Kiersten D. Sellers

Kiersten D. Sellers serves as a Contract Specialist within the Public Buildings Service’s R4 (AMD) Acquisition Management Division under the General Services Administration, where she plays a pivotal role in managing the full lifecycle of federal construction acquisitions. Responsible for soliciting, evaluating, and awarding contracts for mission-critical infrastructure projects, she ensures compliance with federal procurement regulations while advancing the agency’s mission to deliver secure, efficient, and sustainable federal facilities. Her portfolio primarily encompasses design-build and construction management contracts for courthouses, federal office complexes, and other institutional buildings, requiring deep expertise in FAR Part 36 and integrated project delivery methods. Kiersten maintains a strong, consistent working relationship with McKenzie Construction & Site Development LLC, a trusted prime contractor with demonstrated capability in complex federal construction environments. Her procurement approach emphasizes collaborative vendor partnerships built on performance reliability, regulatory adherence, and proactive communication, fostering long-term engagement with contractors who consistently meet high standards for safety, quality, and schedule compliance. She demonstrates an unwavering commitment to small business participation, directing 100% of her construction acquisitions toward total small business set-asides under FAR 19.5. This reflects a deliberate strategy to maximize economic opportunity for small firms capable of delivering high-quality commercial and institutional construction services, aligning with federal socioeconomic goals and promoting equitable access to federal contracting. Her technical focus is exclusively on NAICS 236220—Commercial and Institutional Building Construction—where she specializes in procuring turnkey construction services including site development, structural framing, MEP systems integration, and facility modernization. Her expertise lies in managing complex, multi-phase projects requiring coordination among architects, engineers, and specialty subcontractors, ensuring outcomes that meet federal building standards and sustainability benchmarks.
