Buck Silveira

Buck Silveira serves as a Maintenance Mechanic within the USDA Agricultural Research Service’s Procurement and Workforce Administration office (Agency Code: 12905B), where his technical expertise directly supports the agency’s mission to sustain and modernize critical research infrastructure. While not a contracting officer, Silveira plays a vital operational role in identifying, evaluating, and specifying maintenance and facility-related procurement needs—ranging from laboratory equipment servicing to structural repairs and specialized tooling. His hands-on experience informs acquisition requirements for precision maintenance services and facility upgrades essential to sustaining high-functioning agricultural research environments, ensuring that procurement actions align with technical specifications and operational uptime demands. Silveira collaborates closely with specialty trade contractors and technical service vendors who provide skilled labor for facility upkeep, instrumentation calibration, and mechanical system repairs. He works primarily with small to mid-sized firms capable of delivering rapid-response maintenance, retrofitting of aging infrastructure, and compliance with federal safety and environmental standards. His working relationships are built on reliability, technical proficiency, and the ability to meet stringent research facility operational requirements, often under tight timelines. His procurement patterns reflect a strong inclination toward small business participation, with nearly 43% of associated acquisitions set aside for total small businesses and 14.3% reserved for service-disabled veteran-owned small businesses. This demonstrates a deliberate commitment to leveraging socioeconomic programs to access agile, locally rooted vendors capable of supporting mission-critical maintenance needs without compromising quality or responsiveness. Silveira’s primary procurement focus centers on NAICS 238990 (All Other Specialty Trade Contractors), reflecting demand for specialized facility maintenance and repair services. He also routinely sources institutional furniture, prefabricated metal components, poured concrete structures, and analytical laboratory instrumentation—domains requiring precise technical specifications and adherence to federal research facility standards. His expertise lies at the intersection of mechanical systems, facility integrity, and research continuity, ensuring that procurement decisions directly enable the scientific mission of the Agricultural Research Service.
