This is a project manual document prepared by the Port of Tacoma for maintenance dredging services at Piers 3 and 4 and Washington United Terminals (WUT) in Tacoma, Washington. The project involves dredging operations to remove high spots that impair berthing capabilities at these port facilities. Dredge material is to be disposed of at the Commencement Bay open-water dredge material disposal site, with debris directed to upland disposal areas. The project encompasses sediment removal and associated debris management to restore full operational depth at the specified pier locations.

The manual provides technical specifications, environmental compliance requirements, and operational procedures for executing the maintenance dredging work. The document establishes standards for sediment characterization, disposal site protocols, and contractor performance requirements. Project execution must comply with applicable environmental regulations governing marine dredging operations in Commencement Bay and address any contamination protocols identified during site surveys. The work is anticipated to be completed within a defined timeframe, with costs to be established through the competitive bidding process managed by the Port of Tacoma.
