Pre-Solicitation - FY26-FY29 Grays Harbor Inner Harbor Maintenance Dredging
This is a pre-solicitation notice for a large, multi-year maintenance dredging project in Grays Harbor, Washington, with an estimated construction magnitude of over $10 million. The work involves mechanically dredging approximately 1 million cubic yards of sediment per season over three consecutive dredging seasons, scheduled between July 2026 and February 2029. Annual work must occur within the approved in-water window from July 16 through February 14, with a mandatory seasonal shutdown typically from late September through December 1 to accommodate Tribal fishing. Dredging will take place in specific channel reaches within the inner harbor, and dredged material will be transported for disposal at one of two designated sites, depending on the time of year. The contract will be a Firm-Fixed-Price award to the lowest responsive bidder, and the contractor must comply with all environmental monitoring and work restrictions.
