William G Kamstra

William Kamstra serves as a Contract Specialist within the PBS R10 Services Acquisitions Branch of the General Services Administration’s Public Buildings Service, where he plays a pivotal role in executing mission-critical facilities support contracts. He manages the full lifecycle of procurement actions for integrated operational and maintenance services essential to sustaining federal buildings, ensuring compliance with accessibility standards and infrastructure resilience requirements. His portfolio primarily encompasses facilities support and janitorial services under FAR Part 13 and Part 15 procedures, with a focus on performance-based contracting and service-level agreements that align with GSA’s mission to deliver safe, efficient, and sustainable federal work environments. Kamstra collaborates with a diverse range of vendors, including large national service providers and small business contractors specializing in facility operations, custodial services, and building systems support. While no single contractor dominates his portfolio, he consistently engages with firms capable of delivering nationwide or regionally scalable services under indefinite-delivery/indefinite-quantity (IDIQ) and task order contracts. His working relationships are characterized by a strong emphasis on vendor performance, compliance with labor standards, and adherence to federal facility management benchmarks. He maintains a balanced approach to socioeconomic set-asides, with half of his acquisitions designated as Total Small Business Set-Asides under FAR 19.5, reflecting a deliberate strategy to maximize small business participation. His contracting patterns show no preference for 8(a), HUBZone, or SDVOSB-specific set-asides, indicating a broad-based commitment to all qualified small businesses rather than targeted socioeconomic categories. Kamstra’s primary procurement focus lies in NAICS 561210 (Facilities Support Services) and NAICS 561720 (Janitorial Services), encompassing custodial, waste management, groundskeeping, and building maintenance support. His technical expertise centers on performance-based service delivery models, facility condition assessments, and compliance with federal building codes and sustainability directives, ensuring that contracted services directly support the operational integrity of federal infrastructure.
