Sumiyo Ohi

Sumiyo Ohi serves as a Contract Specialist with the FA5209 374th Contracting Squadron under the Department of the Air Force, responsible for managing the full lifecycle of procurement actions critical to sustaining U.S. military operations in Japan. She specializes in facility infrastructure and utility systems, ensuring that essential services—such as heating, ventilation, air conditioning, and plumbing—are delivered in compliance with federal regulations and operational readiness standards. Her acquisitions directly support mission-critical environments across geographically dispersed installations, prioritizing reliability, safety, and regulatory adherence in all contract execution. Ohi maintains longstanding relationships with a select group of trusted contractors, including KOTRACK INCORPORATED, BRANSCOME OPERATING, LLC, MOTOROLA SOLUTIONS, INC., AMD INTERNATIONAL TECHNOLOGIES LLC, and KOTSUKENSETSU CO., LTD. These partnerships reflect a preference for established vendors with proven technical capability in facility systems and mission support services. Her contracting approach emphasizes performance-based outcomes, rigorous quality control, and consistent contractor accountability, fostering stable, long-term vendor collaboration grounded in compliance and operational alignment. Ohi’s procurement portfolio reflects a strict focus on full and open competition, with 100% of her awards issued under no set-aside classifications. She does not routinely utilize socioeconomic programs such as 8(a), HUBZone, or SDVOSB set-asides, instead prioritizing technical competency and mission-critical delivery capacity over socioeconomic criteria. This reflects a mission-driven approach aligned with the operational imperatives of overseas installations, where rapid, reliable service delivery takes precedence over socioeconomic contracting preferences. Her primary technical domain is NAICS 238220—Plumbing, Heating, and Air-Conditioning Contractors—where she procures complex HVAC systems, mechanical infrastructure upgrades, and integrated facility maintenance services. She possesses deep expertise in evaluating technical specifications for climate-controlled environments, energy efficiency standards, and military-grade durability requirements, ensuring all contracted work meets stringent DoD facility performance benchmarks.
