Find Design-Build Projects

Design-Build is a method to deliver a project in which the design and construction services are contracted by a single entity. Design–build relies on a single point of responsibility, and is used to minimize risks for the WSDOT and to reduce the delivery schedules by overlapping both the design phase and construction phase of a project.

Some of WSDOT’s larger projects are administered through the design-build process. Because these are very large projects, more opportunities exist for subcontractors. Locate more information about current design-build projects and potential bidding opportunities .
