About this file
This document is a roof demolition plan for Buildings 346 and 347 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 a comprehensive roof replacement and demolition effort for two housing unit buildings, with detailed architectural drawings specifying the complete removal of existing roofing systems, mechanical units, walkpads, electrical conduits, and associated roof infrastructure. The plan is dated August 31, 2023, with final drawings marked as version 5843.10, and includes Office of the State Fire Marshal approval received on 10/10/23.
The demolition scope includes specific instructions for removing and potentially reinstalling various roof components such as exhaust fans, vent pipes, guardrails, ladders, and mechanical equipment, with careful provisions for protecting and storing items for potential reuse. The project requires compliance with local, state, and federal codes for construction debris removal, utility protection, and repair. General notes emphasize the need to coordinate with plant operations, inspect fire-retardant treated wood, and ensure all removed and reinstalled components meet safety and functional standards. The drawings provide a comprehensive grid-based plan with detailed demolition legends and keynotes specifying the exact removal and treatment of each roof element.
