Quadrant Construction Inc.

Quadrant Construction Inc., a HUBZone-certified small business headquartered in Jacksonville, North Carolina, operates as a prime contractor delivering civil construction, facility maintenance, repair, and infrastructure services to Department of Defense installations, predominantly under Total Small Business and HUBZone set-asides. The firm is structured as a for-profit Subchapter S corporation with a 100-percent prime-contractor footprint (176 total awards across the source data, zero sub-awards) and competes nearly exclusively under set-aside categories—Total Small Business and HUBZone designations recur across 98 percent of recent awards.

Quadrant's customer concentration is extreme and geographically focused. The U.S. Marine Corps accounts for 148 awards and $1.11 billion in combined potential value (approximately 58 percent of the vendor's total portfolio), and the Department of the Navy Naval Facilities Engineering Command (NAVFAC) holds an additional 18 awards worth $800.3 million (42 percent). The remaining five customer agencies—Naval Air Systems Command, Defense Logistics Agency Aviation, Naval Sea Systems Command, and Bureau of Medicine and Surgery—represent less than one percent of combined potential value. All work is performed at Marine Corps installations in North Carolina and Virginia, particularly Camp Lejeune and Marine Corps Air Station Cherry Point.

Quadrant holds three significant indefinite delivery vehicles totaling $630 million in ceiling value. The largest is a $495 million Multiple Award Construction Contract (MACC) awarded by NAVFAC on September 29, 2025, under a Total Small Business set-aside, supporting design-build and design-bid-build general construction, renovation, alteration, and repair services at Camp Lejeune and MCAS Cherry Point through September 28, 2030. A single-award $40 million IDC for general maintenance and repair construction services at the same installations runs through December 18, 2029. A third single-award $95 million contract with NAVFAC for civil paving, construction, and infrastructure repair and maintenance services runs through January 25, 2028. Work under these vehicles spans structural repairs, mechanical and plumbing systems, electrical work, civil infrastructure, grounds and road maintenance, pavement work, communications systems, demolition, and flooring installation. Representative delivery orders include a $1.83 million FY 25 multi-area asphalt repair program at Camp Lejeune (August 2025), a $745,258 parking lot expansion at Camp Lejeune (August 2025), a $608,987 grounds improvement project at Camp Lejeune (June 2025), and a $3.97 million fabric shelter installation at MCAS Cherry Point (December 2024).

Activity has grown from seven awards in 2021 to sixteen in 2024, with thirteen in 2025, indicating strong recent momentum. However, the recompete cliff is minimal: only one award ($314 thousand) faces ultimate completion within the next twenty-four months, suggesting that Quadrant's major contract vehicles are stable through the 2026–2028 period. The vendor's primary capability focus aligns with top NAICS categories—Commercial and Institutional Building Construction (92 awards), Plumbing, Heating, and Air-Conditioning Contractors (54 awards), and Highway, Street, and Bridge Construction (30 awards)—and top PSC codes center on repair or alteration of miscellaneous buildings (95 awards).
