Terminal 10 Utility Infrastructure Upgrade

This marine infrastructure project upgraded the Port of Seattle’s Terminal 10 to be able to be operated as a cargo terminal.  Terminal 10 is now able to support activities including marine related cargo container handling and marshalling, outdoor storage of empty containers and truck chassis, and transshipment of bulk materials. 

The work involved installation of nearly 5,000 feet of pipe along with 50+ stormwater structures.  It involved installation of a 60-foot by 40-foot Cofferdam Cell needed for the installation of two large stormwater treatment vaults.  Crews built new conveyance and treatment systems with a new 30-inch diameter outfall/headwall structure and performed various site demolition and earthwork activities, as well as asphalt paving, striping, pavement marking and installation of security fences, gates and lighting systems.

The work was performed on a restricted jobsite along the busy Port of Seattle waterfront.
