Associated Underwater Services, Inc.

Associated Underwater Services, Inc., a woman-owned small business based in Spokane, Washington, operates as a prime contractor providing specialized underwater inspection, diving, and marine infrastructure services to federal water-resource and civilian agencies, predominantly under Total Small Business set-asides. The vendor holds SBA certifications as a Women-Owned Small Business and a Disadvantaged Business Enterprise and competes almost exclusively in set-aside categories across its 137-award footprint.

The company's capability portfolio centers on underwater structural inspection, dive operations, marine infrastructure repair, and debris removal at dams, water control structures, and coastal facilities. Representative recent work includes a $203,530 diving services contract with the Bureau of Reclamation to remove wood debris at Folsom Dam at depths of approximately 173 feet (awarded April 21, 2025), a $240,885 dive inspection services award from the Army Corps of Engineers for the Lake Washington Ship Canal covering approximately 30 structures (awarded March 6, 2024), a $30,243 pipeline replacement order from NOAA at the Northwest Fisheries Science Center in Port Orchard, Washington (awarded March 20, 2026), and a $97,207 purchase order from the Army Corps of Engineers, Northwestern Division, Portland District, to remove a Passive Integrated Transponder interrogation system from Lebanon Dam in Oregon (awarded April 7, 2026). These awards reflect firm fixed-price purchase orders and delivery orders with performance typically completed within months to a few years.

Customer concentration is highly regional and agency-specific. The Army Corps of Engineers Engineering District Walla Walla dominates by award count (77 awards, $4.4 million combined potential value), but the Department of the Interior Bureau of Reclamation anchors the largest dollar share ($11.2 million across five awards). The top five customer agencies account for 80% of recent awards by count and 98% of combined potential value. The Corps of Engineers broadly (combining district and command-level awards) represents $10.7 million across 94 awards, reflecting long-standing relationships across the Pacific Northwest region. NOAA, the National Park Service, and the Coast Guard round out the active customer set.

Associated Underwater Services holds a position on a Reclamation-wide Multiple Award IDIQ for underwater inspection services (valued at $10 million ceiling, awarded September 18, 2025, running through September 30, 2030) and has placed task orders under three Army Corps of Engineers indefinite delivery contracts (W912EF09D0005, W912EF04D0005, and W912EF16D0002, combining 87 task orders with $3.9 million in combined potential value). A delivery order under the Reclamation IDIQ establishes a $2.5 million minimum guarantee and covers inspections of underwater structural components across 17 Western States at variable elevations up to 10,000 feet, with work typically conducted September through April to access seasonal outage periods.

Award activity has accelerated modestly in recent years — two awards annually in 2021–2022, then rising to six in 2025 and three in the first half of 2026 — though the magnitude remains in the low-to-mid hundreds of thousands per order. Only one award (combined potential value $97 thousand) is scheduled for ultimate completion within the next twenty-four months, presenting limited near-term recompete exposure.

The vendor operates nearly exclusively as a prime (97% of awards) and subcontracts minimally. Recent sub work includes a $98 million task order under Central Plateau Cleanup Company's Hanford Central Plateau Cleanup Contract for 400-area internal water tank inspections (April 29, 2026), clean-and-inspect drinking water tanks under Amentum Technology (April 17, 2025), and scientific and engineering support for the Acoustic Research Detachment at Bayview, Idaho, under General Dynamics Information Technology (March 28, 2025 and June 11, 2024). The SCI dataset captures three records total and shows zero invoiced revenue and zero FTEs across FY2022–FY2023 prime contracts, reflecting the vendor's focus on sub-$150,000 purchase orders and micro-purchases outside the SCI reporting threshold.
