About this file
This document is a detailed architectural drawing set for a roof replacement project by the California Department of Corrections and Rehabilitation (CDCR) at the California State Prison, Los Angeles County (LAC) located in Lancaster, California. The project, labeled as "Replace Roofs - Phase 1", involves comprehensive roof renovation work including multiple detailed technical specifications for roof transitions, guardrails, roof hatch safety rail guards, plumbing access doors, and catwalk modifications. The drawings are dated August 31, 2023, with final approval from the Office of the State Fire Marshal received on 10/10/23 and 11/20/2023.
The architectural drawings provide precise technical specifications for roof system upgrades, including PVC roofing assemblies, metal flashing, concrete wall interactions, guardrail installations, and safety infrastructure modifications. The project appears to be focused on upgrading and standardizing roof systems and safety features at the correctional facility, with detailed engineering drawings showing precise measurements, material specifications, and installation techniques for various roof and structural elements. The drawings indicate a comprehensive approach to roof replacement that considers existing structural conditions, safety requirements, and technical integration of new roofing systems with existing facility infrastructure.
