Walter Kalista

Walter Kalista serves as a key procurement lead within the Public Buildings Service’s PBS R11 Construction Services Division Center 2 (47PM02), where he manages mission-critical acquisitions for federal facility modernization across the National Capital Region. His role centers on executing integrated design-build contracts and facilities support services that align with GSA’s mandate to deliver safe, efficient, and sustainable federal infrastructure. He specializes in full lifecycle procurement strategies—from planning and requirements development to contract award and performance oversight—ensuring alignment with federal construction standards and placemaking objectives. His acquisitions typically involve complex, multi-year projects requiring coordination among architects, engineers, and operational stakeholders to support high-visibility federal campuses. Kalista maintains a collaborative procurement environment focused on fostering long-term vendor partnerships with qualified contractors capable of delivering design-build and facilities support solutions under performance-based contract structures. While specific contractor names are not publicly disclosed, his working relationships emphasize firms with proven expertise in federal construction, maintenance, and facility operations, often engaging through indefinite-delivery/indefinite-quantity (IDIQ) vehicles and performance-based service agreements. He prioritizes contractors with demonstrated capacity for integrated project delivery, lean construction methodologies, and sustainable building practices. His procurement pattern reflects a strict 100% Small Business Set-Aside preference under FAR 19.5, demonstrating a robust commitment to socioeconomic equity and small business development. All acquisitions are structured to maximize participation from small businesses, including 8(a), HUBZone, and women-owned small businesses, ensuring broad access to federal construction opportunities. This approach supports GSA’s broader goals of inclusive economic growth and community impact through federal spending. Kalista’s technical focus is exclusively on NAICS 561210 (Facilities Support Services), encompassing building maintenance, custodial services, groundskeeping, energy management, and preventive facility operations. He procures comprehensive, performance-based service packages that integrate maintenance, repair, and operational support for federal buildings, emphasizing reliability, compliance, and lifecycle cost efficiency. His domain expertise lies in sustaining mission-critical infrastructure through proactive, contractually embedded facility management solutions.
