About the company
Sea-Tech Advanced Restoration Solutions, an SBA 8(a) certified joint venture based in Richland, Washington, delivers environmental remediation and subsurface removal services to federal agencies as a prime contractor, competing exclusively under 8(a) sole-source set-asides. Sea-Tech is a minority-owned, Native American-owned, Alaskan Native Corporation-affiliated small business structured as a partnership or limited liability partnership, and operates as a wholly owned subsidiary of Sealaska Government Services, LLC, itself an Alaskan Native Corporation that holds federal contract vehicle authority.
Sea-Tech's federal footprint remains narrow but dollar-dense. The vendor has received three awards totaling $18.3 million in combined potential value (with $6.2 million obligated to date), split evenly between the Department of the Navy Naval Facilities Engineering Command and the Department of the Army Corps of Engineers. On the Navy side, Sea-Tech holds a $4.5 million single-award Indefinite Delivery Contract running through September 2030 for long-term management and remedial action operations at the Bethpage Naval Weapons Industrial Reserve Plant in New York; the initial delivery order against that IDC, valued at $3.8 million on a firm fixed-price basis and awarded September 25, 2025, covers interim treatment system operations at Bethpage through September 2028. The second Navy award is a separate delivery order for the same site ($3.8 million, 8(a) sole source). On the Army side, the National Nuclear Security Administration awarded a $10 million definitive cost-plus-fixed-fee contract on June 2, 2026, for slab and subsurface removal at Lawrence Livermore National Laboratory Building 280 in Livermore, California, with completion targeted for June 2028. Activity has been recent and concentrated — two awards in 2025 and one in 2026 — with $13.8 million in combined potential value facing ultimate completion within the next twenty-four months, exposing Sea-Tech to significant recompete risk across its entire active base. Sea-Tech operates exclusively as a prime and has placed no subcontract work in the source data. The vendor's capability profile centers on environmental remediation, interim treatment system operations, and subsurface engineering at federal facilities, with customer concentration split between Navy facilities environmental management and Army laboratory site restoration.
