Sarah M Andrae

Sarah M. Andrae serves as a key procurement professional within the Public Buildings Service’s R5 Acquisition Management Division, overseeing the acquisition of construction and facility modernization services for federal buildings nationwide. Responsible for managing the full lifecycle of contracts under NAICS 236220, she specializes in commercial and institutional building construction projects, including interior renovations, building systems upgrades, and mission-critical facility support. Her work directly supports the General Services Administration’s mandate to maintain and modernize the federal government’s physical infrastructure, ensuring compliance with federal construction standards and sustainability goals. Andrae routinely handles complex, performance-based contracts requiring rigorous technical evaluation and project oversight. She maintains a consistent working relationship with MCKENZIE CONSTRUCTION & SITE DEVELOPMENT LLC, a primary contractor for interior renovation and facility upgrade projects. Her procurement approach emphasizes long-term vendor partnerships built on reliability, regulatory compliance, and delivery of high-quality construction services. While she engages with a limited pool of pre-qualified contractors, her selection process prioritizes proven performance, safety records, and adherence to federal construction codes, fostering stable, results-driven collaborations. Andrae’s contracting portfolio reflects a strong preference for open competition, with 83.3% of awards issued without set-aside designations. However, she consistently allocates 16.7% of opportunities to Total Small Business Set-Asides under FAR 19.5, demonstrating a deliberate commitment to small business participation without relying on specialized socioeconomic programs like 8(a) or HUBZone. This balanced approach supports broad market access while maintaining competitive rigor. Her technical expertise is narrowly focused on NAICS 236220, encompassing the full scope of commercial and institutional construction—new builds, tenant improvements, HVAC and electrical system retrofits, and ADA-compliant modifications. She possesses deep familiarity with federal construction specifications, building codes, and facility management requirements, ensuring that all procurements align with the Public Buildings Service’s mission to deliver safe, efficient, and sustainable federal workspaces.
