(1) Designate the Government estimate as “For Official Use Only,” unless the information is classified. If it is, handle the estimate in accordance with security regulations.

(i) File a sealed copy of the Government estimate with the bids. (In the case of two-step acquisitions, this is done in the second step.)

(ii) After the bids are read and recorded, remove the “For Official Use Only” designation and read and record the estimate as if it were a bid, in the same detail as the bids.

(a)(70) Definition: “lump sum” means a single payment of money, as opposed to a series of payments made over time.

(i) An example of a line item with lump sum pricing in accordance with DFARS 204.71 is as follows:

Note that payment would occur upon completion and acceptance of the entire effort. Progress payments based on estimates of the percentage of completion (see FAR 52.232-5—Payments Under Fixed-Price Construction Contracts) could occur prior to that point.

(ii) An example of a line item with unit pricing in accordance with DFARS 204.71 is as follows:

Note that this allows the contractor to invoice for completed quantities of work, in accordance with FAR 32.102 (d), as those are accepted. Progress payments based on estimates of the percentage of completion (see FAR 52.232-5—Payments Under Fixed-Price Construction Contracts) could also occur prior to that point.

For additive or deductive items—

(1) Use a bid schedule with—

(i) A first or base bid item covering the work generally as specified; and

(ii) A list of priorities that contains one or more additive or deductive bid items that progressively add or omit specified features of the work in a stated order of priority. (Normally, do not mix additive and deductive bid items in the same solicitation.)

(2) Before opening the bids, record in the contract file the amount of funds available for the project.

(3) Determine the low bidder and the items to be awarded in accordance with the procedures in the clause at 252.236-7007, Additive or Deductive Items.

(b) When a technical working agreement with a foreign government is required for a construction contract—

(i) Consider inviting the Army Office of the Chief of Engineers, or the Naval Facilities Engineering Command, to participate in the negotiations.

(A) Acquisition of all necessary rights;

(B) Expeditious, duty-free importation of labor, material, and equipment;
