Larry Sizer

Larry D. Sizer serves as a Contract Specialist within the Department of the Air Force’s FA2517 21 Cons Bldg 350 office, where he plays a pivotal role in executing mission-critical procurement actions to modernize defense infrastructure and enhance operational readiness. He manages the full lifecycle of acquisitions for facility systems, electronic communications, and security services, ensuring compliance with federal acquisition regulations and alignment with Air Force strategic priorities. His work directly supports the sustainment and upgrade of critical installations, with a focus on resilient, secure, and technologically advanced environments. Sizer maintains consistent working relationships with a select group of prime contractors, including ASTERI CONSULTING SERVICES LLC, AMD INTERNATIONAL TECHNOLOGIES LLC, MCKENZIE CONSTRUCTION & SITE DEVELOPMENT LLC, ARHAB LLC, and PRIMEPRO BUSINESS SOLUTIONS LLC. These partnerships reflect a preference for firms with proven expertise in facility modernization, integrated security systems, and technical services tailored to defense infrastructure needs. His contracting approach emphasizes performance-based outcomes and long-term vendor collaboration to ensure mission continuity and system interoperability. A strong advocate for small business participation, Sizer consistently prioritizes Total Small Business Set-Asides under FAR 19.5, with over 73% of his acquisitions reserved for small businesses. This pattern underscores a deliberate commitment to socioeconomic contracting goals, fostering opportunities for small firms to contribute to national defense capabilities without reliance on large prime contractors or no-set-aside mechanisms. His primary procurement focus centers on NAICS 561621 (Security Systems Services), reflecting deep expertise in electronic surveillance, access control, and integrated threat detection systems. He also routinely procures computing infrastructure services (NAICS 518210) and specialized equipment including irradiation apparatus (NAICS 334517), demonstrating technical fluency across both physical and digital defense systems essential to modern Air Force installations.
