Marcella F. McWhorter

Marcella F. McWhorter serves as a Purchasing Agent within the PBS R6 Services Acquisition Branch of the General Services Administration’s Public Buildings Service, where she plays a pivotal role in procuring mission-critical facilities support services to maintain federal buildings and grounds. Her responsibilities encompass the full lifecycle of acquisitions for custodial, landscaping, building operations, and related maintenance services, ensuring compliance with federal procurement regulations and operational readiness standards. She works closely with program managers and facility coordinators to translate facility needs into solicitations that deliver reliable, cost-effective, and sustainable services across the federal real estate portfolio. While specific contractor relationships are not currently available in the dataset, McWhorter engages with a broad spectrum of vendors capable of delivering integrated facilities management solutions, including both large service providers and local service contractors with proven track records in federal facility operations. Her procurement approach emphasizes performance-based contracting, clear statement of work development, and vendor accountability through outcome-driven deliverables and service level agreements. McWhorter’s contracting activity reflects a strong preference for open competition, with 100% of her acquisitions conducted without set-aside designations. This indicates a focus on maximizing value and efficiency through unrestricted competition, rather than socioeconomic set-asides such as 8(a), HUBZone, or SDVOSB programs. Her approach prioritizes capability, capacity, and past performance over socioeconomic classification, aligning with the branch’s operational imperatives. Her primary procurement focus lies in NAICS categories related to building cleaning and maintenance services, groundskeeping, and facility operations support. She routinely manages contracts for janitorial services, waste removal, pest control, snow removal, and preventive building maintenance, demonstrating deep expertise in facilities management procurement and the unique demands of federal infrastructure stewardship.
