For all construction contracts estimated to exceed one hundred thousand dollars ($100,000), the CCO shall require bid security in the form of a bond, cash or other acceptable form of bid security outlined in the solicitation document. All bonding companies must be licensed to conduct business in the District of Columbia and must be included on the Department of Treasury's Listing of Approved Sureties.
If a bidder that has furnished bid security in a form other than a bond is awarded a contract and fails to post a payment and performance bond for the full value of the contract, the bidder shall forfeit the full amount of the bid security provided.
Bid security shall be in amount equal to not less than five percent (5%) of the estimated cost of the contract to be awarded pursuant to the procurement.
For all construction contracts awarded in excess of one hundred thousand dollars ($100,000), the CCO shall require that the contractor provide both a payment bond and a performance bond each in an amount equal to one hundred percent (100%) of the contract price. All such bonds shall be issued by bonding companies licensed to conduct business in the District of Columbia and included on the Department of Treasury's Listing of Approved Sureties. The CCO, in its reasonable discretion, may reduce the value of the payment bond and performance bond required, however, the value of each may not be reduced to less than fifty percent (50%) of the contract price.
The Contracting Officer may, in his or her reasonable discretion, require additional forms of security as set forth in section 704 of the PPRA.
