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 Selection Guidance (PDMSG)

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 in support of Reform VII.
