Roberta E. Cantara

Roberta E. Cantara serves as a Contract Specialist within the PBS R10 Services Acquisitions Branch of the General Services Administration’s Public Buildings Service, where she plays a pivotal role in executing integrated facilities management contracts to sustain federal building operations. Her responsibilities include developing, soliciting, awarding, and administering service-based acquisitions that ensure the safety, accessibility, and operational efficiency of federal facilities. She specializes in procurement under FAR Part 12 and Part 37, focusing on performance-based service contracts that emphasize outcomes over inputs. Her portfolio consistently supports mission-critical building operations through comprehensive maintenance and support services. Roberta cultivates collaborative relationships with a diverse pool of vendors, including small businesses, service-disabled veteran-owned firms, and HUBZone-certified contractors, fostering long-term partnerships grounded in compliance and performance accountability. She works closely with contractors delivering janitorial, landscaping, food service, and professional technical services, ensuring alignment with federal facility standards and sustainability goals. Her contracting approach prioritizes transparency, competitive bidding, and vendor engagement to build a resilient and responsive supplier base. Her procurement strategy reflects a strong commitment to socioeconomic goals, with nearly 57% of her awards directed toward small business set-asides—equally split between HUBZone and total small business categories under FAR 19.5. This deliberate focus demonstrates her dedication to expanding economic opportunity while enhancing competition. Only 42.9% of her contracts are open to all offerors, underscoring her proactive use of set-asides to empower underserved small businesses in federal service delivery. Roberta’s primary technical domain centers on NAICS 561720 (Janitorial Services), 561730 (Landscaping Services), 722310 (Food Service Contractors), and 541990 (Other Professional Services). She routinely procures facility support services that maintain compliance with ADA, GSA sustainability mandates, and federal building codes, ensuring that federal infrastructure remains functional, accessible, and resilient. Her expertise lies in structuring performance metrics and quality assurance surveillance plans to drive contractor accountability across these critical service lines.
