About the company
Northwest Hydraulic Consultants Inc. Seattle Division, doing business as Northwest Hydraulic Consultant Inc., is a foreign-owned subsidiary of Canada-based Northwest Hydraulic Consultants LTD that delivers civil engineering and hydrologic consulting services to federal agencies predominantly as a prime contractor (98% of recent awards), with a secondary footprint of subcontract work under major primes including Jacobs Engineering Group Inc.
The vendor operates out of Tukwila, Washington and serves as a prime recipient on federal grant programs and holds seats on multiple Army Corps of Engineers indefinite delivery contracts. The corporate structure places the Seattle division as a child entity of the Edmonton, Alberta parent; the parent holds federal prime contract awards while the Seattle division generates the bulk of federal work. Capability concentration runs heavily toward civil engineering and water resources consulting — engineering services account for 51 recent awards, with architect-and-engineering PSC codes dominating the portfolio at 99 awards in landscaping and site design and 37 in marine engineering, supplemented by water-quality studies and hydrologic analysis.
Customer concentration centers on the Army Corps of Engineers. The top five customer agencies account for 76% of awards by count and 82% by combined potential value. The Department of the Army Corps of Engineers as a whole accounts for 80 awards; the Army Corps of Engineers Engineering District Seattle (a subordinate command) anchors the dollar picture with 12 awards worth $6.4 million in combined potential value. Federal Emergency Management Agency (14 awards, $2.7 million) and the Department of the Army proper (36 awards) round out the active set.
The vendor operates across five named Army Corps indefinite delivery contracts. The largest is EMS2001CO0067, with 35 task orders carrying $4.4 million in combined potential value. DACW5791D0012 has generated 13 task orders; DACW0502D0012 carries 10 task orders and $580 thousand combined potential value; DACW0599D0015 has 9 task orders; and DACW5796D0016 has 8. Recent subcontract work includes erosion control and water supply studies performed under Jacobs Engineering on Lower Snake River and Lower American River projects. Activity remains modest — two awards in 2024 and two in 2025 — against a historical footprint spanning from 1983, with combined obligated dollars of $16.6 million against $11.8 million in combined potential value across all 202 awards in the source data.
