  • A+B Bidding

    1. A method of rewarding a contractor for completing a project as quickly as possible. By providing a cost for each working day, the contract combines the cost to perform the work (“A” component) with the cost of the impact to the public (“B” component) to provide the lowest cost to the public. 2. A cost-plus-time bidding procedure. The low bidder is selected based on a combination of the traditional contract unit price items-based bid (A) and the time component proposed by the bidder to complete the project or a critical portion of the project (B).
