Chapter 23 Quiz — Quality Management

22 questions. Answer before opening each <details> block. Scoring guide at the end.


Multiple Choice (10)

Q1. A superintendent walks a completed wall with a checklist and records the results. This activity is:

A. Quality assurance B. Quality control C. A special inspection D. A pre-installation conference

Answer

B. Quality control — it verifies work that already exists. Quality assurance is the system that prevents defects before the work happens: the approved submittal, the mockup, the pre-installation conference, the sequence. A checklist applied to a finished wall is a measurement, not a control.


Q2. Under the definition used in this chapter, "quality" on a construction project means:

A. Work performed to the highest standard the crew is capable of B. Work that will not generate warranty callbacks C. Conformance to the contract documents D. Work the architect is satisfied with

Answer

C. Conformance to the contract documents. Answer D is a trap that contains a partial truth: where the documents say "to the satisfaction of the Architect," satisfaction is the standard for that item — but only because the contract documents say so. The general definition is conformance, and it cuts both ways: work better than specified is still nonconforming, and a specification that is wrong is a design issue with a change-order remedy, not a quality issue.


Q3. You have notified the required party of a witness point and nobody comes. You should:

A. Stop work until they arrive B. Proceed with the work and document that notification was given C. Have your own QC person sign in their place D. Ask the architect to waive the requirement in writing

Answer

B. Proceed and document. That is precisely what distinguishes a witness point from a hold point: the notification is the obligation, not the attendance. Your notification record — sent with the required lead time, in writing, to the right party — is what protects you afterward. C is falsification. D is unnecessary and creates a document implying the requirement was mandatory.


Q4. A hold point on your inspection and test plan may be waived by:

A. The superintendent, if the schedule requires it B. The project manager, with documentation C. Only the party that holds it, in writing D. Nobody, ever, under any circumstances

Answer

C. The party that holds it, in writing. A hold point is somebody's right to see the work before it is covered; only that somebody can give it up, and only on paper. D is close but wrong in a way that matters — hold points are released all day long, by the right person, with a signature. The failure mode is not release; it is release by the wrong person, or by nobody at all.


Q5. The disposition "use as is" requires, at minimum:

A. The contractor's QC manager's approval B. The subcontractor's written agreement to extend the warranty C. The design professional's written acceptance D. A note in the daily report

Answer

C. The design professional's written acceptance — and the owner's as well wherever value, appearance, maintainability, or warranty is affected, usually accompanied by a credit. Accepting a deviation is a professional judgment about whether the building still works. It belongs to the person whose license covers that judgment, never to the superintendent, the PM, or a verbal "it's fine."


Q6. The primary difference between a mockup and a benchmark installation is:

A. A mockup is required by the specification; a benchmark is voluntary B. A mockup establishes the standard before production; a benchmark is the first real installation, accepted and used as the standard thereafter C. A mockup is for appearance; a benchmark is for performance D. A mockup is built by the subcontractor; a benchmark is built by the general contractor

Answer

B. The mockup resolves the design; the benchmark proves the production. They are not substitutes. Northgate had a mockup and no benchmark, and 28 openings of storefront went in before anybody compared the second build to the first — a $97,684 lesson.


Q7. The single most common root cause of rework in the chapter's Northgate data was:

A. Damage to completed work B. Out-of-sequence work C. Unclear or conflicting contract documents D. The installer never saw the approved submittal

Answer

D. Nine of Kestrel's 31 nonconformance reports. It is also the cheapest to fix: one added column in the submittal log — issued to installer, date, signed by — plus a rule that no scope starts until the cell is filled.


Q8. A missed special inspection is dangerous primarily because:

A. It voids the contractor's insurance B. The building official may require destructive verification, since the inspector cannot report on work they did not observe C. It automatically triggers liquidated damages D. The architect can reject the entire assembly

Answer

B. The final report of special inspections is generally required before a certificate of occupancy is issued, and an inspector cannot certify what they did not see. There is often no paperwork remedy — the paths are an engineering evaluation from as-built records, nondestructive or destructive verification, or removal and replacement.


Q9. Which of these is not a punch item?

A. A scratch in a finished door B. A misaligned reveal at a storefront head C. A ceiling grid that has not been installed D. A paint holiday on a corridor wall

Answer

C. An uninstalled ceiling grid is incomplete work, not a punch item. That distinction is the one that decides substantial-completion arguments: punch items are complete-but-nonconforming and generally do not prevent beneficial use; incomplete work can. Keep the two on separate lists.


Q10. In the cost-of-quality model, money spent on mockups and pre-installation conferences belongs in which bucket?

A. Prevention B. Appraisal C. Internal failure D. External failure

Answer

A. Prevention. Appraisal is money spent finding out whether defects occurred — inspection, testing, surveys. On Northgate, prevention plus appraisal was $482,000 and failure was $846,000. The leverage is in moving money into prevention, not into more appraisal.


True / False (6)

For each, answer and give a one-line justification.

Q11. An approved submittal that deviates from the specification makes the deviation conforming.

Answer

False. A submittal is the contractor's representation of how it will satisfy the contract documents; approval does not amend them. Only a change order, a construction change directive, or a documented accepted substitution changes a requirement.


Q12. The architect's periodic field observation is a form of inspection that the contractor may rely on to catch nonconforming work.

Answer

False. Most design agreements state the architect will make periodic visits to become generally familiar with progress and quality and will not be required to make exhaustive or continuous inspections. The architect is not your safety net — Dale Whitcomb found the storefront because he happened to look up.


Q13. Lab-cured cylinders are the correct basis for deciding when to strip formwork.

Answer

False. Lab-cured cylinders are the acceptance test for the concrete as a material, cured under standard conditions. Stripping and reshore removal are governed by the in-place strength criterion in the contract documents, verified by field-cured cylinders (cured alongside the element) or an approved alternative such as the maturity method — and released by the authority the contract names, never the foreman.


Q14. Because a punch list is generated at the end of a project, the punch process cannot begin until the building is substantially complete.

Answer

False, and the chapter argues this is the single most expensive habit in closeout. The well-run project punches continuously, by area, at each handoff between trades — while the crew that made the item is still in the building and before the next layer of work covers it.


Q15. If a general contractor engages the testing laboratory rather than the owner, the test results are less reliable.

Answer

False as to reliability — a reputable lab performs identically either way. What changes is the appearance of independence, and appearance is what you end up arguing about when a result is unfavorable. The practical response for a contractor-engaged lab is to distribute every report, including failures, the same day it arrives.


Q16. Concealing known nonconforming work is a contract problem of the same kind as any other defect.

Answer

False, and this is the most important false statement on this quiz. Nonconforming work that is disclosed and dispositioned is a managed contract event. Work that is knowingly concealed can pull in fraud and misrepresentation theories, which in many jurisdictions carry longer limitation periods, potential punitive exposure, and coverage questions with your insurer — plus licensing-board consequences. The concealment, not the defect, changes the category of the problem.


Short Answer (4)

Q17. Explain, in three or four sentences, why the crew that will perform the work must attend the mockup review. Use a mechanism, not a slogan.

Answer

A mockup review is an agreement reached by people standing in front of a physical object. If the installers are absent, that agreement must travel to them through four lossy handoffs — the subcontractor's PM, marked-up shop drawings, a phone call, and a foreman's memory of the phone call — and the things that get lost are exactly what a mockup is good at communicating: sequence, feel, how hard to press a roller, which way a lap runs, how tight a reveal must look. Text is interpreted by every reader in the chain; a physical benchmark collapses all those interpretations into one object everyone has touched. It relocates disagreement from the field, where it costs a hundred thousand dollars, to a bench, where it costs an afternoon.


Q18. Give the four dispositions for nonconforming work, and for each name the approver.

Answer
  1. Rework — bring to full conformance. Approver: contractor's QC plus the identifying party on re-inspection.
  2. Repair — bring to an acceptable non-specified condition by an engineered method. Approver: the design professional in writing (the engineer of record where structure or life safety is involved); often the owner as well.
  3. Use as is — accept as installed. Approver: the design professional in writing, plus the owner where value, appearance, maintainability, or warranty is affected. Usually carries a credit.
  4. Reject and replace — remove and reinstall. Approver: contractor's QC plus the identifying party; the design professional confirms the replacement conforms.

Q19. A 28-day cylinder break returns 8% below the specified strength. Name three things you check before concluding the concrete is bad.

Answer
  1. The test itself — casting, initial curing, transport, and capping; whether the cylinders were lab-cured or field-cured (field-cured routinely break lower and are not the acceptance test); the technician's certification.
  2. The batch ticket and placement record — mix identification, batch-to-discharge time, whether water was added at the site and by whose authorization, and the fresh-property results at discharge.
  3. The specification's acceptance criteria — structural concrete acceptance is generally statistical, based on averages of consecutive tests with a limit on how far any single test may fall below the specified strength. One low cylinder may not even constitute a failing test.

Only after those three does the structural question arise — cores, evaluation, and a judgment that belongs to the engineer of record, not to you and not to the lab.


Q20. Why does a punch list delay final payment, structurally?

Answer

Because final payment typically requires final completion, final completion requires the punch list to be complete, and retention release is generally tied to it. The punch list is therefore the last gate in front of several hundred thousand dollars of the contractor's money — on Northgate, the 5% retention still being held after 50% completion — and every additional week it stays open is a week that money finances somebody else's business.


Applied Scenarios (2)

Q21. You discover that 340 LF of an air barrier transition has been installed with 1½-inch laps where the approved submittal requires 3 inches, and with reversed shingle order at four locations. The installer says it will perform fine. Drywall closes the run in four days.

State (a) whether this is a nonconformance and on what basis, (b) the two things you do in the first fifteen minutes, and (c) why the installer's performance opinion is irrelevant to your classification decision.

Answer

(a) Yes. The basis is documentary, not technical: the installed condition does not match the approved submittal (sheet 3, detail 2), which reflects the manufacturer's written instructions, which the specification incorporates by reference. Any one of those three is sufficient. The reversed shingle order at four locations is a defect in kind, not just in degree — an upward-facing lap in a barrier that must shed incidental water.

(b) First fifteen minutes: (1) Stop the cover — call the drywall superintendent and follow with an email holding gypsum board on that run. (2) Bound the extent — send inspectors to check the same condition on every other level, 100%, today, because you cannot disposition a nonconformance whose size you do not know. (Photographing with a tape in frame is a close third.)

(c) Because "it will perform fine" is a disposition argument, not a classification argument. Classification asks only whether the work matches the requirement. Disposition asks what to do about it — and that judgment belongs to the design professional and, on a warranted system, the manufacturer, not to the installer at the work face. Keeping those two decisions separate, and in different hands, is the entire discipline of nonconformance management.


Q22. Three days before a scheduled certificate of occupancy, the fire marshal lifts a ceiling tile and finds an unfirestopped head-of-wall joint in a rated smoke barrier. Investigation shows 2,140 LF affected, in nobody's subcontract: the firestop subcontractor priced penetrations, the drywall subcontractor excluded firestopping by others. Both scope sheets are accurate.

State (a) where and when this failure was actually born, (b) the single ITP line that would have caught it, and (c) why the same defect costs roughly seven times more in month 19 than in month 11.

Answer

(a) At the buyout scope comparison in month five, not in the field. Two accurate scope sheets described a boundary that neither one crossed, and the person comparing them read for what each said rather than for what neither said. Scope gaps live between subcontracts, and the general contractor owns that space.

(b) A close-in release hold point before ceiling installation: rated partitions — head-of-wall joint installed and inspected per the listed assembly — release to install ceiling grid. Kestrel had exactly that line for the exterior wall assembly and it worked; there was no equivalent for interior rated partitions.

(c) Because the cost of correcting a defect is a function of how much finished work sits between you and it. The firestopping itself is about $31,000 either way. The other roughly $199,000 is access: thousands of ceiling tiles lifted and reset, night work around move-in, 62 cuts through finished hard ceilings, patching and repainting, lead-lined gypsum replacement, radio-frequency shielding repair and re-verification, and re-cleaning. The work did not get more expensive. Reaching it did.
