FAR 52.211-12—Liquidated Damages-Construction.
Plain-English Summary
FAR 52.211-12, Liquidated Damages-Construction, tells the parties what happens when a construction contractor finishes late. It covers the contracting officer’s authority to insert a daily liquidated damages amount, the contractor’s obligation to pay that amount for each calendar day of delay, when the damages stop accruing (completion or acceptance of the work), and what happens if the Government terminates the contractor’s right to proceed. It also makes clear that liquidated damages can continue after termination until the work is completed, and that those damages are separate from any excess repurchase or reprocurement costs charged under the termination clause. In practice, the clause is a pre-agreed remedy for late completion, intended to estimate the Government’s likely loss from delay without having to prove actual damages day by day. For contractors, it creates a direct financial incentive to meet the completion date and to understand that delay exposure may continue even after a termination for default or similar action. For contracting officers, it requires careful selection of the daily amount and careful administration so the clause is applied consistently with the contract schedule, completion/acceptance status, and any termination action.
Key Rules
Daily damages for late completion
If the contractor does not complete the work within the contract time, it must pay liquidated damages for each calendar day of delay. The amount is set by the contracting officer in the contract and applies until the work is completed or accepted.
Amount must be inserted by CO
The clause contains a blank for the daily liquidated damages rate, which the contracting officer must fill in. The amount should reflect the Government’s anticipated loss from delay and be established before award.
Damages run until completion or acceptance
Liquidated damages continue to accrue day by day until the work is completed or accepted, not merely until substantial completion or partial use unless the contract or acceptance action says otherwise. The stop date depends on the contract’s completion and acceptance terms.
Damages continue after termination
If the Government terminates the contractor’s right to proceed, liquidated damages do not automatically stop. They continue to accrue until the work is completed, even though the Government may also pursue other termination remedies.
Separate from repurchase costs
Liquidated damages are in addition to excess costs of repurchase or reprocurement under the termination clause. The Government may recover both types of amounts if the facts and contract terms support them.
Responsibilities
Contracting Officer
Determine whether liquidated damages are appropriate for the construction requirement, insert the daily amount in the contract, and administer the clause consistently with the contract schedule, completion, acceptance, and any termination action. The contracting officer must also ensure the amount is supportable as a reasonable forecast of delay damages.
Contractor
Complete the work within the required time, monitor schedule performance, and understand that late completion triggers daily liquidated damages. If the contractor is delayed, it must account for the financial exposure and cannot assume damages stop merely because the Government terminates the right to proceed.
Government/Agency
Use the clause to protect the Government from the costs and operational impacts of delayed construction, including administrative burden, lost use, and other delay-related harms. The agency must also coordinate any termination and recovery actions so liquidated damages and repurchase costs are handled correctly.
Practical Implications
This clause creates a predictable daily cost for late completion, so schedule control is critical on construction jobs. Contractors should treat the liquidated damages rate as a real budget risk and manage critical path delays aggressively.
A common pitfall is assuming liquidated damages stop when the Government terminates the contractor’s right to proceed. Under this clause, they continue until the work is completed, so termination does not eliminate delay exposure.
Another frequent issue is confusion over when the clock stops. The key event is completion or acceptance of the work, so parties should document substantial completion, punch-list status, and formal acceptance carefully.
Contracting officers should make sure the daily amount is reasonable and tied to anticipated Government losses from delay. If the amount is arbitrary or punitive, it may be vulnerable to challenge.
Because liquidated damages are separate from excess repurchase costs, the Government may pursue both where appropriate. Contractors should evaluate termination exposure broadly, not just the daily damages amount.
Official Regulatory Text
