About this file
This architectural detail sheet is part of the final drawings for a roof replacement project at the California State Prison, Los Angeles County, prepared by the California Department of Corrections and Rehabilitation's Facility Planning, Construction and Management Division. Located at 44750 60th Street West in Lancaster, California, the project involves replacing roofs in Phase 1, with design documentation dated August 31, 2023. The drawings specifically provide technical details for roofing components including water heater mounting, metal coping on concrete curbs, parapet configurations, and roofing assembly specifications.
The document includes technical engineering drawings with precise measurements and installation instructions for various roofing elements, featuring new PVC membrane roofing, flashing, metal coping, and specific mounting details for water heater tanks. The drawings have been approved by the Office of the State Fire Marshal, with approval noted on 10/10/23 and a final approval date of 11/20/2023. The project drawings are part of design services and standards for a state correctional facility roof renovation, with meticulous attention to waterproofing, insulation, and structural integration of new roofing components.
