SR 520 Bridge Replacement and HOV Program - Contractor information

What is WSDOT's contracting process?

WSDOT hires contractors to complete construction projects. The contractor is responsible for hiring administrative and field staff to work on those projects. The contractors also are responsible for securing vendors and subcontractors for the projects, and assembling their workforce. WSDOT works with the contractors to ensure that notification is provided to all potential parties.

Montlake Project contracting opportunities

We announced Oct. 10 that Graham Contracting Ltd. submitted the contract proposal with the apparent best value for the upcoming Montlake Project. Read more about it in our recent news release. The Montlake Project is scheduled to begin construction in early 2019.

We published a Request for Proposals on Feb. 28 in preparation for selecting a design-build contractor for the upcoming Montlake Project of SR 520 construction.  Subcontractors and vendors interested in learning more about the RFP will find it on WSDOT’s Contract Ad and Award webpages.

Apprenticeship requirements

Design-build and design-bid-build teams will comply with an apprentice utilization requirement. The goal is that 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.
