(c)(i) If the acquisition is by sealed bidding, the contracting officer shall file a sealed copy of the detailed Government estimate with the bids until bid opening. After the bids are read and recorded, the contracting officer shall read the estimate, and record it in the same detail as the bids.

(ii) If the acquisition is by negotiation, the contracting officer may disclose the overall amount of the Government estimate after award upon request of offerors.

When it appears that funds available for a project may be insufficient for all the desired features of construction, the contracting officer may provide in the invitation for bids for a first or base bid item covering the work generally as specified and one or more additive or deductive bid items progressively adding or omitting specified features of the work in a stated order of priority. In such case, the contracting officer, before the opening of bids, shall record in the contract file the amount of funds available for the project and determine the low bidder and the items to be awarded in accordance with the provision at 1852.236–71, Additive or Deductive Items.

For additional guidance on the use of FAR clause 52.236–13, Accident Prevention, and its Alternate I in NASA contracts, see 1823.7001(d).
