This study investigates and compares the costs, benefits, and risks associated with the Design-Bid-Build, Design-Build, and Construction Manager/General Contractor project delivery systems, as well as those related to use of early completion incentives/disincentives (I/D). The scope of the study covers various types, sizes, and scopes of transportation projects delivered by State highway agencies. The study involves collecting, organizing, and analyzing data from various highway agencies. The research product is guidance for State highway agencies to assist them in determining when to use each of the various project delivery systems to realize maximum benefit with regard to cost, benefits, and risk, as well as to determine appropriate incentive/disincentive levels for completion time.
The key project objectives are:
(1) Document the benefits, costs, and risks associated with projects delivered under Design-Bid-Build, Design-Build, and Construction Manager/General Contractor systems.
(2) Quantify the cost, schedule, and quality consequences of using alternative delivery systems on appropriate projects.
(3) Document the benefits, costs, and risks associated with use of completion time incentives/disincentives (I/D).
(4) Provide State highway agencies with guidance on determining when to use each of the project delivery systems to realize maximum benefits with regards to project type, size, and complexity.
(5) Provide State highway agencies with a sound, systematic process for determining incentive/disincentive amounts and times.
