Katelyn A. McCullough serves as a Contract Specialist within the Public Buildings Service’s R3 Acquisition Management Division South, where she plays a pivotal role in executing strategic procurement actions to support federal facility modernization across the Mid-Atlantic region. She manages the full lifecycle of acquisitions for construction, engineering, and facility services, ensuring compliance with federal regulations while advancing the agency’s mission to deliver safe, efficient, and sustainable work environments for federal agencies. Her portfolio primarily encompasses design-build, renovation, and infrastructure projects requiring coordination between architects, engineers, and general contractors to meet stringent federal building standards. McCullough collaborates with a diverse pool of contractors specializing in commercial and institutional construction, roofing, and professional engineering services. She fosters collaborative, transparent relationships with both large prime contractors and qualified small business subcontractors, emphasizing performance-based outcomes and contract administration excellence. Her approach prioritizes clear communication, risk mitigation, and adherence to FAR guidelines to ensure timely delivery of mission-critical facility upgrades. Her contracting patterns reflect a strong preference for full and open competition, with 100% of her acquisitions conducted without set-asides, indicating a focus on competitive pricing and technical capability over socioeconomic classifications. While she does not prioritize 8(a), HUBZone, or SDVOSB set-asides, she actively encourages small business participation as subcontractors within larger contracts to promote industry-wide capability development. McCullough’s primary procurement focus lies in NAICS 236220 (Commercial and Institutional Building Construction), followed by 541330 (Engineering Services) and 238160 (Roofing Contractors). She routinely manages complex procurements involving building envelope systems, structural upgrades, HVAC integration, and facility maintenance services, demonstrating deep expertise in federal construction standards, performance specifications, and design-build delivery methods. Her technical acumen ensures that all acquisitions align with GSA’s sustainability and resilience goals for federal infrastructure.
