John Tiner

John Tiner supports the Public Buildings Service’s Pbs R8 Office of Leasing within the General Services Administration, playing a critical role in securing nonresidential real estate to meet the operational needs of federal agencies across the United States. His procurement activities center on leasing office and operational space that complies with federal standards for security, accessibility, and sustainability. He manages the full lifecycle of real property leases—from site identification and negotiation to contract execution and performance monitoring—ensuring alignment with GSA’s mission to optimize federal space utilization and reduce long-term occupancy costs. His work directly enables federal agencies to maintain efficient, compliant, and mission-ready work environments. While specific contractor names are not available, Tiner routinely engages with commercial real estate lessors, property management firms, and real estate advisory services that specialize in federal lease compliance. His contracting patterns reflect a preference for established landlords with experience in federal tenant requirements, including building modernization, ADA compliance, and cybersecurity infrastructure integration. Vendor relationships are typically long-term and performance-based, emphasizing reliability, transparency, and adherence to federal leasing regulations. Tiner’s procurement portfolio shows a 100% preference for non-set-aside contracts, indicating a focus on full and open competition rather than socioeconomic set-asides such as 8(a), HUBZone, or SDVOSB programs. This approach prioritizes market-wide competition to achieve optimal value and space suitability, reflecting the agency’s emphasis on mission-critical outcomes over socioeconomic targets in real estate acquisition. His primary procurement focus is on NAICS 531120—Lessors of Nonresidential Buildings—accounting for nearly 89% of activity, reflecting a strong emphasis on leasing commercial office space. The remaining 11% involves geophysical surveying and mapping services (NAICS 541360), likely for site assessment, boundary analysis, or environmental compliance prior to lease execution. Tiner’s expertise lies in navigating complex real estate markets and ensuring leased facilities meet federal operational and regulatory standards.
