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 following contracts will be advertised in 2010:
How does the contracting process work?
When these contracts are advertised they will be posted on WSDOT's Contract Ad and Award Web site. The selected contractors will be responsible for securing vendors and sub-contractors, and assembling their workforce. WSDOT will work with contractors to ensure that notification is provided to all potential parties, and have added contact information to this list of interested parties.
Are there apprenticeship requirements?
The design-builder will comply with an apprentice utilization requirement. It is anticipated that no less than 15 percent of project labor hours will be performed by apprentices. The apprenticeship program provides on-the-job training and supportive services to assist contractors with recruitment and placement of minorities and women, as well as to provide advocacy and support for individual apprentices/trainees participating in the program.
WSDOT is responsible for road maintenance, environmental protection, long-term planning and project design. Contractors hired by WSDOT complete construction projects and hire administrative and field staff to work on those projects.
WSDOT advertises projects on the Contract Ad and Award Web site. At this Web site, contractors can view projects that are available for bid, learn about pre-qualifications, and stay up-to-date with contractor bulletins.
