Tammy Tran

Tammy Tran serves as a procurement specialist within the California Department of Transportation, supporting the agency’s mission to deliver safe, efficient, and resilient transportation infrastructure. In her role, she manages the acquisition of goods and services critical to highway, bridge, and civil engineering projects, with a focus on transportation equipment, construction services, and facilities support. Her responsibilities include soliciting bids, evaluating proposals, and ensuring compliance with state and federal procurement regulations. She plays a key part in translating Caltrans’ strategic infrastructure goals into actionable contracting actions, ensuring timely delivery of mission-critical resources across the state’s vast transportation network. Tran collaborates with a broad range of contractors, primarily merchant wholesalers of transportation equipment, heavy civil construction firms, and facilities support service providers. While no single vendor dominates her portfolio, she routinely engages with firms experienced in delivering specialized infrastructure materials, such as traffic control systems, signage, and structural components, as well as contractors with proven track records in highway and bridge construction. Her working relationships emphasize technical capability, regulatory compliance, and performance reliability over vendor size or brand recognition. Her contracting patterns reflect a strong preference for open competition, with 100% of her acquisitions conducted without set-asides for 8(a), HUBZone, SDVOSB, or other socioeconomic programs. This indicates a focus on selecting the most qualified proposers based on technical merit and operational readiness, rather than socioeconomic criteria. While small business participation is not formally prioritized in her portfolio, vendors of all sizes are evaluated on equal footing under full and open competition standards. Tran’s procurement focus centers on NAICS 423860 (transportation equipment wholesale), NAICS 237310 (highway, street, and bridge construction), and NAICS 236220 (commercial and institutional building construction). She regularly procures specialized infrastructure materials, construction services for roadway and structural projects, and related facilities support such as maintenance and logistics coordination. Her expertise lies in the technical and logistical demands of large-scale civil engineering procurement, ensuring alignment with Caltrans’ engineering standards and environmental compliance requirements.
