Seattle Public Utilities (SPU), on behalf of Lower Duwamish Waterway Group (LDWG), is requesting proposals from qualified consultant teams to provide program support, construction management, and services related to remedial action and site monitoring for sediment cleanup in the Lower Duwamish Waterway (LDW) Superfund/CERCLA Site. LDWG, consisting of the City of Seattle, King County, and Boeing, has been partnering to conduct remedial investigation and design for the clean-up of contaminated sediments in the LDW Superfund Site in Seattle, Washington. The United States Environmental Protection Agency (EPA) issued the Selected Remedy for the LDW site in 2014 in their Record of Decision (ROD) and will provide oversight on this project.

Cleanup will begin upstream (south) in the upper reach and move downstream. Services under this contract will support the project design and construction phases, which are expected to extend from contract execution through approximately 2034. The estimated contract value is $40 million for all phases. SPU expects to issue 3 or more Work Assignments iteratively over the course of the contract with varying dates for milestones and deliverables depending on the scope. Each Work Assignment will be executed for a period of approximately three (3) years with the option to extend. SPU does not guarantee any minimum quantity of Work under this contract.
