About the company
Associated Underwater Services, Inc., a woman-owned small business headquartered in Spokane, Washington, performs specialized underwater inspection, diving, and marine infrastructure services for federal water-resource and maritime agencies as a prime contractor on 97% of its awards. The company holds SBA Women-Owned Small Business and self-certified small disadvantaged business designations and competes predominantly under Total Small Business set-asides on its prime work.
The vendor's capability portfolio centers on underwater structural inspection, dive operations, equipment removal and installation, and marine infrastructure maintenance at federal dams, water-conveyance systems, ship canals, and research facilities across the Western states. Representative work includes a $10 million multiple-award indefinite-delivery contract awarded by the Bureau of Reclamation in September 2025 for underwater inspection services at dams, bridges, stilling basins, and water control structures across 17 Western states, with seasonal operations September through April at depths up to 173 feet and water temperatures below 40 degrees Fahrenheit; a $240,886 firm fixed-price purchase order from the Army Corps of Engineers Engineering District Seattle in March 2024 for dive inspections at approximately 30 structures in the Lake Washington Ship Canal; and a $203,530 purchase order from the Bureau of Reclamation in April 2025 for five-person dive-crew removal of wood debris obstructing Temperature Control Device shutter panels at Folsom Dam at 173-foot depth. Other representative work includes a $253,250 definitive contract from the National Park Service Pacific West Region in September 2022 to relocate the Echo Bay Barge at Lake Mead National Recreation Area due to water-level drops, a $97,207 purchase order from the Army Corps of Engineers Engineering District Portland in April 2026 for removal of a Passive Integrated Transponder interrogation system from Lebanon Dam, and a $30,244 purchase order from NOAA in March 2026 for pipeline replacement beneath a float platform at the Northwest Fisheries Science Center in Port Orchard, Washington.
Customer concentration is heavily skewed toward the Army Corps of Engineers Engineering District Walla Walla (77 awards, $4.4 million combined potential value) and the broader Department of the Army Corps of Engineers (17 awards, $6.3 million), together accounting for the plurality of award volume; however, the Bureau of Reclamation anchors the largest dollar exposure (6 awards, $11.3 million combined potential value), driven primarily by the September 2025 $10 million IDIQ. The vendor serves 14 distinct customer agencies. The top customers by award count cover 80% of awards; the top customers by potential value cover 98% of combined potential value. The Bureau of Reclamation dominates potential-value rankings, while Walla Walla dominates award count, reflecting the IDIQ structure.
Associated Underwater Services operates three active parent vehicles: indefinite-delivery contracts W912EF09D0005 (32 task orders, $885 thousand combined potential value), W912EF04D0005 (29 task orders, $178 thousand), and W912EF16D0002 (26 task orders, $2.9 million), all issued by the Army Corps of Engineers; a Bureau of Reclamation IDIQ 140R3025D0008 carrying 2 task orders and $83 thousand; and Seaport Next Generation with 2 task orders. The classification breakdown shows 109 awards under NAICS "All Other Support Services," with the plurality of PSC coding concentrated in "Inspection—Miscellaneous" (66 awards) and "Support—Professional: Other" (30 awards).
Activity has accelerated in the past two years—two awards in 2024, six in 2025, and four so far in 2026—following a dormant 2023. Only one award (combined potential value $80 thousand) reaches ultimate completion inside the next twenty-four months, placing minimal recompete pressure in that window. The vendor operates as a subcontractor on approximately 3% of its awards, primarily under General Dynamics Information Technology on acoustic research and operations-support work at the Acoustic Research Detachment in Bayview, Idaho, and under Central Plateau Cleanup Company on Hanford Site water-tank inspections. Service Contract Inventory reporting is sparse: three SCI records across FY2022–FY2024 (two prime, one sub) with zero invoiced revenue captured, reflecting the vendor's concentration on purchase-order and small-contract work below or near the $150,000 SCI threshold and the exclusion of goods and products from SCI scope.
