1.2 GENERAL INTENTION

A. The Chiller Infrastructure at the VA Central California Health Care system at 2615 E.

Clinton Ave. Fresno, CA 93703 requires updating, and corrections. This project is to increase the size of the chilled water piping system from the chilled water plant to Building

1 (the Main Hospital Building) to increase the distribution capacity for the main hospital. It also includes the installation of one additional chiller (Chiller 4) in the chiller plant to increase the chilled water capacity for the campus. Additionally, distribution of the chilled water system, and future utility systems, shall be located in overhead duct banks contained within a visually attractive, concealing pedestrian canopy. This necessitates the replacement and expansion of the existing pedestrian canopy system as shown on the drawings. It is noted that hospital operations must not be impacted by this project.

Therefore, an alternate pedestrian route has been identified for temporary or permanent construction depending on Additive Alternate execution. The scope also includes the removal and replacement of manhole/vault #7 along with providing new medium voltage feeders in new concrete duct bank to the new location. Additionally, corner drains will be added manhole/vault 5 and the B24 breezeway concrete floor will be resurfaced.

Contractor shall completely prepare site for building operations, including demolition and removal of existing structures, and furnish labor and materials and perform work for the removal and replacement of the existing pedestrian canopy system, associated infrastructure, chillers, and commissioning as required by drawings and specifications.
