This indicates a cost analysis would be required for a fixed price contract when price analysis is not able to be determined.
15.305 -- Proposal Evaluation.
(a) Proposal evaluation is an assessment of the proposal and the offeror’s ability to perform the prospective contract successfully. An agency shall evaluate competitive proposals and then assess their relative qualities solely on the factors and subfactors specified in the solicitation. Evaluations may be conducted using any rating method or combination of methods, including color or adjectival ratings, numerical weights, and ordinal rankings. The relative strengths, deficiencies, significant weaknesses, and risks supporting proposal evaluation shall be documented in the contract file.
(1) Cost or price evaluation. Normally, competition establishes price reasonableness. Therefore, when contracting on a firm-fixed-price or fixed-price with economic price adjustment basis, comparison of the proposed prices will usually satisfy the requirement to perform a price analysis, and a cost analysis need not be performed. In limited situations, a cost analysis (see 15.403-1(c)(1)(i)(B)) may be appropriate to establish reasonableness of the otherwise successful offeror’s price. When contracting on a cost-reimbursement basis, evaluations shall include a cost realism analysis to determine what the Government should realistically expect to pay for the proposed effort, the offeror’s understanding of the work, and the offeror’s ability to perform the contract. Cost realism analyses may also be used on fixed-price incentive contracts or, in exceptional cases, on other competitive fixed-price-type contracts (see 15.404-1(d)(3)). (See 37.115 for uncompensated overtime evaluation.) The contracting officer shall document the cost or price evaluation.
