Contracting staff

About this agency

The Department of the Army Corps of Engineers Seattle District is a sub-agency of the U.S. Army Corps of Engineers responsible for civil-works infrastructure and water-resource management across the Pacific Northwest, procuring engineering, construction, real estate, and specialized services to support hydroelectric operations, dam safety, flood control, environmental stewardship, and military facility projects across its regional footprint.

The District has awarded 9,124 federal contracts worth a combined $8.27 billion in potential value since 1997, with $8.83 billion obligated across the portfolio. Recent activity shows 138 awards in 2022, 129 in 2023, 85 in 2024, 99 in 2025, and 131 year-to-date in 2026, with the most recently recorded award dated September 21, 2026. The District works with 2,581 distinct prime contractors across its history. Competitive concentration is fragmented: the top five primes by award count hold 18 percent of recent awards, led by Bristol Prime Contractors LLC (32 awards, $52.7 million), Veterans Northwest Construction LLC (23 awards, $24.9 million), and Veterans Construction Coalition LLC (23 awards, $26.9 million), while the top five by potential value hold only 2 percent of combined recent value—Bristol, Jacobs Government Services Company, and Veterans Construction Coalition LLC leading that ranking. A significant portion of recent awards carry no reported potential value, indicating substantial transaction volume through Schedule task orders, BPA calls, and below-threshold purchase orders.

Set-asides are heavily weighted toward unrestricted procurements: 57 percent of awards carry no set-aside designation, while 28 percent are total small-business set-asides. The remaining 15 percent distribute across 8(a) sole source (8 percent), competitive 8(a) (3 percent), HUBZone (2 percent), service-disabled veteran-owned small business (1 percent), and woman-owned small business and other designations (less than 1 percent combined).

The District also operates a grant-making function, though at considerably smaller scale. It has awarded 22 federal grants totaling $12.9 million obligated since 2019, with 1 award in 2022, 4 in 2023, 2 in 2024, 6 in 2025, and 4 year-to-date in 2026. The most recent grant award closed May 1, 2026. All 22 grants are structured as cooperative agreements. The five recipients are highly concentrated: The Student Conservation Association Inc. received 11 awards worth $778 thousand; Ecostudies Institute received 1 award worth $5.6 million; Makah Indian Tribe and Suquamish Indian Tribe each received 2 awards totaling $3 million and $906 thousand respectively; and The Evergreen State College received 1 award worth $240 thousand. Ecostudies Institute, Makah Indian Tribe, and Suquamish Indian Tribe hold 82 percent of obligated federal dollars, reflecting high concentration on a small recipient base focused on environmental conservation and tribal natural-resource stewardship.

Recent contract opportunities span water-management operations, construction modernization, real estate, and specialized equipment. Current open solicitations include Governor control programming for Libby Dam (due November 2, 2026; total small-business set-aside), meteorological and hydrological forecasts for western Washington and northwest Montana basins (pre-solicitation, sole source to Upstream Tech), conversion of Joint Base Lewis-McChord barracks to operational facilities (due November 30, 2026; total small-business set-aside), NPDES laboratory services at Chief Joseph Dam (due October 22, 2026, with amendments issued October 16 and October 20; unrestricted), and a $300 million Facilities Sustainment, Restoration, and Modernization IDIQ at Joint Base Lewis-McChord (sources-sought pre-solicitation due September 20, 2026). The District is actively conducting market research and industry days on potential Other Transaction Authority vehicles for large facilities programs, particularly the Sentinel Utility Infrastructure Improvements at Malmstrom Air Force Base and the JBLM FSRM program, signaling intent to move beyond traditional FAR-based contracting on forthcoming multi-year, multi-award frameworks.
