Transforming an Occupied Youth Correctional Center
Transforming part of a youth correctional center campus near the City of Stockton into a $700-million intermediate medical and mental-health care facility for patient-inmates within the California state prison system required the mega-resources of four distinct design-build teams. Efficiently providing care for 1,722 adult male inmate-patients at a centralized location is fulfilling the California Department of Corrections and Rehabilitation’s (CDCR) goal of “serving the health care needs of our inmate/patient population in a cost-effective, sustainable, and constitutionally sound manner.” In a staggering 23-month schedule—from conceptual design through construction completion—Bergelectric, led by the Granite/Hensel Phelps Joint Venture, HOK architects, completed the core support facilities that now serve as the backbone of operations for the new California Health Care Facility (CHCF). Bergelectric provided a 12.47kV power distribution system for the entire 144-acre site, and intricately detailed coordination with the secured facilities contractor took place at every step along the way.
One of the most significant aspects of Berg’s role on CHCF-Stockton was the integration of normal and emergency power. Providing an uninterrupted power supply is essential to not only ensuring continuous quality care, but to security—considering that over 1,700 inmate-patients will be housed there. The massive 115kV substation that was installed by Bergelectric crews was the power driving the entire facility. The emergency power generation plant consists of six (6) Diesel Generator Sets composed of Caterpillar® 3516C Generators (rated at 15kV and 2,500kW). 12 megawatts of generator-supplied emergency power was tied into all of the 1.2 million square feet of facilities across the CHCF campus.
Berg’s use of the latest lean building technologies, such as Trimble—a Global Positioning System (GPS)-locating device—enabled pinpoint critical layout that reduced manpower requirements, shortens the duration of Berg’s on-site activities and kept the schedule as lean as possible. One of the primary features of the multi-building complex is a massive 77,281-sf Material Service Center that stores, inspects, clears and tracks every single item being delivered to or leaving the CHCF, including all medications, food, mail and laundry. Additional facilities in the unsecured package include an outside-grounds building, telecommunications/lock-shop building, vehicle sally port, armory and guard towers. CHCF-Stockton included 18 SEL relays. The SEL relays were programmed by an independent testing agency per the settings of the utility and the facility coordination study. The project achieved a LEED Silver Certification.
