Marrero, Couvillon & Associates, L.L.C.

Marrero, Couvillon & Associates, L.L.C., a Hispanic American-owned and SBA 8(a)-certified small disadvantaged business based in Baton Rouge, Louisiana, operates as a prime contractor delivering architectural, engineering, and construction services to federal agencies across civilian and defense portfolios. The firm competes predominantly under Total Small Business and 8(a) set-aside designations, with 100% of recent awards held as prime contracts. Marrero Couvillon is structured as a partnership or limited liability partnership and maintains three subsidiaries: Mca-Dot JV LLC (Hispanic American-owned DOT-certified DBE joint venture), Arc Mechanical Contractors Inc., and Dbc-Mca JV, LLC (service-disabled veteran-owned joint venture).

Marrero Couvillon's capability portfolio centers on facility construction, renovation, repair, and system replacement work. Concrete recent examples include a $2.74 million greenhouse replacement and heating system renovation at the Jamie Whitten Delta States Research Center in Stoneville, Mississippi (Department of Agriculture, September 2026, under Total Small Business set-aside); a $4.18 million chiller replacement at Federal Detention Center Miami for the Bureau of Prisons (awarded March 2026); a $3.5 million comprehensive campground restoration at Kincaid Campground in Louisiana under the Great American Outdoors Act MATOC (May 2023); and a $6.2 million restoration and conservation contract for the Illinois State Monument at Vicksburg National Military Park (June 2025). Work encompasses mechanical and HVAC system replacement, roof and structural repairs, greenhouse and laboratory modernization, electrical infrastructure upgrades, fire suppression and detection system installation, boardwalk replacement, and emergency disaster recovery. NAICS concentration runs heavily to commercial and institutional building construction (55 awards), plumbing and HVAC contractors (16 awards), and architectural and engineering services (27 awards combined).

Customer concentration sits with civilian agencies in research, facilities, and natural resources. The Department of Agriculture Agricultural Research Service Field Research Implementation and Information Delivery leads by award count at 46 awards ($16.5 million combined potential value), followed by the Bureau of Prisons South Central Regional Office (13 awards, $5 million). The Department of Interior Fish and Wildlife Service and subordinate regions anchor the highest-dollar position through the $250 million Great American Outdoors Act MATOC held by Marrero Couvillon since January 2022, which accounts for $300 million in combined potential value across two awards (the MATOC itself and a related administrative A&E services vehicle). The top five customer groupings account for 52% of recent awards by count but 71% of combined potential value, reflecting USDA's volume-driven posture and DOI's large-ceiling vehicles.

Marrero Couvillon holds multiple indefinite delivery vehicles anchoring its federal footprint. The Great American Outdoors Act MATOC ($250 million, Department of Interior Fish and Wildlife Service, January 2022 through June 2027) has generated 15 task orders worth $17.7 million in combined potential value, supporting alteration and repair construction across national parks, wildlife refuges, and Forest Service properties nationwide. The Department of Army Northeast Region Total Small Business set-aside IDIQ ($84 million, April 2024 through April 2029) has issued four task orders to date, including construction service delivery orders at Fort Leonard Wood, Missouri. The Air Education and Training Command 2025 ALTUS Multiple Award Construction Contract ($95 million, August 2025 through August 2030) represents a Competitive 8(a) multiple-award vehicle with one $500 task order placed to date. A Basic Ordering Agreement with Air Force Special Operations Command (May 2024 through May 2029, $0 floor, $5.3 million ceiling) at Cannon Air Force Base has drawn three delivery orders totaling $7.3 million for airfield runway lighting replacement, approach lighting replacement, and airfield regulator repairs. A Department of Interior A&E Services MATOC ($50 million, September 2022 through September 2027) supports architectural and engineering services across Interior and Forest Service properties nationwide, with at least one $40,481 task order issued by the U.S. Geological Survey in 2023.

Activity has grown modestly from 14 awards in 2022 to a peak of 20 in 2025, with 11 awards recorded through late September 2026. Twelve awards face ultimate completion inside the next twenty-four months, carrying $17.8 million in combined potential value and representing material recompete exposure. The vendor operates exclusively as a prime contractor with no documented sub-award activity, building its own delivery teams rather than leveraging subcontractors at scale. Across SCI-reportable prime service contracts (26 records spanning FY2022–FY2025), Marrero Couvillon invoiced $13.8 million with an average sub-hours share of 11% — indicating light reliance on subcontractor labor across the prime portfolio. The workforce tracked by SCI ranged from 3.9 FTEs in FY2022 to 1.1 FTEs in FY2025 (partial year), with government-paid hourly rates clustering at a median around $308.17/hour and ranging from roughly $91.51/hour (10th percentile) to $1,182.71/hour (90th percentile), reflecting a mix of administrative, technical, and senior engineering labor. Ten named subcontractors appear across the SCI prime contracts when sub work is engaged.

Combined potential value across all 150 prime awards totals $586.7 million, with $59.4 million obligated to date (10% realization). The vendor serves 39 distinct federal agencies, demonstrating broad market reach within the small business federal contractor ecosystem. Disaster recovery work (Hurricane Ida repairs at Naval Base New Orleans and USDA Sugarcane Research facility) and infrastructure modernization at federal research, correctional, and military facilities characterize the prime footprint. Marrero Couvillon's 8(a) certification, alongside DOT DBE and self-certified small disadvantaged business designations held by the parent and subsidiaries, positions the firm as a recurring awardee under small-business-reserved federal construction and engineering solicitations across Interior, Agriculture, Defense, and Justice procurement portfolios.
