Keeping 10 Million Annual Passengers Moving During the Renovation of Washington's Busiest Ferry Terminal

Seattle Multimodal Terminal at Colman Dock

Hoffman’s preconstruction planning and proven safety and “no disruption” protocols are showcased as we transform Puget Sound’s busiest ferry terminal, performing complex construction while maintaining service to more than 10 million passengers a year.

Hoffman, in a joint venture with Pacific Pile & Marine, is continuing work on this massive $291 million GC/CM renovation of Colman Dock, the busiest ferry terminal in Washington and one of the busiest in the world. To maintain Colman Dock’s critical role as a regional multimodal transportation hub, the team is replacing aging and seismically vulnerable wood piles and trestle foundation with steel for strength and longevity and is demolishing and replacing the ferry terminal and passenger facilities.

Scheduled for completion in 2023, the project will add an Overhead Loading and Walkway, an 8,500 SF King County Passenger-Only Ferry Building, and a new 23,000 SF Terminal Building for Washington State Ferries, with LEED Silver certification.


How do you keep 10 million passengers per year flowing in and around an active construction jobsite?


The Hoffman team performed extensive preconstruction planning to develop comprehensive safety and “no disruption” phasing plans for the busy terminal.
