The California Health Care Facility (CHCF) located in Stockton, CA is an intermediate-level medical and mental health care facility for patient-inmates within the California state prison system. By centrally locating inmates with the highest level of medical and mental health care needs in a facility such as this, the state is able to provide health care to its incarcerated population in a more cost-effective and efficient manner. Siegfried, working under HDR Engineers, provided the mass grading plan and pavement detail designs for the entire “inside the fence package” of the project which consists of 1.2 million square feet of building space with over 1,700 medical beds. The facility also includes diagnostic and treatment centers, a 13-foot tall lethal electrified fence, and eleven 45-foot tall guard towers. The entire project construction cost is in excess of $700 million dollars.
