Excerpt_of_2022_CMC.pdf

This is an excerpt from the 2022 California Mechanical Code, Chapter 11, prepared as supporting documentation for a Request for Proposal issued by the County of Sacramento for the Rio Cosumnes Correctional Center (RCCC). The project involves the replacement of twenty packaged gas-electric rooftop HVAC units at Buildings 555 and 570 with individual rooftop chilled water and hot water air handlers paired with a new grade-level chilled water and heating hot water heat pump plant. The design must comply with Chapter 11 of the 2025 California Mechanical Code, which restricts I-3 occupancies from receiving air conditioning from high-probability direct expansion systems. The project will implement an all-electric system and requires full design services.

The document excerpt serves as the technical code reference governing the mechanical system design requirements for the project. No specific pricing terms, response deadlines, site visit information, bidders' meetings, or contract award dates are contained within this particular code excerpt. The code standards referenced establish the mandatory compliance framework for all design submissions, with emphasis on the prohibition of direct expansion air conditioning systems for correctional facility occupancies and the requirement for the proposed chilled water-hot water system alternative.
