reports, tags, adopted fire-code requirements.
    Check visually
    Location, mounting, access, pressure gauge in the green, seal and pin, tamper indicator, tag date, signs. Do not discharge or recharge.
    Instruments or specialists
    Annual maintenance and hydrostatic tests by a qualified service company.
    Potential deficiency
    Missing monthly records, expired tags, blocked access, low gauge.
    Location and evidence
    Extinguisher number or location, photo of tag, log pages.
    Immediate risk
    Low gauge or missing unit in a high-hazard area is urgent. Others are routine.
    Who is notified
    Custodial supervisor (monthly checks), extinguisher service vendor.
    Prioritize and verify
    Medium for record gaps; High for unusable units. Verify by a completed monthly round and vendor tag.
    Records to keep
    Monthly log, annual service reports, hydrostatic test records.
    Demonstration C: The boiler inspection certificate
    Looking for
    A current state inspection certificate posted or on file for each covered boiler and pressure vessel.
    Why it matters
    Boilers can fail violently. Many states require periodic third-party inspection and certificates for covered equipment.
    Documents to review
    Certificates, inspector reports, relief-valve tests, operator logs, state program rules.
    Check visually
    Certificate date, nameplate, relief-valve discharge piping, general condition, leaks or scale. Do not adjust controls.
    Instruments or specialists
    Internal and external inspection by a commissioned boiler inspector; combustion tuning by a qualified technician.
    Potential deficiency
    Expired or missing certificate; failed relief-valve test; unresolved inspector comments.
    Location and evidence
    Mechanical room, equipment tag, photo of certificate and nameplate.
    Immediate risk
    Depends on the equipment and inspector comments. An expired certificate may require shutdown under state rules.
    Who is notified
    Superintendent, state boiler program or insurer, boiler inspector.
    Prioritize and verify
    High. Verify with a new certificate and cleared inspector comments.
    Records to keep
    Certificates, inspector reports, correspondence.

    2.9Annotated visual#

    Figure 2.1Condition over time: maintained versus neglected
    Conceptual drawing with invented values, not data from any building. The shapes show behavior: neglect lets small defects grow into damage to other parts, so condition falls faster. What to learn Maintenance does two things. It delays the renewal point, and it keeps the asset above the level where failure becomes likely. The cost of neglect appears late, when the curve turns down.
    Tool 2.1Expected annual cost: how many service visits?

    A fictional rooftop unit. Move the inputs and watch the total-cost curve. The model assumes each visit cuts failure risk by a fixed proportion. That is a teaching simplification, not a measurement.

    2.11Realistic case study: The January Boiler#

    Fictional case
    Westbank Annex and the people in it are invented. The case is a composite of patterns, not a record of a real event.

    What happened. Westbank Annex ran on two 1990s boilers. For three years the annual boiler service was deferred to save money, and one boiler had been shut down in each of the last two heating seasons for a “minor leak.” In the first week of January a cold snap arrived. The remaining boiler tripped on low water, and the technician found that a feedwater valve and the water-treatment program had both been neglected. Scale in the unit had been building for years. With temperatures near freezing, the school closed for three days while a rental boiler was craned onto the roof. Pipes froze in one wing. The district paid rental, rigging, emergency labor, plumbing repairs and lost instructional days.

    Root causes.

    • Service was cut first because it left no visible effect.
    • Equipment with redundancy was left with a single working unit and no one noticed.
    • The state inspection certificate was current, so leadership assumed the plant was sound. A certificate shows a legal minimum, not reliability.
    • No condition data was reported to the budget committee.

    Model answer. Treat boilers as critical assets with preventive service and water treatment that cannot be deferred without a documented risk decision. Track redundancy as a status: “N+1 available” or “no spare.” Report to the board when redundancy is lost. Present the cost of deferral in dollars and in days of closure.

    Instructor discussion prompts
    1. Who should have been told when the first boiler was shut down?
    2. How would you present the cost of the deferred service so a board would act?
    3. What does a current state certificate prove, and what does it not prove?
    4. What interim protection could have reduced the freeze damage?

    2.12Sample inspection findings and documentation#

    Fictional data

    2.13Risk classification and corrective actions#

    Use the matrix from Chapter 1. For maintenance findings, ask two extra questions: is a mandatory inspection overdue, and does the asset have a backup? Either answer raises the rating. An overdue mandatory inspection of a pressure vessel is never Low, even if the vessel looks fine.

    Tool 2.2Strategy selector

    Answer five questions about an asset. The result is a starting point for discussion with your technicians. It does not replace a legal duty (those come first) or an engineer’s advice.

    Exercise 2.1Classify ten work orders

    Choose the maintenance type for each work order. Answers and reasons appear after each choice.

    Corrective-action planning. Write maintenance fixes as recurring tasks with an interval, a responsible person, a record and a verification. A one-time repair fixes today’s problem. A scheduled task fixes next year’s.

    2.14Common mistakes and professional lessons#

    • Cutting preventive service first. Its savings are visible now and its cost arrives later and elsewhere.
    • Closing work orders without checking. “Complete” should mean verified.
    • Copying intervals from the internet. Read the adopted standard or the manufacturer manual.
    • Confusing a certificate with reliability. A current certificate is a legal floor.
    • Ignoring redundancy status. Two boilers with one broken is one boiler.
    • Servicing everything the same way. Spend effort where failure matters.
    • No data to defend the budget. Track repeat repairs, emergency cost and downtime.

    2.15Field checklist: preventive-maintenance program audit#

      2.16Knowledge check#

      2.17Key takeaways#

      Remember
      • Mandatory inspections come first; everything else is a strategy choice.
      • Preventive, predictive, corrective and reactive each have a place. Reactive by neglect on a critical asset is the failure.
      • Match effort to criticality and failure behavior.
      • Repeat repairs mean find the root cause.
      • A current certificate is a floor, not a guarantee.
      • Track redundancy, backlog and emergency cost so you can defend the budget.

      Asset Inventories, Condition Assessments and the Facility Condition Index

      You cannot manage, fund or defend what you have not counted and graded. How do you count a building?

      Chapter 3 of 20

      3.1Opening scenario#

      Fictional scenario · Magnolia Annex and Pelican Parish Schools are invented

      Marcus Boudreaux inherited the facilities job at Pelican Parish Schools on a Monday and a spreadsheet on Tuesday. The spreadsheet listed 212 “assets” for nine buildings. It had one row for “HVAC” at Magnolia Annex, valued at $0, and no rows for the roof, the fire pump or the elevator.

      That week the superintendent asked a simple question before the budget meeting: “Which building needs the most money, and how do you know?” Marcus had opinions. He had no numbers. A board member asked, reasonably, why anyone should fund an opinion.

      It took him six weeks to build an inventory, grade the major systems and compute a Facility Condition Index for every building. The first number he showed the board was not a surprise to anyone. What changed was that he could show where it came from.

      This chapter shows how to build that evidence in a way a skeptic can check.

      3.2Learning objectives#

      1. Explain what an asset register is and list the minimum fields each record needs.
      2. Describe the hierarchy from site to component and why it matters for reporting.
      3. Run a basic condition assessment with a consistent rating scale.
      4. Define deferred maintenance, renewal need and replacement value, and keep them apart.
      5. Calculate and interpret the Facility Condition Index and explain its limits.
      6. Rank buildings using both FCI and criticality, with life-safety items handled separately.

      3.3Why the subject matters#

      • Budgets are won with evidence. A board funds a number with a method behind it faster than it funds a complaint.
      • Failures hide in unlisted assets. The fire pump nobody counted is the one nobody tests.
      • Insurance, grants and audits ask. Lenders, insurers and funders often want inventories and condition information. What each requires depends on the contract or program, so read it.
      • Capital planning needs a baseline. You cannot plan renewal of equipment you cannot age.
      • Comparisons need one yardstick. Without a common rating scale, every building looks worst to the person who works there.

      3.4Plain-English technical explanation#

      What an asset register is

      An asset register (or inventory) is a list of the things you maintain, with enough information on each to find it, identify it, age it, value it and schedule its care. It is a living record, not a one-time project.

      Hierarchy

      Group assets so they can be reported at different levels. A common structure runs site, building, floor or area, system, component. The same rooftop unit then rolls up to the roof system, the HVAC system, the building and the portfolio, depending on who is asking.

      Condition assessment

      A condition assessment is a structured walk and records review that grades each system or asset on a fixed scale and estimates the work needed to bring it back to an acceptable state. A property condition assessment done for a purchase or loan follows an agreed scope, often built on a consensus guide such as ASTM E2018. Check the edition and the scope your lender or owner actually requires.

      The Facility Condition Index

      FCI compares need to value:

      Formula
      FCI = deferred maintenance (renewal need) ÷ current replacement value. A building with $2.4 million of identified need and a $12 million replacement value has an FCI of 0.20, or 20%.

      Organizations define the numerator differently (some count only deferred maintenance, others add near-term renewals), and the rating bands also vary. Chapter 1 used the common teaching bands of under 5, 5 to 10, 10 to 30 and over 30 percent. Treat any published band as a convention. Always state your definition when you quote an FCI.

      Limit
      FCI is a financial ratio. It does not say whether a building is safe, and a large new building can look better than a small old one for the wrong reason. Rank life-safety deficiencies by risk, not by FCI.

      3.5Applicable laws, codes, standards and official references#

      Inventory and condition work is mostly a management practice. These are the places where an outside rule or contract can set content or timing.

      3.6How to decide whether a requirement applies#

      1. Does a statute or rule require a record? Asbestos plans for schools, certificates for regulated equipment. Those entries are mandatory fields.
      2. Does a contract or funder require a format or a schedule? Bond covenants, grant terms, insurance schedules.
      3. Does your finance office have a capitalization policy? Align the register to it so the numbers reconcile.
      4. Is there an organizational standard? A district rating scale, if one exists, beats a new one.
      5. Only then choose fields, scale and cycle that fit the staff you have.

      3.7Building systems, components and terminology#

      Asset tag / ID

      A unique, stable identifier physically attached or painted on the asset, and written in the register.

      Current replacement value (CRV)

      What it would cost today to replace the building or asset with something equivalent. Not market value, and not the original cost.

      Deferred maintenance

      Maintenance or repair that was due and has not been done, so it now sits in the backlog.

      Renewal (capital) need

      Replacement of a system that has reached the end of its useful life. Often counted with or beside deferred maintenance.

      Criticality

      How much it matters if the asset fails: safety, mission or cost. Drives priority independent of FCI.

      Rating scale

      A fixed set of grades, with written definitions, so two assessors give the same grade to the same condition.

      3.8Step-by-step inspection demonstration#

      Fictional facility
      Magnolia Annex, Pelican Parish Schools, 1978 building with a 2004 addition. Marcus assesses the roof and the main electrical room. Assessments grade condition. They are not code inspections, and electrical equipment is looked at, never opened.
      Demonstration A: Grading the roof system
      Looking for
      Age, drainage, membrane condition, flashing, penetrations and evidence of leaks.
      Why it matters
      Roofs are expensive, and water damage spreads into walls, ceilings and electrical equipment.
      Documents to review
      Installation date, warranty, past repair invoices, leak work orders, any roof-consultant report.
      Check visually
      From the ground and from interior ceilings first: stains, sagging tiles, damp odor. Roof access only with fall protection and a second person, or hire a qualified roofer.
      Instruments or specialists
      A roofing consultant may use infrared or moisture surveys. Not needed for a first-pass grade.
      Potential deficiency
      Ponding after rain, open seams, failed flashing, clogged drains, repeated patching.
      Location and evidence
      Roof section A (2004 addition) and section B (1978). Photos, ceiling-stain map, work orders by date.
      Immediate risk
      Active leaks over the electrical room or classrooms raise priority at once.
      Who is notified
      Principal for any interior water; roofer for repair estimate.
      Prioritize and verify
      Rate each section on the written scale, estimate renewal cost, and re-check after the next heavy rain.
      Records to keep
      Grade, date, photos, cost estimate with its basis, warranty status.
      Demonstration B: Building a first register for one mechanical room
      Looking for
      Every piece of equipment, even the ones with no tag.
      Why it matters
      Unlisted equipment is unmaintained equipment.
      Documents to review
      As-built drawings, equipment schedules, O&M manuals, vendor invoices.
      Check visually
      Read nameplates. Photograph each plate. Note missing tags and illegible plates.
      Instruments or specialists
      A phone camera and a notebook are enough to start.
      Potential deficiency
      Equipment missing from the register; no tag; no known age.
      Location and evidence
      Mechanical Room M-1: nameplate photos, drawing sheet numbers.
      Immediate risk
      None from the inventory itself. If you see a trouble light, leak or odor, notify the responsible person.
      Who is notified
      Maintenance supervisor; finance office if valuation fields are affected.
      Prioritize and verify
      Tag critical items first. Verify by walking the register against the room.
      Records to keep
      Register rows, photos, the date and the name of the person who counted.

      Tool 3.1Condition assessment and FCI by system

      A fictional building. Grade each system from 1 (critical) to 5 (good). The tool converts grades into an illustrative share of replacement value needing renewal, adds the amounts and reports an FCI. The percentages are teaching assumptions, not an industry standard. Real assessments cost out specific work items.

      3.11Realistic case study: The Two Buildings#

      Fictional case
      Both buildings and the district are invented. The case is a composite of patterns.

      What happened. Pelican Parish Schools had limited capital funds and two candidates for the first project. Magnolia Annex had an FCI of 14 percent and was the largest request. Bayou Crossing Elementary had an FCI of 9 percent, mostly in one system: a 26-year-old fire alarm panel with failing devices, and a sprinkler valve that the last inspection had tagged for repair.

      A first ranking by FCI alone funded Magnolia. Marcus noticed that the Bayou Crossing items were life-safety findings from a recorded inspection, not renewal wishes. He moved them out of the FCI queue and into the risk queue, where they were scheduled for correction first. The sprinkler repair cost a few thousand dollars. The alarm replacement was phased across two years with interim measures approved by the fire authority.

      What went right. The register held test dates and findings, so the life-safety items were visible. The FCI was still useful. It guided the larger renewal money.

      What went wrong at first. The initial list used one score for everything. The correction was to separate “is anyone at risk now?” from “what is the long-run renewal need?”

      Lessons. (1) FCI ranks money. Risk ranks urgency. (2) Keep findings and test dates in the register. (3) When a life-safety system is impaired, notify the responsible authority, use the interim measures it requires, and fix it first.

      3.13Risk classification and corrective actions#

      Two separate questions run side by side:

      • Risk now: Does the condition endanger people or stop the mission? Use the Chapter 1 matrix and its life-safety override. Act first.
      • Money over time: How much renewal is coming, and when? Use condition grades and FCI to plan capital funds.

      An asset can score high on one and low on the other. A rusty but redundant storage-yard fence has a poor grade and low risk. A new-looking sprinkler valve closed by mistake has a good grade and a high risk.

      Corrective-action planning. For each finding record the cause, the fix, an owner, a date, how you will verify, and whether the cost belongs in the operating budget or the capital plan. Reassess on a stated cycle, and after major work.

      3.14Common mistakes and professional lessons#

      • Using original cost as replacement value. It makes old buildings look cheap to replace and the FCI too high or too low.
      • Skipping the grade definitions. Without written definitions, grades are opinions.
      • Letting FCI rank safety. It ranks money.
      • Treating the register as a one-time project. Update on every install, removal and assessment.
      • Quoting FCI without its definition. Say what is in the numerator and what bands you use.
      • Trusting a lone assessor. Calibrate two people on the same room and compare.

      3.15Field checklist: inventory and condition assessment#

        3.16Knowledge check#

        3.17Key takeaways#

        Remember
        • A register records what you maintain, where it is, how old it is and what it is worth.
        • Use a hierarchy and record each asset once, with a parent.
        • Condition grades need written definitions and a second assessor.
        • FCI is deferred need divided by replacement value. State your definition.
        • FCI ranks money. Risk ranks urgency. Life-safety items go first.
        • Reconcile valuation with your finance office.

        Risk-Based Prioritization

        When everything is urgent, how do you decide what happens first, and defend the order?

        Chapter 4 of 20

        4.1Opening scenario#

        Fictional scenario · Harbor Point High School and its people are invented

        On Friday afternoon Renee Castillo, facilities director at Harbor Point High, had fifteen open items on her desk and a crew of four. The principal wanted the gym floor refinished before homecoming. The band director wanted the practice-room air conditioner fixed. A custodian had mentioned, almost in passing, that a stairwell exit door was chained at night “to stop kids sneaking out.”

        The loudest request was the gym floor. The quiet one was the door. Renee sent the custodian to cut the chain, and she did it before anything else was discussed. She did not need a formula to know which came first. She needed one to explain the rest of the order to a principal who thought the gym floor was number one.

        This chapter gives you that formula, the rule that sits above it, and a way to write down the reasoning so an auditor or board member can follow it.

        4.2Learning objectives#

        1. Score a deficiency by likelihood and consequence on a defined scale.
        2. Apply the life-safety override and explain why it sits above any score.
        3. Name the other factors that raise priority: overdue mandatory duties, exposure, redundancy and cost of delay.
        4. Recognize what an imminent-danger condition is and who must be told.
        5. Rank a mixed list of deficiencies and defend the order in writing.
        6. Avoid the common biases: loudest voice, easiest fix, newest item.

        4.3Why the subject matters#

        • Resources are finite. Every list is longer than the crew and the budget.
        • The squeaky wheel is not the risk. Complaints measure annoyance. Risk measures harm.
        • A recorded decision protects people and the organization. If a dangerous item was known and left, the record shows who knew what, when and what they did.
        • Consistency builds trust. Staff accept an order they can see the reasons for.
        • Money follows ranked evidence. A ranked list with a method is a budget request that survives questions.

        4.4Plain-English technical explanation#

        The basic score

        Risk score = likelihood × consequence. Both use a 1 to 5 scale with written definitions.

        ScoreLikelihood (that harm or failure occurs)Consequence (if it does)
        1Rare: not expected in the life of the assetNegligible: nuisance, no injury, no lost use
        2Unlikely: could happen once in several yearsMinor: first aid, short inconvenience
        3Possible: could happen within a yearModerate: medical treatment, a room or system out of use for days
        4Likely: has happened here or will probably happen this yearMajor: serious injury, a building area closed, large cost
        5Almost certain: happening now or expected within weeksSevere: death or life-changing injury, school or building closure, regulatory action

        Bands used in this book, as in Chapter 1: Critical at 20 or more, High at 10 to 19, Medium at 5 to 9, Low below 5. They are illustrative. Adopt your own organization’s bands if it has them and keep them stable over time.

        The life-safety override

        Rule
        Any condition that could keep people from detecting a fire, getting out, or being protected from fire or other life-threatening hazard is rated Critical regardless of its score, until it is made safe. A chained exit door, a closed sprinkler control valve, a silenced alarm and a blocked egress path all qualify.

        Adjusters that raise or lower priority

        AdjusterQuestionEffect
        Mandatory duty overdueIs a required inspection, test or certificate past due?Raise one band. Past-due pressure-vessel or fire-protection work is not Low.
        ExposureHow many people, and how often, are exposed?A hazard in a gym during events outranks the same hazard in a seldom-used storage yard.
        RedundancyIs there a working backup?Loss of the only boiler is worse than loss of one of two working boilers.
        Cost of delayDoes the damage grow if left, for example a roof leak?Raise priority when delay multiplies the cost.
        Quick, cheap fixCan it be fixed today for little cost?Do it now. Cheap fixes should not wait for ranking.

        4.6How to decide whether a requirement applies#

        1. Is there an order, notice of violation or imminent-danger finding? Follow its deadline. Notify the responsible people at once.
        2. Does the condition touch a life-safety system? Apply the override. Make it safe first.
        3. Is a mandatory duty overdue? Raise one band.
        4. Score the rest by likelihood and consequence.
        5. Adjust for exposure, redundancy, cost of delay.
        6. Record the score, reasons and who approved.

        4.7Building systems, components and terminology#

        Hazard

        A source of potential harm: a trip edge, an energized part, a blocked exit.

        Risk

        The combination of how likely harm is and how bad it would be.

        Interim measure

        A temporary control that makes a condition safe until the permanent fix: barricade, fire watch, closed room.

        Imminent danger

        A condition expected to cause death or serious harm immediately. Remove people first.

        Impairment

        A fire-protection system that is out of service or partly out of service. Needs notice, interim protection and tracking.

        Risk register

        The written list of items, scores, owners and status, reviewed on a schedule.

        4.8Step-by-step inspection demonstration#

        Fictional facility
        Harbor Point High School. Renee walks the building with a custodian and the maintenance lead. Nobody opens electrical equipment. A person who finds an immediate danger removes people from it and calls the responsible person first, and documents second.
        Demonstration A: The chained exit door
        Looking for
        Whether every exit door opens from the inside without a key, tool or special knowledge, and whether anything blocks the path.
        Why it matters
        In a fire or emergency, people must get out quickly. A chain turns a door into a trap.
        Documents to review
        Egress plan, fire-marshal inspection report, any past notices.
        Check visually
        Every exit door, the hardware, signs and lighting, and the path outside the door. Look for chains, extra locks, wedged items and blocked discharge.
        Instruments or specialists
        None needed to see a chain. Door-hardware questions go to the fire marshal or a door specialist.
        Potential deficiency
        Egress obstructed or locked against exit.
        Location and evidence
        North stairwell exit, door 1N. Photo of chain and padlock, date and time.
        Immediate risk
        Critical. Life-safety override applies. Remove the chain now with the principal’s approval.
        Who is notified
        Principal at once; superintendent and the fire marshal as required by your procedures.
        Prioritize and verify
        Critical regardless of score. Verify by opening the door from inside, and re-check at night and on weekends.
        Records to keep
        Photo, time of removal, who authorized, follow-up plan for the underlying concern (after-hours security).
        Demonstration B: The gym floor and the practice-room air conditioner
        Looking for
        Real harm potential versus inconvenience or appearance.
        Why it matters
        Both requests are legitimate. Neither threatens life.
        Documents to review
        Work orders, event calendar, floor warranty, HVAC history for the practice rooms.
        Check visually
        Floor surface for trip hazards or loose boards. Practice-room temperature and condensation.
        Instruments or specialists
        A thermometer; a flooring contractor for loose boards.
        Potential deficiency
        Worn floor finish: appearance. Loose boards: injury risk. Failed AC: comfort and instrument damage.
        Location and evidence
        Gym floor sections 3 and 4; practice rooms P1 to P3. Photos and readings.
        Immediate risk
        Loose boards: Medium to High until repaired. Finish wear: Low. AC: Medium.
        Who is notified
        Athletic director and band director, with the ranking reasons.
        Prioritize and verify
        Fix loose boards before the next event. Schedule the rest by score and calendar.
        Records to keep
        Score sheet with reasons and the explanation sent to requesters.

        4.11Realistic case study: The Silenced Panel#

        Fictional case
        Oakline Elementary and the people in it are invented. The case is a composite of patterns, not a record of a real event.

        What happened. A fire-alarm panel at Oakline Elementary kept going into trouble every few days because of a failing detector. A staff member silenced the trouble signal each time. After two months, the trouble light was simply normal to everyone in the office. A week before a state inspection, a contractor found that one wing’s devices had been disconnected from the panel for six weeks.

        Ranking. By the score, a trouble signal looked like a Low maintenance item. By the override rule it was Critical: an alarm that cannot warn a wing is an impairment of a life-safety system. The district notified the responsible people the same day, posted a fire watch with the approval of the authority, repaired the detectors and recorded the dates.

        What went wrong. Nobody owned the question “what does this light mean?” Silencing became the response, and silence became the habit.

        Lessons. (1) A trouble signal is a message, not a nuisance. (2) Treat impairments as Critical until interim protection is in place and the authority is informed as required. (3) Train front-office staff on what to do, not just how to silence.

        4.13Risk classification and corrective actions#

        Write each decision so a stranger can follow it. A short record has five parts:

        1. What is the condition? Location, evidence, date.
        2. Who or what is exposed?
        3. Scores and adjusters with the override noted.
        4. Action and owner: interim measure now, permanent fix later, with dates.
        5. Verification: how and when you will check it worked.
        Escalation
        If the condition could cause death or serious harm immediately, treat it as imminent danger: remove people, notify the responsible person at once and follow your emergency procedures. Do not wait to finish the paperwork.

        Review the register on a schedule: Critical items daily until safe, High weekly, Medium monthly, Low at each assessment cycle.

        4.14Common mistakes and professional lessons#

        • Ranking by complaint volume. Complaints measure annoyance.
        • Letting a high score overrule a clear override. Safety rules sit above the arithmetic.
        • Scoring alone. Two assessors on the same item catch drift.
        • Rating everything High. A list with no Low items has no priorities.
        • Skipping the explanation to requesters. People accept a lower rank when they can see the reasons.
        • Leaving cheap fixes in the queue. Do them now.

          Tamika Reed, operations director at Lakeview Charter Academy, had two roof quotes on her desk. The first was $410,000 for a roof with a 15-year life. The second was $560,000 for one with a 30-year life. The board chair had already circled the first number. “We are $150,000 apart. Why would we pay more?”

          Tamika did not answer with an opinion. She went home and built a table: the cost of each roof today, the yearly upkeep, the replacement at year 15 for the short-lived roof, and what a dollar later is worth compared with a dollar now. By the next meeting she could say that over thirty years, the cheaper roof would cost the school more.

          The board still had to decide how to pay for it. Roofs are not operating expenses, and the school’s budget had no line for them. That was the second conversation, and it was harder.

          This chapter covers both: how to compare options over their life, and how to build a budget that has a place for renewal.

          5.2Learning objectives#

          1. Distinguish operating expense (OpEx) from capital expense (CapEx) and say who decides which is which.
          2. Explain lifecycle cost and total cost of ownership.
          3. Compute a present-value comparison of two options over a study period.
          4. Estimate an annual renewal reserve from replacement cost and useful life.
          5. Build a facility budget with operating, reserve and contingency lines.
          6. Write a budget request that a board or auditor can follow.

          5.3Why the subject matters#

          • Low bids hide high costs. Purchase price is often a minor share of what an asset costs over its life.
          • Deferred maintenance is borrowing. The cost does not vanish. It returns later, usually larger and at a worse time.
          • Budget categories steer behavior. If there is no renewal line, renewal is skipped until failure.
          • Public and grant money has rules. Procurement and appropriation law, bond terms and grant conditions limit what you can buy and how.
          • Boards need a number with a method. A structured comparison turns an argument into a decision.

          5.4Plain-English technical explanation#

          Who sets the lineYour finance office and auditor, through a written capitalization policy. The facility manager follows it and does not invent it.
          Caution
          The same dollar can be OpEx in one organization and CapEx in another, depending on the capitalization threshold and policy. Ask your finance office for the written policy before you label a request.

          Lifecycle cost

          Lifecycle cost (or total cost of ownership) adds up everything an asset costs over a chosen study period: purchase and installation, operation, maintenance, repair, replacement at end of life, and any residual value at the end.

          Time value of money

          A dollar next year is worth less than a dollar today. Present value converts future costs into today’s dollars using a discount rate. If the discount rate is 4 percent, $1,000 spent in a year costs about $962 today. Escalation (cost inflation) works in the opposite direction. This chapter uses a simple model with both, and says plainly when a number is an assumption.

          Formulas
          Present value of a future cost = cost ÷ (1 + r)t for a one-time cost at year t. For an annual cost, add the present value of each year. Annual renewal reserve ≈ replacement cost ÷ useful life. A roof that costs $560,000 and lasts 30 years needs about $18,700 set aside every year to pay for itself.

          The reserve idea

          If every system in a building will need replacement someday, the budget should set money aside each year instead of waiting for a surprise. Summed across systems, that annual amount is a rough renewal reserve. Compare it with what you actually spend to see the gap.

          5.6How to decide whether a requirement applies#

          1. Who is the owner and what is its legal type? Public body, charter operator, private owner. Procurement rules differ.
          2. What is the funding source? Operating budget, bonds, grants, insurance proceeds, reserves. Each has conditions.
          3. Is the purchase above a bid or approval threshold? Ask procurement for the current limits.
          4. Is it capital under your policy? Ask finance.
          5. Does an emergency exception apply? Emergency purchasing is usually narrow and needs documentation. Ask before assuming.
          6. Then compare options by lifecycle cost.

          5.7Building systems, components and terminology#

          Total cost of ownership

          All costs over the life of an asset, not only the purchase price.

          Study period

          The span of years you compare options over, such as 30 years.

          Discount rate

          The rate used to convert future dollars into present value. Choose it with your finance office.

          Escalation

          Expected annual rise in costs.

          Residual value

          Value left at the end of the study period. Often the unused share of a replacement’s life.

          Contingency

          A reserve inside a project or budget for unknowns, stated as a percentage of cost.

          Renewal reserve

          Money set aside each year toward future replacements.

          Capital plan

          A multi-year list of renewals and projects with costs and years.

          Demonstration A: Comparing two roof quotes
          Looking for
          Whether the quotes cover the same scope, warranty and life, and what each really costs over 30 years.
          Why it matters
          A lower price for a shorter-lived roof can cost more over time.
          Documents to review
          Both quotes and specifications, warranty terms, roof-consultant report, past leak and repair history.
          Check visually
          Current roof from the ground and from the interior ceilings. Roof access only with fall protection and a second person, or a qualified roofer.
          Instruments or specialists
          A roof consultant to verify scope and condition. An engineer if structure is in question.
          Potential deficiency
          Quotes that do not match in scope; no maintenance plan; assumptions not written down.
          Location and evidence
          Main building roof sections A to C. Quotes, photos, leak history.
          Immediate risk
          Interior leaks over occupied rooms or electrical equipment raise priority.
          Who is notified
          Board chair and finance office, with the method and the assumptions.
          Prioritize and verify
          Run the comparison with assumptions stated and a sensitivity check. Verify scope with the roof consultant.
          Records to keep

          Demonstration B: Auditing the facility budget for a renewal line
          Looking for
          Whether any money is set aside for replacement of roofs, HVAC, paving and other major systems.
          Why it matters
          No renewal line means renewal waits for failure.
          Documents to review
          Operating budget, capital plan, reserve balances, prior-year actuals, work-order spending by category.
          Check visually
          Compare equipment ages in the register to the plan. Walk mechanical rooms and roof edges from safe positions.
          Instruments or specialists
          Finance office for policy and reserves.
          Potential deficiency
          Zero reserve; emergency repairs paid from operating money; capital plan out of date.
          Location and evidence
          Budget lines and ledger extracts, with dates.
          Immediate risk
          Usually financial. If a failed system endangers people, apply Chapter 4.

          Tool 5.1Lifecycle cost: two options over a study period

          Fictional roofs. The model adds the initial cost, the present value of yearly upkeep and of each replacement inside the study period, and subtracts the unused share of the last roof’s life at the end. All rates are assumptions. Change them and watch how the answer moves.

          OptionInstalled cost ($)Upkeep per year ($)Life (years)
          A: lower price, shorter life
          B: higher price, longer life
          Tool 5.2Annual renewal reserve estimate

          Fictional building. Enter replacement cost and useful life for each system. The tool sums replacement cost divided by life and compares it with the amount your budget sets aside. It is a rough guide that ignores inflation and the age of the assets, so treat the result as a floor for the conversation.

          5.11Realistic case study: The Cheapest Roof#

          Fictional case
          Delta Ridge School and the people in it are invented. The case is a composite of patterns, not a record of a real event.

          What happened. Delta Ridge chose the lowest bid for a gym roof. The product had a 12-year life, but the specification said only “roof, complete.” At year 11 the roof began to leak. The district found that the original warranty had expired and that the manufacturer’s upkeep schedule had never been followed. A replacement ate the next year’s capital fund and delayed a boiler project that had been scheduled for that year.

          What a lifecycle comparison would have shown. Over a 30-year period, the cheaper roof needed two replacements and more upkeep. The premium option cost about a third more at the start and less over 30 years under most reasonable assumptions.

          What went wrong. The specification did not require a minimum life or a maintenance plan, and nobody compared total cost. The budget had no reserve, so the replacement landed on a project that was ready to go.

          Lessons. (1) Write minimum life and warranty terms into the specification, within procurement rules. (2) Compare total cost, not price. (3) Fund renewal on a schedule, not on failure.

          5.12Sample inspection findings and documentation#

          5.13Risk classification and corrective actions#

          Financial findings follow the same discipline as physical ones: state the condition, the exposure, the action, the owner and the check. Two rules apply:

          • Life-safety first. Chapter 4’s override still applies. A budget gap never lowers the rating of an unsafe condition. If money is short, choose interim measures and escalate.
          • Show the options. When asking for funds, present the full set: fix now, phase over years, interim measures, and do nothing. Include the consequence of each.

          A good budget request has six parts: need and evidence; options compared; recommended option and its lifecycle cost; funding source; what happens if it is not funded; who is accountable for delivery.

          5.14Common mistakes and professional lessons#

          • Comparing purchase prices only. The cheaper asset may cost more over its life.
          • Hiding assumptions. Write the discount rate, escalation and life, and test how the answer changes.
          • Calling a repair capital, or a replacement operating, without the policy. Ask finance.
          • Treating a reserve as spare cash. Reserves are earmarked for renewal.
          • Splitting a purchase to dodge a threshold. It is a procurement violation in many places. Ask first.
          • Asking for money without options. A board with one choice feels cornered. Give it the set.

          5.15Field checklist: budget and lifecycle review#

            5.16Knowledge check#

            5.17Key takeaways#

            Remember
            • Your finance office decides what is capital. Ask for the written policy.
            • Lifecycle cost beats price. Compare options over a study period with stated assumptions.
            • Present value converts future dollars into today’s dollars.
            • Annual reserve is roughly replacement cost divided by life, summed across systems.
            • Deferred maintenance is borrowing against the future.
            • Look up procurement limits with the office that owns them. Do not quote them from memory.

            Service Agreements, Contractors, Warranties and Vendor Management

            You are paying for the work. How do you know you got it?

            Chapter 6 of 20

            6.1Opening scenario#

            Fictional scenario · Riverbend Academy and Gulf Coast Mechanical are invented

            Luis Armand took over facilities at Riverbend Academy in August. In his first week he found a folder labeled “HVAC contract.” It held a one-page agreement that said Gulf Coast Mechanical would “service the heating and cooling equipment as needed” for a flat monthly fee. It listed no equipment, no visit schedule, no response time and no reports.

            The invoices came every month. The visit records came never. When a chiller failed in September, the vendor arrived two days later and billed the repair as extra. Luis asked for service reports and was told, politely, that none were required.

            The contract was not a fraud. It was a blank check with a signature on it.

            This chapter is about writing and managing agreements so that paying for work and getting work are the same thing.

            6.2Learning objectives#

            1. Write a scope of work that names the equipment, tasks, frequency and deliverables.
            2. Include response times, reports and acceptance criteria in a service agreement.
            3. Check a contractor’s license, insurance and authority before work starts.
            4. Track warranties so claims are made in time.
            5. Score vendor performance with a consistent method.
            6. Spot weak clauses in an agreement and know when to ask a lawyer.

            6.3Why the subject matters#

            • Most building work is outsourced. Fire protection, elevators, HVAC, roofing and many other systems depend on vendors.
            • A vague contract cannot be enforced. If it does not say what, when and how well, there is nothing to hold anyone to.
            • Required inspections are done by vendors. If the vendor skips a test, the owner still carries the duty.
            • Warranties expire quietly. A defect found on day 366 of a one-year warranty is the owner’s cost.
            • Insurance and licensing protect you. An unlicensed or uninsured contractor moves risk to the owner.

            6.4Plain-English technical explanation#

            Types of agreements

            TypeExampleGood forWatch for
            Service agreement (recurring)Quarterly HVAC maintenance; monthly fire-alarm monitoringRoutine, repeating workVague scope; no reports; auto-renewal
            Project contractRoof replacementOne-time work with defined endChange orders; unclear completion criteria

            WarrantyManufacturer or installer coverageDefects in new equipment or workConditions: required maintenance, registered start date, claim windows

            What a good service agreement states

            1. Scope: which equipment (by tag or list), which tasks, and the standard each follows (manufacturer instructions or an adopted code).
            2. Frequency and schedule: how often, in what window, with advance notice.
            3. Response times: for emergencies, urgent and routine calls, with how they are measured.
            4. Reports: written report after each visit, with findings, readings and recommendations. Payment tied to receipt.
            5. Qualifications: licenses, certifications (for example EPA refrigerant certification for technicians), background checks where required.
            6. Insurance and indemnity: types and limits, with certificates on file.
            7. Pricing: fixed fee, rate sheet, parts markup, what is excluded.
            8. Term and renewal: start, end, whether it renews automatically, notice to cancel.
            9. Acceptance and remedies: how work is accepted, what happens if it is not done.
            10. Records: who owns them and how you get them if the vendor leaves.

            Verification and oversight

            A contract is a promise. Verification is how you find out whether it is kept: read the reports, spot-check the work, compare invoices with visits and keep a scorecard. Do not pay for work you cannot show was done.

            6.6How to decide whether a requirement applies#

            1. Is the buyer a public body? Procurement and public-contract law may apply. Ask procurement.
            2. Does the work need a license? Check the licensing board for the trade and job size. Verify the contractor’s license number and status with the board.
            3. Does the work touch a regulated system or substance? Fire protection, refrigerants, asbestos, pressure vessels, elevators. Require the credentials the rule or the AHJ requires.
            4. Does warranty coverage depend on who does the work? Using a non-approved servicer can void a warranty.
            5. What does the insurer or lender require?
            6. Then write the scope and the oversight plan.

            6.7Building systems, components and terminology#

            Scope of work

            The precise list of tasks, equipment, standards and deliverables the vendor must provide.

            Service-level agreement (SLA)

            Measurable performance promises, such as response within four hours for emergencies.

            Certificate of insurance

            Indemnity

            A promise by one party to cover certain losses of the other. Have counsel review.

            Change order

            A written change to price or scope. Never pay for work that has no written change order.

            Warranty

            A promise to repair or replace defective work or equipment for a period, with conditions.

            Acceptance

            Your formal confirmation that work met the contract.

            Performance bond

            A surety’s guarantee that a project will be completed. Used mostly on larger construction work.

            Potential deficiency
            No equipment list; no reports; visits not logged; vendor credentials not on file.
            Location and evidence
            Main mechanical room and roof units RTU-1 to RTU-6. Photos, logbooks, invoices matched to visits.
            Immediate risk
            Usually financial and reliability. If a regulated system has missed its required tests, treat as higher.
            Who is notified
            Business manager and procurement office. Counsel if a breach is likely.
            Prioritize and verify
            Send a written notice of missing reports. Verify by receiving them and spot-checking.
            Records to keep
            Gap list, notices, vendor replies, revised agreement.

            That the contractor is licensed, insured, qualified and authorized before work begins.
            Why it matters
            An unlicensed or uninsured contractor moves risk to the owner.
            Documents to review
            License record from the licensing board, certificate of insurance, technician certifications, safety plan, proof of any required background checks.
            Check visually
            Sign-in procedures, ID badges, equipment lockout practices if applicable.
            Instruments or specialists
            Licensing board lookup. Insurance broker if the certificate is unclear.
            Potential deficiency
            Expired license or insurance; no named insured; missing certification for refrigerant or asbestos-related work.
            Location and evidence
            Contractor file with dated copies.
            Immediate risk
            Stop work if the contractor lacks a required credential for regulated work.
            Who is notified
            Procurement; risk manager.
            Prioritize and verify
            Do not issue a notice to proceed until the file is complete.
            Records to keep

            Fictional case
            Bluewater Elementary and its contractors are invented. The case is a composite of patterns, not a record of a real event.

            What happened. Bluewater Elementary had a new roof installed under a two-year workmanship warranty. Leaks began in month 23. The facility lead noted them and planned to call the roofer after the holiday break. The break lasted three weeks, the warranty ended on a Tuesday in month 24, and the roofer’s response was courteous: the warranty was over, and the repair would be billed at standard rates.

            What went wrong. Nobody tracked the end date. The leaks were noted but not reported in writing. The warranty required written notice within the term.

            What a tracker would have shown. A 90-day alert in month 21 would have prompted a roof walk with the contractor, and any defect would have been documented while coverage was valid.

            Lessons. (1) Track every warranty end date and set alerts. (2) Give written notice of defects inside the window. (3) Schedule an end-of-warranty inspection a few months before expiry.

            6.13Risk classification and corrective actions#

            Vendor risk comes in four kinds. Rate each with the Chapter 4 method and note which are life-safety.

            • Safety and compliance: a vendor skips a required test or works without a required credential. Treat as high or as the override if a life-safety system is affected.
            • Performance: reliability and response fall short. Medium to high, by criticality of the asset.
            • Financial: overbilling, cost creep, lock-in. Medium.
            • Continuity: a single vendor holds knowledge and records. Plan for transition.

            Corrective-action planning. Send written notices, give a cure period if the contract provides one, record responses, escalate to procurement or counsel before terminating, and line up a replacement for critical services. Do not withhold payment contrary to the contract terms without advice.

            6.14Common mistakes and professional lessons#

            • Paying without reports. No evidence, no payment, if the contract allows.
            • Signing a vendor’s form unread. Have counsel review indemnity, renewal and liability terms.
            • Skipping credential checks. Verify the license and insurance on the source, not from a copy the vendor hands you.
            • Losing warranty dates. Calendar them with alerts.
            • Letting the vendor define success. Write measurable standards into the scope.
            • Single-source dependence. Keep records yourself and know your second choice.

              6.17Key takeaways#

              Remember
              • A scope that says “as needed” cannot be enforced. Name equipment, tasks, frequency and reports.
              • Check license, insurance and certifications before work starts.
              • Pay against evidence of the work, not against the calendar.
              • Track warranty end dates and give written notice inside the window.
              • Score vendors on the same criteria every time. Safety weighs most.
              • Have counsel review contracts. This book is not legal advice.

              Work Orders, Records and KPIs

              If it is not written down, did it happen? And if you cannot measure it, can you improve it?

              Chapter 7 of 20

              7.1Opening scenario#

              Fictional scenario · Oak Terrace Elementary and its staff are invented

              After a minor kitchen fire, the district’s insurer asked Gloria Mensah, facilities coordinator at Oak Terrace Elementary, for the last three years of fire-suppression inspection records. She had a binder, a dozen emails and a spreadsheet maintained by a person who had since retired. The monthly extinguisher checks were initialed through spring and then stopped. The vendor’s annual test report for the kitchen hood system was missing for one year.

              The fire itself was small. The paperwork gap was not. The insurer’s adjuster did not accuse anyone of anything. He asked a polite question and waited for an answer she did not have.

              That week Gloria began a work-order system with one rule: if work is done, it is recorded the same day. A year later she could answer the same question in ten minutes, and the numbers also told her which buildings were running on repairs and which on plans.

              This chapter covers how to design work orders, keep records that stand up to questions and pick a few measures that change decisions.

              7.2Learning objectives#

              1. Describe the life of a work order from request to analysis.
              2. List the minimum fields of a work-order record.
              3. Identify which records are required by law and which are good practice, and look up retention periods at their source.
              4. Compute and interpret core maintenance KPIs.
              5. Spot misleading metrics and avoid gaming.
              6. Design a monthly report that leads to a decision.

              7.3Why the subject matters#

              • Records are the evidence of due care. Insurers, inspectors, auditors and courts ask for them.
              • Required inspections are only as good as their records. A test done and not recorded is, for most purposes, a test not done.
              • Patterns hide in single repairs. Repeat failures show up only when jobs are recorded against assets.
              • Budgets follow data. Chapters 3 to 5 rely on a register and cost history that work orders feed.
              • What is measured gets attention. The wrong measure gets the wrong attention.

              7.4Plain-English technical explanation#

              The work-order lifecycle

              A work order is a written record of a job: what, where, why, who, when and what happened. Every job, from a changed lamp to a roof replacement, follows the same steps in some form: request, triage, approve, plan and schedule, perform, verify and close, analyze. Triage assigns the Chapter 4 priority. Verification confirms the work met the request. Analysis feeds the register and the budget.

              Minimum fields

              Date completed and who verifiedClose with evidence
              Failure cause (when known)Root-cause trends

              Records

              Beyond work orders, a facility keeps: inspection and test reports, certificates, permits, drawings and manuals, warranties, training records, incident reports and contractor files. Some are required by law with set retention periods. Others are good practice. Know which is which, and keep a retention schedule approved by your organization’s records officer or counsel.

              KPIs

              A key performance indicator is a number that tells you whether you are meeting a goal. A few examples:

              KPIFormulaWhat it tells youCaution
              Preventive-maintenance compliancePM tasks completed on time ÷ PM tasks dueWhether the plan is actually carried outCounting a PM as done without checking quality
              Reactive shareReactive work orders ÷ all work ordersHow much of the work is firefightingSome reactive work is fine (Chapter 2)
              Mean time to complete, by priorityAverage days from request to verified closureSpeed of response and flowClosing early to hit the number
              Backlog ageOpen items older than a set number of daysWhether work is waiting foreverCancelling items to shrink it
              Reopen rateWork orders reopened ÷ closedQuality of repairsNot recording a reopened job as new
              Cost per square footMaintenance spend ÷ areaRough comparison between buildingsIgnores age, use and condition
              Warning
              People change behavior to hit a number. If the measure is closing time, work gets closed before it is done. Pair every speed measure with a quality measure, such as the reopen rate.

              Retention periods change and differ by record type and jurisdiction. Use Tool 7.2 as a starting map, then confirm with your records officer or counsel. When a legal dispute or investigation is possible, stop routine destruction of related records and ask counsel.

              7.6How to decide whether a requirement applies#

              1. Is a federal rule already verified for this record? Use Tool 7.2 and read the source.
              2. Is your organization a public body? A state retention schedule probably applies. Ask the records officer.
              3. Is there an adopted code or AHJ requirement for the record? Ask the fire marshal or building official.
              4. Does a contract, insurer or funder require more? Use the longest period.
              5. Is a dispute possible? Hold the records and ask counsel.
              6. Then set your own retention schedule and apply it consistently.

              Vendors who perform the tests. The fire official for questions about the adopted code.
              Potential deficiency
              Missing months; dates that do not match tags; vendor reports missing; certificates expired.
              Location and evidence
              Kitchen, mechanical room, corridors. Log pages, tag photos, report copies.
              Immediate risk
              A missing record may mean a missing test on a life-safety system. Verify the test happened or schedule it now.
              Who is notified
              Principal and the vendor; the insurer if an open claim or request exists.
              Prioritize and verify
              Rate with the Chapter 4 method. Verify by receiving the missing reports or performing the tests.
              Records to keep
              Gap list, requests, vendor responses and the date each gap closed.
              Demonstration B: Reading a month of work orders

              Why it matters
              It shows whether the program runs on plans or emergencies.
              Documents to review
              Work-order export for the month, the PM schedule, last month’s report.
              Check visually
              Walk to two assets that appear often in the data and look for signs of the repeat problem.

              Location and evidence
              Assets with three or more orders in the month.
              Immediate risk
              Repeat failure on a critical asset needs a cause review now.

              7.11Realistic case study: The Missing Months#

              Fictional case
              Cedar Hollow School and the people in it are invented. The case is a composite of patterns, not a record of a real event.

              What happened. Cedar Hollow had good inspectors and poor paperwork. After a minor incident, the district’s attorney asked for three years of fire-protection records. Inspectors had done the work. Reports for four of the 36 monthly checks were missing, and the annual alarm test report for one year existed only as an email attachment that nobody could find.

              What it cost. The incident itself caused little harm. The district spent staff time reconstructing records from vendor files, and the attorney advised that the gaps could weaken its position if the matter became a dispute.

              What changed. The district created a shared records folder with a standard naming rule, made the vendor submit the report before payment, and added a monthly check that every required record for the month existed.

              Lessons. (1) A record that cannot be found does not exist. (2) Tie payment to receipt of the record. (3) Check completeness monthly, not after an incident.

              7.13Risk classification and corrective actions#

              Records findings carry two kinds of risk. First, a missing record may hide a missed test on a life-safety system. Treat that as a possible override until the test is confirmed. Second, a missing record is a liability and audit risk in itself. Rate it Medium unless an authority or contract makes it mandatory.

              Corrective-action planning. For each gap: confirm the work was done, obtain or recreate the record without back-dating, note the date of the new record, assign an owner, fix the process that caused the gap and verify next month.

              Never
              Do not back-date or invent records. If a record is missing, write a dated note explaining what you found and what you did. Falsified records turn a paperwork gap into a legal problem.

              7.14Common mistakes and professional lessons#

              • Closing work orders without verification. “Complete” should mean checked.
              • Reporting too many KPIs. Five measures that change decisions beat twenty that do not.
              • Measuring speed without quality. Pair response time with the reopen rate.
              • Keeping records in someone’s inbox. Use a shared, controlled place.
              • Guessing retention periods. Look them up at the source and ask the records officer.
              • Back-dating a missing record. Write an honest dated note instead.

                • Every job gets a work order with asset, priority, work done and a verified closure.
                • Required inspections need dated, findable records. A test not recorded is hard to prove.
                • Know which records are mandatory and look up the retention period at its source.
                • Pick a few KPIs. Pair speed with quality. Watch for gaming.
                • Check completeness of required records monthly.
                • Never back-date. Write an honest dated note.

                Structural Systems, Foundations, Slabs and Roofs

                A building is a set of paths that carry weight to the ground. What does it look like when one of them is in trouble, and what are you allowed to do about it?

                Chapter 8 of 20

                Safety boundary for this chapter
                A facility manager observes, records, monitors and escalates. A licensed structural engineer diagnoses causes and decides on repairs, shoring, load limits and reoccupancy. Do not cut, drill, remove or add load to structural members, and do not enter a space you suspect is unstable. If you see sudden movement, new loud cracking, a sagging ceiling or a door that has jammed overnight, clear the area and call for help.

                8.1Opening scenario#

                Fictional scenario · Marsh Landing Elementary and its people are invented

                A second-grade teacher told Carlos Ibarra, the custodial supervisor at Marsh Landing Elementary, that her classroom door had started sticking. By Friday it needed a shoulder to close. Carlos shaved the door edge with a plane, which fixed the sticking and hid the message.

                In October, a student pointed out a crack that ran diagonally from the top corner of the same door frame. Carlos photographed it, put a pencil mark and date at each end, and sent the photo to the facility manager, Janelle Wheeler. She walked the wing the same afternoon. She noticed a downspout that emptied against the foundation, a flower bed that held water, and a second diagonal crack at the next window.

                She did not guess at the cause. She cordoned off nothing, because nothing suggested immediate danger, but she posted a notice to staff to report any new cracks or sudden movement, and called a structural engineer the same day.

                The engineer found settlement from soil that had been repeatedly saturated by the downspout discharge. Fixing the drainage came first. The cracks were then monitored. This chapter teaches Carlos’s and Janelle’s part of the story: what to notice, how to record it and when to call.

                8.2Learning objectives#

                1. Trace a load path from roof to soil and say what each element does.
                2. Name the common structural systems found in schools and commercial buildings.
                3. Describe the warning signs of settlement, overload, corrosion, moisture and fire damage.
                4. Record cracks and movement so that an engineer can use the record.
                5. Know the line between observation and engineering judgment.
                6. Escalate correctly and follow up.

                8.3Why the subject matters#

                • Structure is the one system you cannot afford to lose. A failed pump can be replaced. A failed beam can hurt people.
                • Most structural trouble gives warning. Cracks, sticking doors, sagging, rust stains and water are early signals if someone notices and writes them down.
                • The cause is often water. Roof, drainage and plumbing leaks cause or speed up many structural problems.
                • Alterations change loads. Heavy equipment, new roof layers, removed walls and stored materials can overload a structure that was fine before.
                • Records matter. A dated photograph with a scale is worth more to an engineer than a description from memory.

                8.4Plain-English technical explanation#

                The load path

                Every load, from snow and wind to students and equipment, must travel to the ground through a continuous chain: roof covering and deck, joists or trusses, beams, columns or bearing walls, foundations, soil. If any link is weakened, loads shift to its neighbors. Cracks and deflection show where the chain is strained.

                Common structural systems

                SystemWhere you see itHow it fails or shows distress
                Masonry bearing wallsOlder schools, small commercialStair-step cracks along mortar joints, bulging walls, loose or spalled brick, corroding lintels
                Reinforced concrete frame and slabsLarger and newer buildingsRust stains, concrete spalling over rebar, wide or offset cracks, deflection of slabs
                Steel frameGyms, warehouses, mid-riseCorrosion at bases and connections, bent or buckled members, loose bolts, water ponding at roof framing
                Wood framing and heavy timberHouses, older schools, light commercialRot, termite damage, sagging joists, notched or cut members, moisture at bearing points
                Pre-engineered metal buildingsWarehouses, industrial, gymsLoose or missing bracing, damaged frames, roof leaks at fasteners, added loads from hung equipment
                Slab-on-grade and foundationsNearly all buildingsSettlement, heave, cracking, uneven floors, doors and windows that stick, water at the footing

                Why cracks happen

                Cracks are the building’s way of showing strain. Five broad causes cover most of what you will see: shrinkage and temperature (usually harmless, common in new concrete), settlement or heave (soil movement), overload (too much weight or removed support), corrosion and moisture (rusting reinforcement, rotting wood) and lateral pressure (soil or water pushing on a wall). The pattern, width, location and whether the crack is changing help an engineer tell them apart. You cannot tell reliably from a photograph, so record and escalate.

                What to record

                1. Location: room, wall, grid line, height above floor.
                2. A photo with a scale (ruler or crack card) and a wide view for context.
                3. Crack length, direction and width at its widest point.
                4. Date, time, weather in the last few days, and who observed.
                5. Pencil marks at the crack ends with dates, or a crack gauge fixed across it.
                6. Associated signs: sticking doors, gaps at windows, sloping floors, water.

                8.6How to decide whether a requirement applies#

                1. Is there any sign of imminent danger? Sudden movement, new loud cracking, sagging, collapse of any part. Clear the area, call for help and follow Chapter 4.
                2. Is it structural or cosmetic? If you cannot tell, treat it as structural until an engineer says otherwise.
                3. Is the crack or movement changing? Monitor with dated marks or a gauge. Growth means escalate.
                4. Is a repair or alteration planned? Permits and the adopted code probably apply. Ask the building official.
                5. Could the work disturb asbestos, lead or other regulated materials? Check the plan before any cutting or demolition.
                6. Who is allowed to decide? Engineering judgment belongs to a licensed engineer.

                8.7Building systems, components and terminology#

                Load path

                The chain of elements that carry weight from the roof to the ground.

                Dead load / live load

                Dead load is the building’s own weight. Live load is people, furniture, equipment and stored items. Snow and wind are separate.

                Footing

                The wide base under a wall or column that spreads load into soil.

                Slab-on-grade

                A concrete floor poured directly on prepared ground.

                Settlement

                Downward movement of a foundation as soil compresses. Differential settlement, where one part moves more than another, causes cracks.

                Heave

                Upward movement, often from swelling clay soils or frost.

                Deflection

                Sagging of a beam, joist or slab under load.

                Spalling

                Flaking or breaking away of concrete surface, often from corroding rebar.

                Efflorescence

                White salty deposit left when water moves through masonry or concrete. A sign of moisture.

                Shoring

                Temporary support installed to carry load. Designed by an engineer.

                8.8Step-by-step inspection demonstration#

                Fictional facility
                Marsh Landing Elementary, built in two phases (1962 and 1996). Janelle walks the exterior and the affected wing. She uses a phone camera, a tape and a crack comparator card. She does not touch, cut or load anything.
                Demonstration A: Reading a diagonal crack at a door frame
                Looking for
                The crack’s direction, length and width, whether it continues through finishes, and whether it is accompanied by other signs.
                Why it matters
                Diagonal cracks at openings can indicate differential movement. They can also be minor. Only an engineer can say which.
                Documents to review
                As-built drawings, foundation type, past repair records, geotechnical report if any, drainage and plumbing leak history.
                Check visually
                Both sides of the wall, adjacent rooms, the exterior at the same location, the ground and downspouts outside, floor level with a straightedge or a level, door and window gaps.
                Instruments or specialists
                Crack comparator card, tape, level, a camera. For diagnosis: licensed structural engineer, and a geotechnical engineer if soil is suspected.
                Potential deficiency
                Possible differential settlement; drainage discharging at foundation; no monitoring in place.
                Location and evidence
                Room 114, east wall, grid line C; photos with scale; pencil marks with dates; measured width and length.
                Immediate risk
                No sign of sudden movement. Treat as Medium to High pending the engineer. Escalate to Critical if movement is sudden, cracks open quickly or any member sags or shifts.
                Who is notified
                Principal; structural engineer; superintendent.
                Prioritize and verify
                Engineer visit within days. Drainage correction can start immediately because it is low-risk. Verify by continued crack monitoring.
                Records to keep
                Photos, measurements, monitoring log, engineer’s report, repair record.
                Demonstration B: Rust stains and spalling on a concrete canopy
                Looking for
                Rust-colored stains, flaking concrete, exposed reinforcement and water paths.
                Why it matters
                Corroding reinforcement swells and breaks concrete. It reduces strength, and falling pieces can injure people.
                Documents to review
                Original drawings, past repairs, any condition survey, entry-use records.
                Check visually
                From the ground, with binoculars if needed. Do not stand under loose concrete. Look at drainage, joints and the underside.
                Instruments or specialists
                An engineer, who may sound the concrete or test for corrosion.
                Potential deficiency
                Spalling with exposed reinforcement over an entrance.
                Location and evidence
                Main entrance canopy, north edge. Photos from several angles.
                Immediate risk
                Falling concrete is a hazard to people below. Barricade the area under it now.
                Who is notified
                Principal; engineer; risk manager.
                Prioritize and verify
                High because of the falling-object hazard. Verify the barricade daily until repairs are done.
                Records to keep
                Photos, barricade log, engineer’s report, repair record.

                8.9Annotated visual and tools#

                Figure 8.1Load path and where distress shows up
                Original schematic, not to scale and not any particular building. Numbers match the list below the drawing. What to learn Distress appears where the chain of load or the water control fails. Notice the pattern and its location, then record and escalate.
                  Exercise 8.1Match the observation to the likely cause family

                  Choose the cause family that best fits each fictional observation. Real diagnosis needs an engineer. The point is to learn the vocabulary and the habit of recording.

                  Tool 8.1Crack monitoring log

                  Enter dated width readings from a crack gauge or comparator card. The tool computes change since the first reading and flags growth larger than the measurement uncertainty. The uncertainty value is a teaching assumption. An engineer sets the real criteria.

                  8.11Realistic case study: The Sticking Door#

                  Fictional case
                  Pine Hollow Middle School and the people in it are invented. The case is a composite of patterns, not a record of a real event.

                  What happened. Over a summer, a wing at Pine Hollow Middle School developed sticking doors and a few hairline diagonal cracks. Staff planed the doors and filled the cracks with patching compound. In the fall, the cracks reappeared wider and a window frame began to gap. Only then did the principal call the district.

                  What the engineer found. A leaking underground water line had saturated soil under part of the foundation, and a downspout had also been discharging next to the wall. The soil had softened and the footing had settled unevenly. The structure was not in imminent danger, but if left, movement would have continued.

                  What was done. The leak was repaired, the downspout was extended away from the building, the soil was allowed to stabilize while the cracks were monitored, and the engineer designed a limited repair.

                  What went wrong. Cosmetic fixes hid the message. Nobody recorded the first cracks or measured them, so the engineer had no history.

                  Lessons. (1) Do not paint over movement. Record it first. (2) Check water sources at any crack. (3) Monitor, because a stable crack and a growing crack call for different responses.

                  Use the Chapter 4 scale with these structural adjustments:

                  • Critical (override): any sign of imminent failure or sudden movement; a falling-object hazard over a walkway or entrance; collapse of any part. Clear the area now.
                  • High: cracks that are wide, offset, growing or accompanied by sticking doors; sagging that is getting worse; corrosion with section loss; any alteration that removed or cut structure without engineering.
                  • Medium: stable cracks of unknown cause awaiting evaluation; drainage problems near foundations; wood decay that has not yet affected members.
                  • Low: hairline shrinkage cracks documented as stable by an engineer or by monitoring.

                  Corrective-action planning. Record, make safe, notify, engage an engineer, remove the cause where you can safely do so (water first), monitor, and close only on the engineer’s written finding or a monitoring record that shows stability.

                  8.14Common mistakes and professional lessons#

                  • Patching the crack and forgetting it. Record and monitor first, then repair on advice.
                  • Shaving the door. A sticking door is a message about movement.
                  • Guessing the cause from a photo. Escalate with a record and let an engineer decide.
                  • Ignoring water. Roof, drainage and plumbing leaks drive many structural problems.
                  • Adding load without checking. Roof equipment, storage racks and new roof layers need engineering.
                  • Cutting or removing members to run services. Never without an engineer.

                    Remember
                    • Loads follow a chain to the ground. Distress shows where the chain or the water control is failing.
                    • Record cracks with photos, a scale, dated marks and measurements.
                    • Watch for sticking doors, sagging, rust stains, spalling and water.
                    • Escalate growth. Clear the area for any sign of imminent failure.
                    • Only a licensed engineer diagnoses and designs repairs.
                    • Fix water problems first, and never cut structure without engineering.

                    Building Envelope, Roofs, Windows, Doors and Drainage

                    Water is patient. How do you keep it out, and how do you trace it when it gets in?

                    Chapter 9 of 20

                    Safety boundary for this chapter
                    Roofs are fall hazards. Do not walk a roof, lean over an edge or step near a skylight without a written access plan, the right fall protection and a second person. The default for this book is to inspect from the ground and from the interior, and to use a qualified roofing contractor for the roof itself. Never test a skylight or a ceiling by stepping or pressing on it. Wet, icy, windy or stormy conditions are never a reason to go up.

                    9.1Opening scenario#

                    Fictional scenario · Bayou Pines Elementary and its people are invented

                    The first heavy rain of fall brought a wet ceiling tile in the library and a dripping sound in the hallway outside it. The custodian, Reggie, put a bucket under the drip, wrote “leak, library” on the whiteboard and went back to work. The bucket was empty by lunch. The leak, everyone assumed, was over.

                    Three weeks later, a second storm brought it back, with a new stain two ceiling tiles over. The facility manager, Tomasz, asked a simple question: where was the water coming from? Looking at the ceiling would not tell him, because water travels. He checked, in order: the roof above, the nearest roof drain, the flashing at a rooftop unit curb, the wall that met the roof at that corner, and the window head outside the library.

                    It was the flashing at the curb, three meters from the stain. A quick sealant fix had been applied years earlier, and it had cracked. Tomasz did not go on the roof. He took photographs from the second-floor window, wrote a scope and had the roofing contractor make the repair with a safe-access plan.

                    This chapter is about reading water, protecting the layers that keep it out, and doing it without anyone falling.

                    9.2Learning objectives#

                    1. Name the layers of a roof and a wall that control water, air and heat.
                    2. Describe common roof types and their typical failure points.
                    3. Trace a leak from the stain back to its likely source.
                    4. Inspect windows, doors, sealants and drainage from safe positions.
                    5. Plan a roof access decision using the fall-protection rules in this book.
                    6. Write a repair scope that a contractor can price and a manager can verify.

                    9.3Why the subject matters#

                    • Water is the most common cause of building damage. It rots wood, rusts steel, grows mold, ruins ceilings and equipment and weakens structure (Chapter 8).
                    • Roofs are expensive and short on warning. A small leak can mean wet insulation across a large area.
                    • Envelope problems drive energy and comfort complaints. Drafts, condensation and hot rooms often start at the envelope.
                    • Roof work is dangerous. Falls are a leading cause of serious injury in construction and maintenance.
                    • Small, cheap maintenance prevents big repairs. Clearing drains and resealing a joint cost far less than replacing a roof early.

                    9.4Plain-English technical explanation#

                    The four control layers

                    A building envelope controls water, air, heat and vapor. Each job is done by a layer or a set of layers, and the weak points are where layers meet: edges, corners, openings and penetrations.

                    LayerJobTypical materialsWhere it fails
                    Cladding or roof coveringFirst defense against rain and sunBrick, metal, siding, membrane, shinglesCracks, open joints, aging, punctures
                    Drainage plane and flashingShed water that gets past the cladding and direct it outHousewrap, felt, metal flashing, sealed membranesMissing or reversed flashing, laps in the wrong order, sealant used in place of flashing
                    Air barrierStop air leaking through the envelopeSealed membrane, taped sheathingGaps at penetrations, joints and transitions
                    InsulationSlow heat flowRigid, batt, spray foamWet, compressed or missing insulation
                    Vapor controlManage moisture moving by diffusionMembranes, coatingsWrong location in the assembly for the climate

                    Roof types you will meet

                    TypeDescriptionCommon problems
                    Low-slope membrane (single-ply, built-up, modified bitumen)Nearly flat roofs on schools and commercial buildingsPonding, seam failure, punctures, flashing at curbs and parapets, blocked drains
                    Metal roofingStanding-seam or panel systemsFastener back-out, sealant failure, corrosion at cut edges, loose panels
                    Steep-slope shingle or tilePitched roofsMissing or lifted shingles, damaged ridge, flashing leaks at chimneys and valleys
                    Green or ballasted roofsRock or vegetation over a membraneHidden leaks, clogged drains, added weight
                    Field note
                    Water travels. A stain on a ceiling is where the water came out, not necessarily where it got in. Trace uphill and along the framing, and look at every interruption in the envelope above the stain: drains, curbs, pipes, walls, windows.

                    Windows, doors and sealants

                    Windows and doors are openings in the envelope. Check the head, jamb and sill for flashing and sealant, the glazing seals for fogging, the weatherstripping for gaps and the thresholds for drainage and corrosion. Sealant is a maintenance item: it ages, hardens and loses adhesion. A joint with a crack, gap or loose edge needs replacing. Sealant is not a substitute for flashing.

                    Drainage

                    Roofs need working drains, scuppers and gutters, with overflow paths. Grade at the building should slope away. Downspouts should discharge well away from foundations. Blocked drains cause ponding, overloading and leaks. They are the cheapest thing to maintain and the most often neglected.

                    9.6How to decide whether a requirement applies#

                    1. Does anyone need to go on the roof? If the question can be answered from the ground, a window, a lift or drone photographs by a qualified operator, do that.
                    2. Is a fall hazard present? Edges 4 feet or more above a lower level, skylights, openings, ladders. Assume yes.
                    3. Who may go? A trained person with the right equipment, a written plan and a partner. Otherwise a qualified roofer.
                    4. Will the work disturb roofing materials in an older building? Check the asbestos plan first.
                    5. Is a permit needed for the repair? Ask the building official.
                    6. Does the warranty or insurer require a specific contractor?

                    9.8Step-by-step inspection demonstration#

                    Fictional facility
                    Bayou Pines Elementary. Tomasz works from the ground, the interior and an open second-floor window. No one goes on the roof during this demonstration. Roof access is planned with the roofer and the safety officer.
                    Demonstration A: Tracing a ceiling leak without climbing
                    Looking for
                    The path from stain to source, and what has changed since the last dry spell.
                    Why it matters
                    Fixing the stain does not fix the leak. Wet insulation and rotted framing can hide above it.
                    Documents to review
                    Leak history, roof drawings, warranty, past repairs, roofing consultant reports, rain and storm dates.
                    Check visually
                    Stain shape and age (rings mean repeated wetting), above-ceiling space from a safe access point, the wall and window outside at that corner, downspouts and ground drainage, roof edges and rooftop equipment from a window or a lift.
                    Instruments or specialists
                    A moisture meter and an infrared camera operated by a trained person; the roofing contractor for roof-level investigation.
                    Potential deficiency
                    Cracked flashing at a curb, blocked drain, failed seam, sealant used as a patch, wall or window leak.
                    Location and evidence
                    Library northwest corner; photographs of stain, curb from the window and the drain; moisture readings.
                    Immediate risk
                    Water near electrical equipment, a sagging ceiling or visible mold raises priority. Keep people out from under a sagging ceiling.
                    Who is notified
                    Principal; roofing contractor; the safety officer for roof access.
                    Prioritize and verify
                    Medium to High. Temporary protection now, repair by qualified contractor, verify after the next rain with a dry-ceiling check and moisture reading.
                    Records to keep
                    Leak log, photographs, readings, repair scope and completion record.
                    Demonstration B: Windows, doors and sealants from the ground and inside
                    Looking for
                    Cracked or missing sealant, failed glazing seals, damaged weatherstripping, water staining below openings and blocked weep holes.
                    Why it matters
                    Water enters at the edges of openings, and failed seals waste energy.
                    Documents to review
                    Window schedule, warranty, past sealant replacement, door hardware records.
                    Check visually
                    Sealant at head, jamb and sill; fogging between panes; gaps at weatherstripping; staining on the interior sill; threshold condition and drainage.
                    Instruments or specialists
                    A flashlight and a moisture meter. A window specialist for failed glazing.
                    Potential deficiency
                    Failed sealant, fogged units, missing weatherstripping, rotted sill, blocked weep holes.
                    Location and evidence
                    West elevation, windows W-3 to W-9; photographs and a defect list.
                    Immediate risk
                    Low unless water reaches electrical equipment or damages structure. Egress doors must keep working: check hardware and thresholds.
                    Who is notified
                    Maintenance supervisor; principal for classroom impact.
                    Prioritize and verify
                    Plan reseal on a schedule. Verify by inspection after rain.
                    Records to keep
                    Defect list, photographs, contractor scope and completion record.

                      9.11Realistic case study: The Painted Skylight#

                      Fictional case
                      Harlan Ridge Middle School and the people in it are invented. The case is a composite of patterns, not a record of a real event.

                      What happened. A maintenance technician went on the roof of Harlan Ridge Middle School to check a rooftop unit that had tripped. He had been on the roof several times and trusted the path he knew. A re-roofing project the previous summer had left a dome skylight in a new spot, painted over by the roofer to match the membrane. He stepped within a foot of it before he noticed the curb, and stopped.

                      What came next. Nobody was hurt. The technician reported the near miss. The district found there was no roof-access plan, no marked safe path, no guardrail around the skylight and no fall protection in the maintenance shop.

                      What changed. The district stopped routine roof access by maintenance staff, hired a roofing contractor for inspections twice a year and after storms, added guards to skylights and wrote an access plan that required fall protection and a second person.

                      Lessons. (1) A near miss is a free lesson. Record it. (2) Familiar roofs change. (3) The safest way to inspect a roof is often not to be on it.

                      9.13Risk classification and corrective actions#

                      • Critical (override): sagging ceiling or roof; water around live electrical equipment; unguarded skylight or roof opening where people can reach it; egress doors that no longer open.
                      • High: active leaks over occupied rooms; ponding with signs of overloading; wet insulation spreading; fogged or broken glazing that creates a hazard.
                      • Medium: sealant failure, minor flashing defects, blocked drains without active leaks, drafts.
                      • Low: cosmetic weathering and isolated minor staining that has dried and not recurred.

                      Corrective-action planning. Make people and equipment safe, stop the water, notify, scope the repair with the contractor, plan safe access, verify after the next rain and record the closure date. Schedule drain clearing, sealant replacement and roof inspections so that they stop being emergencies.

                      9.14Common mistakes and professional lessons#

                      • Fixing the stain. Replace the tile after the leak is found and fixed.
                      • Using sealant instead of flashing. Sealant ages and often hides the real problem.
                      • Walking the roof “just to look.” Use the ground, a window, a lift or a qualified contractor.
                      • Ignoring drains. The cheapest maintenance prevents the costliest leaks.
                      • Skipping the asbestos check. Old roofing and flashing can contain it.
                      • Not verifying after rain. A repair is proven by the next storm.

                        9.17Key takeaways#

                        Remember
                        • Layers control water, air, heat and vapor. Leaks start at the joins between layers.
                        • A stain shows where water came out, not where it got in. Trace uphill and look at every interruption above it.
                        • Inspect from the ground, the inside and a window first. Use qualified contractors for the roof.
                        • Edges and skylights 4 feet or more above a lower level need protection under OSHA 1910.28 (verified for covered employers).
                        • Drains, sealants and flashing are maintenance, not emergencies.
                        • Verify repairs after the next rain.

                        HVAC, Ventilation, Filtration, Refrigeration and Controls

                        Most complaints about a building are really complaints about air. How do you work out what the air system is doing, and where to stop?

                        Chapter 10 of 20

                        Safety boundary for this chapter
                        Observe, measure from safe positions, and call qualified technicians. Do not open electrical disconnects or panels, remove fan guards or belt covers on running equipment, handle refrigerant or open refrigerant circuits, bypass safety controls or work on gas-fired equipment. Refrigerant work requires an EPA-certified technician. Never go on a roof without the access plan in Chapter 9. If you smell gas, leave the area and call the utility and emergency services.

                        10.1Opening scenario#

                        Fictional scenario · Willow Run Middle School and its people are invented

                        In September, three teachers at Willow Run Middle School separately reported the same thing: “the kids are drowsy by third period.” Room 207 was hot. Room 209, next door, was cold. The principal wanted the thermostats lowered. The HVAC contractor suggested a larger unit.

                        Facility manager Imani Okafor asked a smaller question: what does the air actually look like in these rooms? She borrowed a CO2 meter from the district office. At the end of third period, Room 207 read well above the outdoor reading. She looked at the rooftop unit schedule on the control screen. The outdoor-air damper was set to its minimum position and the unit was running on a schedule that started only fifteen minutes before school. A filter bank was nearly black.

                        The fix was not a bigger unit. It was a filter change, a corrected damper setting and a schedule that began earlier. The hot and cold rooms turned out to be a stuck damper actuator and a thermostat on the wrong wall.

                        This chapter teaches how to read an air system from the outside, so that the right specialist is called for the right reason.

                        10.2Learning objectives#

                        1. Describe the path of air through a typical air-handling system and the job of each component.
                        2. Explain what ventilation, filtration, heating, cooling and controls each do.
                        3. Describe the refrigeration cycle in plain language and the legal limits on refrigerant handling.
                        4. Estimate ventilation per person from a carbon dioxide reading and state the limits of the method.
                        5. Diagnose common comfort complaints in the right order.
                        6. Know when to call a technician, an air-balance specialist or an engineer.

                        10.3Why the subject matters#

                        • HVAC is usually the largest energy user and the largest source of complaints.
                        • Air quality affects people. Ventilation, filtration and humidity influence comfort and how people feel and perform.
                        • Failures are expensive and seasonal. Chillers and boilers fail on the hottest and coldest days (Chapter 2).
                        • Refrigerants are regulated. Handling them without certification is a legal problem and an environmental one.
                        • Controls hide problems. A system on a wrong schedule or with a stuck damper can waste energy for years without a single breakdown.

                        10.4Plain-English technical explanation#

                        The air path

                        Most buildings move air through the same sequence: outdoor air and return air mix; the mixture passes through a filter; a coil heats or cools it; a fan pushes it through ducts to supply diffusers in rooms; return air goes back through grilles and ducts; some air is exhausted and replaced with outdoor air. Figure 10.1 shows the path with six places to check.

                        What each function does

                        FunctionWhat it doesTypical componentsTypical failure
                        VentilationBrings in outdoor air and removes stale airOutdoor-air damper, exhaust fans, energy-recovery unitsDamper stuck or set to minimum, blocked intakes, exhaust off
                        FiltrationRemoves particles from the airFilter banks (graded by a MERV rating)Loaded filters, bypass around filters, wrong grade for the unit
                        HeatingAdds heatBoilers and hot-water coils, furnaces, electric heaters, heat pumpsScale, controls, burner problems (gas work is for qualified technicians)
                        CoolingRemoves heat and moistureChillers, direct-expansion (DX) units, cooling towers, coilsLow airflow, dirty coils, low refrigerant, compressor faults
                        DistributionMoves air to roomsFans, ducts, dampers, diffusers, VAV boxesStuck dampers, leaking or disconnected ducts, imbalance
                        ControlsDecide when and how muchThermostats, sensors, building automation system (BAS), schedules, setpointsWrong schedule or setpoint, failed sensors, overrides left on

                        The refrigeration cycle, briefly

                        Cooling equipment moves heat from inside to outside using a refrigerant that changes between liquid and gas. A compressor pressurizes the refrigerant gas. In the condenser it gives up heat and becomes a liquid. A metering device drops its pressure. In the evaporator coil it absorbs heat from the air passing over it and becomes a gas again. The cycle repeats. Anything that cuts airflow (dirty filter, dirty coil, failed fan) or changes the charge changes how well this works.

                        Limit
                        Refrigerant charge, pressures and electrical measurements are for certified technicians. A facility manager can see the symptoms, such as ice on the coil, oily residue at fittings, short cycling, warm supply air, and report them with accurate records.

                        Ventilation and a carbon dioxide reading

                        People breathe out carbon dioxide (CO2). In an occupied room, the indoor CO2 reading above the outdoor reading is a rough indicator of how much outdoor air each person is getting. It is not a measure of air pollutants and it does not replace a ventilation measurement. It is useful for a quick screen, with a calibrated meter, after the room has been occupied long enough for the reading to settle. Tool 10.1 uses the steady-state idea.

                        Humidity and filtration

                        Too humid air feeds mold and feels clammy. Very dry air is uncomfortable. Filters are graded with a MERV number from 1 to 16: a higher number catches smaller particles but resists airflow more. A unit designed for one grade may not move enough air through a denser filter. Ask the manufacturer or an HVAC technician before changing grade.

                        10.5Applicable laws, codes, standards and official references#

                        10.6How to decide whether a requirement applies#

                        1. Is there a risk to people right now? Gas smell, carbon monoxide alarm, smoke, flooding, loss of heat in extreme cold. Evacuate or protect people, then call. Follow Chapter 4.
                        2. Does the work involve refrigerant? Only certified technicians. Venting is prohibited.
                        3. Is it a boiler or a pressure vessel? State inspection rules and a qualified technician.
                        4. Is it a change to the system (new equipment, new ductwork, new capacity)? Codes, permits and an engineer probably apply.
                        5. Is it ventilation or air quality? Find out which code or standard is adopted and what the design basis was.
                        6. Otherwise follow manufacturer instructions and the strategy chosen in Chapter 2.

                          10.11Realistic case study: The Schedule Nobody Changed#

                          Fictional case
                          Mill Creek Elementary and the people in it are invented. The case is a composite of patterns, not a record of a real event.

                          What happened. Mill Creek Elementary had a year of complaints about warm classrooms in the afternoon and a high electric bill. The district considered adding another rooftop unit. A technician reviewed the building automation schedule instead and found that during a summer renovation someone had set all units to run in an “occupied” mode around the clock and had left the outdoor-air dampers fully open. In humid weather the system was cooling and drying large volumes of outdoor air all night.

                          What it cost. The units were wearing out faster and humidity control was poor. The extra unit would have cost many times the schedule fix.

                          What was done. The schedule and damper settings were corrected, filters changed, a test-and-balance specialist adjusted airflows and the district began recording BAS changes with a reason and a name.

                          Lessons. (1) Check controls before buying equipment. (2) Log changes to schedules and setpoints. (3) A complaint about comfort is a request for investigation, not a request for a bigger unit.

                          10.13Risk classification and corrective actions#

                          • Critical (override): gas odor, carbon monoxide alarm, combustion fumes or smoke; loss of heat during dangerous cold when people cannot be kept safe; flooding near live electrical equipment. Evacuate or protect people, call the utility, emergency services or qualified help.
                          • High: overdue boiler or pressure-vessel inspection; blocked combustion air; refrigerant leak signs; large areas with no ventilation; recurring equipment trips.
                          • Medium: comfort complaints with a clear cause, loaded filters, wrong schedules, minor control faults.
                          • Low: cosmetic issues, noise without a trend, minor insulation damage.

                          Corrective-action planning. Check controls and filters first because they are cheap and common. Use a qualified technician for equipment and any refrigerant. Measure before and after. Record changes to schedules, setpoints and overrides.

                          10.14Common mistakes and professional lessons#

                          • Buying equipment before checking controls. Schedules and dampers cause many “capacity” complaints.
                          • Using higher-grade filters without checking the unit. Too much resistance cuts airflow.
                          • Closing outdoor-air dampers to save energy. This can shortchange ventilation.
                          • Leaving overrides on. Review them weekly.
                          • Letting a non-certified person handle refrigerant. It is illegal in many cases and unsafe.
                          • Treating CO2 as a pass-fail air test. It is a screen, not proof of air quality.

                            10.17Key takeaways#

                            Remember
                            • Follow the air: controls, dampers, filters, coil, fan, ducts, room.
                            • Check cheap, common causes first: filters, schedules, dampers, thermostats.
                            • A CO2 reading is a screen for ventilation, not a measure of air quality.
                            • Refrigerant work is for certified technicians. Venting is prohibited.
                            • Gas smell, CO alarm or smoke: evacuate and call.
                            • Log control changes with a reason and a name.
