The bid bond or bid security need not be for a specific sum but may be stated to be for a sum equal to 10% of the bid to which it relates. A bid bond or bid security may be stated as a certain stated sum provided that the sum is equal to or greater than 10% of the bid.
Bid or performance bonds shall not be used as a substitute for a determination of bidder responsibility. If a bid is withdrawn at any time before bid opening, any bid security shall be returned to the bidder.
Contracts for the purchase of material with a value less than the threshold amount(s) established by the Contracting and Purchasing Advisory Council may reduce or waive this bond requirement from the successful bidder. Such reduction or waiver shall be stated in the bid specifications.
