As prescribed in 28.101-2, insert a provision or clause substantially as follows: Bid Guarantee (SEP 1996) (a) Failure to furnish a bid guarantee in the proper form and amount, by the time set for opening of bids, may be cause for rejection of the bid.

The Contracting Officer will return bid guarantees, other than bid bonds, (1) to unsuccessful bidders as soon as practicable after the opening of bids, and (2) to the successful bidder upon execution of contractual documents and bonds (including any necessary coinsurance or reinsurance agreements), as required by the bid as accepted. (c) The amount of the bid guarantee shall be ____ percent of the bid price or $____, whichever is less. (d) If the successful bidder, upon acceptance of its bid by the Government within the period specified for acceptance, fails to execute all contractual documents or furnish executed bond(s) within 10 days after receipt of the forms by the bidder, the Contracting Officer may terminate the contract for default. (e) In the event the contract is terminated for default, the bidder is liable for any cost of acquiring the work that exceeds the amount of its bid, and the bid guarantee is available to offset the difference.

28.101-2
(a) The contracting officer shall insert a provision or clause substantially the same as the provision at 52.228-1, Bid Guarantee, in solicitations or contracts that require a bid guarantee or similar guarantee. For example, the contracting officer may modify this provision-
(1) To set a period of time that is other than 10 days for the return of executed bonds;
(2) For use in connection with construction solicitations when the agency has specified that only separate bid bonds are acceptable in accordance with 28.101-1(b);
(3) For use in solicitations for negotiated contracts; or
(4) For use in service contracts containing options for extended performance.
(b) The contracting officer shall determine the amount of the bid guarantee for insertion in the provision at 52.228-1 (see 28.102-2(a)). The amount shall be adequate to protect the Government from loss should the successful bidder fail to execute further contractual documents and bonds as required. The bid guarantee amount shall be at least 20 percent of the bid price but shall not exceed $3 million. When the penal sum is expressed as a percentage, a maximum dollar limitation may be stated.
