On Nov. 3, Washington State Ferries (WSF) submitted an application to a statewide committee responsible for approving the use of alternative public works contracting procedures. WSF selected General Contractor / Construction Manager (GC/CM) as the delivery method best suited to address the unique characteristics of the project. For details on the review and approval process, visit the PRC website.
WSF plans to start the procurement process for the GC/CM in early 2015, pending approval from the statewide committee. In advance, industry partners and interested parties are invited to review the draft Request for Proposals (RFP) and provide comments by Dec. 19. WSF will also host an informational meeting at 1 p.m. on Monday, Dec. 15, on the fifth floor of the WSF Headquarters located at 2900 Third Avenue in Seattle.
Washington State Ferries (WSF), the Federal Highway Administration (FHWA), and the Federal Transit Administration (FTA) are planning a project to replace the aging and seismically vulnerable components of Colman Dock in Seattle in order to maintain ferry service in the future.
Why is WSDOT
considering replacing the Seattle Ferry Terminal?
Colman Dock in Seattle is WSF’s largest ferry terminal and supports transportation across Puget Sound between downtown Seattle and communities in Kitsap County. It serves general and commercial purpose traffic, high occupancy vehicles, transit, bicyclists and pedestrians. In 2013 alone, Colman Dock served over 8.5 million riders, including 4.4 million foot passengers. The Seattle/Bainbridge route is WSF’s busiest passenger route and has the largest annual ridership. By 2030, overall ridership is projected to increase by 39 percent for the Seattle/Bainbridge route and by 25 percent for the Seattle/Bremerton route.
The project’s purpose is to preserve the transportation function of an aging, deteriorating and seismically-deficient facility to continue providing safe and reliable service. The project will also address existing safety concerns related to conflicts between vehicles and pedestrian traffic and operational inefficiencies.
Key project elements include:
- Replacing and re-configuring the timber trestle portion of the dock;
- Replacing the main terminal building;
- Reconfiguring the dock layout to provide safer and more efficient operations;
- Replacing the vehicle transfer span and the overhead loading structures of Slip 3;
- Replacing vessel landing aids;
- Maintaining a connection to the Marion Street pedestrian overpass;
- Replacing the passenger-only ferry facility on southern edge of Colman Dock with local funding from King County
- Mitigating for additional 5,200 square feet of overwater coverage
- Capping existing contaminated sediments
The End Result
The new Seattle Multimodal Terminal at Colman Dock will improve safety by addressing safety concerns related to seismic vulnerability and conflicts between vehicle, bicycles and pedestrians. While avoidance and minimization of new overwater coverage was a key goal of the project, the new facility will increase the overwater footprint by approximately 5,200ft2 Mitigation for this increase in overwater coverage would include restoration of equivalent ecological functions in Elliott Bay or elsewhere in Puget Sound.
WSF, FTA and FHWA will continue to coordinate closely with other Seattle waterfront projects, including the Elliott Bay Seawall Replacement project, Waterfront Seattle program, and Alaskan Way Viaduct Replacement Program throughout the design process.
The project would:
- Ensure that the Colman Dock facility can continue to provide, safe, reliable and efficient ferry service between Seattle and Kitsap County;
- Improve safety by addressing seismic vulnerability and reducing conflicts between vehicles and pedestrians;
- Improve existing pedestrian connections to local transit service;
- Upgrade terminal facilities to current codes and regulations, including the Americans with Disabilities Act (ADA);
- Remove large quantities of creosote-treated timber piles from Elliott Bay;
- Open up an area of shoreline and near-shore habitat;
- Provide stormwater treatment for all new and replaced areas of the trestle;
- Provide opportunities for remediation of contaminated sediments
What is the project timeline?
- 2012-early 2015 – Environmental process/preliminary design
- 2015-2017 – Final design, permitting and procurement
- 2017-2022 – On-site construction
The Legislature has included $268 million for the Seattle Project in their planned capital list, relying on a combination of local, state and federal funding sources. King County is also responsible for securing funding for the replacement passenger-only ferry facility.
- Terminal Building and North Trestle Replacement: $207 million
- Slip 3 Overhead Loading and Transfer Span Replacement: $48 million
- Passenger-only Ferry Facility Replacement: $13 million, to be provided by King County
