FAR 11.503 Contract clauses.

The codified text (eCFR, as of 2026-10-02). Under the Revolutionary FAR Overhaul ↗, agencies follow class deviations with new text for many parts while the formal rules go through the Federal Register: check the solicitation and your contract's clauses, which rule.

In plain English

This section tells contracting officers which liquidated damages clauses to include in certain solicitations and contracts. It matters to contractors because it determines whether a contract will contain liquidated damages provisions and, for construction contracts with multiple completion dates, how those damages are structured.

Applies to: Contracting officers preparing solicitations and contracts for supplies, services, research and development, or construction

Key terms: liquidated damages · fixed-price solicitations and contracts · construction · cost-plus-fixed-fee · completion date

The text

(a) Use the clause at 52.211-11, Liquidated Damages—Supplies, Services, or Research and Development, in fixed-price solicitations and contracts for supplies, services, or research and development when the contracting officer determines that liquidated damages are appropriate (see 11.501(a)).

(b) Use the clause at 52.211-12, Liquidated Damages—Construction, in solicitations and contracts for construction, other than cost-plus-fixed-fee, when the contracting officer determines that liquidated damages are appropriate (see 11.501(a)). If the contract specifies more than one completion date for separate parts or stages of the work, revise paragraph (a) of the clause to state the amount of liquidated damages for delay of each separate part or stage of the work.

(c) Use the clause at 52.211-13, Time Extensions, in solicitations and contracts for construction that use the clause at 52.211-12, Liquidated Damages—Construction, when that clause has been revised as provided in paragraph (b) of this section.
