MethodsTypes of Processes

– A+B Bidding• A+B bidding reduces contract time on

projects• Contractors bid the time to complete the

project and a dollar amount for work items• The contract is awarded to the lowest

combination of time and cost.

– Lane-Rental• Lane-rental reduces impacts to the

traveling public by minimizing the time lanes are closed

• Contractors are charged a fee for closing lanes and shoulders due to construction activities

• The concept focuses on the time that the public is affected, NOT the overall contract time

– Incentives/Disincentives• The contractor is paid for early completion

of a project as provided for in the contract• If the contractor completes the project

later than the time allowed, disincentive money is subtracted from payments due

– Constructability Reviews• The industry provides valuable feedback

into key areas that the Agency may not be able to quantify during the project development process

• Feedback on preliminary plans has the potential to significantly reduce project costs and construction timelines

– Locked Incentive Date• A locked incentive date provides an

incentive if the contractor completes the work done early

• Contractors are not allowed any extensions in the completion date, regardless if extensions are owner caused or not

– Pay-for-Performance• Pay-for-performance specifications rely on

final outcomes measured against performance criteria set forth in the contract

• If the contractor fails to meet minimum performance criteria, payment is withheld and corrective action is required

– Warranties• Warranties require contractors to

guarantee all or portions of a construction project to be free of defects in materials and workmanship for a period of time

• The contractor is required to correct deficiencies that occur during the warranty period.
