Sean Mangialardo

Sean Mangialardo serves as a key procurement professional within the Public Buildings Service’s PBS R00 Center for Broker Services, operating under the General Services Administration. He specializes in the acquisition and management of nonresidential real estate leases to support federal agency workspace requirements nationwide. His role centers on executing long-term leasing strategies that align with federal footprint optimization goals, ensuring secure, efficient, and cost-effective commercial properties for federal operations. He routinely manages complex real property transactions under the 531120 NAICS category, coordinating with property owners, brokers, and legal teams to secure lease agreements that meet GSA’s operational and fiscal mandates. Mangialardo maintains consistent relationships with a select group of institutional 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 are primarily structured around direct lease negotiations for Class A and mission-critical office spaces in high-demand urban and suburban markets. His contracting approach emphasizes stability, long-term occupancy, and portfolio-scale consolidation, favoring established property holders with proven track records in federal compliance and facility management. His procurement activity reflects a strict focus on full and open competition, with 100% of awards issued under no set-aside conditions. This underscores a strategic preference for maximizing value through broad market competition rather than socioeconomic set-asides, consistent with the scale and complexity of federal real estate needs. There is no indication of reliance on 8(a), HUBZone, SDVOSB, or other small business programs in his current portfolio. Mangialardo’s technical expertise is concentrated in the 531120 NAICS category—Lessors of Nonresidential Buildings—where he procures turnkey commercial office leases, including build-to-suit arrangements, tenant improvements, and energy-efficient facility upgrades. His domain expertise lies in federal real property strategy, lease administration, and compliance with the Federal Property and Administrative Services Act, ensuring all acquisitions meet GSA’s standards for security, sustainability, and operational readiness.
