Shontise C Mangham

Shontise Mangham serves as a key procurement professional within the PBS R4 Office of Leasing, part of the General Services Administration’s Public Buildings Service, where she manages the acquisition of nonresidential real estate assets to support federal operations across the Southeastern United States. Her role centers on executing strategic leasing contracts that align with mission-critical space requirements, ensuring cost-effective, long-term solutions that enhance operational efficiency and agency readiness. She primarily handles real property lease acquisitions under the Federal Property and Administrative Services Act, with a focus on securing turnkey office, administrative, and ancillary facilities through competitive and non-competitive contracting methods. Mangham maintains established relationships with core contractors including CROWN LEASING INC and FINCANTIERI MARINE REPAIR LLC, reflecting a preference for experienced real estate lessors and specialized facility operators with proven capacity in federal leasing environments. Her contracting patterns indicate a reliance on repeat vendors with demonstrated performance in managing complex lease structures, including build-to-suit, tenant improvement allowances, and long-term occupancy agreements. These partnerships are typically formed through formal solicitations under FAR Part 17 and are aligned with GSA’s real estate consolidation goals. Her procurement portfolio reflects minimal use of socioeconomic set-asides, with 94.2% of awards issued as unrestricted, indicating a primary emphasis on competitive open competition. The remaining 5.8% are awarded under 8(a) competed programs, suggesting selective but deliberate engagement with small disadvantaged businesses when market conditions or facility requirements align with 8(a) capabilities. Her technical expertise is concentrated in NAICS 531120 (Lessors of Nonresidential Buildings), which accounts for over 93% of her activity, demonstrating deep specialization in commercial office and institutional space leasing. She also occasionally procures parking and ancillary real estate services under NAICS 812930 and 531190, reflecting a comprehensive approach to mission-supporting real property acquisition across the Southeast.
