Sonya B. Plumley

Sonya B. Plumley serves as a Contract Administrator responsible for managing the full lifecycle of procurement actions, from solicitation through contract award and administration. She ensures compliance with federal acquisition regulations and supports the agency’s mission by facilitating timely, transparent, and cost-effective acquisitions across a diverse range of support services. Her work centers on non-defense, mission-critical contracts that enable operational efficiency, with a focus on service-based procurements requiring rigorous performance monitoring and vendor accountability. Plumley collaborates with a broad spectrum of vendors, including small businesses and specialized service providers, to fulfill agency needs in facility support, health-related services, and recreational programming. While no single contractor dominates her portfolio, she consistently engages with firms capable of delivering high-quality, scalable services under performance-based contract structures. Her approach emphasizes clear statement of work development, robust evaluation criteria, and post-award oversight to ensure contractor performance aligns with established deliverables and quality standards. Her procurement patterns reflect a strong preference for open competition, with 100% of her awards issued under non-set-aside authorities. This indicates a deliberate focus on maximizing competition and value through unrestricted solicitations rather than socioeconomic set-asides such as 8(a), HUBZone, or SDVOSB programs. While she does not prioritize designated small business categories, her contracts still frequently involve small businesses due to the nature of the services procured. Plumley’s primary procurement focus lies in NAICS 561720 (Janitorial Services), followed by 611620 (Sports and Recreation Instruction) and 811412 (Appliance Repair and Maintenance). She also regularly acquires services under 621111 (Offices of Physicians) and 561990 (All Other Support Services), demonstrating expertise in procuring facility maintenance, health support, and general administrative services. Her technical domain knowledge centers on service delivery models requiring performance metrics, quality assurance plans, and contract management oversight.
