Shirley A. Turnbo

Shirley A. Turnbo serves as a Contracting Officer for the U.S. Army Corps of Engineers’ W075 Endist San Francisco district, where she manages complex civil infrastructure acquisitions aligned with the Department of the Army’s mission to safeguard and enhance national water resources. Her portfolio centers on heavy civil engineering projects, including flood control systems, dam safety upgrades, levee construction, and beneficial use of dredged material. Turnbo oversees the full lifecycle of contracts—from solicitation and source selection to award and closeout—ensuring compliance with federal regulations, environmental statutes, and public works standards. She plays a pivotal role in delivering mission-critical infrastructure that supports resilience, sustainability, and public safety across federal water resource sites. Turnbo maintains longstanding relationships with leading contractors in the civil works sector, including BFBC LLC, Granite Construction Company, Manson Construction Co., McKenzie Construction & Site Development LLC, and the CAM-DUTRA JV-II LLC. These partnerships reflect a preference for experienced, vertically integrated firms capable of executing large-scale earthwork, hydraulic structures, and environmental remediation tasks. Her procurement approach emphasizes technical competence, past performance, and safety compliance, fostering collaborative relationships with contractors who demonstrate proven expertise in federal civil works environments. While the majority of her acquisitions are unrestricted, Turnbo consistently allocates approximately 25.5% of her portfolio to Total Small Business Set-Asides under FAR 19.5, demonstrating a deliberate commitment to small business participation. She prioritizes socioeconomic programs that enable qualified small businesses to compete for civil engineering and environmental services contracts, though she does not routinely utilize 8(a), HUBZone, or SDVOSB set-asides, reflecting a broader focus on general small business eligibility. Her primary procurement focus lies in NAICS 237990 (Other Heavy and Civil Engineering Construction), which accounts for over 40% of her activity, supplemented by engineering services (541330) and environmental consulting (541620). She routinely procures design-build, construction management, and environmental remediation services, demonstrating deep technical expertise in hydraulic structures, dredging operations, and sustainable infrastructure development.
