The Outpatient Specialty Center (OSC) is a ground up new construction outpatient facility serviced by a joint venture between John Muir Health and UCSF located on the existing John Muir Hospital Campus. The make-ready work consisted of an on grade new employee parking lot with 438 stalls and included a 1 MG Watt solar carport system that will tie into the main campus central plant, demolition and abatement of existing two MOB buildings, critical utility infrastructure relocation and the central utility plant upgrade which includes adding a 2 MW generator. The OSC is three stories, with one below-grade level that connects to the service yard by 125’long below grade pedestrian tunnel and three large LINAC Vaults. The facility 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 which includes 3 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.
