About this file
This document is a detailed roof remodel plan for Facility A 270 Housing Unit Building 334 at California State Prison, Los Angeles County (LAC), prepared by the California Department of Corrections and Rehabilitation's Facility Planning, Construction and Management Division. The project involves replacing roofs in Phase 1, with the final drawings dated August 31, 2023, and includes comprehensive roof renovation work for a 270 Housing Unit building located at 44750 60th Street, West in Lancaster, California. The roof remodel encompasses multiple key elements including installing a new 80 mil fully-adhered PVC roofing system with rigid insulation, replacing roof penetration flashings, reinstalling mechanical units, adding walkpads, extending parapets, and addressing various utility and infrastructure components.
The project scope includes specific technical requirements such as removing existing mechanical units, vents, and fans, protecting electrical systems, replacing conduit and pipe supports, and ensuring compliance with local, state, and federal codes and regulations. The drawings indicate precise measurements, slope specifications, and detailed remodeling legends with specific keynotes for each renovation aspect. The project has received approval from the Office of the State Fire Marshal on 10/10/23 and includes a Certified Access Specialist (CASp) certification, suggesting careful attention to accessibility and safety standards. The roof remodel appears to be part of a broader infrastructure improvement initiative for the correctional facility, focusing on maintaining and upgrading critical building systems.
