Sealaska Constructors LLC

Sealaska Constructors LLC, a subsidiary of Sealaska Corporation (a Tlingit, Haida, and Tsimshian Alaska Native Corporation), delivers federal construction, renovation, design-build, and facility infrastructure services as a prime contractor exclusively under Alaska Native Corporation and small business set-asides. The company operates as a minority-owned, self-certified small disadvantaged business and Indian Economic Enterprise, competing predominantly across Total Small Business, Indian Small Business Economic Enterprise, and Indian Economic Enterprise set-aside categories.

The vendor's customer concentration is heavily concentrated in the Department of the Interior's Bureau of Indian Affairs and related Interior bureaus, which account for 70% of recent awards and 93% of combined potential value. The Bureau of Indian Affairs Central Office alone anchors 30 awards worth $2.31 billion combined potential value, followed by the Air Force Space Command (8 awards, $291.6 million), the Fish and Wildlife Service Region 9 headquarters ($250 million single multiple-award MATOC), the Army Corps of Engineers Seattle District (4 awards, $110.2 million), and the Air National Guard (15 awards, $96.4 million). The concentration is extreme: Interior agencies account for approximately $2.6 billion of the $3.29 billion combined potential value across all 122 awards in the recent portfolio.

Sealaska Constructors operates across seven named indefinite delivery vehicles totaling over $3.2 billion in aggregate ceiling value: the $1.5 billion DOI Construction Multiple Award Contract 2023-2028 set aside for Indian Small Business Economic Enterprises (7 task orders, $95.4 million combined value); a $250 million Fish and Wildlife Service MATOC for alteration, repair, and construction services across the Continental U.S. and Hawaii (January 2022 through December 2026); the $95 million Army Corps of Engineers Seattle District Total Small Business contract for design-build and design-bid-build projects in the Pacific Northwest (March 2023 through February 2028, with recent task orders including a $10.4 million HVAC repair at Lewis-McChord awarded October 2025 and a $3.16 million building modification order awarded September 2024); a $50 million Air National Guard Total Small Business multiple-award IDC for five-year construction services (May 2024 through November 2029); the $53 million BIA Navajo Region Construction MATOC (September 2021 through September 2026, with 10 task orders generating $19.7 million combined value); and two $40 million BIA regional MATOCs covering the Great Plains Region and Northwest Region, each set aside for Indian-owned small business economic enterprises. Representative delivery-order work includes a $73 million design-build contract for the Tonalea Day School in Arizona (awarded September 2023 under the DOI Construction MAC, with ultimate completion June 2028); an $8.48 million plumbing work delivery order for the Warm Springs Detention Center Rehabilitation Center in Oregon (July 2024, Indian SBEE set-aside); a $7.69 million fire suppression, security, and surveillance construction project in Forsyth, Montana for the Bureau of Indian Affairs Great Plains Region (September 2025); and a $7.2 million building rehabilitation order at Vandenberg Space Force Base in California (January 2023 under the VELA Multiple Award Construction Contract, with completion July 2026).

Recent activity has decelerated after a peak in 2022 (19 awards) and 2023 (16 awards) to 8 awards in 2024, 10 awards in 2025, and 2 awards in the first half of 2026 through July 1. Twelve awards with a combined potential value of $118.8 million face ultimate completion within the next twenty-four months, creating recompete exposure across the vendor's Interior and Defense portfolio.

Across SCI-reportable service contracts (a subset of total federal services work above the $150,000 threshold), Sealaska Constructors invoiced $20.6 million in FY2022 and $24.9 million in FY2023, with no FTEs or invoicing recorded in FY2024 in the SCI dataset — a reflection of the vendor's primary focus on construction delivery orders rather than labor-hour service contracts. FTE trajectory in SCI shows 12.6 FTEs in FY2022 and 8.0 FTEs in FY2023 across prime records. On government-paid hourly rates for SCI-reportable work, the median ran around $378/hr, with senior labor pricing through $1,509/hr. Across SCI-reportable prime contracts, named subcontractors represent approximately 12% of total contractor hours, with 26 named subcontractors engaged over the period. The vendor primarily builds its own delivery teams but engages specialized trades — HVAC, electrical, plumbing, roofing, concrete, architectural design, and environmental remediation — through subcontractors on large-scale facility projects.

The vendor's work spans commercial and institutional building construction (105 awards in recent NAICS categorization), with PSC concentration in miscellaneous building construction (26 awards) and repair or alteration of administrative facilities and service buildings (20 awards). Sealaska Constructors operates 100% as a prime contractor across the portfolio; no subcontract awards appear in the source data. The company maintains multiple significant indefinite delivery positions across Interior and Defense agencies, positioning it as an anchored supplier for federal Indian affairs facility infrastructure, military base construction and renovation, and Fish and Wildlife Service refuge system improvements across Alaska, the Pacific Northwest, the Great Plains, the Navajo Nation region, and dispersed Interior facilities nationwide.
