• Bid Bond is used in conjunction with construction bidding processes. The deposit serves as a guarantee that, in the event that a contract is awarded on the basis of a submitted bid, the contractor will enter into a contract to perform the work at the specified price. If the contractor refuses to enter into a contract to perform work at the agreed price, the security bond reimburses the creditor (owner or superior contractor) for the difference between the non-performing contractor’s bid and the next lowest bid up to the penalty amount of the bond.
