Section 931.205-32 - Pre-contract costs(a) To the extent practical, known expenditures of pre-contract costs under DOE contracts should be governed by establishing advance understandings as contemplated by 48 CFR 31.109 . Contracts that include authorized precontract costs shall include the "Date of Incurrence of Cost" clause specified at 952.231-70.(b) The following limitations apply to establishment of advance understandings relative to pre-contract costs:(1) Pre-contract cost authorizations shall not be used to cover a period in excess of 15 days, unless a longer period is approved by the HCA based upon a written finding that such an allowance is reasonable, and shall not be extended or renewed. A copy of the findings shall be forwarded to the Senior Procurement Executive at the time of approval. If prolonged coverage is necessary, a letter contract shall be issued.(2) All pre-contract cost authorizations shall be reviewed and approved at a management level above the contracting officer.(3) Retroactive precontract cost authorization and the predating of contractual agreements shall not be used.(4) Pre-contract cost authorizations shall not authorize the delivery or furnishing of any goods or services from a contractor until after the contract is executed.49 FR 12011, Mar. 28, 1984; 49 FR 38951, Oct. 2, 1984, as amended at 74 FR 36366, 36378, July 22, 2009; 75 FR 29459, May 26, 2010
