Patrick S. Duff

Patrick S. Duff serves as a Contracting Specialist within the Department of the Air Force’s FA4484 organization, responsible for managing complex acquisitions that sustain mission-critical infrastructure at military installations. His portfolio focuses on facility maintenance, construction, and technical services essential to air base operational readiness, including electrical systems, HVAC, environmental compliance, and industrial equipment repair. Duff executes procurements under FAR Part 12 and Part 36, ensuring alignment with DoD sustainability goals and readiness standards while maintaining strict adherence to federal acquisition regulations and safety protocols. He maintains consistent working relationships with a core group of experienced contractors, including PAETZOLD CONSTRUCTION CO INC, RANCO CONSTRUCTION INC, SEQUOIA CONSTRUCTION INCORPORATED, THE PASSANANTE GROUP, LLC, and XENTURIS LLC. These partnerships reflect a preference for established firms with proven capabilities in military facility upgrades, utility system modernization, and specialized maintenance services. Duff’s contracting approach emphasizes performance-based outcomes, rigorous technical evaluations, and long-term vendor reliability over short-term cost savings. Duff demonstrates a strong commitment to small business participation, with approximately half of his acquisitions structured as Total Small Business Set-Asides under FAR 19.5. He also regularly employs Service-Disabled Veteran-Owned Small Business and Women-Owned Small Business set-asides, reflecting a balanced socioeconomic strategy that promotes equitable access to defense contracting opportunities. His pattern of set-aside usage underscores a deliberate effort to cultivate a diverse, resilient small business base capable of supporting long-term infrastructure needs. His primary procurement focus lies in NAICS 238210 (electrical installation) and 811310 (industrial machinery repair), with significant activity in solid waste collection (562111) and other computer-related services (541519). This reflects expertise in managing technical services that support both physical infrastructure and operational systems, requiring deep understanding of military facility standards, environmental regulations, and mission-critical service continuity.
