About this file
This document is a detailed roof remodeling plan for the 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 for multiple housing units (Buildings 331-345 and 348-3410) in Phase 1 of a roof replacement initiative. The plan, dated August 31, 2023, with final drawings approved on 10/10/23 by the Office of the State Fire Marshal, includes comprehensive technical specifications for a complete roof system renovation, including installing 80 mil fully-adhered PVC roofing, new metal coping, parapet extensions, walkpads, and reinstallation of existing mechanical equipment.
The project site is located at 44750 60th Street, West, Lancaster, CA 93536, and involves extensive roof infrastructure upgrades across multiple prison housing units. Key technical details include installing new Class A UL 790 rated roofing systems with protection board and rigid insulation, replacing roof penetrations, reinstalling existing mechanical units on new raised curbs, adding guardrails, roof hatches, and walkpads, and extending parapets. The drawings include specific notes about debris removal, utility protection, coordination with plant operations, and compliance with local, state, and federal codes. The plan has received accessibility certification (CASp 491 #1317) and fire safety approval, indicating comprehensive regulatory compliance for this state corrections facility infrastructure project.
