A.
Bid security shall be required for all competitive sealed bidding for construction contracts when the price is estimated by the designated official for construction contracting management to exceed $50,000. Bid security shall be a bond provided by a surety company authorized to do business in the state, or the equivalent in cash, or otherwise supplied in a form satisfactory to the Director of Finance and Administration. Nothing herein shall prevent the requirement of such bonds on construction contracts under $50,000 when the circumstances warrant.
B.
Bid security shall be in an amount equal to at least 5% of the amount of the bid.
C.
When the invitation for bids requires security, noncompliance requires that the bid be rejected unless it is determined that the bid fails to comply only in a nonsubstantial manner with the security requirements.
