Weiss serves as a Contracting Officer within the Public Buildings Service (PBS R10, Agency Code: 47PL04) under the General Services Administration, where she manages the acquisition of construction and facility modernization services critical to maintaining federal infrastructure. Her portfolio centers on the design, renovation, and upkeep of high-visibility and historic federal buildings, ensuring compliance with federal standards for safety, accessibility, and sustainability.

Her contracting approach emphasizes transparency, competitive bidding, and performance-based outcomes, ensuring accountability across all phases of project delivery. A staunch advocate for socioeconomic equity in federal contracting, Weiss consistently prioritizes small business participation, with over half of her awards designated as total small business set-asides under FAR 19.5. She actively promotes opportunities for Service-Disabled Veteran-Owned Small Businesses (SDVOSBs), Economically Disadvantaged Women-Owned Small Businesses (EDWOSBs), and HUBZone firms, aligning procurement decisions with federal socioeconomic goals. Her patterns reflect a deliberate strategy to expand market access for underserved entrepreneurs while maintaining high performance standards. Her primary procurement focus lies in NAICS 236220 (Commercial and Institutional Building Construction), complemented by significant activity in electrical (238210), flooring (238330), and finishing trades (238390). She specializes in procuring integrated construction services for federal facilities, with deep technical familiarity in historic preservation, energy-efficient retrofits, and building systems integration. Weiss brings a nuanced understanding of federal construction standards and codes, ensuring all acquisitions meet the mission-critical demands of PBS R10’s infrastructure stewardship mandate.
