About this award
The U.S. Army Corps of Engineers Seattle District awarded a $1.4 million firm fixed-price definitive contract to Duwamish Services LLC, a Seattle-based SBA Certified HUBZone firm and Small Disadvantaged Business, for maintenance hydraulic dredging of the Quillayute River Federal navigation channel in La Push, Washington. The contract, awarded on July 7, 2025, with an ultimate completion date of March 30, 2026, encompasses dredging of the outer and inner channels, access lanes, and boat basin, with dredged materials placed in defined areas during specified in-water work windows between September 2025 and March 2026. The procurement was designated as a Total Small Business set-aside under NAICS code 237990 and required careful coordination with the Quileute Tribal Reservation and tribal fishing activities.
Duwamish Services LLC has demonstrated substantial expertise in marine construction and dredging operations for federal agencies, with three significant prime contract awards totaling approximately $5.65 million. Beyond this Quillayute River award, the company recently secured a $1.9 million Army Corps of Engineers contract for Snohomish River dredging and previously completed a $2.35 million Department of the Interior Fish and Wildlife Service armor rock procurement and placement project for seawall repair at Midway Atoll National Wildlife Refuge. The contractor's established capabilities in hydraulic dredging, material procurement, and specialized marine infrastructure work position it to execute the complex environmental and waterway maintenance requirements of this Pacific Northwest navigation channel project.
