General Contractor Contract Review: A Practical Guide
A general contractor sits in the middle of every contractual relationship on a project. Upstream is the Owner, with an agreement that defines what the GC is obliged to deliver and on what terms. Downstream are dozens of subcontractors and suppliers, each with an agreement that determines whether the GC can actually perform those obligations without carrying the risk alone. The GC's commercial position is defined not by either contract individually but by the alignment between them.
That is what makes GC contract review different from reviewing a single agreement. The question is never just what does this contract say. It is what does this contract require of me, what have I passed down, and where is the gap. Gaps between the prime contract and the subcontracts are where general contractors lose money, and they are almost always created at contract execution rather than discovered during the project.
This guide covers the contracts a GC manages, the risks in the Owner agreement, what must flow down to subcontracts, the payment traps that carry the most exposure, and how AI handles full package review.
The Contracts a GC Manages
The prime contract. The Owner-GC agreement is the source of every obligation the GC carries. On US commercial work this is typically an AIA A101 or A102 Owner-Contractor Agreement paired with A201 General Conditions, or a ConsensusDocs 200. It defines scope, price, schedule, payment terms, change procedures, claim requirements, insurance obligations, and dispute resolution. Everything downstream is derived from it.
Subcontracts. Each trade subcontract must pass down the relevant prime contract obligations while allocating risk appropriately for the trade's scope. On a mid-size commercial project a GC might issue 25 to 40 subcontracts, each requiring the same alignment check against the prime. AIA A401 and ConsensusDocs 750 are the standard subcontract forms, though many GCs use their own house form built from one of these.
Purchase orders. Material and equipment POs are often treated as administrative rather than contractual, which is a mistake. A PO for long-lead equipment carries delivery risk that maps directly onto the GC's schedule obligation under the prime contract. Where the PO has no liquidated damages provision, no delivery guarantee, and a limitation of liability capped at the purchase price, the GC absorbs the difference between the supplier's exposure and the delay damages the Owner will assess.
Design agreements. On design-build or where the GC holds any design responsibility, the agreement with the design professional must align the standard of care with what the prime contract requires. If the prime imposes a performance or fitness-for-purpose obligation and the design agreement provides only professional standard of care, the GC carries the gap uninsured.
The review discipline that matters is treating these as one package rather than four separate reviews. The prime contract sets the requirements. Everything else is checked against it.
Key Risks in the Owner-GC Agreement
Scope definition and the completeness of the Contract Documents. The most expensive disputes on US commercial projects originate in scope ambiguity. Check what the Contract Documents comprise, how conflicts between them are resolved, and whether the order of precedence clause puts the drawings above the specifications or the reverse. Where the design is incomplete at execution, confirm how design development is treated: as included in the price or as a change.
Schedule obligations and delay damages. Confirm the Substantial Completion date, whether there are interim milestones with separate damages, and the liquidated damages rate. Calculate total exposure across all milestones running simultaneously. Check whether the contract contains a no-damages-for-delay clause, which limits the GC to a time extension with no cost recovery for Owner-caused delay. Enforceability varies by state, with exceptions in many jurisdictions for active interference or bad faith, but pricing the risk on the assumption it will be enforced is the conservative approach.
Change order procedure. Under AIA A201 Section 7.3, a Construction Change Directive requires the GC to proceed with directed work before price and time are agreed. Check whether the standard CCD compensation has been modified to cap markup or exclude cost categories. Check the notice requirements for change order claims and whether they impose forfeiture for late submission.
Indemnification and insurance. AIA Section 3.18 indemnity is frequently expanded by Owner modification beyond what state anti-indemnity statutes permit. Check the scope against the project's state law. Check Article 11 insurance requirements against what the GC's programme actually provides and what is commercially available. Additional insured requirements, waiver of subrogation, and required policy endorsements all need confirming with the broker before signing, not after.
Termination for convenience. AIA Section 14.4 entitles the GC to payment for work executed plus costs of termination including overhead and profit on work not executed. Owner modifications commonly reduce this to costs only. On a project requiring significant mobilisation, that reduction is a material exposure.
Consequential damages waiver. AIA Section 15.1.7 contains a mutual waiver covering the Owner's loss of use, income, profit, and financing. This is among the most valuable protections in the standard form. Any deletion or one-sided carve-out should be flagged and quantified, because loss-of-revenue claims on a commercial property can exceed contract value.

Flow-Down: What Must Pass to Subcontracts
Flow-down is the mechanism by which prime contract obligations are imposed on subcontractors. A general incorporation clause stating that the subcontractor assumes toward the GC all obligations the GC assumes toward the Owner is standard, but general incorporation alone is not sufficient. Courts in many states have declined to enforce prime contract provisions against subcontractors where the subcontract did not address them specifically, particularly for dispute resolution and damages provisions.
The provisions that require specific flow-down are the following.
Notice and claim deadlines. If the prime requires claim notice within 21 days, the subcontract must require notice from the subcontractor early enough that the GC can still meet its own upstream deadline. A subcontract requiring 21 day notice to the GC leaves zero time to prepare and submit the prime claim. Subcontract notice periods must be shorter than prime periods, not equal to them.
Schedule and delay damages. Where the prime imposes liquidated damages, the subcontract must give the GC a route to recover those damages from the responsible trade. A subcontract with no delay damages provision leaves the GC absorbing LDs caused by a subcontractor's failure.
Insurance and indemnity. Required coverage types, limits, additional insured status, and waiver of subrogation must all pass down at levels that satisfy the prime. Check that the required limits are appropriate to the trade: a demolition or steel erection subcontractor carries different exposure from a finishes trade.
Change order procedures. The subcontract change procedure must produce the documentation the GC needs to substantiate its own change request upstream, within the timeframe the prime requires.
Dispute resolution. Where the prime requires arbitration, the subcontract should permit joinder or consolidation so the GC is not litigating the same facts in two forums with inconsistent outcomes.
Lien waivers and payment documentation. Conditional and unconditional waiver requirements, and any requirement for subcontractor and supplier waivers before the GC's own payment application is accepted, must flow down or the GC cannot satisfy its upstream obligation.
The systematic check is straightforward in principle and time-consuming in practice: for each material obligation in the prime, confirm the corresponding subcontract provision exists and is at least as protective. Doing this manually across 30 subcontracts is where the discipline usually breaks down.
Payment Risk and the Pay-if-Paid Trap
Payment is where GC contract structure has the most direct cash flow consequence, and pay-if-paid is the provision that carries the most risk in both directions.
The distinction. Pay-when-paid is generally construed as a timing mechanism: the GC has a reasonable time to pay the subcontractor after receiving payment from the Owner, but the obligation to pay is not contingent on receiving it. Pay-if-paid is a condition precedent: the subcontractor is paid only if the GC is paid, which shifts Owner insolvency risk down the chain.
Enforceability varies by state, substantially. Some states enforce clearly drafted pay-if-paid clauses as genuine conditions precedent. Others, including California and New York, treat them as unenforceable against public policy or construe them as pay-when-paid timing provisions regardless of the drafting. A number of states require explicit condition precedent language before the clause will be given that effect. The practical consequence is that a GC relying on pay-if-paid protection in a state that does not enforce it is carrying Owner credit risk it believed it had transferred.
Both sides of the risk. As the party issuing subcontracts, the GC benefits from enforceable pay-if-paid. As the party receiving payment from the Owner, the GC needs to confirm that the prime contract does not contain provisions allowing the Owner to withhold payment for reasons the GC cannot control, because that withholding cascades down and the GC absorbs the timing gap if its subcontracts do not have matching protection.
Prompt payment statutes overlay everything. Most states have prompt payment acts imposing statutory payment deadlines and interest on late payment, and many apply to private as well as public work. These statutes can override contractual payment terms and in some states expressly limit pay-if-paid enforceability. The applicable state act needs checking alongside the contract terms.
Retainage. Confirm the retainage percentage in the prime, whether it reduces at any milestone, and what conditions attach to release. Then confirm the subcontract retainage is at least equal and releases no earlier. A GC holding 10 percent from subcontractors while the Owner holds 10 percent from the GC is neutral. A GC holding 5 percent while the Owner holds 10 percent is financing the difference across every trade for the life of the project.
How AI Reviews GC Contract Packages
The specific value of AI for general contractors is cross-document analysis. Reviewing a single contract is useful. Reviewing a prime contract against 30 subcontracts and identifying every misalignment is the task that manual review cannot do reliably at speed, and it is where the GC's actual exposure sits.
AI reads the prime contract and the subcontract package together and identifies gaps: notice periods that do not leave time for upstream compliance, insurance requirements that are not passed down at the required limits, indemnity provisions that do not mirror the prime obligation, delay damages exposure with no downstream recovery route, and dispute resolution provisions that create inconsistent forums.
For the prime contract itself, the analysis covers the modifications to the standard form: indemnification scope against the AIA A201 or ConsensusDocs baseline, insurance requirements, consequential damages waiver status, termination compensation, change directive mechanics, and payment certification and withholding grounds.
AI also extracts every notice deadline and obligation from the full package into a single calendar. On a project with a prime contract and 30 subcontracts, each with its own notice requirements, the number of live deadlines at any point runs into the hundreds. Tracking them manually across spreadsheets is where deadlines get missed and entitlement gets lost.
The state law layer remains a legal question. AI flags the provisions that interact with state statutes, including indemnity against anti-indemnity acts, pay-if-paid enforceability, no-damages-for-delay treatment, and lien waiver requirements, but confirming the position in a specific jurisdiction requires counsel licensed in that state.

Frequently Asked Questions
What should a general contractor check before signing an owner contract?
The highest-consequence items are: scope definition and the order of precedence among Contract Documents; the Substantial Completion date, interim milestones, and total liquidated damages exposure across all milestones; whether a no-damages-for-delay clause limits recovery for Owner-caused delay; the change order and Construction Change Directive procedure including any caps on markup; indemnification scope checked against the project state's anti-indemnity statute; insurance requirements confirmed as commercially available and consistent with the existing programme; termination for convenience compensation; and whether the mutual consequential damages waiver remains intact. Each should be quantified before pricing, not after signing.
What does flow-down mean in construction contracts?
Flow-down is the mechanism by which obligations in the prime contract are imposed on subcontractors through the subcontract. A general incorporation clause stating the subcontractor assumes toward the contractor all obligations the contractor assumes toward the owner is standard, but many courts have declined to enforce specific prime provisions against subcontractors where the subcontract did not address them expressly. Notice deadlines, delay damages, insurance and indemnity requirements, change procedures, dispute resolution, and lien waiver obligations should all be specifically addressed rather than relying on general incorporation alone.
What is the difference between pay-when-paid and pay-if-paid?
Pay-when-paid is generally construed as a timing provision: the contractor has a reasonable period to pay the subcontractor after receiving owner payment, but the payment obligation itself is not contingent. Pay-if-paid is a condition precedent: the subcontractor is paid only if the contractor is paid, transferring owner insolvency risk down the chain. Enforceability varies significantly by state. Some jurisdictions enforce clearly drafted pay-if-paid clauses, others treat them as unenforceable or construe them as timing provisions regardless of drafting, and several require explicit condition precedent language. The applicable state law determines which effect the clause actually has.
How do subcontract notice periods need to align with the prime contract?
Subcontract notice periods must be shorter than the corresponding prime contract periods, not equal to them. If the prime requires claim notice within 21 days of the event, a subcontract requiring 21 day notice to the contractor leaves no time to evaluate the subcontractor's claim, prepare the upstream submission, and serve it within the prime deadline. A practical margin is a subcontract period of roughly half the prime period, giving the contractor time to assess, document, and submit. Misaligned notice periods are among the most common flow-down failures and the consequence is the contractor absorbing a claim it could have passed upstream.
Can AI review a full contract package including subcontracts?
Yes, and cross-document analysis is where AI adds the most value for general contractors. A construction-specific platform reads the prime contract and subcontract package together and identifies misalignments: notice periods that do not leave time for upstream compliance, insurance requirements not passed down at required limits, indemnity provisions that do not mirror the prime obligation, and delay damages exposure with no downstream recovery route. It also consolidates every notice deadline across the full package into a single calendar. Confirming state law questions such as indemnity enforceability and pay-if-paid effect remains work for counsel licensed in the project jurisdiction.
