Working from Barges – Seattle’s Colman Dock Project Underway

 

Colman Dock in Seattle is the largest Washington State Ferries terminal and supports transportation across Puget Sound between downtown Seattle and communities in Kitsap County and the Olympic Peninsula. Key components of Colman Dock are aging and vulnerable to seismic events. The layout of today’s facility also creates safety concerns and operational inefficiencies due to conflicts between vehicles, bicycles and pedestrian traffic.

The Washington State Department of Transportation (WSDOT) has undertaken an enormous project to repair the multimodal terminal at Colman Dock without interruption to ferry service.

Key project elements include:

  • Replacing the existing timber trestle portion of the dock with a new concrete and steel trestle
  • Replacing the main terminal building
  • Replacing the passenger-only ferry facility on the south edge of Colman Dock with funding from King County
  • Constructing a new elevated walkway between the terminal building and the passenger-only ferry facility

Construction will continue until 2023 and the terminal will remain open throughout construction. 

Working from barges will help increase space on Colman Dock during construction.  WSDOT notes “Our contractor is using multiple barges at a time to stage construction equipment and huge cranes used to rebuild Colman Dock. Working from the water allows us to reduce our shore side construction zone footprint in every stage of the project. Smaller construction zones mean more room on the dock for vehicle holding.”

For a full description and details, see the WSDOT page dedicated to the project.  More pictures are available on the WSDOT Flickr page, as well.

Seattle, WA Colman Dock Construction Continues

Washington State Ferries is replacing the aging and seismically vulnerable parts of Colman Dock in Seattle in order to maintain its critical role as a regional multimodal transportation hub.

The Washington State Department of Transportation (WSDOT) reported that construction crews recently finished installing all of the concrete panels needed to form the flooring deck of the first section of the new main ferry terminal building at Colman Dock. Next steps include filling in the gaps between the panels to make one smooth trestle deck, this is called a “closure pour.”

This section of the new building will open in mid-2019. At that point, it will be used as the main ferry terminal facility while crews clear out and demolish the old terminal building, the one currently in use. Once the old terminal building is taken down, the remaining sections of the new terminal building will be built. The entire new terminal building and surrounding dock will open to the public in 2023.

The opening date of the new passenger-only ferry building and pier, currently under construction on the south side of Colman Dock, has moved to summer 2019 instead of this fall. The revised opening date allows the contractor to re-sequence the overall construction schedule so that WSDOT can stay on track to finish the entire Seattle Multimodal Terminal at Colman Dock Project on time.
