TSgt Sean Willian

Sean C. Willian serves as a Contracting Apprentice within the 436th Contracting Squadron, Department of the Air Force, supporting the operational readiness of Air Force installations through the acquisition of critical facility and infrastructure services. In this entry-level role, he assists senior contracting officers in the full lifecycle management of procurements, including solicitation development, source selection support, contract administration, and compliance with FAR and DFARS regulations. His work directly enables the sustainment of mission-critical air base operations, focusing on construction, maintenance, and security systems essential to aircraft support and installation resilience. While specific contractor relationships are not yet established due to his apprenticeship status, Willian collaborates closely with a network of small business vendors, particularly those certified under socioeconomic programs, to ensure equitable access to DoD contracting opportunities. He supports the squadron’s emphasis on fostering vendor partnerships with local and regional firms, cultivating relationships with contractors specializing in commercial construction, industrial maintenance, and security services to meet dynamic installation needs. Willian operates under a 100% Small Business Set-Aside policy, reflecting the squadron’s strong commitment to socioeconomic contracting. He actively supports the use of FAR 19.5 small business set-asides, prioritizing participation from small disadvantaged businesses, HUBZone firms, and service-disabled veteran-owned small businesses. His work reinforces the agency’s mandate to maximize small business engagement across all procurement actions. His primary procurement focus centers on NAICS 236220 for commercial and institutional building construction, with additional emphasis on NAICS 336112 for aircraft component manufacturing support, 811310 for industrial machinery repair, and 561621 for security systems services. He is developing expertise in procuring facility infrastructure, maintenance of aircraft support equipment, and perimeter security systems critical to Air Force base operations.
