Justin E. Costello serves as a Contract Specialist within the Public Buildings Service’s R5 Acquisition Management Division, where he plays a pivotal role in executing federal construction and facility support acquisitions under the General Services Administration. He manages the full lifecycle of procurement actions for interior renovations, building systems upgrades, and mission-critical facility services, ensuring compliance with FAR regulations and agency priorities centered on modernizing the federal built environment. His work directly supports the nation’s infrastructure resilience by facilitating timely, efficient, and compliant contract awards for technical and operational services essential to federal building operations. Costello maintains a consistent working relationship with MCKENZIE CONSTRUCTION & SITE DEVELOPMENT LLC, a primary contractor for facility enhancement projects, and engages with a diverse pool of specialty trade contractors and technical consultants. His procurement patterns reflect a preference for established, performance-based vendor partnerships that deliver high-quality construction and facility support services, often through competitive sealed bidding and negotiated acquisitions under simplified acquisition procedures. He prioritizes clarity in performance requirements and robust contract administration to ensure deliverables align with federal building standards. His contracting portfolio demonstrates a strong commitment to small business participation, with nearly half of his awards structured as Total Small Business Set-Asides under FAR 19.5, reflecting a deliberate strategy to expand economic opportunity. He also routinely utilizes 8(a) competed set-asides and Women-Owned Small Business programs, aligning with GSA’s socioeconomic goals while maintaining rigorous competition and value for the government. Costello’s primary procurement focus lies in NAICS 541690 (Other Scientific and Technical Consulting Services), where he sources facility condition assessments, engineering analyses, and operational planning support. He also regularly procures Architectural Services (541310), Building Inspection Services (541350), and Janitorial Services (561720), demonstrating expertise in managing integrated facility lifecycle services that ensure safety, compliance, and operational efficiency across federal properties.
