About S.e.a. Construction LLC
S.e.a. Construction LLC, doing business as Sea Construction LLC, is a Pacific Northwest-based heavy civil engineering and infrastructure restoration contractor operating exclusively as a prime contractor (100% of awards) across multiple federal set-aside categories. Headquartered in Raymond, Washington, the company holds concurrent SBA certifications as an 8(a) Program Participant (expiring January 19, 2030), Economically Disadvantaged Women-Owned Small Business (EDWOSB), Women-Owned Small Business (WOSB), HUBZone Firm, Veteran-Owned Small Business, and Service-Disabled Veteran-Owned Small Business (SDVOSB, expiring January 20, 2027). The company is also Native American-owned and Department of Transportation certified as a Disadvantaged Business Enterprise. Sea Construction competes predominantly under set-aside contracts, with recent awards split between 8(a) sole source, total small business, and other socioeconomic set-asides rather than full-and-open competition.
Sea Construction's work centers on riverine and coastal infrastructure repair, levee and bank stabilization, dam modification, ecosystem restoration, and road maintenance under NAICS 237990 (Other Heavy and Civil Engineering Construction) and related classifications. Representative prime contracts include an $11.995 million total small business award from the U.S. Army Corps of Engineers Seattle District (August 2023) for onsite disposal and fill placement on the Yakima River Union Gap ecosystem restoration project in Yakima, Washington; a $4.298 million total small business contract from the Federal Highway Administration (February 2026) for storm damage repair on Mora Road in Olympic National Park involving bank stabilization, riprap placement, and engineered log jams; and a $3.081 million 8(a) sole source award from the Army Corps of Engineers (December 2024) for the FY23 Quillayute Rialto Revetment Repair project near Seattle. The company also holds a $49 million, ten-year Blanket Purchase Agreement with the Forest Service Pacific Northwest Region (July 2023 through June 2033) for road maintenance services including asphalt paving, grading, culvert replacement, and debris removal across Oregon, Washington, and Northern California.
Customer concentration skews heavily toward the Army Corps of Engineers and the Forest Service. The top five funding entities account for 78% of recent awards by count but 94% by combined potential value, with the Forest Service Pacific Northwest Region anchoring $50.3 million (the BPA ceiling), the Army Corps of Engineers at $39.2 million across seven awards, the Corps' Seattle District at $16.5 million across eight awards, and the Federal Highway Administration at $6.1 million. The dollar-value rankings diverge noticeably — the Forest Service's single BPA dominates the potential-value picture despite representing only one award, while the Corps' Seattle District places many smaller definitive contracts. Recent activity shows variability: two awards in 2020, six in 2023, three in 2024, two in 2025, and one in 2026. Combined potential value across all 32 prime awards stands at $126.2 million with $71.1 million obligated to date (56% realization). Only one award ($4.3 million, the Mora Road contract completing October 29, 2026) reaches ultimate completion within the next twenty-four months, indicating limited near-term recompete exposure. Sea Construction operates entirely as a prime and carries no subcontract footprint in the award record.
