About the company
Castor, LLC, a service-disabled veteran-owned small business (SDVOSB) based in Baton Rouge, Louisiana, delivers facility maintenance, repair, and construction services to federal agencies as a prime contractor, holding SBA 8(a) and SBA small disadvantaged business certifications. The company operates exclusively as a prime (100% of recent awards) and competes across both set-aside and full-and-open vehicles, with 8(a) Sole Source and Total Small Business set-asides anchoring higher-dollar work.
Castor's capability portfolio centers on facility infrastructure work: building and structural repairs, HVAC systems maintenance, fuel infrastructure and tank removal, paving and erosion repair, security systems upgrades, and storm damage restoration. Representative work includes a $1.64 million 8(a) Sole Source definitive contract awarded by Navy Installations Command in January 2026 for splash pad park repairs in New Orleans, Louisiana; a $1.28 million firm fixed-price definitive contract awarded by an unnamed Southeast Region agency on September 30, 2026, for an equipment storage building at the Golden Meadow PMC in Galliano, Louisiana; and a $308,483 full-and-open definitive contract from Customs and Border Protection on September 29, 2026, for a PACS upgrade at a St. Augustine, Florida facility. Smaller purchase orders include $23,934 from the National Oceanic and Atmospheric Administration for wooden platform inspection and repair at the Berwick NWLON Station in Gibson, Louisiana, and $9,325 from the Department of Agriculture's Agricultural Research Service for HVAC coil installation at the Sugarcane Research Unit in Schriever, Louisiana.
Customer concentration is heavily weighted to the Army Corps of Engineers' Engineer Research and Development Center, which accounts for 9 of 16 awards (56%) and $11.9 million of the $15.3 million combined potential value. The top five customer agencies cover 100% of potential value, with Navy Installations Command, the Department of Agriculture, Customs and Border Protection, and the Air National Guard rounding out the active set. The Department of the Navy carries one high-dollar award; the remaining customers place smaller individual orders.
Castor holds a single-award $9 million indefinite delivery contract (IDC W912HZ23D0007) with the Army Corps of Engineers' Engineer Research and Development Center, set aside for SDVOSBs and running through May 2026. Eight delivery orders have been issued against this vehicle, totaling $2.9 million in combined potential value for work including culvert repairs, chiller replacement, fuel infrastructure maintenance, lift station repair, perimeter fence repairs, paving repairs, and erosion control at ERDC facilities in Baton Rouge and Vicksburg, Mississippi. No other parent vehicles appear in the award portfolio; all other work flows through definitive contracts and purchase orders.
Award activity has grown from one contract in 2022 to six in 2024, with five awards in 2026 year-to-date. Four awards (combined potential value $3.2 million) reach ultimate completion within the next twenty-four months, presenting recompete exposure. The vendor's geographic footprint spans Louisiana, Mississippi, and Florida, with performance concentrated at ERDC facilities and smaller federal installations across the Southeast. NAICS concentration skews heavily to foundation, structure, and building exterior contracting (9 awards), with secondary NAICS classes in commercial building construction and building finishing trades.
