Liquidated damages in construction contracts

A liquidated damages (LD) clause sets a fixed amount the contractor owes for each day it finishes late, in place of the owner proving its actual losses. For an owner, that removes a hard proof problem. For a contractor, a well-drafted clause turns open-ended delay exposure into a known number. A badly drafted one does neither. This guide expands the damages section of our construction contract review checklist.

How liquidated damages work

The federal clause shows the basic mechanics. If the contractor doesn't complete the work on time, it pays a stated amount for each calendar day of delay until the work is completed or accepted. If the government terminates the contractor's right to proceed, liquidated damages keep accruing until the work is finished, on top of the excess cost of having someone else finish it (FAR 52.211-12). Federal rules tell contracting officers to build the daily rate from the government's estimated cost of inspection and superintendence plus other expected costs of late completion, such as renting substitute property (FAR 11.502).

A private owner's rate might reflect lost rent, extra financing carry, and extended fees for its architect and project manager. The question for you is whether the number in the contract bears any relationship to costs like those.

The enforceability test: forecast or penalty

Courts enforce liquidated damages that compensate and refuse to enforce ones that punish. The wording varies by state; the idea doesn't.

• New York. A clause will be sustained if the amount bears a reasonable proportion to the probable loss and the actual loss is incapable or difficult of precise estimation. If the amount is plainly or grossly disproportionate to the probable loss, it is a penalty and won't be enforced (Truck Rent-A-Center v. Puritan Farms 2nd, 1977).
• Texas. A court must find that the harm from the breach is incapable or difficult of estimation and that the amount is a reasonable forecast of just compensation, judged from the parties' perspective at signing. But the Texas Supreme Court also refused to enforce provisions where there was an "unbridgeable discrepancy" between the clause as written and the actual result, holding them a penalty (FPL Energy v. TXU Portfolio Management, 2014).
• California. In a commercial contract, a liquidated damages provision is valid unless the party challenging it proves it was unreasonable under the circumstances when the contract was made (Civ. Code § 1671(b)). The burden is on you, the contractor.
• Federal. The FAR says liquidated damages "are not punitive," the rate must be a reasonable forecast of just compensation, and the clause belongs only where timely performance matters and the damage would be hard to estimate or prove (FAR 11.501).

The practical lesson: enforceability is mostly judged as of signing, so the time to challenge a rate is before you sign. Ask the owner how the number was built. A rate it can't explain is your leverage in the negotiation, and an unlikely defense later.

Caps, end dates and exclusivity

Even the federal rules contemplate limits: contracting officers should use a maximum amount or a maximum period if those limits reflect the government's maximum probable damage (FAR 11.501(b)). On private work, these terms decide your worst case:

• A cap. A total limit, stated as a percentage of the contract sum or a fixed amount. Without one, a long delay can consume the fee and then some.
• An end date. LDs should stop at substantial completion, which A201-2017 § 9.8.1 defines as the point when the owner can occupy or use the work for its intended use, not at final completion. If the owner occupies part of the work early, the daily rate should drop in proportion.
• Exclusivity. The clause should say LDs are the owner's sole and exclusive remedy for delay. Language saying LDs "do not exclude" other delay damages lets the owner take the daily rate and still claim actual losses.
• Termination. If the owner terminates you, LDs should stop accruing, or at least be credited against the owner's completion costs, rather than run alongside them the way the federal clause allows.

How LDs interact with the consequential damages waiver

AIA A201-2017 § 15.1.7 contains a mutual waiver of consequential damages. Paraphrasing: the owner waives claims for items like rental expenses, loss of use, income, profit, financing, business and reputation, and lost management or employee productivity; the contractor waives claims for principal office expenses, financing, business and reputation losses, and lost profit other than anticipated profit arising directly from the work. The waiver applies to termination under Article 14. The section then states that it doesn't preclude liquidated damages where the contract documents provide for them.

Read the two together. The owner losses an LD rate is meant to price, such as lost rent and loss of use, largely fall in the categories the owner waives. So in an A201-based contract, LDs are often how the owner recovers delay losses at all, which is why AIA's own guidance describes using the two clauses together (AIA Contract Documents). Three edits to watch for:

• Waiver struck, LDs kept. Without the waiver and without an exclusive-remedy clause, the owner can argue for actual consequential losses on top of LDs.
• Waiver narrowed for the owner only. Carve-outs restoring the owner's lost profits or loss of use, while the contractor's waiver stays whole, break the trade the clause was built on.
• A rate out of proportion to the owner's real exposure. Ask what the daily number covers. If the answer is lost rent and loss of use, check it against the property's realistic rent and carrying costs.

Time extensions and concurrent delay

LDs run only for late completion that isn't excused, so your defense to them is a time extension. Under A201-2017 § 8.3.1, the Contract Time is extended for delays caused by the owner, the architect or a separate contractor, by changes, and by causes beyond the contractor's control, and time claims go through the Article 15 claims process (§ 8.3.2).

Follow the procedure even when the owner caused the delay. In Greg Opinski Construction v. City of Oakdale (Cal. Ct. App. 2011), the city was awarded $54,000 in liquidated damages because the contractor never used the contract's procedures for extending time. The trial court didn't decide who caused the late finish, and the appellate court affirmed, relying on Civil Code § 1511, which lets a contract require written notice of an intent to claim an extension. See our guide to notice provisions.

Concurrent delay, where both sides delay the job over the same period, is harder. The federal starting point, restated by the Federal Circuit, is that where both parties contribute to a delay, neither can recover damages unless the proof clearly apportions the delay and expense between them. The contractor claiming excusable delay must also show it delayed overall completion, meaning the critical path (Sauer Inc. v. Danzig, 2000). States vary, so don't leave it to the default rule: write down how concurrent periods are treated, and keep schedule updates that can show what drove the critical path.

What to negotiate

1. A daily rate the owner can tie to real costs, with its basis stated in the contract.
2. A total cap, stated as a percentage of the contract sum.
3. LDs end at substantial completion, scale down for partial occupancy, and stop at termination.
4. LDs are the owner's sole and exclusive remedy for delay, and the mutual consequential damages waiver stays intact.
5. No LDs for any period of excusable, compensable or concurrent delay.
6. Pass-through to subcontractors only in proportion to the delay each caused, capped at a percentage of the subcontract.
7. Optionally, an early-completion bonus at a matching daily rate. Even if the owner declines, the ask tests whether the rate reflects real value.

Illustrative language (our drafting; have counsel adapt it to your state):

If Contractor fails to achieve Substantial Completion by the Substantial Completion Date, as extended under the Contract Documents, Contractor shall pay Owner liquidated damages of $[__] per calendar day until Substantial Completion. The parties agree this amount is a reasonable estimate of damages that would be difficult to determine, and not a penalty. Liquidated damages are Owner's sole and exclusive remedy for delay in completion, shall not exceed [__]% of the Contract Sum in total, shall not accrue for any period of excusable or concurrent delay, and shall stop accruing upon Substantial Completion or termination of this Contract, whichever occurs first.

How RivetData flags this

RivetData sweeps seven review areas on every contract, damages among them, and reads the full set together: base agreement, general conditions, exhibits and addenda. That matters here, because the LD rate and the consequential damages waiver can sit in different documents, such as the agreement and the general conditions.
