Cathal Duffy

Cathal Duffy serves as a Contract Specialist within the Public Buildings Service’s R4 (AMD) Acquisition Management Division under the General Services Administration, where he plays a pivotal role in executing complex construction and professional services acquisitions for federal infrastructure projects. His responsibilities include developing, negotiating, and administering contracts for the design, construction, renovation, and maintenance of courthouses, federal office buildings, and mission-critical facilities. Duffy applies deep expertise in FAR-based procurement processes, ensuring compliance with federal building standards and sustainability mandates while supporting the agency’s mission to deliver secure, efficient, and resilient federal infrastructure. Duffy maintains a consistent working relationship with MCKENZIE CONSTRUCTION & SITE DEVELOPMENT LLC, a key contractor specializing in commercial and institutional building construction. His procurement patterns reflect long-term vendor partnerships grounded in performance-based outcomes, with a preference for firms demonstrating proven experience in federal facility delivery. He routinely collaborates with contractors who possess robust safety records, design-build capabilities, and familiarity with GSA’s stringent construction protocols. While the majority of his acquisitions—82.2%—are conducted without set-asides, Duffy actively supports socioeconomic objectives by prioritizing Service-Disabled Veteran-Owned Small Business (SDVOSB) set-asides at 13.3% and Total Small Business Set-Asides at 4.4%. His contracting approach balances operational efficiency with statutory obligations to promote small business participation, particularly among firms certified under FAR Part 19. His technical focus centers on NAICS 236220 (Commercial and Institutional Building Construction), which accounts for half of his portfolio, alongside significant procurement activity in architectural services (541310) and engineering services (541330). He regularly manages contracts for integrated design-build teams, mechanical systems installation, and facility modernization projects, demonstrating specialized expertise in the lifecycle management of federal real property.
