Contracts

What are liquidated damages in construction?

Liquidated damages (LDs) are a fixed amount, usually per calendar day, that a contractor agrees to pay the owner if the work is not finished by the contract completion date.

Liquidated damages are a price tag on lateness that both sides agree to before the job starts. The contract says something like "$1,500 per calendar day for each day beyond the substantial completion date." If the contractor finishes 20 days late, the owner can withhold $30,000 without proving what the delay actually cost. That is the trade: the owner skips the hard work of proving lost rent or extra financing, and the contractor gets a known, capped exposure instead of open-ended damages.

LDs are meant to compensate, not punish. Courts generally enforce them when the actual harm from delay would be hard to measure and the daily rate was a reasonable estimate when the contract was signed. A rate that is wildly out of line with any likely loss can be struck as a penalty.

How liquidated damages work on federal jobs

Federal construction contracts use FAR clause 52.211-12, Liquidated Damages, Construction. The contracting officer fills in a daily amount, and the contractor pays that amount for each calendar day of delay until the work is completed or accepted. If the government terminates the contractor's right to proceed, LDs keep running until the work is finished, on top of excess costs of reprocurement.

FAR 11.501 sets the policy. LDs should be used only when timely performance matters enough that the government expects to be harmed and the harm would be difficult or impossible to estimate or prove. The regulation says plainly that liquidated damages are not punitive and are not negative performance incentives. The rate must be a reasonable forecast of just compensation, and the contracting officer may set a maximum amount or period.

State and private contracts follow state law and the contract language. Some public owners publish standard daily rates by contract size. Read the rate, what date it runs from, and whether there is a cap.

A worked example

Say a GC has a $4.2 million retail build with a substantial completion date of June 30 and LDs of $2,000 per day. Rain and a late transformer push the finish to July 25, which is 25 days late. On the face of it, the owner withholds $50,000 from the final payment.

Now the GC's paperwork matters. If the GC sent timely notices of claim for 8 days of abnormal weather allowed under the contract, and the utility's transformer delay qualifies as an excusable delay for 10 days, the contract time extends by 18 days. LDs drop to 7 days, or $14,000. Without those notices, the GC likely eats the full $50,000.

The GC will also look at its subcontracts. Many pass LDs down to the trade that caused the delay, in proportion to its share. That only works if the subcontract says so and the delay can be traced.

Common disputes and mistakes

  • Missing the notice deadline. Most contracts require written notice of delay within a set number of days. Late notice often means no time extension.
  • Concurrent delay. When owner and contractor delays overlap, the parties argue over who owns which days.
  • Wrong end date. LDs usually stop at substantial completion, not final completion. Check the clause.
  • Owner-caused delay. Late approvals, slow RFI answers, and change orders can justify extensions. Track them as they happen.
  • Agreeing to LDs and actual damages. Some contracts try to collect both. Push back during negotiation.

LDs connect to the delay claim, the no damages for delay clause, weather delay provisions, and the recovery schedule an owner may demand when you fall behind. Smart Business Automator keeps daily logs, RFIs, and change orders tied to each job with dates, so a time extension request has the backup ready. See construction workflow automation.

Frequently asked questions

Are liquidated damages a penalty?

They are not supposed to be. Liquidated damages are meant to be a reasonable estimate of the owner's loss from delay. A rate far above any likely loss may be unenforceable as a penalty under state law.

Do liquidated damages run on weekends?

Often yes. Many contracts, including the federal clause, measure LDs in calendar days. Read your contract to confirm.

Can a GC pass liquidated damages to subcontractors?

Only if the subcontract allows it. Most GC forms include a flow-down that charges a sub for its share of the delay, but the GC still has to show the sub caused it.

What happens if there is no liquidated damages clause?

The owner can still try to recover actual delay damages, but must prove them. That can expose the contractor to a larger amount than an LD rate would have.
