Truebeck Completes County of San Mateo Health Campus

Truebeck proudly announces the completion of the County of San Mateo Health Campus. The ribbon-cutting ceremony and grand opening celebration took place on December 12, 2025. The $176 million project located at 222 W. 39th Street has been years in the making, with planning starting in 2016 and construction beginning in November 2018.
 
The multi-phase Health Campus project spans a full city block, including approximately 200,000sf of sitework, 90,000sf of new ground-up construction, 180,000sf of existing buildings demolished, and 50,000sf of tenant improvements across multiple existing buildings on campus. This highly complex project adopted design-build methodologies and behaviors within a CM-at-Risk framework.

The first phase of work, completed in 2021, included a 12,000sf renovation of the central plant and a 27,000sf nursing wing ground floor renovation, featuring an outpatient rehabilitation clinic, dietary kitchen, café, and servery, all under OSHPD jurisdiction. The second phase delivered a new, ground-up Administration Office Building in 2023. This 52,000sf, three-story building houses administrative and executive staff, as well as the County’s Public Health Lab and Morgue/Coroner.

In the final phase, the project team demolished the 109,000sf “1954 Building” and the 70,000sf Health Services Building. The team constructed the new 35,000sf Link Building, which connects the Administration Office Building to the existing hospital. This phase also included the completion of the relocated, welcoming entrance to the Campus, additional sitework to create more parking, and construction of a new loading dock serving the Central Plant. The interior fit-out of the Link Building was also completed; it features a new cafeteria, engineers’ workshop, and multiple public-facing departments for the Health Campus.

This new campus provides Class A healthcare space for the County of San Mateo. Paul Cunningham, Truebeck Project Executive, stated: “After seven years of hard work, the completion of the San Mateo Health Campus project is a momentous occasion. We could not have done it without all of our partners in design and construction, as well as the collaboration of the hospital staff, patients, and neighbors. This project is a tremendous addition that will help serve the San Mateo community.”Kevin Hinrichs, President of Taylor Design, stated: “Having worked side-by-side with San Mateo County on this complex master planning and design project since 2016, it is thrilling for me and the rest of the Taylor Design team to see this project come to life. It has been especially gratifying to support the County and help them reimagine and update their medical campus so that it continues to best serve the patients, medical teams, staff, and the community into the future.”
