– 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.

MethodsTypes of Processes
– 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

MethodsTypes of Processes
– 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

– 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.
