Gulf South Research Corp

Gulf South Research Corp, a women-owned small business headquartered in Baton Rouge, Louisiana, operates as a prime contractor providing environmental consulting, natural resource management, and ecological services to federal agencies. The firm holds SBA certifications as a Women-Owned Small Business (WOSB) and Economically Disadvantaged Women-Owned Small Business (EDWOSB), and competes predominantly in open federal procurements and through set-aside vehicles; recent awards show a near-even split between set-aside and full-and-open competition, with significant work flowing through WOSB and total small business set-asides on major IDIQs.

Gulf South's customer concentration is heavily skewed toward defense and civil works agencies. The Department of the Navy Naval Facilities Engineering Command dominates by potential value at $274.9 million across 79 awards, followed by the Department of the Air Force Materiel Command Installation and Mission Support Center at $139.7 million across 11 awards and the Army Corps of Engineers Fort Worth District at $128.3 million across 321 awards (the largest award count). Together these three customers account for 71% of combined potential value and 46% of award count. The Army Corps of Engineers (all districts combined) represents the single largest customer family by volume, with over 100 awards and $293.3 million in combined potential value across multiple organizational units. Gulf South serves 73 distinct federal agencies, but concentration remains sharp—the top five customers represent 58% of awards.

Gulf South holds three major parent vehicles anchoring its federal work. The Naval Facilities Engineering Command's $98.5 million Habitat and Invasive Species Services IDIQ (Total Small Business set-aside, March 2032 completion) generates substantial task order volume, with work concentrated on habitat restoration, invasive species control, erosion management, and endangered species surveys across six Southwestern states (Arizona, California, Colorado, Nevada, New Mexico, Utah). The Army Corps of Engineers Sacramento District's $49 million Cultural and Environmental Resources Services MATOC (Total Small Business set-aside, September 2027 completion) funds aquatic resource monitoring, fish tagging, entrainment monitoring, and water quality assessment. The Army Corps of Engineers Seattle District awarded a new $45 million WOSB IDIQ (March 2029 completion) in April 2026 for environmental consulting services. Beyond IDIQs, Gulf South holds positions on the GSA Multiple Award Schedule (MAS) and the Professional Services Schedule, accounting for numerous task orders across Customs and Border Protection, the Department of Interior, and other civilian agencies for environmental assessment and construction monitoring work.

Representative prime contracts illustrate the breadth of Gulf South's scope. A $7.8 million Customs and Border Protection delivery order (July 2026, MAS vehicle) covers natural and cultural resource monitoring for border wall construction in El Paso, Texas. A $9.6 million CBP order (March 2026, under the Army Corps of Engineers Sacramento MATOC) funds cultural and natural resources monitoring for border wall segments in the Laredo Sector. A $1.35 million Army Corps of Engineers delivery order (August 2024) provides juvenile green sturgeon monitoring in the lower Sacramento River to comply with a 2021 NOAA Fisheries biological opinion. Multiple $300K–$400K Navy task orders focus on pre- and post-fire habitat management, vegetation plan updates, and vernal pool restoration at Camp Pendleton and other installations. A $786 thousand Fish and Wildlife Service purchase order (August 2023) covers invasive species management across 900 acres of South Texas national wildlife refuges over four years.

Activity has grown modestly: 13 awards in 2022, 20 in 2023, 15 in 2024, and 21 in 2025. In 2026 (partial year), Gulf South has already recorded seven awards. The combined portfolio spans 1,094 prime awards with $1.05 billion in potential value and $222.8 million obligated (21% realized). Thirty-one awards totaling $53.9 million in potential value reach completion within the next twenty-four months, creating recompete exposure concentrated in Navy and Army Corps work.

Gulf South's core capability portfolio centers on environmental consulting and natural resource management. Work encompasses environmental assessments (378 awards under NAICS 541620 / PSC H—Environmental Assessments), habitat restoration and invasive species control (367 awards), engineering and landscaping design services (103 awards), and remediation services (77 awards). The firm executes endangered species surveys (Quino checkerspot butterfly, California towhee, desert tortoise, Island Fox, salt marsh bird's beak, Stephen's kangaroo rat), erosion control and stabilization, vernal pool and wetland restoration, vegetation and water quality monitoring, fish tagging and entrainment monitoring, invasive plant treatment and biomass removal, and cultural resource surveys including archaeological Class III work. Work is performed across the Southwest (California, Arizona, Nevada, Utah, New Mexico, Colorado), along the U.S.-Mexico border, and at scattered Department of Defense installations nationwide.

Service Contract Inventory data covering FY2022–FY2024 shows minimal reported invoiced revenue and roughly 1.8 FTEs on SCI-reportable contracts in FY2024, indicating that SCI captures a small fraction of Gulf South's federal environmental services activity; the majority of the company's work is project-based, task-order-driven delivery under IDIQs and MAS vehicles with firm fixed pricing, not time-and-materials labor contracts above the $150,000 SCI threshold. Gulf South operates virtually entirely as a prime contractor (100% of awards in the source data are prime), and does not rely on material subcontractor engagement on SCI-reportable contracts.

Gulf South competes across both set-aside and full-and-open categories. Recent awards show roughly 40–50% flowing through WOSB, EDWOSB, or Total Small Business set-asides, with the balance awarded on competitive open basis, reflecting the firm's dual positioning as a certified small business capable of winning set-aside vehicles while also securing larger task orders in unrestricted competition.
