About this file
This is a reference project design document for the County of Sacramento's Rio Cosumnes Correctional Center (RCCC) Central Chilled Water Plant project. The document consists of 95% construction documents that were abandoned before completion and are provided as a reference guide for proposing consultants on the forthcoming contract award. The project involves replacing twenty (20) rooftop HVAC units with a new hydronic system utilizing chilled water coils and unit-level gas heating, with a new HVAC plant to be located between buildings 550 and 570. The design incorporates new rooftop air handlers connected to a centralized chilled/hot water plant at the same location shown in the reference plans, utilizing the same electrical pathway. The technical drawings include partial roof plans, electrical remodels, site and roof plans, one-line power diagrams, and AC unit connection details, all prepared by AC - IS C A Engineering Consultants, Inc. with project management by Stuart Lindsay, dated November 19, 2021.
The reference design demonstrates the County's intention to replace the existing packaged gas-electric rooftop units 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 electrical infrastructure includes connections to existing main switchboards (MSA and MSB), emergency switchboards (EMSA and EMSB), and distribution panels with 277/480 volt, 3-phase, 4-wire systems. The document specifies that contractors must locate existing utilities along the new raceway path, note traffic-rated areas, and coordinate all grounding and electrical requirements per California Electrical Code standards. This reference design provides proposing consultants with the technical foundation and electrical pathway information necessary for developing designs compliant with Chapter 11 of the 2025 California Mechanical Code for the upcoming all-electric system implementation.

Attachment H - Reference Project Design - abandoned at 95%CD (page 1 of 4):
Background:
This project design incorporated a chilled water only Hydronic plant with new rooftop air handlers using chilled water coils and unit level gas heating.
The proposed design on the forthcoming contract award will locate the chilled/hot water plant at the same location as shown in this set, and utilize the same electrical pathway.
This set of plans showcases to the proposing consultant that the county wishes to replace these 20 rooftop HVAC units and locate a new HVAC plant between buildings 550 and 570.
