About this file
This document is a roof demolition plan drawing for a California State Prison project located in Lancaster, California, prepared by the State of California Department of Corrections and Rehabilitation's Facility Planning, Construction and Management Division. The drawing specifically details the demolition plan for a Typical 270 Housing Unit Roof, covering multiple buildings (Buildings 331-349 and 3310), with the project dated August 31, 2023. The plan includes comprehensive demolition legends and keynotes describing the systematic removal of existing roofing components, mechanical units, walkpads, electrical conduits, guardrails, and other roof-related infrastructure, with specific instructions for handling and protecting existing equipment during the renovation process.
The document indicates this is a phased roof replacement project, with meticulous attention to preserving and reinstalling existing equipment where possible. Key demolition requirements include removing existing built-up roofing systems, rigid insulation, counter flashing, and penetration flashings, with provisions for patching and repairing the existing metal deck with lightweight concrete topping. The plan emphasizes compliance with local, state, and federal codes, and includes specific instructions for debris removal, utility protection, and coordination with plant operations. The project has received approval from the Office of the State Fire Marshal on 10/10/23, with a final approval date of 11/20/2023, suggesting the project is in its final planning and preparation stages.
