About this file
This document is a set of demolition and roof replacement plans for Facility A 270 Housing Unit Building 334 at California State Prison, Los Angeles County (LAC), prepared by the State of California Department of Corrections and Rehabilitation's Facility Planning, Construction and Management Division. The project involves comprehensive roof demolition and replacement for a housing unit building located at 44750 60th Street in Lancaster, California, with detailed plans showing complete removal of existing roofing systems, mechanical units, walkpads, electrical conduits, and associated infrastructure. The drawings are dated August 31, 2023, with final approval from the Office of the State Fire Marshal received on 10/10/23, and include specific demolition keynotes and equipment legends detailing precise removal and potential reinstallation procedures.
The project scope includes systematic deconstruction of existing roof elements while preserving critical infrastructure, with specific instructions for handling mechanical units, electrical systems, and structural components. Contractors are required to remove construction debris in compliance with local, state, and federal regulations, protect existing building elements, and coordinate closely with facility maintenance. The demolition plan emphasizes careful dismantling and potential reuse of existing equipment, with particular attention to safety, utility protection, and preparing the site for new roofing installation. The drawings provide granular details about slope management, equipment removal, and restoration procedures, indicating a methodical approach to facility infrastructure renewal.
