Karen Robertson

Karen Robertson serves as a Senior Transaction Manager at the PBS R00 Center for Broker Services under the General Services Administration’s Public Buildings Service, where she leads the acquisition and leasing of nonresidential real estate to support federal agency workspace requirements. Her role centers on executing complex real property transactions, including long-term leases and space optimization initiatives, to ensure efficient, secure, and cost-effective federal footprints across the United States. She manages end-to-end procurement processes—from market research and solicitation development to contract award and performance oversight—specializing in commercial office space acquisitions that align with federal real property strategic goals. Karen maintains established relationships with a core group of commercial real estate owners and developers, including TWO CON LLC, ONNI TIMES SQUARE LP, CVD MAIN LLC, BELTSVILLE GSA FDA LLC, and CC OWNER LLC. These partnerships reflect a consistent focus on high-demand urban and suburban office properties, with an emphasis on mission-critical locations that accommodate federal tenant needs. Her contracting approach prioritizes stability, compliance, and operational continuity, often resulting in multi-year lease agreements with repeat vendors who demonstrate reliability in property condition, lease administration, and regulatory adherence. Karen’s procurement portfolio is exclusively non-set-aside, with 100% of awards issued under full and open competition. This reflects a strategic alignment with the agency’s mandate to secure optimal space at market rates without socioeconomic set-asides, ensuring the most cost-effective outcomes for federal taxpayers while maintaining competitive rigor in vendor selection. Her primary procurement focus is NAICS 531120—Lessors of Nonresidential Buildings (except Miniwarehouses)—indicating deep expertise in commercial real estate leasing, property condition assessments, and lease negotiation frameworks. She specializes in procuring turnkey office environments, including build-outs, common area maintenance, and utility infrastructure, with an emphasis on energy efficiency, security compliance, and ADA accessibility standards.
