About Southern Contracting, LLC
Southern Contracting, LLC, a veteran-owned, SBA-certified HUBZone small business headquartered in Biloxi, Mississippi, operates as a prime contractor delivering heavy construction, civil engineering, and infrastructure services to the Department of Defense, Department of the Army Corps of Engineers, Department of Veterans Affairs, and Department of the Interior. The firm competes across full-and-open and HUBZone set-aside federal procurements, with its recent award portfolio split between Total Small Business set-asides and unrestricted competitions.
Southern Contracting's capability footprint centers on water and sewer infrastructure, runway and airfield repairs, concrete construction, environmental remediation, facility renovation, and floodwall construction. Representative prime work includes a $32.8 million HUBZone set-aside definitive contract from Air Education and Training Command to renovate Bryan Hall at Keesler Air Force Base, Mississippi (awarded October 2023, with Glass Solutions, Inc., a veteran-owned small business, as a named subcontractor for storefront and glass work); a $25.1 million Total Small Business set-aside from the Department of the Army for reinforced concrete floodwall construction in Caruthersville, Missouri (awarded April 2022, completion date December 2027); a $21.6 million National Park Service contract to rehabilitate parkwide utility infrastructure at Catoctin Mountain Park, Maryland (awarded July 2024); and a $4.5 million Army Corps of Engineers Mobile District contract for design and construction of a water treatment plant expansion in Gautier, Mississippi (awarded March 2025).
The vendor holds five significant indefinite delivery contracts totaling $247 million in combined ceiling value. The largest is a $98 million Multiple Award MATOC with the U.S. Army Corps of Engineers New Orleans District for repairs, maintenance, and construction services, awarded February 2025 and running through February 2030 under Total Small Business set-aside. Two additional $49 million MATOCs sit with USACE Mobile District — one for water and sewer civil works (awarded July 2025) and one for design, repair, and construction support for civil works (awarded June 2025), both Total Small Business set-asides. A $45 million HUBZone multiple-award MATOC for environmental remediation services is held with USACE Memphis District (awarded March 2024, completion April 2029). A $6 million multiple-award contract for paving and infrastructure services sits with Air Education and Training Command (awarded September 2023, completion September 2026).
Customer concentration runs heavily toward the Department of the Army Corps of Engineers and its district offices. The top five customers by potential-value ranking account for 75 percent of combined award value: USACE (general) at $172.8 million across seven awards; USACE Mobile District at $110.5 million across seven awards; USACE Galveston District at $90.2 million across seven awards; Air Education and Training Command at $81 million across nine awards; and the Department of the Army at $27.9 million across two awards. By award count, Veterans Affairs Veterans Health Administration Veterans Integrated Service Network 16 ranks first at 13 awards worth $25.3 million (largely small-dollar health facility maintenance), followed by Air Education and Training Command at nine awards.
Activity has accelerated in the past two years. The vendor received one award in 2021, four in 2022, four in 2023, four in 2024, and nine through September 2025. Four awards face ultimate completion within the next twenty-four months with combined potential value of $62.4 million, creating moderate recompete exposure. The vendor operates exclusively as a prime contractor (100 percent of awards); no subcontract activity appears in the source data. SCI reporting captures only one contract — the Catoctin Mountain Park utility rehabilitation work — with $112 thousand invoiced in FY2024 and no subcontractor hours reported, reflecting the vendor's self-performance posture on that engagement. NAICS concentration runs across heavy civil engineering construction (27 awards), highway and bridge construction (22 awards), and water and sewer line construction (13 awards). Primary PSC codes align with repair, alteration, and restoration of real property and airport runway and taxiway work.
