Leah M. DeCosta

Leah M. DeCosta serves as a Contract Specialist within the PBS R3 Acq Management Division of the General Services Administration’s Public Buildings Service, where she plays a pivotal role in executing strategic procurements to support federal facility operations across Region 3. She manages the full lifecycle of contracts for real estate leasing, building maintenance, and facility services, ensuring compliance with federal acquisition regulations while advancing the agency’s mission to deliver safe, efficient, and modernized workspaces. Her acquisitions primarily involve service-based contracts requiring technical oversight, performance-based management, and stringent quality control standards to sustain federal infrastructure. Leah collaborates with a diverse pool of vendors specializing in commercial and industrial equipment repair, as well as architectural and engineering design services. While no single contractor dominates her portfolio, she consistently engages with firms possessing demonstrated capability in facility operations, preventive maintenance systems, and building envelope remediation. Her working relationships emphasize vendor reliability, past performance evaluation, and adherence to federal sustainability and safety standards, fostering long-term partnerships grounded in accountability and regulatory compliance. Leah’s contracting activity is entirely non-set-aside, with 100% of her procurements awarded through full and open competition. This reflects a deliberate strategic alignment with agency priorities that prioritize technical merit, cost-effectiveness, and broad market participation over socioeconomic set-asides. While she does not routinely utilize 8(a), HUBZone, or SDVOSB programs, her process remains transparent and inclusive, ensuring all qualified vendors have equitable access to opportunities based on capability and compliance. Her primary procurement focus lies in NAICS 811310 (commercial and industrial machinery and equipment repair and maintenance) and NAICS 541310 (architectural services), indicating deep expertise in facility systems upkeep and design-related professional services. She routinely procures HVAC maintenance, structural assessments, energy efficiency retrofits, and building code compliance services, demonstrating specialized knowledge in federal building operations and lifecycle asset management.
