WSF's terminal engineering maintenance group contracts out approximately $2 million in construction projects annually. These contracts address short-term maintenance issues identified through inspections of the facilities, prior to larger replacement projects.
Why is WSDOT Ferries Division (WSF) doing this work?
The goal of these terminal maintenance contracts is to maintain our terminals so that we can prevent disruption to ferry service. These contracts can be broken down into the following categories of work (see diagrams at top right for visuals of terminal structures and components):
- Landing aids: This work involves repairing and replacing fenders, chains, rub faces and piling. All of these items are part of the wingwalls and dolphins against which the vessels land.
- Vehicle transfer spans: This work involves repairing all of the transfer span components, which consist of aprons, towers, bridge seats, and mechanical and electrical systems. This work does not include paving or painting the spans.
- Overhead loading: This work involves repairing the overhead loading structures, which consist of fixed walkways, foundations, electrical and mechanical systems, the elevator cabs and the overhead loading transfer span. This work does not include painting and other items which are included in facility work.
- Painting: Painting all steel around the terminals, including piling, transfer spans, overhead loading and landing aids.
- Trestle and bulkheads: This work includes repairs to the trestles, which consist of piling, caps, stringers, cross bracing, decking and concrete. This also includes work on the bulkheads and the rip-rap that protects the bulkheads.
- Facilities: This involves work all around the facilities and includes utilities, building systems, painting (other than structural steel), and septic systems.
- Pavement: This work involves grading, paving, asphalt sealing and overlays on the bridge decks.
- Vendor work: All of this work is done by purchase requisitions and agreements, and involves preventative maintenance items (typically less than $10,000 each). The major types of work that may be done by vendors include bird deterrent systems; cleaning; maintenance on the compactors and elevators; fender purchases; fire systems; heating, ventilation and air conditioning systems; inspection permits; landscaping; equipment rentals; towing; signing; and striping.
The end result
Our terminals must be in good working order so that we can meet each scheduled sailing and not impose load (weight) restrictions. This is reported as part of WSF's performance measures. Eight of WSF's terminals have more than one slip, which minimizes service disruptions when work is occurring on other slips. However, WSF typically ties up vessels in these slips each night. To prevent the cost of moving vessels each day, these slips need to be operational as much as possible.
The goal of the terminal maintenance team is to prevent lost trips due to terminal issues such as these whenever possible.
This work will maintain our ferry terminals at a standard where we can maintain safe and consistent ferry service to our customers.
What is the project timeline?
Various projects are conducted throughout the year based on terminal availability, weather, and permit restrictions.
WSF has developed an on-call contract for off-shore repairs that require a floating derrick barge. WSF solicits bids for this on-call contract every two years. Once awarded to a contractor, the work is completed on an as-needed basis. This saves a significant amount of time and money by not having to develop separate contracts for each minor item of work.
WSF also solicits bids for an on-call contract for painting work.
Other contract work is designed and bid out for private contractors.
- Budget: $2 million-$2.5 million per fiscal year
- Funding source: terminal engineering maintenance operating funds
