Shonita L McCaster-Mueller

Shonita L. McCaster-Mueller serves as a Contracting Officer within the Public Buildings Service’s R8 Acquisition Management Division, where she oversees the procurement of critical infrastructure and facility support services for federal buildings and land ports of entry nationwide. Responsible for managing full lifecycle acquisitions under FAR Part 36 and Part 19, she specializes in integrated design-build projects, facility modernization, and operational services contracts that ensure the safety, efficiency, and sustainability of federal infrastructure. Her portfolio includes complex, mission-critical procurements requiring technical coordination between architects, engineers, and construction managers to deliver high-performance facilities aligned with GSA sustainability and resilience standards. McCaster-Mueller maintains consistent working relationships with a core group of contractors, including LEA MARIE LLC, SECURITYHUNTER, INC., MCKENZIE CONSTRUCTION & SITE DEVELOPMENT LLC, and HANDYMAN NATION INC., reflecting a preference for experienced, regionally based firms capable of delivering specialized construction and facility support services. Her contracting patterns demonstrate a focus on long-term vendor partnerships built on performance reliability, compliance with federal construction codes, and responsiveness to dynamic facility needs across multiple geographic regions. Her procurement strategy prioritizes small business participation, with approximately one-third of her awards structured as Total Small Business Set-Asides under FAR 19.5, demonstrating a strong commitment to socioeconomic contracting goals. While no set-asides are designated for 8(a), HUBZone, or SDVOSB programs in her recent portfolio, her consistent use of small business set-asides supports broad-based economic opportunity and workforce development in federal contracting. Her primary procurement focus centers on NAICS 237130 (Power and Communication Line Construction), NAICS 561210 (Facilities Support Services), NAICS 541310 (Architectural Services), and NAICS 236220 (Commercial and Institutional Building Construction). She routinely manages contracts for electrical and communications infrastructure upgrades, preventive maintenance, custodial services, and building renovation projects, requiring deep technical understanding of federal building codes, ADA compliance, and integrated project delivery methods.
