The Outpatient Specialty Center (OSC) is a ground-up new construction outpatient facility serviced by a joint venture between John Muir Health and UCSF on the existing John Muir Hospital Campus in Walnut Creek, CA.

The make-ready work consists of an on-grade new employee parking lot with 438 stalls and a 1 MG watt solar carport system that will tie into the main campus central plant, demolition and abatement of two existing MOB buildings, critical utility infrastructure relocation, and the central utility plant upgrade,
which includes adding a 2 MW generator.

The OSC is a three-story building with a 125’-long, below-grade tunnel that connects the parking structure to the OSC. This 155,176-square-foot outpatient center has a structural concrete frame with a 4’/5’ thick MAT foundation and will be wrapped in a façade composed of EIFS, ACM panels, punched aluminum windows, and glass curtain wall systems. The building contains services for Imaging, including three MRI, CT, Pet-CT, and an Oncology program with UCSF, which includes a radiation oncology department with three Varian LINACs, Brachytherapy (HDR), chemotherapy infusion with associated pharmacy, lab and medical-surgical oncology clinics.
