FAR 52.211-11—Liquidated Damages-Supplies, Services, or Research and Development.
Plain-English Summary
FAR 52.211-11 is the standard liquidated damages clause for fixed-price contracts for supplies, services, or research and development when the Government wants a pre-set remedy for late delivery or late performance. It covers four main topics: the contractor’s obligation to pay liquidated damages for delay, the contracting officer’s duty to insert the dollar amount per calendar day, the effect of a Government termination for default on the running of liquidated damages, and the contractor’s protection from liquidated damages when delay is excusable under the Default-Fixed-Price Supply and Service clause. In practice, the clause lets the Government recover a reasonable, agreed-upon amount without having to prove actual damages for every day of lateness, which is especially useful when late performance causes administrative burden, mission disruption, or hard-to-measure losses. It also coordinates with the default clause and the termination clause so the Government can recover both liquidated damages and excess reprocurement costs where appropriate, but not double count the same harm. For contractors, the clause creates a real cost for schedule slippage and makes it important to document excusable delays, manage subcontractors, and understand when liquidated damages stop accruing after termination or replacement performance is obtained.
Key Rules
Liquidated damages replace actual damages
If the contractor misses the required delivery or performance date, the contractor must pay the stated daily amount instead of the Government proving actual damages. The clause is intended to set a reasonable pre-estimate of harm from delay, not a penalty.
Contracting officer sets the daily amount
The clause requires the contracting officer to insert the dollar amount per calendar day of delay. That amount should be based on the anticipated harm from late delivery or performance and should be supportable as a reasonable estimate at the time of contracting.
Applies to supplies, services, and R&D
This clause is prescribed for solicitations and contracts involving supplies, services, or research and development when liquidated damages are appropriate. It is used in fixed-price settings where late performance can be measured by days of delay.
Damages continue after default termination
If the Government terminates the contract in whole or in part for default, liquidated damages continue to accrue until the Government reasonably obtains similar supplies or services. This is in addition to excess reprocurement costs under the termination clause.
Excusable delay stops the charge
The contractor is not charged liquidated damages for delay beyond its control and without its fault or negligence, as defined in the Default-Fixed-Price Supply and Service clause. The contractor must show the delay qualifies as excusable under that clause.
No double recovery for the same harm
The clause works with the termination and default provisions to avoid improper overlap, but it expressly allows liquidated damages plus excess repurchase costs after default termination. The Government still must apply the clauses consistently and only for the periods and harms covered.
Responsibilities
Contracting Officer
Determine whether liquidated damages are appropriate for the acquisition, insert the daily dollar amount in the clause, and ensure the amount is a reasonable forecast of likely Government harm from delay. The contracting officer must also coordinate this clause with the default and termination clauses so the contract remedies are consistent.
Contractor
Deliver the supplies or complete the services/R&D effort by the required date, monitor schedule risk, and pay liquidated damages for each calendar day of non-excusable delay. The contractor should document any excusable delay and notify the Government promptly when events beyond its control affect performance.
Government
Track late performance, calculate liquidated damages accurately, and stop charging them when the Government reasonably obtains similar supplies or services after a default termination. The Government must also apply the excusable-delay standards fairly and avoid charging liquidated damages for delays outside the contractor’s control and without fault or negligence.
Subcontractors and suppliers
Although not directly bound by the clause unless incorporated elsewhere, their performance can affect the prime contractor’s schedule. The prime contractor must manage them carefully because their delays may or may not be excusable depending on the contract terms and the circumstances.
Practical Implications
This clause gives the Government a simple, enforceable remedy for late performance, so schedule control matters as much as technical compliance and price.
Contractors should treat the daily liquidated damages amount as a real financial exposure and build in schedule margin, supplier oversight, and documentation of excusable delays.
A common pitfall is assuming any delay excuse automatically eliminates liquidated damages; the delay must fit the default clause’s excusable-delay standard and be properly supported.
After a default termination, liquidated damages do not automatically stop on the termination date; they continue until the Government reasonably secures similar performance, which can materially increase exposure.
Contracting officers should be careful to set a defensible daily amount at award, because an unsupported or excessive amount can create disputes over whether the clause is a valid liquidated damages provision or an unenforceable penalty.

These liquidated damages are in addition to excess costs of repurchase under the Termination clause. (c) The Contractor will not be charged with liquidated damages when the delay in delivery or performance is beyond the control and without the fault or negligence of the Contractor as defined in the Default-Fixed-Price Supply and Service clause in this contract.
