Section 36.605 - Government cost estimate for architect-engineer work(a) An independent Government estimate of the cost of architect-engineer services shall be prepared and furnished to the contracting officer before commencing negotiations for each proposed contract or contract modification expected to exceed the simplified acquisition threshold. The estimate shall be prepared on the basis of a detailed analysis of the required work as though the Government were submitting a proposal.(b) Access to information concerning the Government estimate shall be limited to Government personnel whose official duties require knowledge of the estimate. An exception to this rule may be made during contract negotiations to allow the contracting officer to identify a specialized task and disclose the associated cost breakdown figures in the Government estimate, but only to the extent deemed necessary to arrive at a fair and reasonable price. The overall amount of the Government's estimate shall not be disclosed except as permitted by agency regulations.48 FR 42356, Sept. 19, 1983, as amended at 62 FR 44829, Aug. 22, 1997; 71 FR 57368, Sept. 28, 2006
