Diana Schlumpf

Diana Schlumpf serves as Assistant Property Manager at the Public Buildings Service’s R9 AMD SAT Los Angeles Support Section under the General Services Administration, where she supports the lifecycle management and operational readiness of federal facilities. Her role involves coordinating procurement activities for building maintenance, infrastructure upgrades, and facility modernization services, ensuring compliance with federal property standards and lifecycle efficiency goals. She typically handles acquisitions related to building operations, security systems, and space management, working closely with facility engineers, maintenance teams, and project managers to align contracting decisions with physical plant requirements and long-term asset sustainability objectives. While no specific contractor relationships are currently identified in available records, Schlumpf’s procurement activities suggest collaboration with vendors specializing in nonresidential building leasing, engineering design, and security systems integration. Her working relationships are likely structured around performance-based service contracts and task orders under GSA schedules, emphasizing vendor reliability, regulatory compliance, and timely delivery of facility support services. She engages with a mix of large-capacity service providers and small businesses, prioritizing contract performance and operational continuity over transactional volume. Schlumpf’s contracting patterns reflect a strong preference for open competition, with 93.8% of acquisitions conducted without set-asides. However, she consistently allocates 6.3% of opportunities to Total Small Business Set-Asides under FAR 19.5, demonstrating a measured but intentional commitment to small business participation without sacrificing mission-critical capacity or scale. Her approach balances broad market access with targeted socioeconomic goals, aligning with GSA’s broader equity and efficiency mandates. Her primary procurement focus lies in NAICS 531120 (Lessors of Nonresidential Buildings), reflecting her central role in managing leased federal space. She also procures engineering services (541330), security systems (561621), office furniture (337214), and moving services (484210), indicating broad expertise in facility operations, environmental controls, and tenant support infrastructure. Schlumpf’s technical domain centers on integrated facility management, with deep familiarity in building systems coordination and federal property compliance frameworks.
