About OST Services, LLC

OST Services, LLC, a Service-Disabled Veteran-Owned Small Business based in Tampa, Florida, provides mechanical infrastructure installation, maintenance, and repair services to the Department of Veterans Affairs as a prime contractor, operating exclusively within a single federal customer with no subcontract footprint. The company holds active SBA certifications as both a Service-Disabled Veteran-Owned Small Business (SDVOSB) and Veteran-Owned Small Business (VOSB), both expiring September 30, 2028, and competes predominantly under SDVOSB set-asides — approximately half of the recent award base (15 of 32 awards) carries SDVOSB sole-source or competitive set-aside designation, with the remainder awarded full-and-open or undesignated.

OST Services operates in narrow, high-specialization mechanical verticals: HVAC and refrigeration equipment repair and replacement (17 awards across plumbing, heating, and air-conditioning contracting NAICS 238220), pump and compressor installation and maintenance (3 awards), and critical hospital facility operations support (3 awards). The company's recent work spans two mega-capital projects — a $1.39 million SDVOSB delivery order in September 2025 for design, fabrication, and installation of a 1,000-ton modular magnetic bearing chiller system to address capacity constraints at the James A. Haley VA Healthcare System, and a $1.27 million SDVOSB definitive contract awarded July 2023 for design-build replacement of supply and exhaust fan arrays in air-handling units — alongside dozens of smaller emergency repairs, equipment replacements, and rental services. Tactical examples include a $345 thousand firm fixed-price purchase order for urgent domestic water pump skid building awarded April 2026 (ultimate completion June 23, 2026, SDVOSB sole source), a $242,600 SDVOSB order for critical air monitoring services including semi-annual negative-pressure room inspections and HEPA filter replacement at James A. Haley Hospital (awarded December 2024, running through December 2029 with four optional 1-year renewals), and $560 thousand in emergency replacement of two York air cooler chillers in Building 30 (awarded September 2022).

Customer concentration is absolute: all 32 awards and the full $8.5 million combined potential value derive from a single funding agency — the Department of Veterans Affairs, Veterans Integrated Service Network 8 (VISN 8), which operates VA medical centers in Florida. This concentration eliminates vehicle, customer-diversification, and recompete-cliff risk signals; OST Services does not sit on government-wide vehicles, GWACs, or BPAs. Activity has remained modest and stable — between two and five awards per calendar year over the past five years — with only two awards (combined potential value $340 thousand) reaching completion within the next twenty-four months. The vendor operates as a 100% prime contractor with no recorded subcontract work and no parent IDIQs or IDVs in the source data, meaning competitive positioning occurs solely on direct VA purchase orders and definitive contracts. Roughly 91 percent of combined potential value has been obligated across the recent award portfolio, indicating strong execution velocity on announced work.
