About Seamair Construction, Inc.
Seamair Construction, Inc., doing business as Seamair General Engineering, is a San Luis Obispo, California-based SBA 8(a) certified Hispanic American-owned and minority-owned small disadvantaged business that delivers construction, engineering, and emergency facility maintenance services to federal agencies as a prime contractor (91% of recent awards) and occasionally as a subcontractor. The firm operates as a Subchapter S corporation and holds 8(a) certification through June 2031.
Seamair's capability portfolio centers on emergency infrastructure repair, facility maintenance, and construction at federal installations across California. Representative prime work includes a $3.5 million Army Corps of Engineers definitive contract (October 2025, 8(a) sole source) for erosion mitigation at Corona, California involving vegetation-free zone establishment, riprap swale construction, and environmental controls; a $3.04 million Army Corps of Engineers definitive contract (April 2024, total small business set-aside) for Honda Ridge retaining wall construction at Vandenberg Space Force Base with concrete drilled piers and steel tie rods; a $5 million Basic Ordering Agreement with Air Mobility Command (August 2025) for facility maintenance and infrastructure services through August 2030; and a $824,750 Air Force Space Command definitive contract (August 2025, 8(a) sole source) for boiler room HVAC repair at Lompoc. Seamair also holds a $250,000 National Interagency Fire Center indefinite delivery contract (February 2026, total small business set-aside) for heavy equipment (dozers, excavators) supporting wildland fire suppression in Regions 5 and 6. Emergency work spans plumbing repairs, water line rupture response, gas line repairs, roof replacement, fence installation, and structural shoring at federal correctional institutions and other installations.
Customer concentration sits heavily with the Army Corps of Engineers Engineering District Los Angeles, which accounts for 6 awards worth $11.3 million (54% of combined potential value). The Department of the Interior Bureau of Reclamation, Department of the Air Force (Air Mobility Command and Space Command), and Department of Justice Bureau of Prisons facilities (Terminal Island, Dublin, Herlong, Lompoc, and Complex Lompoc) form the remainder of the active customer base. Across 12 distinct agencies, the top five customers by potential value represent 89% of combined potential dollars.
Activity shows contraction: 11 awards in 2023 declining to 3 awards in 2026 year-to-date. Combined potential value across all awards reaches $21 million with $18 million obligated. Five awards valued at $8.9 million reach ultimate completion within the next twenty-four months, presenting recompete exposure for the vendor. Seamair subcontracts occasionally; recent sub work includes demolition, earthwork, and utility support under Korte Construction Company on a GBSD Consolidated Maintenance Facility modification at Vandenberg Space Force Base (June 2024) and guardrail and drainage repair under SJD&B, Inc. at Honda Ridge Road on Vandenberg (September 2023). The firm holds a named subsidiary, Seamair - Newton JV, LLC, certified as a small disadvantaged business joint venture.
