Multiple Choice (11)
1. A buyout log shows a package awarded $114,000 below the estimate. During scope review you learn the subcontractor excluded $107,000 of specified work that no other package carries. The correct entry on your variance report is:
A. $114,000 favorable B. $7,000 favorable C. $107,000 unfavorable D. Gross $114,000 favorable, net $7,000 favorable, with the $107,000 shown as a scope-gap funding line
Answer
D. Report gross and net separately, always, and show what moved between them. A single number invites the reader to believe the wrong one. Answer B is arithmetically right but hides the size of the miss, which is the information a reader actually needs in order to ask whether there are more of them.
2. The main reason to use a subcontract rather than a purchase order is that:
A. Subcontracts are longer documents B. The vendor's employees will perform work on your site, so you need safety, insurance, indemnity, schedule, and lien-waiver obligations C. Purchase orders cannot exceed $100,000 D. Purchase orders are not enforceable
Answer
B. The practical test is whether the vendor's employee sets foot on your job to perform work. A PO for goods carries none of the site obligations you need from anyone working on your project. There is no dollar threshold rule, and POs are certainly enforceable.
3. In the Northgate steel story, the date that actually controlled the outcome was:
A. Kestrel's April 15 approval milestone B. Caldwell Structural's 14-day review period C. Ironbridge's April 18 release-to-mill deadline D. The August 4 erection start
Answer
C. April 18 was the fabricator's real production constraint, and it lived on the fabricator's schedule rather than on any Kestrel document. Kestrel managed its own milestone (April 15) and never asked for the one that mattered. Ask every long-lead subcontractor: what is your no-later-than release date, and what happens if we miss it?
4. An EMR of 0.92 tells you that the contractor's:
A. Recordable injury rate is 8% below the industry average B. Workers' compensation loss experience is 8% better than expected for a company of that size and class in that state C. Safety program has been audited and approved D. Crews have not had a lost-time injury in three years
Answer
B. EMR is a workers' compensation premium multiplier built from claim cost history relative to expected losses for that class, size, and state. It is not a recordable rate, not an audit result, and not a statement about the current crew. It is also backward-looking, volatile for small firms, and jurisdictional.
5. A pay-if-paid clause differs from a pay-when-paid clause in that pay-if-paid:
A. Sets a shorter payment period B. Applies only on public work C. Makes owner payment a condition precedent, shifting owner-credit risk to the subcontractor D. Is unenforceable in all fifty states
Answer
C. Pay-when-paid is a timing clause; pay-if-paid is a condition precedent. Enforceability varies significantly by state — some enforce clearly drafted clauses, some refuse on public-policy grounds, some require unmistakably explicit language, and some limit the clause by statute or by its interaction with prompt-payment, lien, or payment-bond rights. Verify governing law for your specific project; never carry one state's rule into another.
6. The scope-gap hunt on Northgate surfaced $389,000 of scope across three adjacent trades, but only $291,000 was genuinely unbought. The other $98,000 was:
A. An estimating error B. Scope already carried in another subcontractor's base bid — that is, scope Kestrel was about to buy twice C. Owner-furnished material D. Work deleted by value engineering
Answer
B. Half the value of a seam walk is finding double-buys. If you hunt only for gaps you will add the access panels to the drywall subcontract while the mechanical subcontractor is already carrying them, and pay for the same 186 panels twice.
7. Which of these is clarifying scope rather than bid shopping?
A. "You need to be under $2.4 million to be competitive." B. "Somebody is $118,000 below you." C. "Your proposal excludes head-of-wall firestop, which the package requires. Send me a revised number that includes it." D. "Match the low number and the job is yours."
Answer
C. It identifies specific scope, discloses no competitor's price, and asks for a corrected number rather than a lower one. And if the discovered gap changes the package, the disciplined move is to reissue to all bidders — which is the one rule that makes shopping structurally impossible.
8. Nearly every equipment manufacturer's standard terms disclaim consequential damages and cap liability at the purchase price. The practical consequence for a project manager is:
A. Negotiate liquidated damages into every material purchase order B. Buy from domestic suppliers only C. You cannot buy schedule protection from a supplier; you can only buy it with float D. Use a subcontract instead of a PO for all equipment
Answer
C. If the switchgear is ten weeks late, your remedy is very likely repair or replacement and nothing more. Time spent negotiating delay damages into a material PO is time you should have spent moving the order three weeks earlier.
9. Flow-down (incorporation by reference) in a subcontract:
A. Gives the subcontractor all of your rights against the owner B. Binds the subcontractor to the obligations you owe the owner, as to the subcontractor's work C. Makes the owner liable directly to the subcontractor D. Replaces the need for a scope exhibit
Answer
B. Flow-down transfers obligations, not benefits. If you want the subcontractor to have your rights — a time extension, for example — you must say so. And you must actually make the prime contract available to them; flowing down terms nobody was shown is both unfair and frequently unenforceable.
10. Your prime contract gives you 21 days from an event to notice the owner. Your subcontracts should give subcontractors:
A. The same 21 days, for consistency B. 30 days, to be fair to the subcontractor C. A meaningfully shorter period — 7 days is common — so you have time to evaluate and pass the claim through D. No notice requirement, since you have one
Answer
C. This is the "notice sandwich." A subcontractor who notices you on day 21 leaves you zero days to notice the owner. Check your subcontract's notice period against your prime contract's on every job — copying last job's subcontract onto a project with a 10-day owner notice period builds a trap.
11. Subcontractor default insurance (SDI) differs from subcontractor bonds primarily in that with SDI:
A. There is no cost B. The general contractor becomes the underwriter and carries a self-insured retention on every loss C. Public owners always prefer it D. Coverage is unlimited
Answer
B. SDI is first-party insurance the contractor buys. The carrier requires an approved prequalification program because you are now evaluating subcontractor credit. It is usually cheaper and faster to respond, and it lets capable firms that cannot get bonded onto your jobs — but the retention is real money on every event, and many public statutes and owner contracts require bonds regardless.
True / False (5)
Give a one-line justification for each.
12. A green (favorable) buyout variance is always good news for the project.
Answer
False. A favorable variance caused by unbought scope is a deferred loss. Northgate's week-three $312,000 of "savings" contained $196,000 of scope nobody had bought — and one of the three headline savings was actually a $7,000 overrun.
13. More bid packages always reduce your risk, because more competition produces lower prices.
Answer
False. More packages produce more competition and more seams. Every additional package is another boundary at which two proposals can each say "by others." The right number of packages is driven by how many qualified bidders each will attract, not by how the specification is filed.
14. A scope gap discovered in the field costs roughly the same as one discovered at buyout, because the work itself is identical.
Answer
False. The Northgate blocking gap was $107,000 at buyout and roughly $279,450 in month nine — about 2.6 times — because of demolition, re-close, refinish, and markup. And the multiplier is not the worst part: at buyout you have five bidders and no signed contract; in month nine you have one mobilized subcontractor and no alternative.
15. Caldwell Structural caused the Northgate steel delay by taking fourteen days to review the anchor bolt submittal.
Answer
False. Caldwell used exactly its contractual review period, as planned. The entire slip came from Kestrel holding the submittal eleven days instead of five — and, more fundamentally, from a back-schedule with zero float that tracked the approval date rather than the fabricator's release date.
16. Because a subcontract exists, you can always backcharge a subcontractor for work that falls in a gap between their scope and the adjacent trade's.
Answer
False. A backcharge requires a contractual obligation the subcontractor failed to perform. You cannot backcharge someone for work they never agreed to do. On Rivermont Elementary, Curtis Boone's backcharges against Delacroix and Vessel both failed on exactly that ground — and would have failed a second time on the 48-hour written notice precondition he had already blown.
Short Answer (4)
17. Explain, in terms of bidder incentives, why the bidding process systematically produces scope gaps.
Answer
Three linked mechanisms. (1) The specification is filed by product and system, not by responsibility, so nothing in it assigns the work between two systems. (2) The low bidder wins, so a bidder facing ambiguous scope must choose between including it and being higher, or excluding it and being lower — over enough bids the market selects for exclusion. (3) Exclusion pages are boilerplate that travels from job to job, and "by others" means "not by me" while saying nothing about who others is.
The result is a system that reliably produces holes in which every hole is technically disclosed. The scope sheet is the only instrument that closes them, because it is the only document written from the boundary's point of view.
18. Name the four control points from the Northgate steel failure and state, for each, roughly what it would have cost to implement in March.
Answer
(1) Ten days of procurement float, bought by issuing a letter of intent at GMP approval instead of waiting for the executed subcontract — cost: one page and a signature. (2) A gating-submittal list with a 48-hour internal clock and a named owner — cost: a one-page list and a daily two-minute standup. (3) Tracking the fabricator's release-to-mill date, not the approval date — cost: one question, asked once. (4) Pre-negotiated expedited review (7 days instead of 14) for the four gating submittals — cost: a conversation at the design-team kickoff, possibly a small design-assist fee.
Each one alone would have prevented all twenty-three days and the $168,000 of acceleration.
19. A subcontractor's proposal excludes "in-wall blocking by others." Explain why the phrase "by others" is more dangerous than a phrase like "by the structural steel erector," and describe the discipline that neutralizes it.
Answer
"By others" names no one. It tells you only that this bidder does not have the work — and every competing bidder's boilerplate says the same thing, so the exclusion cancels out in a vertical bid comparison and never appears as a price difference. A named exclusion at least gives you a party to check with.
The discipline is the horizontal seam walk: put adjacent packages' proposals side by side and, for each of the twenty seam-checklist items, force a yes or no and name the package that carries it. Then trace each item back into every base bid to catch scope you are about to buy twice.
20. Why is the required-on-site date for a large piece of electrical switchgear sometimes set by a physical constraint rather than by the construction schedule? Give the Northgate example.
Answer
Because oversized equipment must be rigged into its room before the building is closed around it. Northgate's 3,000-amp switchgear enters the level-1 main electrical room through the north loading opening, which closes when architectural precast panel P-C4 is set on February 10, Year 2 — long before the equipment is needed electrically.
Missing that window does not delay the electrical system; it costs $18,500 to leave a panel off and heat the room, $31,000 to remove and reset the panel, or $52,000 to cut a slab opening and rig from above. Buying the switchgear three weeks earlier costs $0.
Applied Scenario (2)
21. You are 60 days into a $31,000,000 job. Your buyout log shows 24 of 31 packages awarded, gross variance $418,000 favorable. Reviewing three adjacent proposals — site utilities, plumbing, and fire protection — you find that the site utility contractor's scope stops five feet outside the building line, the plumber's scope is defined by four drawing numbers that stop at the building line, and the fire protection contractor starts at the riser flange. The fire service main, a grease waste line and interceptor, and 620 LF of yard storm piping are on the drawings.
(a) State what you have found and roughly what it is worth if the pattern matches Rivermont Elementary. (b) State what you do in the next 48 hours, in order. (c) State what you report, and to whom, and what you do with the gross variance number.
Answer
(a) You have found a classic boundary gap of the type that cost Curtis Boone $180,000 on a $22.4M job — the fire main, the grease waste system including the interceptor, the yard storm piping, and almost certainly the foundation sleeves, coring, and re-compaction in the five-foot zone. On a $31M job, budget in the same order of magnitude and do not assume you have found all of it.
(b) In order: (1) Do not issue any of the three subcontracts if any are unexecuted — stop them today. (2) Take off the actual quantities so you are negotiating with numbers, not adjectives. (3) Run the full twenty-item seam checklist across all three pairs, not just the items you noticed, and also trace back for double-buys. (4) Call all three subcontractors for scope review, separately, and ask each to state who they believe has each item. (5) If a package is unexecuted and the scope changes materially, reissue to all bidders rather than negotiating with one. (6) Write the boundary language — physical location, everything assigned on both sides, plus the order-of-precedence clarification that makes the scope exhibit govern over the attached proposal.
(c) Report both numbers to your operations executive the same week: gross $418,000 favorable, and net after funding the identified gaps. Show the gap as its own line with a description, not netted invisibly. Book a named scope-gap reserve inside contingency for the seams you have not yet walked, with a date to retire it. On a cost-reimbursable or GMP contract, tell the owner's representative too — on a 75/25 savings split, most of the money at stake is theirs.
22. A curtain wall fabricator gives you these durations: submittal preparation 35 CD, your review 5 CD, A/E review 14 CD, resubmittal 12 CD, second review 10 CD, extrusion and glass lead time 42 CD, fabrication 45 CD, transit 8 CD. First panels are required on site November 20, Year 1.
(a) Compute the latest subcontract execution date assuming one review round. (b) Compute it assuming two rounds. (c) State which date you manage to, and give the reason in one sentence. (d) Name the single stamp on a submittal that is worth 22 days, and the conversation you would have in March to make it more likely.
Answer
(a) Nov 20 − 8 = ships Nov 12 → −45 = fabrication starts Sep 28 → −42 = material ordered/released Aug 17 → −14 = to A/E Aug 3 → −5 = fabricator submits Jul 29 → −35 = subcontract executed no later than June 24, Year 1.
(b) Add 22 CD (12 resubmittal + 10 second review): June 2, Year 1.
(c) June 2. On a delegated-design curtain wall reviewed by an architect and a structural engineer, the two-round cycle is the base case, not the risk case — build it into the plan and treat first-round approval as recovered float.
(d) "Approved as noted" — which permits fabrication to proceed — versus "revise and resubmit," which does not. In March, at the design-team kickoff, identify the gating submittals by name and ask the A/E to use "approved as noted" wherever their comments do not go to design intent. It is a free conversation and it is worth three weeks.
