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.

Project Delivery Method Selection Guidance (PDMSG) was developed to aid WSDOT staff in evaluating projects for the most appropriate Project Delivery Method (PDM) based on each project’s attributes, opportunities and risks that result in the most cost effective and best value project delivery.

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.
