About this file
This document is a structural engineering drawing (Sheet S301) for the California Department of Corrections and Rehabilitation (CDCR) at the California State Prison in Los Angeles County (LAC), located in Lancaster, CA. The drawing is part of a Phase 1 roof replacement project, with the project number 21-040 and design services provided by Hibser Yamauchi Architects, Inc. The specific sheet focuses on detailed structural sections and plans for modifying existing stair cage structures, including steel reinforcement, grating removal and reinstallation, and corrosion mitigation.
The drawing includes technical specifications for steel structural modifications, with specific notes requiring inspection of all steel for corrosion and replacement of members where thickness is reduced by 10% or more. The project is dated August 31, 2023, with approval from the Office of the State Fire Marshal received on 10/10/23. The drawing set includes multiple section views and details for structural modifications, indicating a comprehensive approach to renovating existing infrastructure at the prison facility. The document has been reviewed and approved with a CASp (Certified Access Specialist) number 1317, suggesting compliance with accessibility standards.
