# §11.503. Contract clauses.

- (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)](#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)](#b) of this section.
