San Quentin Central Health Services Building (Design-Build) |
|
|
|
Crosby Group provided structural design solutions for the new 5-story 116,000 square foot Central Health Services building located within the secure perimeter of San Quentin State Prison. Tasked with reforming the State’s healthcare infrastructure, the California Prison Healthcare Receivership Corporation decided to develop the Central Health Services building at San Quentin as a prototype facility for the rest of the prison system. This state-of-the-art facility includes a receiving and release center to process the overall health of incoming and outgoing prisoners, as well as medical, dental and mental health evaluation and treatment functions for the entire prison population. The fifth floor provides administrative spaces for the professional staff working at the facility and provides training rooms and conference spaces that overlook Mount Tamalpais. The structural steel design included the use of both moment resisting frames to provide the required open spaces necessitated by program requirements, and braced frames to provide a cost-effective solution where they could be accommodated. And all inmate accessible areas were required to have hardened surfaces meeting the security requirements of CDCR. A 3-D Revit model was successfully developed and used to coordinate the existing and new elements of construction, as well as for inter-disciplinary coordination.
Particularly challenging was the preservation of key elements of the existing structure requested by the State Historic Preservation Office. Initial design included the demolition of an existing multi-story unreinforced masonry structure while maintaining and retrofitting an existing 25 foot high unreinforced masonry retaining wall. The program also mandated the inclusion of a 2-story unreinforced masonry “Hospital” façade wall dating back to 1885, which required significant structural strengthening and connection to the new building, yet was isolated with seismic slider pads from the existing retaining wall structure. Additionally, an 1850’s-era stone walled Dungeon, which was enveloped in the previous building, was exposed, preserved and retrofitted without altering its historic fabric. Crosby Group solutions not only ensured that the design, program and schedule requirements would be met, but that the solutions were also cost-effective, historically sensitive, and OSHPD-compliant.
