Annelie Jeselski

Annelie Jeselski serves as a Program Analyst within the Public Buildings Service’s R5 Acquisition Management Division, supporting the procurement of mission-critical facility services for federal buildings nationwide. In this role, she plays a key part in executing the division’s mandate to modernize and maintain federal infrastructure through strategic acquisition planning, contract administration, and performance oversight. Her responsibilities center on managing solicitations and contract actions for building systems upgrades, interior renovations, and facility operations, ensuring compliance with federal procurement regulations and alignment with GSA’s infrastructure modernization goals. She works closely with project managers, engineers, and contracting officers to translate technical requirements into enforceable contract deliverables. Annelie maintains a consistent working relationship with MCKENZIE CONSTRUCTION & SITE DEVELOPMENT LLC, a primary contractor engaged in delivering construction and site development services for federal facilities. Her procurement patterns reflect a preference for established, experienced vendors with proven track records in federal construction and facility support, fostering long-term partnerships grounded in performance accountability and regulatory compliance. While she collaborates with a limited number of core contractors, her engagements are characterized by rigorous evaluation of technical capability, past performance, and operational readiness. Annelie’s contracting activity is entirely non-set-aside, with 100% of her awards issued under full and open competition. This reflects a strategic emphasis on maximizing market access and selecting the most qualified providers regardless of socioeconomic status, consistent with the agency’s focus on mission-critical outcomes over socioeconomic preferences. Her primary procurement focus lies in NAICS 561621 (Security Systems Services) and 238220 (Plumbing, Heating, and Air-Conditioning Contractors), underscoring her expertise in integrated building systems. She routinely procures security infrastructure, HVAC upgrades, and related mechanical services essential to the operational integrity and safety of federal properties, demonstrating deep technical familiarity with facility systems modernization.
