About this file
This Construction Bulletin No. 1 is issued by the Facility Planning, Construction and Management Division, Design Services and Standards Branch, Architecture and Engineering Section for the Calipatria State Prison (CAL) roof replacement project. The bulletin addresses Project #18-045, which involves replacing roofs for 20 buildings (Buildings 321-355), specifically Buildings 321-345 and Buildings 351-355. The document details revisions to the roof slope, changing it to ¼" per foot and modifying the parallel Air Handling Unit (AHU) crickets to 1½" per foot on the upper roof, as per Request for Information (RFI) 003. The changes impact multiple drawing sheets (GA2.0-GA4.7, HA2.0-HA4.7) and include updates to spot elevations, parapet heights, roof edge conditions, and safety railing details.
The bulletin provides comprehensive technical specifications for the roof replacement, including detailed modifications to existing roof structures, insulation, and architectural elements. The revisions are part of a phased roof replacement project, with specific attention to maintaining proper drainage and structural integrity. The document is approved by Martha Cervantes, Senior Architect, and John Rodriguez, Supervising Architect, with approvals dated July 22, 2024 and July 23, 2024 respectively. The construction bulletin serves as an official modification to previous design documents, ensuring that all contractors and involved parties have the most up-to-date technical specifications for the roof replacement project at Calipatria State Prison.
