Pre-solicitation Notice Number: W912DW26Z1BD9

The magnitude of construction is estimated to be more than $10,000,000.00.

Project Title: FY26-FY29 Grays Harbor Inner Harbor Maintenance Dredging

Project Details: The U.S. Army Corps of Engineers (USACE), Seattle District has a requirement for planned maintenance dredging in Grays Harbor, Washington.

This work is scheduled to be executed over three consecutive dredging seasons between July 2026 and February 2029, as part of the Grays Harbor and Chehalis River Federal Navigation Project.

The Government anticipates awarding a Firm-Fixed-Price (FFP) contract through a competitive Invitation for Bids (IFB) process. Award will be made to the lowest responsive and responsible bidder, in accordance with FAR Part 14 procedures. The selected contractor will be responsible for the mechanical clamshell dredging of approximately 1 million cubic yards (CY) of sediment per season, for each of the three dredging seasons.

Work will occur annually during the approved in-water work window from July 16 through February 14. Dredging activities must be suspended during a mandatory seasonal shutdown period—typically from late September through December 1—to accommodate Tribal fishing activities, the specific dates of which will be provided annually. Dredging will take place within the federally authorized navigation channel, specifically in the following reaches: Aberdeen, Cow Point, Cow Point Turning Basin, Hoquiam North Channel, and the Crossover Channel. These areas encompass the middle portion of the harbor up to and slightly beyond the main Port terminals. Dredged material will be transported via bottom dump barge and placed at one of two disposal sites. From mid-July through early November, material will be placed at the South Jetty Beneficial Placement Site, while from November through mid-February, disposal will shift to the Point Chehalis Open Water Placement Site. All disposal activities must comply with project specifications and environmental guidelines.

Environmental Requirements: The contractor will be required to perform turbidity monitoring during dredging and disposal operations. The contractor will also be responsible for adhering to all in-water work timing restrictions and for suspending operations during the specified Tribal fishing closure window each season.

See the forthcoming solicitation for details about bid submission and virtual bid opening. The
NAICS code for this procurement is 237990, Dredging and Surface Cleanup, and the associated
small business size standard is $37,000,000 in average annual receipts.
