Ferry terminal maintenance

Washington State Ferries’ contracts out roughly $3 million in terminal maintenance construction each year. These contracts address short-term issues identified through facility inspections prior to larger replacement projects. We also conduct a large portion of maintenance work with in-house staff and by working with various WSDOT regions.

Proper terminal maintenance helps prevent ferry service disruptions. The contracted work covers the following (see diagrams for visuals of terminal structures and components):

We solicit bids for an on-call contract for offshore repairs that require a floating derrick barge every two years. Once awarded to a contractor, the work is completed on an as-needed basis. We also solicit bids for an on-call contract for painting work. Other contract work is designed and bid out to private contractors.
