About the company
General Mechanical Corporation, doing business as Oneida Environmental & Construction (Oneida E&C), is a tribally-owned, SBA-certified 8(a) small disadvantaged business headquartered in Daytona Beach, Florida, that delivers construction, facility renovation, repair, and maintenance services to federal agencies as a prime contractor (100% of recent awards). The company operates under Subchapter S corporation structure and holds two subsidiaries: Gmc-Chc JV LLC and Oneida-Cape JV II LLC, both tribally-owned and SBA-designated small disadvantaged enterprises. Oneida E&C competes predominantly under 8(a) sole-source and total small business set-asides, with recent work spanning facility HVAC replacements, hangar renovations, parking construction, dune restoration, instrument landing system infrastructure, and painting services across military installations and space operations facilities.
Oneida E&C's customer concentration is dominated by space-focused defense and civilian agencies. The Department of the Air Force Space Command anchors the portfolio with 11 awards valued at $757.5 million in combined potential value, representing 83% of total portfolio dollars — substantially driven by the Space Coast Multiple Award Construction Contract (Space Coast MAC), a $750 million Air Force Space Command IDIQ where Oneida E&C holds a prime seat and has issued 10 task orders valued at $7.5 million. The National Aeronautics and Space Administration Kennedy Space Center is the second-largest customer (3 awards, $111.7 million potential value), including a recent $100 million multiple-award Small Construction Task Order Contract II with a ceiling through July 2031, a $11.7 million heating-ventilation-air-conditioning replacement at Kennedy's logistics facility (awarded September 2023, FY2024–2025 SCI-reported invoicing of $7.3 million total), and a $11.9 million dune restoration contract at Naval Station Mayport (awarded September 2023). The Department of the Navy Naval Facilities Engineering Command (3 awards, $22.6 million) and Naval Air Systems Command ($8.5 million for Runway 10-28 Instrument Landing System installation at Naval Air Station Jacksonville) complete the top five. These four agencies account for 99% of combined potential value.
Oneida E&C holds three named parent vehicles: the Space Coast MAC (10 task orders, $7.5 million combined value), the Kennedy Space Center Small Construction Task Order Contract II ($100 million ceiling, total small business set-aside, runs through July 2031), and a Department of Defense Southwest Region indefinite-delivery painting contract ($1.46 million ceiling, 8(a) sole source, three delivery orders through June 2027). The top twenty customers by award count represent 60% of awards; top customers by dollar value represent 99% of combined potential value, signaling heavy concentration in the Air Force Space Command / Kennedy Space Center axis.
Activity has concentrated in 2023 (12 awards) with lower velocity in subsequent years (6 awards in 2024, 2 in 2025, 3 in 2026). Only two awards face ultimate completion inside the next twenty-four months, carrying combined potential value of $12.1 million, limiting near-term recompete exposure. Oneida E&C operates exclusively as a prime contractor across the portfolio; the SCI dataset captures three service-contract records (all prime, zero sub records) spanning FY2024–FY2025, with FY2024 invoicing of $121 thousand (2.6 FTEs) and FY2025 invoicing of $7.2 million (2.2 FTEs) on the Kennedy Space Center HVAC contract. Government-paid hourly rates on SCI-reportable service contracts derived at $22.65 per hour, and the contractor performed 100% of reported hours in-house with no subcontractor engagement captured in SCI. Oneida E&C's award portfolio spans commercial and institutional building construction (17 awards), painting and wall covering (4 awards), and plumbing, heating, and air-conditioning services (2 awards), with the largest individual awards structured as definitive contracts and delivery orders rather than IDIQs, and no evidence of significant subcontract teaming across the source data.
