How to Review a Construction Contract Before You Sign
Most construction disputes are about money and time. Read the contract in the order risk actually shows up: price, payment, changes, schedule, then risk-shifting clauses.

Overview
A construction contract decides who carries the risk when a job runs long, costs more, or goes wrong. The dangerous terms are rarely in the scope — they are in the payment, change-order, delay, indemnity, and lien language.
Read in this order: the price basis (lump sum, cost-plus, or GMP), the payment and retainage terms, the change-order process, the schedule and delay damages, then the risk-shifting clauses — indemnity, insurance and bonds, lien waivers, and termination.
Topics to check
Confirm the price basis: a fixed lump sum, cost-plus (with or without a guaranteed maximum), or a GMP. Then read how and when you get paid: the schedule of values, the application and certification process, the time the payer has to pay, and any condition that lets the payer hold or delay money.
Find the retainage percentage and — more importantly — when it is released. Retainage held until final completion of the entire project can tie up a subcontractor’s profit for many months after its own work is finished.
Read the change-order clause: whether changes require a signed written order before work, how extras are priced, markup limits, and whether directed or oral changes are compensable. Many payment fights start with work performed on a verbal instruction that the contract says is not payable.
Then read the schedule terms: the completion date, whether time is "of the essence," liquidated damages for delay (and whether they are capped), and any no-damages-for-delay clause that limits you to a time extension even when the other side caused the delay.
Liquidated damages (Cornell LII Wex)Read indemnity together with the insurance and additional-insured requirements; a broad-form indemnity that covers the other party’s own negligence is limited or void by anti-indemnity statutes in many states. Check lien rights and any lien-waiver-as-condition-of-payment language, whether performance and payment bonds are required, and the termination clause — for cause and for convenience — including what you are paid if the job is terminated.
These risk-shifting clauses decide who absorbs a loss when something goes wrong, so they deserve as much attention as the price.

- Review price basis, payment, retainage, changes, schedule, then risk-shifting clauses in that order.
- Retainage released only at whole-project completion can trap a sub’s profit for months.
- A written-change-order requirement can make verbally directed work non-payable.
- Broad-form indemnity and no-damages-for-delay clauses are limited in many states.
- Confirm lien rights, bonds, and termination-payment terms before you sign.

- Pay-if-paid, no-damages-for-delay, anti-indemnity, lien, retainage, and prompt-payment rules are state- and project-specific (public vs. private).
- Have a construction attorney in the project’s state review high-stakes terms before signing.

Frequently asked questions
What is the most important part of a construction contract to review?
The payment terms (including contingent-payment and retainage language), the change-order process, and the delay and indemnity clauses. Those decide whether you get paid, get paid on time, and who absorbs the cost of delay or a loss.
Can a construction contract be negotiated?
Often yes — retainage release, change-order markup, delay-damage caps, indemnity scope, and payment timing are commonly negotiated, especially on private projects. The leverage is highest before you sign.
Is this legal advice?
No. This is general information for issue-spotting. Construction-contract enforceability — pay-if-paid, no-damages-for-delay, indemnity, lien and lien-waiver rules, retainage limits, and prompt-payment rights — varies by state and by whether the project is public or private, so confirm high-stakes points with a construction attorney licensed in the project’s state.
