Brock A. Wilson serves as a key procurement professional within the FA4625 509 Cons Cc, a critical unit of the Department of the Air Force responsible for sustaining operational readiness through facility infrastructure and mission-enabling services. He manages a diverse portfolio of construction, maintenance, and logistics contracts essential to maintaining secure, functional Air Force installations. His acquisitions focus on facility construction, environmental remediation, site preparation, and specialized technical support services, ensuring bases remain mission-ready and compliant with federal infrastructure standards. Wilson’s work directly supports the Air Force’s strategic imperative to modernize and resiliently sustain its global footprint. Wilson maintains consistent working relationships with a core group of contractors, including MCKENZIE CONSTRUCTION & SITE DEVELOPMENT LLC for site development, K & M TRANSPORTATION SERVICES LLC for logistics and transportation support, N2GRATE GOVERNMENT TECHNOLOGY SOLUTIONS, LLC for technical systems integration, and AZTEK COMPUTERS, LLC for specialized equipment maintenance. These partnerships reflect a preference for established vendors with proven capabilities in military-grade infrastructure and service delivery, often engaging them across multiple contract vehicles to ensure continuity and operational reliability. Wilson demonstrates a strong commitment to small business participation, with over half of his acquisitions set aside for small businesses under FAR 19.5, reflecting a deliberate strategy to broaden vendor diversity. HUBZone and Service-Disabled Veteran-Owned Small Business set-asides are also consistently utilized, aligning with Department of Defense socioeconomic goals. While the majority of awards are small business set-asides, he also employs open competitions where appropriate, balancing compliance with mission efficiency. His procurement focus centers on NAICS codes 236220 (commercial and institutional building construction), 237310 (highway and bridge construction), 561730 (landscaping services), and 811310 (commercial machinery repair), indicating deep expertise in civil works, environmental maintenance, and facility sustainment. He routinely procures turnkey construction, site grading, utility upgrades, and industrial equipment servicing critical to base resilience and mission continuity.
