About this file
This document is a mechanical/plumbing roof plan remodel drawing for the California State Prison, Los Angeles County (LAC), specifically targeting Housing Unit Buildings 346 and 347, prepared by Turley Mechanical Engineering & Associates Group and Hibser Yamauchi Architects. The project involves a comprehensive roof replacement and equipment repositioning, with work focused on reinstalling and reconnecting existing mechanical units including air handling units (AHUs), air conditioning units, exhaust fans, water heaters, and associated piping and ductwork. The drawing is dated August 31, 2023, and has received approval from the California Department of Corrections and Rehabilitation's Facility Planning, Construction and Management Division, with fire safety approval obtained on 10/10/23.
The drawing provides detailed technical specifications for repositioning roof-mounted equipment, including requirements for new curb adaptors, flashing, piping reconnections, and duct modifications. Notable technical requirements include field verification of existing equipment details, ensuring proper startup and operation of all systems, and matching existing pipe and fitting materials. The project involves 30 plumbing vent pipes, multiple gas, water, and condensate drain line reconfigurations, and careful preservation of existing infrastructure. The State Fire Marshal has approved the plans, subject to field inspection, with a final approval date of 11/20/2023, indicating this is a carefully regulated state infrastructure improvement project.
