About the company
Seamair Construction, Inc., doing business as Seamair General Engineering, is an SBA 8(a) certified Hispanic American-owned and minority-owned small disadvantaged business that delivers construction, engineering, and facility maintenance services to federal agencies as a prime contractor (92% of recent awards), with a $24.5 million footprint across 25 awards since early 2023. The San Luis Obispo, California-based firm operates under a Subchapter S corporation structure with 8(a) certification extending through June 2031 and competes predominantly under 8(a) sole-source set-asides, which account for the majority of its prime work.
Seamair's capability portfolio centers on emergency infrastructure repair, facility systems maintenance, and construction at federal installations. Representative work includes a $3.16 million 8(a) sole-source HVAC repair contract with Air Force Space Command at Lompoc, California (awarded May 2026); a $3.5 million Army Corps of Engineers erosion mitigation project at Corona, California involving riprap swale and control structure installation (October 2025); and a $3.04 million Honda Ridge retaining wall construction contract at Vandenberg Space Force Base under a Total Small Business set-aside (April 2024). The firm also executes smaller-dollar emergency response work — pump and valve replacement ($34 thousand), plumbing repairs ($50 thousand), and facility systems restoration across Bureau of Prisons locations and Department of Defense installations in California.
Customer concentration tilts heavily toward the Army Corps of Engineers Engineering District Los Angeles, which accounts for 6 awards worth $11.3 million combined potential value (46% of the total footprint by dollars). The top five customer agencies by potential value cover 90% of combined award value: Air Mobility Command ($5 million on a single basic ordering agreement awarded August 2025), Air Force Space Command ($4 million across three awards), Bureau of Reclamation ($1.1 million), and the National Interagency Fire Center ($750 thousand). By award count, the Corps of Engineers leads with six awards, followed by Bureau of Prisons Terminal Island (three awards), Air Force Space Command (three awards), and two smaller customers. The distribution signals a secondary focus on Bureau of Prisons emergency response work (four awards, $647 thousand combined) across multiple correctional facilities in California.
Seamair's parent vehicle footprint includes two Army Corps of Engineers indefinite delivery contracts with $2 million ceilings each (both 8(a) sole source, awarded August 2023 and September 2023), a $5 million basic ordering agreement with Air Mobility Command (no set-aside, awarded August 2025), a $500 thousand multiple-award IDIQ with the National Interagency Fire Center for heavy equipment support in wildland fire suppression regions 5 and 6 (awarded February 2026), and a $250 thousand USDA Forest Service VIPR I-BPA for the same mission set. Seamair also holds a position on the 2019 Vandenberg Air Force Base SABER IDIQ. These vehicles enable task-order issuance without full competition and position Seamair for sustained access to facility maintenance, construction, and emergency-response work across military installations and federal agencies in the western United States.
Activity trajectory shows volatility: eleven awards in 2023, declining to four in 2024, then recovering to five in 2025 and five in 2026 (through mid-July). Three awards totaling $9.8 million in combined potential value reach ultimate completion within the next twenty-four months, creating near-term recompete exposure concentrated in Corps of Engineers work ($3.05 million Honda Ridge retaining wall contract completion March 2027) and Air Force Space Command HVAC repair ($3.16 million, completion October 2027).
Service Contract Inventory reporting shows zero invoiced revenue and zero FTEs in both FY2024 and FY2025 — a signal that Seamair's federal work is predominantly construction and product delivery (goods, equipment, materials) rather than time-and-materials labor services above the $150 thousand SCI reporting threshold. SCI does not capture the firm's total federal revenue, which the award data indicates runs to roughly $21.2 million in obligations across recent years.
Seamair operates predominantly as a prime contractor and does not rely on subcontractors for core delivery. Recent sub-award work includes demolition, earthwork, and utility installation on a Korte Construction Company contract for the GBSD Consolidated Maintenance Facility at Vandenberg Space Force Base (June 2024) and guardrail and drainage repair on a SJD&B, Inc. contract at Honda Ridge Road, Vandenberg Space Force Base (September 2023). The firm maintains a subsidiary, Seamair - Newton JV, LLC, a self-certified small disadvantaged business joint venture.
Seamair's competitive posture is anchored to 8(a) set-asides and small business reservations; full-and-open awards are limited (three of 25 total). The firm has not competed on government-wide acquisition contracts or civilian-agency GSA Schedules and maintains no presence on agencies' incumbent contract renewals outside its Army Corps and Air Force relationships. Geographic concentration in California, particularly around Lompoc, Vandenberg Space Force Base, and correctional facilities in southern California, reflects both Seamair's regional operational base and customer proximity to its San Luis Obispo headquarters.
