Jonathan A Rubin

Jonathan A. Rubin serves as a Contract Specialist within the Public Buildings Service’s R5 Acquisition Management Division, where he plays a pivotal role in executing federal facility acquisitions under GSA’s mission to modernize and sustain the nation’s public infrastructure. He manages the full lifecycle of contracts for construction, renovation, and facility support services, with a focus on interior upgrades, building systems modernization, and mission-critical operations. His work ensures compliance with federal acquisition regulations while aligning procurement outcomes with the agency’s strategic priorities for energy efficiency, safety, and operational resilience across federal buildings nationwide. Rubin maintains consistent working relationships with key contractors, notably MCKENZIE CONSTRUCTION & SITE DEVELOPMENT LLC, with whom he collaborates on complex facility enhancement projects. His procurement patterns reflect a preference for established, capable vendors experienced in federal compliance and performance-based service delivery. He fosters long-term partnerships with contractors who demonstrate technical proficiency in building systems integration and facility maintenance, ensuring reliable execution of high-stakes infrastructure projects under strict federal oversight. His contracting approach prioritizes small business participation, with approximately 20% of his portfolio allocated to socioeconomic set-asides—primarily Total Small Business Set-Asides under FAR 19.5 and Service-Disabled Veteran-Owned Small Business (SDVOSB) set-asides. While the majority of his acquisitions remain open to all competitors, he actively promotes equitable access for qualified small and veteran-owned firms, reflecting a deliberate commitment to socioeconomic goals without compromising performance standards. Rubin’s technical expertise centers on NAICS 561720 (Janitorial Services), 221310 (Water Supply and Irrigation Systems), and 238220 (Plumbing, Heating, and Air-Conditioning Contractors), reflecting a strong focus on building operations and maintenance. He routinely procures services related to HVAC system upgrades, water infrastructure repairs, and integrated facility support, demonstrating deep familiarity with performance specifications, maintenance contracts, and life-cycle cost analysis in federal facility management.
