Find information on the method in which one-entity - a design-build team, works under a single contract to provide both design and construction services of a project.

Design-build is a method of project delivery in which WSDOT executes a single contract with one entity (the design-builder) for design and construction services to provide a finished product.

The Joint Transportation Committee (JTC) of the Washington State Legislature engaged a team to study the Washington State Department of Transportation’s (WSDOT) use of the design-build (DB) project delivery method. The primary objective of the study was to identify potential changes in law, practice, organizational structure, or policy that will allow WSDOT to optimally employ DB delivery to maximize efficiencies in cost and schedule.
