Appendix G — Contract Clause Decoder: The 25 Clauses That Decide Who Pays

Read this before anything else

This appendix is not legal advice, and it cannot be.

I am a project manager, not a lawyer. Construction law is not one law — in the United States alone it is fifty-plus bodies of state law, plus federal law, plus local ordinance, plus whatever your contract says, and this book is read in countries whose systems differ from all of that. Pay-if-paid enforceability, no-damage-for-delay enforceability, retention caps, prompt-payment periods, anti-indemnity statutes, lien deadlines, and the test for whether liquidated damages are a valid pre-estimate or an unenforceable penalty all vary substantially by jurisdiction and change over time. A rule that is true in one state is malpractice in the state next door.

So here is what this appendix is for. It is a spotting guide. Holding a contract you have never seen, you can find any of these clauses, understand what it does to you, and know what to ask. Recognizing the issue early enough that counsel can still help you is the entire skill. A construction lawyer called on day 4 can save a claim. The same lawyer called on day 40 is writing you a sympathy card with an invoice attached.

Two ground rules:

• I do not quote contract language. Not from the AIA family, not from ConsensusDocs, not from EJCDC, not from FIDIC, not from any owner's form. I describe what such clauses typically do. Your contract's actual words are the only ones that govern you, and the standard forms get edited on every project. Read yours.
• I do not cite clause numbers, statute sections, or cases. Anyone who quotes a general-conditions article number to you from memory is telling you which form they last read, not what your contract says.

The dollar figures throughout are Northgate's, because you already know them:

G.1 How to read a contract you have never seen before, in ninety minutes

You will be handed contracts you did not negotiate. A subcontract on somebody else's form. A prime agreement your business development group signed while you were on another job. A 190-page general conditions document with a 40-page supplement attached, three days before the bid.

You cannot read all of it well in ninety minutes. You can read the parts that decide arguments.

The mindset: you are not reading for comprehension. You are reading for deviation from the standard. The published forms are broadly known; what will hurt you is where somebody moved something. So you are hunting for edits.

That last row is the one people skip and the one that pays. The general conditions are a known quantity. The supplementary conditions are twelve to forty pages of specific, deliberate edits by somebody paid to protect the owner, and they are where a no-damage-for-delay clause quietly appears, where the differing site conditions clause quietly disappears, and where a mutual waiver of consequential damages quietly becomes one-directional.

🏗️ From the field. I once read a set of supplementary conditions on a Friday afternoon and found a single added sentence stating that the contractor's sole remedy for any delay, from any cause, was an extension of time. Eleven words. On a job with a $4,100/CD general-conditions burn, a plausible 25-day owner-caused delay was $102,500 that we would never see. We priced it, told the owner why our number moved, and the owner — who had not personally read its own lawyer's edit — took the sentence back out. Nobody had put it there to cheat us. Somebody had put it there because it was in the last set.

Ninety minutes is not a substitute for your attorney reading the document, and on anything that consumes a meaningful share of your bonding capacity, your attorney reads it. What the ninety minutes buys is that you walk into that conversation with the four questions you actually need answered.

G.2 The twenty-five clauses at a glance

G.3 The clauses, one at a time

Clause 1 — Scope of work and the order of precedence of the contract documents

Also called: contract documents; intent; interpretation; correlation of documents; conflicts; precedence; complementary documents.

What it does, in plain English. It lists exactly which papers make up your contract, and it says what happens when two of them disagree — which they will, hundreds of times in a large set. It also usually imposes a duty on you to study the documents, compare them, and promptly report errors you find.

Who it favors. Whoever drafted it. A "most stringent requirement governs" clause is the most one-sided version in common use, because it means you priced the cheap reading of every ambiguity and owe the expensive one.

What to look for. Which of three regimes you are in — complementary with no hierarchy (you cannot self-help; you must ask), stated hierarchy (a ranked list you can cite), or most stringent governs. Whether specifications govern drawings or the reverse. Whether the duty to report errors carries a consequence — the standard structure is that a discrepancy you should have found and did not report becomes yours. And whether anything is "reasonably inferable," which on an incomplete GMP set is a very large phrase.

The question to ask before you sign. "If Section 03 30 00 says a five-inch slab and sheet S-101 shows four inches, which one am I contractually obligated to build, and who makes that call?"

What it costs you if you get it wrong. One inch of slab across Northgate's 33,000 SF slab on grade is 102 CY of additional concrete — roughly $18,870 at $185/CY placed, before you touch the cascade into door thresholds, MEP sleeves, and finish floor elevations. The clause costs nothing to read and decides who pays that. See Chapter 7.

Clause 2 — Changes clause (and the construction change directive)

Also called: changes in the work; modifications; change orders; directed changes; unilateral change order; construction change directive (CCD); field order; force account.

What it does, in plain English. It gives the owner the right to change the work without renegotiating the whole contract, and it sets the method by which price and time get adjusted. The directive half lets the owner order you to proceed before the price is agreed, so a disagreement about money does not stop the job.

Who it favors. The owner — it is the owner's power to compel. But a contractor with no changes clause is worse off, because then a change is a new negotiation with the crew standing down.

What to look for. Which pricing methods the clause allows: negotiated lump sum, agreed unit prices, cost plus a stated percentage, or owner-determined. The markup schedule and, more importantly, the base each percentage applies to — that is where the real negotiation lives, not in the rate. Whether time must be claimed with the price or is a separate submission on a separate clock. Whether the contract says no work will be paid for without a prior written order, which is the language that makes a constructive change argument hard.

The question to ask before you sign. "If you direct me to proceed before we agree on a price, what exactly may I bill while I build it, and what records do you require from me daily?"

What it costs you if you get it wrong. Change order #14 on Northgate. Verbal go-ahead on a Thursday, concrete on Monday, no written directive and no time-and-material tickets for four days. Kestrel incurred $186,400, substantiated $121,000, settled at $142,750, and ate $43,650 — which is more than the $12,741 of contract markup the change actually earned. The change made no profit and lost hard cost. See Chapter 31.

Clause 3 — Differing site conditions (Type I and Type II)

Also called: changed conditions; concealed or unknown conditions; subsurface and physical conditions; DSC.

What it does, in plain English. It decides who pays when the ground, or a concealed condition in an existing building, is not what the documents led you to expect. Type I is a condition materially different from what the contract documents indicated. Type II is an unknown physical condition of an unusual nature, differing materially from what is ordinarily encountered in work of that character.

Who it favors. The contractor, when it is present. Delete it and the risk is yours, priced or not.

What to look for. First, whether it survived the supplementary conditions. Second, whether the geotechnical report is a contract document or is furnished "for information only" with a disclaimer of reliance — that single distinction can hollow out a Type I claim. Third, the notice window, which is often much shorter than other notice periods; some public contracts require notice within 48 hours. Fourth, whether you must stop work and give the owner an opportunity to inspect before disturbing the condition. Disturb it first and you have destroyed your own evidence.

The question to ask before you sign. "Is the geotechnical report a contract document, and if it is not, what am I entitled to rely on?"

What it costs you if you get it wrong. Northgate's three differing-site-conditions change orders totaled $238,000 and 5 calendar days on a job with a good clause and 14 borings. Delete the clause and add language that the contractor has satisfied itself as to all site conditions, and bids on a job with real subsurface uncertainty typically rise by one to three percent of contract value — on Northgate, $475,000 to $1,425,000 of contingency the owner pays whether or not the condition ever appears.

Clause 4 — Delay and time extension

Also called: extensions of time; excusable delay; force majeure; adjustment of the contract time; unavoidable delays.

What it does, in plain English. It sorts delays into three buckets and says what each one earns you. The grid every project manager should be able to draw on a napkin:

Who it favors. Neutral when well drafted. It becomes an owner clause the moment a no-damage-for-delay sentence is added (Clause 5) or the weather baseline is written unrealistically.

What to look for. The normal-weather assumption — how many adverse days per month are already inside the contract time, and against what record they are measured. Whether a time extension requires a time impact analysis run on the current accepted schedule update. Whether concurrent delay bars compensation entirely, or only bars it for the concurrent period. Whether the clause defines what counts as force majeure or leaves it to argument.

The question to ask before you sign. "How many adverse weather days per month are included in the contract time, and whose weather record settles it?"

What it costs you if you get it wrong. The Northgate steel delay ran 23 calendar days on the critical path: 23 CD × $10,650/CD = $244,950. That number is what a delay clause is arguing about. See Chapter 33.

Clause 5 — No-damage-for-delay

Also called: extension of time as sole remedy; delay damages waiver; sole and exclusive remedy for delay. It very often has no heading at all — it is one sentence inside the delay clause or the supplementary conditions.

What it does, in plain English. It says that if you are delayed — even by the owner — your only remedy is more days. No extended general conditions, no unabsorbed home-office overhead, no compensation of any kind. Just time.

Who it favors. The owner, more than any other clause in this appendix. This is the single clause that most changes your risk profile, and it is frequently the shortest one in the document.

What to look for. Read the delay clause, the suspension clause, and the supplementary conditions together, because the sentence may live in any of them and it modifies all three. Look for carve-outs — many jurisdictions recognize exceptions for the owner's active interference or bad faith, for delay not within the contemplation of the parties, for abandonment, and for fraud. Do not rely on the exceptions; they are litigated, which means they cost money and sometimes lose. Also check whether the clause is limited to delays under a stated duration, which is the most common negotiated compromise.

The question to ask before you sign. "If the owner delays me thirty days, do I get paid my extended general conditions — yes or no — and show me the sentence that says so."

What it costs you if you get it wrong. A 30-calendar-day owner-caused delay on Northgate:

Same delay, same fault, $154,500 of difference, decided by one paragraph. On Willow Street the same thirty days is 30 × $1,600 = $48,000.

⚖️ Jurisdiction. Enforceability, the recognized exceptions, and statutory limits — several states restrict or prohibit the clause, particularly on public work — vary significantly by state and change over time. Price it, negotiate it out, or walk. Do not assume a court will save you.

Clause 6 — Liquidated damages

Also called: LDs; stipulated damages; delay damages; per-diem damages.

What it does, in plain English. It fixes, in advance, a daily dollar amount you owe for each day of unexcused delay past substantial completion, so nobody has to prove actual damages later. Northgate's is $5,500 per calendar day.

Who it favors. The owner — but the version that is the owner's exclusive remedy protects you, because it caps an otherwise open-ended exposure at a known number.

What to look for. Whether the amount traces to a reasonable pre-estimate of the owner's actual loss made at the time of contracting, rather than operating as a punishment; a provision that is a penalty rather than an estimate is unenforceable in most U.S. jurisdictions, and the specific test varies by state. Whether LDs are the exclusive remedy, or whether the owner may claim LDs and actual damages. Whether there is a corresponding time-extension mechanism — an LD clause with no way to earn an extension is a trap, and courts in many jurisdictions will not enforce LDs against a contractor the owner itself delayed. Whether milestone LDs stack on top of completion LDs. Whether there is a cap.

The question to ask before you sign. "Are these liquidated damages the owner's exclusive remedy for late completion, and is there an aggregate cap?"

What it costs you if you get it wrong. Meridian's build-up, which is what a defensible LD rate looks like:

Twenty-three days late is $126,500 in LDs alone, before your own $5,150/CD of extended general conditions.

Clause 7 — Notice and claim requirements

Also called: claims procedure; notice of claim; time limitation on claims; conditions precedent to recovery.

What it does, in plain English. It requires you to give written notice of a condition or a claim within a short, specified period — commonly 7, 10, 14, or 21 days — and it usually says that failure to give timely notice waives the claim entirely. Many clauses start the clock not when you noticed the problem but when you knew or should have known of it, which can start it before anyone on your team was thinking about a claim.

Who it favors. The owner, overwhelmingly. This clause voids more valid claims than any other clause in construction. Real condition, clear entitlement, proven damages — and you lose because you gave notice on day 22.

What to look for. Different clocks for different claim types. Northgate's one-page notice sheet has five entries — changed conditions, owner-directed change, delay, claim for additional cost, and claim for additional time — with different clocks on three of them, and a competent project manager losing a valid claim to the wrong clock is the most common way this clause bites. Then: the trigger language (event vs. discovery vs. knew or should have known), the addressee named in the contract, the required delivery method (an email may not satisfy a certified-mail requirement), the required content, and whether a claim must be certified.

The question to ask before you sign. "Which of these deadlines runs from the event and which runs from when we knew or should have known — and exactly who must receive the notice, by what delivery method?"

What it costs you if you get it wrong. Everything. A claim worth $244,950 and a claim worth zero are the same claim, twenty-four hours apart. Notice costs ten minutes and a stamp. Write it politely, write it every time, and withdraw it if the issue evaporates — nobody has ever been damaged by a politely worded notice.

Clause 8 — Payment terms and prompt payment

Also called: applications for payment; progress payments; payment procedure; certification.

What it does, in plain English. It sets when you may apply for payment, how long the owner or its architect has to certify, how long the owner then has to pay, and what the owner may withhold. Northgate: apply by the 25th, owner pays in 30 days.

Who it favors. The owner as drafted; statutes push back. Every day of the cycle is working capital you are financing.

What to look for. The real elapsed time from the first day of the work period to the day the money lands — Northgate's 25th-and-30 structure means work performed on the 1st is paid for roughly 55 days later, and that is a good set of terms. Every condition precedent to payment: lien waivers, lower-tier waivers, certified payroll, an accepted schedule update, as-built markups, safety documentation. A stack of conditions turns a 30-day term into a 60-day term without changing a number. The owner's list of permitted withholding reasons and whether it is exclusive. Whether interest accrues on late payment.

The question to ask before you sign. "What is the longest time that may lawfully pass between the day I pay a subcontractor for work in place and the day the owner pays me for that same work?"

What it costs you if you get it wrong. Thirty extra days of float on a $2,500,000 monthly billing, at an 8% cost of capital: $2,500,000 × 0.08 × 30 ÷ 365 = $16,438 per month, every month, for the life of the job.

⚖️ Jurisdiction. Prompt-payment statutes exist in most U.S. states and vary widely in coverage, timing, interest rates, and whether they apply to private work, public work, or both. Federal and state public contracts often carry their own regimes. Verify yours; do not carry one state's rule across a state line.

Clause 9 — Retention and its release

Also called: retainage; holdback; withholding of a percentage of payment.

What it does, in plain English. The owner keeps a percentage of every progress payment as security until you finish. Northgate: 10% until the job is 50% complete, then 5%. You do the same to your subcontractors, and it is their profit being held.

Who it favors. The owner. It is a pure cash-flow cost to you, and it is the last money you see.

What to look for. Whether the reduction at 50% is automatic or discretionary — "may be reduced in the owner's sole discretion" is not a reduction. Whether retention is released at substantial completion or held to final completion, which on Northgate is sixty days later. Whether the owner may instead retain a multiple of the punch-list value (150% and 200% are both common) — usually a much better deal for you. Whether release requires closeout documents you cannot control, such as a consultant's certification. And whether your subcontract flows retention down at the same rate, so a subcontractor who finished in month four does not wait fourteen months for its money.

The question to ask before you sign. "At substantial completion, exactly what is released, exactly what may still be held, and on what schedule?"

What it costs you if you get it wrong. Willow Street: $6,800,000 × 5% = $340,000 held. Carried at a 9% cost of capital for an average of eight months, that is $20,400 of pure financing cost with no offsetting revenue.

⚖️ Jurisdiction. Retention limits, permissible percentages, reduction triggers, release timing, and substitution of securities are set by statute in many states, differ between public and private work, and change. Check yours before you rely on any number in this book.

Clause 10 — Pay-if-paid versus pay-when-paid

Also called: condition precedent to payment; contingent payment clause; payment contingency.

What it does, in plain English. These two phrases look like synonyms and are not. Pay-when-paid is a timing clause: the contractor pays the subcontractor a reasonable time after being paid, and if the owner never pays, the contractor generally still owes the subcontractor eventually. Pay-if-paid is a condition precedent: the subcontractor is paid only if the contractor is paid, and the subcontractor bears the risk of the owner's insolvency, permanently.

Who it favors. The contractor, against the subcontractor. It moves owner-credit risk onto a party with no relationship to the owner, no ability to evaluate the owner's finances, and no ability to price the risk.

What to look for. The exact words. Enforceable pay-if-paid language in the jurisdictions that permit it is usually unmistakable — it uses the phrase condition precedent and states that the subcontractor assumes the risk of the owner's nonpayment. Anything softer is likely a timing clause. Also check whether the clause is carved back where nonpayment results from the contractor's own default (it should be), and whether it purports to defeat payment-bond or lien rights.

The question to ask before you sign. "If the owner becomes insolvent and never pays for work my crew has already installed, does this clause mean I never get paid?"

What it costs you if you get it wrong. Sightline Interiors billed $284,000 for one month of drywall work on Northgate — $269,800 net after 5% retention. Under an enforceable pay-if-paid clause, an owner default in May makes that month permanently gone, along with every dollar of retention held behind it. A subcontractor who signs one without understanding it has quietly become the owner's lender.

⚖️ Jurisdiction. Enforceability varies significantly by state. Some states enforce clearly drafted pay-if-paid clauses as written; some refuse to enforce them at all as against public policy; some enforce them only where the condition-precedent language is unmistakably explicit; some limit them by statute; and in some, prompt-payment statutes, lien rights, or payment-bond claims make the clause far weaker than it reads. Several states have changed position in the last two decades. Do not carry one state's answer into another, and do not carry this book's summary into any state.

Clause 11 — Schedule submission, acceptance, and float ownership

Also called: progress schedule; construction schedule requirements; CPM specification; scheduling and reporting.

What it does, in plain English. It tells you what schedule to submit, in what software and format, how often to update it, what the owner's review means — and, critically, who owns float. Float is the project's shared time contingency, and this clause assigns it.

Who it favors. Whoever the float sentence names. Most clauses say float is a project resource available to either party on a first-come basis, which in practice means the owner can consume your buffer with changes at no cost.

What to look for. The float ownership sentence — and whether it addresses early completion. If your baseline shows completion forty days ahead of the contract date and the owner then delays you twenty days, whether you can claim that delay turns entirely on this clause and on how the baseline was accepted. Whether "acceptance" of the baseline means the owner approved the logic or merely received the file. Whether failure to submit an acceptable schedule allows the owner to withhold payment — common, and painful. Whether a specified scheduling package and specific calculation settings are required.

The question to ask before you sign. "Who owns float on this project, and if I submit a baseline showing completion forty days ahead of the contract date, does this contract recognize that time as mine?"

What it costs you if you get it wrong. A 6-calendar-day slip on an activity carrying 9 days of float is worth $0 — it consumed float and drove nothing. The identical 6-day slip on a zero-float path is worth 6 × $10,650 = $63,900. The difference exists in exactly one place: the total-float column of a schedule update somebody had to run at the time. See Chapter 14.

Clause 12 — Suspension of work

Also called: stop work order; owner's right to suspend; suspension for convenience.

What it does, in plain English. It lets the owner halt the work temporarily without terminating the contract, and it says what — if anything — the owner owes you for the stoppage.

Who it favors. The owner. But suspension is normally compensable, which makes this one of the better clauses in an owner's contract from your side.

What to look for. Whether suspension is compensable and by what measure — a contract that pays the agreed extended general-conditions daily rate is clean; one that requires you to prove delay damages is an argument waiting to happen. Whether a no-damage-for-delay clause overrides it, which is the single most important interaction in this appendix: a compensable suspension clause plus a no-damage-for-delay clause may leave you with time and nothing else. Whether there is a maximum suspension duration after which you may terminate and be paid as on a termination for convenience. Whether demobilization and remobilization costs are recoverable. Whether suspension for your own default is expressly non-compensable (it will be).

The question to ask before you sign. "If you suspend the work for sixty days, what do you pay me, and at what point may I terminate?"

What it costs you if you get it wrong. Sixty calendar days of suspension on Northgate is 60 × $5,150 = $309,000 of extended general conditions, plus remobilization, plus resequencing. If a no-damage-for-delay clause governs, the same sixty days pays $0.

Clause 13 — Termination for convenience versus termination for cause

Also called: termination for convenience / for the owner's convenience; termination for default; termination by the owner for cause; suspension and termination.

What it does, in plain English. Two very different clauses that live next to each other. For convenience: the owner may end the contract for any reason or none, and pays you for work performed plus, usually, demobilization and reasonable closeout — but typically not lost profit on the work you never got to build. For cause: the owner ends the contract because you defaulted, and you may owe the cost to complete above the remaining contract balance, with your surety involved.

Who it favors. The owner, both times.

What to look for. The notice-and-cure period before a termination for cause — its length and what counts as a cure — because that is your only real protection. Whether a termination for cause later found to be wrongful converts automatically into a termination for convenience; that single sentence is worth negotiating hard for, because without it a wrongful termination becomes a lawsuit instead of a payment. What termination for convenience actually pays: work in place, materials ordered, demobilization, subcontractor termination costs, fee on work performed — and whether "reasonable termination costs" is defined or left open. Whether the owner may take assignment of your subcontracts.

The question to ask before you sign. "If I am terminated for cause and it is later found the termination was wrongful, does this contract convert it to a termination for convenience?"

What it costs you if you get it wrong. Northgate terminated for convenience at 40% complete: you have earned roughly 40% of the $1,804,800 fee and forgo about $1,082,880 of fee you planned on and staffed for. Termination for cause is worse by an order of magnitude — the surety pays the owner, then comes after you under the general indemnity agreement you signed to get bonded. See Chapter 5.

Clause 14 — Indemnity

Also called: indemnification; hold harmless; defend, indemnify and hold harmless; indemnity and defense.

What it does, in plain English. One party promises to protect another from claims — to defend the lawsuit, pay the judgment, and cover the costs. In construction it is how liability for jobsite injuries flows uphill from subcontractor to contractor to owner. Three forms:

Who it favors. The indemnitee, always — which means it favors whoever is above you in the chain, and it favors you against your subcontractors.

What to look for. How far up the fault scale it reaches. Whether the duty to defend is separate from the duty to indemnify — a defense obligation starts immediately, before anyone knows who was at fault, and defense costs can exceed the eventual judgment. Whether the obligation is capped by available insurance limits or is unlimited and lands on your balance sheet. And whether your insurance actually funds what you promised, which is the question most companies cannot answer.

The question to ask before you sign. "Does our insurance program actually fund the indemnity obligations in this contract?" — put it to your broker and your attorney in the same meeting.

What it costs you if you get it wrong. An ironworker is injured on Northgate; investigation puts 60% of the fault on Kestrel's uncovered floor opening and 40% on the subcontractor. Under an enforceable intermediate-form indemnity, the subcontractor owes Kestrel a defense and indemnity for the whole claim. In a strict anti-indemnity state, the same clause is cut back to 40% or void as written. Same facts, same words, materially different results.

⚖️ Jurisdiction. Anti-indemnity statutes vary enormously. Some void only broad form. Some void intermediate form too. Some extend the prohibition to additional-insured coverage that achieves what the statute just outlawed. Some carve out exceptions for owners, public agencies, or project types. There is no shortcut.

Clause 15 — Insurance requirements, additional insured status, and waiver of subrogation

Also called: insurance; contractor's liability insurance; property insurance; builder's risk.

What it does, in plain English. It sets the policies and limits every party must carry, who must be named as an insured on whose policy, and who gives up the right to sue whom after an insurer pays. It is the funding mechanism behind the indemnity clause — indemnity says who owes, insurance says whose money pays.

Who it favors. Whoever gets named. Read it as the party being protected and as the party paying, because you are usually both.

What to look for. That additional-insured status is granted by endorsement to the policy, not by a sentence in the description box of a certificate. That you get both the ongoing-operations and the completed-operations endorsements, which are frequently separate forms. Primary and non-contributory language, without which two carriers argue for months about who defends. A per-project aggregate, without which the sub's annual limit is shared with every other job it is on. Waiver of subrogation on general liability and on workers' compensation. Who buys builder's risk, who is named on it, and who pays the deductible. How long completed-operations coverage must be maintained after final completion.

The question to ask before you sign. "Send me the actual additional-insured endorsement forms — ongoing and completed operations — and the waiver of subrogation endorsements. Not the certificate."

What it costs you if you get it wrong. A certificate of insurance is not coverage. A single Northgate certificate contained six defects, including a 34-day workers' compensation gap during active work on site and an employer's liability limit at half the required amount. If an installer had fallen during that gap, the shortfall lands on you — and so, potentially, does the injured worker's entire claim.

Clause 16 — Payment and performance bonds

Also called: bonds; contract security; surety bonds; bid bond, performance bond, payment bond; maintenance or warranty bond.

What it does, in plain English. A performance bond promises the owner that if you default, the surety completes the work or pays the cost of completion. A payment bond promises your subcontractors and suppliers that if you do not pay them, the surety will. Both are commonly written at 100% of contract value. A surety is not an insurer — it expects zero losses, and when it pays, it comes after you under the general indemnity agreement you signed.

Who it favors. The owner, and your subcontractors and suppliers. Not you.

What to look for. Which bond form governs — the owner's form or your surety's — because the form sets the procedure the owner must follow before calling on the surety, and an owner who skips a step may impair the bond. Whether bonds must be maintained through the correction period. Whether a separate maintenance or warranty bond is required and for how long. Whether you must bond your subcontractors, and at what threshold. Whether subcontractor default insurance is an acceptable substitute — public procurement codes often say no.

The question to ask before you sign. "Which bond form governs, and what does it require the owner to do before it can call on my surety?"

What it costs you if you get it wrong. Premium is real money on a sliding scale that improves with contract size: Northgate's payment and performance bonds run roughly $389,375 — an effective 0.82% — inside the $900,000 insurance-and-bonds line. Willow Street's run roughly $83,250 — 1.22%. The small job pays 49% more per dollar of contract than the big one, and if you bid small public work that spread comes straight out of your margin.

⚖️ Jurisdiction. Bond requirements on federal work run through the Miller Act; every state has its own version for state and local public work, collectively called "Little Miller Acts," and thresholds, notice periods, claim windows, and who counts as a claimant differ in every detail. Verify the one that governs your project.

Clause 17 — Warranty and the correction period

Also called: warranty of work; guarantee; correction of work; callback period; one-year warranty.

What it does, in plain English. Two different obligations that people constantly confuse. The warranty is your promise that the work conforms to the contract documents and is free of defects. The correction period — commonly one year from substantial completion under standard American forms — is a defined process during which the owner notifies you of defective work and you come back and fix it.

Who it favors. The owner. But the correction period also protects you, by giving a defined mechanism instead of an open argument.

What to look for. When the period starts — substantial completion of the whole project, final completion, or (in a badly drafted subcontract) the subcontractor's own completion. Get that wrong in a flow-down and a roofer who finishes eleven months before substantial completion warrants nothing by the time the owner moves in. Duration, and whether extended manufacturer warranties are required on top (a 20-year no-dollar-limit roofing warranty restricts the bidder list and changes the system, so it must be priced at bid). Whether corrected work restarts the warranty on that portion. Whether the owner may correct and backcharge, and after what notice.

The question to ask before you sign. "Does the warranty period start at substantial completion of the entire project — and does my subcontract flow that same start date down?"

What it costs you if you get it wrong. Northgate's TPO roof is 34,000 SF, and the roofer finishes long before the building does. A flow-down that starts the roofer's one-year warranty at the roofer's completion rather than the project's leaves you personally warranting the roof for the months between — and a roof callback is not a cheap callback.

⚖️ Jurisdiction. The correction period is not a statute of limitations. When it expires, your exposure for latent defects continues under whatever statute of limitations and statute of repose applies, and those vary substantially by jurisdiction in both length and in what event starts the clock. Do not repeat a number you heard on a job site.

Clause 18 — Consequential damages waiver

Also called: mutual waiver of consequential damages; limitation of liability; waiver of claims for lost profit and lost use.

What it does, in plain English. Both parties give up claims against each other for indirect losses — lost profits, lost use, lost revenue, lost financing, loss of reputation, loss of business opportunity. Liquidated damages are normally carved out and left intact, because the LD rate is the agreed substitute.

Who it favors. You, enormously. This is the most valuable clause in a construction contract from the contractor's side, and it is the one most often deleted quietly.

What to look for. Whether it is still there, and whether it is still mutual — a waiver edited to run only in the owner's favor is a common supplementary-conditions move. Whether liquidated damages are carved out (they should be). Whether the waiver survives termination. And whether it flows down to your subcontracts — if you waive against the owner and do not obtain the same waiver from your subs, you have kept an exposure you thought you had eliminated.

The question to ask before you sign. "Is the mutual waiver of consequential damages intact, and does it flow down to my subcontracts?"

What it costs you if you get it wrong. Northgate is a 132,000 SF outpatient building with clinics, an imaging suite, and ambulatory surgery. Without a waiver, a delayed opening exposes Kestrel to Meridian's lost clinical revenue — which dwarfs the $1,804,800 fee and can exceed the $47,500,000 contract itself. The waiver is worth more than the entire profit on the job.

Clause 19 — Dispute resolution and the escalation ladder

Also called: claims and disputes; resolution of disputes; mediation and arbitration; governing law and venue.

What it does, in plain English. It says where a fight goes and in what order — typically step negotiation, then mediation, then binding arbitration or litigation — and it names the governing law and the venue.

Who it favors. The drafter, mostly through venue and joinder.

What to look for. Whether mediation is a condition precedent to filing anything. Which forum is required and under whose rules. How decision-makers are selected. Joinder and consolidation — without a joinder right you can win against the owner and lose the identical issue against your subcontractor in a different forum, paying twice to litigate one fact. Venue, which can put your dispute a thousand miles from your office. Governing law, which decides every jurisdictional question in this appendix. Whether attorney's fees shift, and to whom. Whether an initial decision by the architect is a precondition to anything.

The question to ask before you sign. "If this becomes a three-party dispute involving the architect and my steel subcontractor, can I get all of them into one proceeding?"

What it costs you if you get it wrong. Field resolution and executive escalation settle the overwhelming majority of disputes and are the only levels where you still decide the outcome. Everything below costs more and controls less. Arbitration is not automatically cheaper or faster than trial, and grounds to vacate an award are extremely narrow — an arbitrator who gets it wrong usually stays wrong.

Clause 20 — Flow-down (incorporation of the prime contract into subcontracts)

Also called: incorporation by reference; conflicts and precedence; subcontractor's assumption of obligations; pass-through.

What it does, in plain English. It binds your subcontractor to the prime contract's terms as they apply to that subcontractor's work — so what you owe the owner, your subs owe you. It is the single most powerful clause in a subcontract and the one most often used carelessly.

Who it favors. You, against your subcontractors. And the owner, indirectly, because it makes the whole chain answer to one set of rules.

What to look for. Whether you actually gave the subcontractor the prime contract — attach it as an exhibit or state in the subcontract that it was made available and where. A subcontractor cannot fairly be bound to terms nobody showed it, and a judge asked to enforce a flowed-down term against a sub who never saw the document will not enjoy your argument. Whether the flow-down passes rights as well as obligations; many subcontracts flow down every burden and no benefit, which is legally effective and a good way to earn a reputation. Whether liquidated damages flow down and at what rate. And whether the notice periods create a sandwich that works.

The question to ask before you sign. "Is the prime contract attached to this subcontract, and does my subcontractor's notice period leave me enough time to notice the owner?"

What it costs you if you get it wrong. Meridian gives Kestrel 21 days to notice a claim. Kestrel's subcontracts require 7 days, leaving 14 days to evaluate and package. Set them equal and a sub who notices you on day 21 leaves you zero days — you are now liable for their claim with no ability to pass it through. And the sandwich only works if the middle moves: a sub notices on day 6, you sit on it for 20 days, and at day 26 you are five days past your own deadline. See Chapter 16.

Clause 21 — Allowances, alternates, and unit prices

Also called: cash allowances; contingency allowances; bid alternates; add and deduct alternates; schedule of unit prices.

What it does, in plain English. Three escape valves inside a fixed price. An allowance carries a stated dollar amount for scope known to exist but not yet designed, reconciled against actual cost at the end. An alternate is a priced option the owner may accept or decline. A unit price covers work whose quantity is genuinely uncertain, paid at a bid rate per measured unit.

Who it favors. Whoever wrote them carefully. All three are neutral tools that get abused in both directions.

What to look for. Whether the allowance amount includes overhead, profit, general conditions, and sales tax, or whether those are added at reconciliation — one sentence prevents a large argument. How and when reconciliation happens. For alternates on public work, whether the bid documents state the order in which alternates will be considered (accepting alternates out of order can change who the low bidder is). For unit prices: whether markup is included, whether the rate applies symmetrically to additions and deletions, and whether there is a quantity-variation clause letting either party renegotiate a unit price when actual quantity departs from the estimate by more than a stated percentage — 15% and 25% are both common, and thresholds vary by agency.

The question to ask before you sign. "Does this allowance amount include overhead, profit, general conditions, and sales tax — or are those added at reconciliation?"

What it costs you if you get it wrong. A $150,000 landscaping allowance against a $206,000 actual subcontract is a $56,000 direct adjustment, plus an argument about markup worth $5,600 at 10%. The same ambiguity on a $2,000,000 allowance is $200,000, and that one goes to mediation. Compare Northgate's good allowance, which nobody has ever argued about: $285,000 covering up to 3,800 CY of undercut at an agreed $75.00/CY, with quantities beyond that a change at the same rate. Both parties know exactly what happens at 3,801 cubic yards.

Clause 22 — Escalation and material price risk

Also called: price adjustment; material price escalation; commodity adjustment clause; economic price adjustment.

What it does, in plain English. It says what happens if raw-material prices move between the day you priced the work and the day you buy the material. Without one, the contractor owns the entire movement and prices it blindly into the bid.

Who it favors. Whoever ends up bearing the risk — and the honest point is that blind pricing is always more expensive than shared pricing, so a fair escalation clause usually saves the owner money.

What to look for. Three common shapes: index-based with a deadband (adjust if a published index moves more than a threshold; movement inside the band is the contractor's), threshold with sharing (contractor absorbs the first X%, then the parties share), and allowance (a stated reserve drawn against documented increases, unused portion returned). Then: which published index, who publishes it, on what date it is measured, which materials are covered, and — the one people forget — whether the clause is symmetric, adjusting downward as well as upward. An up-only clause is the kind of term a sophisticated owner strikes and remembers.

The question to ask before you sign. "Which published index governs, on what date is it measured, and is the adjustment symmetric?"

What it costs you if you get it wrong. Ironbridge Steel's subcontract carries $2,087,250 of mill material. A 12% price move is $250,470. Under Northgate's shared clause — Ironbridge absorbs the first 5%, the balance splits 50/50 — Kestrel pays $73,054. Without a clause, Ironbridge must carry the full $250,470 in its bid and Kestrel pays every dollar of it whether or not prices move. The clause is worth $177,416 if steel moves and costs $0 if it does not.

And the mechanism underneath all of it is the price hold: your entire escalation exposure is the gap between signing and locking the material price. I once lost $71,000 because I let a curtain-wall quote go stale for eighteen days arguing about a $9,000 scope gap in the sill flashing. I won the argument.

Clause 23 — Site investigation and the contractor's duty to inspect

Also called: examination of site and documents; contractor's investigation; site conditions representation; contractor's acknowledgment.

What it does, in plain English. It says you have visited the site, examined the documents, satisfied yourself as to the conditions, and included everything necessary in your price. It is short, it looks like boilerplate, and it is the clause that eats the differing-site-conditions clause.

Who it favors. The owner. Read Clauses 3 and 23 together or you have read neither.

What to look for. Whether it says you have satisfied yourself as to all conditions, including subsurface. Whether it disclaims reliance on owner-furnished geotechnical or environmental data. Whether it deems you to have discovered conditions that were not, in fact, reasonably discoverable in the bid period you were given — three weeks and a walk-through is not a subsurface investigation. Whether it conflicts with the differing-site-conditions clause, and which governs under the order of precedence.

The question to ask before you sign. "Read together, does the site-investigation clause take back what the differing-site-conditions clause gives me?"

What it costs you if you get it wrong. Northgate had 14 borings across 6.2 sloping acres, with a tight north property line against an active clinic whose buried utilities nobody had a good record of. Kestrel would not sign a broad site-investigation representation on that basis, and the resulting compromise — the $285,000 unsuitable soils allowance at $75.00/CY — exists precisely because somebody read these two clauses next to each other before the GMP was set. On a heavy civil job like Cottonwood Creek, where structural excavation runs $38.50/CY against 14,200 estimated CY, the same misreading is worth six figures on one bid item.

Clause 24 — Safety obligations and the multi-employer worksite

Also called: safety of persons and property; contractor's safety responsibility; site safety; compliance with laws.

What it does, in plain English. It makes you responsible for safety on the site — often for everyone's crews, not just your own — and it usually assigns you the obligation to comply with all applicable safety laws and regulations. On a job like Northgate, roughly 85% of craft hours belong to subcontractors you do not employ.

Who it favors. The owner, in liability terms. But the underlying duty is not really contractual: OSHA applies a multi-employer worksite policy under which more than one employer can be cited for a single hazard, based on the role each played — the employer that created it, the one whose people were exposed, the one responsible for correcting it, and the controlling employer with general supervisory authority over the site. A general contractor is very often the controlling employer, held to a standard of reasonable care, not perfection.

What to look for. Whether you are designated responsible for site safety generally, which is a broad assumption of duty for other companies' employees. Whether the owner reserves the right to direct means and methods, which mixes control and liability in a way your counsel should see. Whether your stop-work authority is unrestricted, and whether exercising it is an excusable delay. Whether safety metrics trigger liquidated damages or default — an incident-rate default provision creates a powerful incentive not to report. Who pays for required programs, orientation, and testing.

The question to ask before you sign. "Do I have unrestricted stop-work authority, and if I stop work for a hazard, is that an excusable delay?"

What it costs you if you get it wrong. Week 34 on Northgate: a scaffold plank lifted overnight by a trade that did not erect the scaffold and never re-secured, and a mason tender who stepped on it at 7:20 a.m. Nobody was hurt. The investigation found three failures, and the third was the one nobody wanted to write down — a crew running behind after the steel acceleration, with an unwritten "make it up" pressure. That pressure did not originate on the scaffold. It originated in a contract, travelled through a schedule, and arrived as an unsecured plank.

⚠️ Safety alert. Stack an aggressive contract time, $5,500/day in liquidated damages, a no-damage-for-delay clause, and float that belongs to the owner, and you have built a machine that converts every schedule slip into pressure on a crew that had nothing to do with it. Contract terms are a safety input.

⚖️ Jurisdiction. Application of the multi-employer policy has been litigated and has varied across federal circuits and over time, and state plans may take a different approach entirely.

Clause 25 — Audit rights and open-book reporting under a GMP

Also called: accounting records; owner's right to audit; cost of the work; reimbursable and non-reimbursable costs; savings and final accounting.

What it does, in plain English. On a cost-reimbursable or GMP contract, the owner is paying your actual costs, so the owner gets the right to inspect the records behind them — job cost detail, payroll, subcontracts, purchase orders, invoices, and change-order backup. Paired with it is the definition of the cost of the work, which decides which of your dollars are reimbursable at all.

Who it favors. The owner. And it is the fair price of an open book — you cannot ask an owner to pay actual cost and then decline to show it.

What to look for. The written definition of the cost of the work: the reimbursable and non-reimbursable schedules, the agreed labor burden rate, and the equipment rate schedule, attached. Without an attached rate schedule you will argue about whether an excavator is worth $185 or $310 an hour and neither side can prove it. How long records must be retained and how long the audit right survives final payment. Whether the auditor may reach your subcontractors' books, which lump-sum subs resist for good reason. How the savings split is calculated and when. Whether the contingency's unused balance is "savings" or returns to the owner in full.

The question to ask before you sign. "Show me the written definition of the cost of the work, the agreed labor burden, and the equipment rate schedule — are they attached to this agreement?"

What it costs you if you get it wrong. Meridian's auditor challenged four items in Kestrel's month-nine billing:

Three of four went against Kestrel, and the fourth is a drafting failure. All four outcomes were decided months before the invoice, by whether somebody wrote something down.

And the other side of the same clause, worth remembering when you negotiate: Northgate's construction contingency is $1,320,000, and the savings split returns 75% to Meridian and 25% to Kestrel. If it goes unspent, Meridian gets $990,000 back. The savings split is the single most valuable thing an owner gets from an open-book GMP, and owners routinely trade it away for a slightly lower fee.

G.4 The clause risk-scoring worksheet

One page. Apply it to a real contract in an hour and you will know where to spend your attorney's time and what to put in your bid.

How to score. For each clause, ask: how far has this been moved against me from a fair, balanced version?

Then weight it. Not all clauses move the same amount of money, so multiply.

Maximum weighted score is 129. Nobody has ever seen one.

The worksheet, filled in for Northgate. This is what a well-negotiated GMP looks like.

Now the lesson that makes the worksheet honest. Northgate scored 24 out of 129 — about as clean as a real contract gets. And on that job Kestrel still lost $43,650 on change order #14 and $244,950 to a submittal that sat on a desk for eleven days.

A low score does not protect you. It only means the contract will not be the thing that beats you. The worksheet tells you where the document is dangerous. Your notice calendar, your daily reports, your T&M tickets, and your schedule updates decide everything else.

📋 Try it. Take the last contract you signed — or the Willow Street documents in Appendix K — and score all 25 rows in one sitting. Then do the thing that actually matters: for every row you scored 2 or 3, write the dollar exposure next to it, with the arithmetic shown, using your project's own daily rates. On Willow Street those are $1,600/CD of extended general conditions and $2,800/CD of total exposure. A risk register full of adjectives is a wish list. A risk register with dollars in it is a negotiating position, and it is your Chapter 4 project deliverable.

G.5 One more time, because it matters

This appendix is not legal advice. It is a framework for spotting the issue and knowing what to ask.

Every jurisdictional flag in these twenty-five entries is real, and every one of them varies substantially by jurisdiction and changes over time. Verify each against a current, authoritative source for the state or country your project is in; write down where you found it and the date you checked; set a re-verification date. If you cannot find an authoritative answer in twenty minutes, the correct entry in your file is "unresolved — confirm with counsel." That is a professional answer. A wrong number is not.

Three sentences to carry out of here:

1. Read the supplementary conditions first. The general conditions are a known quantity; the supplement is where somebody was paid to move your risk.
2. Calendar every notice deadline the day the contract is executed. More valid claims die on this clause than on all the others combined.
3. When you find a clause you cannot live with, do not just flag it — price it. "This clause is unfair" is a complaint. "This clause is worth $154,500 to us on a plausible thirty-day delay, and here is what we will give you to change it" is a negotiation.
