James H. Dingeman III

James H. Dingeman III serves as Vice President at the PBS R00 Center for Broker Services within the General Services Administration’s Public Buildings Service, where he oversees the strategic acquisition and leasing of nonresidential real estate to support federal agency workspace needs across the United States. His role centers on executing complex real property transactions, including long-term leases, build-to-suit arrangements, and space optimization initiatives that align with federal footprint reduction goals. Dingeman manages the end-to-end procurement lifecycle for commercial office space acquisitions, ensuring compliance with federal real estate regulations and fiscal accountability while advancing mission-critical facility requirements for federal personnel. He maintains consistent working relationships with a select group of institutional real estate developers and property owners, including TWO CON LLC, ONNI TIMES SQUARE LP, CVD MAIN LLC, BELTSVILLE GSA FDA LLC, and CC OWNER LLC. These partnerships are primarily transactional and focused on large-scale commercial property leasing, with an emphasis on high-quality, Class A office spaces in urban and suburban markets. Dingeman’s contracting approach prioritizes efficiency, market competitiveness, and contractual precision, often engaging landlords with proven experience in GSA lease negotiations and federal compliance standards. Dingeman’s procurement portfolio reflects a strict preference for no set-aside programs, with 100% of acquisitions conducted under full and open competition. This pattern underscores a mission-driven focus on securing optimal space solutions through market-wide competition rather than socioeconomic set-asides, aligning with the Center’s mandate to achieve the best value for federal taxpayers without restriction. His primary procurement focus is concentrated in NAICS 531190 — Lessors of Other Real Estate Property — indicating deep expertise in commercial real estate leasing, property management agreements, and space utilization contracts. He specializes in procuring turnkey leased facilities, including build-to-suit developments, tenant improvement allowances, and long-term lease structures tailored to federal security and operational requirements.
