Recommendation: Approve
SUMMARY
On November 1, 2022, the City Council approved a contract with Carrier Corporation in
the amount of $247,605, for the Police Department Chiller Replacement Project. The
terms and conditions of this project have been complied with and the work has been
performed to the satisfaction of the Project Manager, for a total project cost of $247,605.
It is recommended that the City Council accept all work performed by Carrier Corporation
for the Police Department Chiller Replacement Project as complete.
BACKGROUND
The Police Department chiller plant consists of two 112-ton water cooled chillers. The
chillers are responsible for the cooling of the Police Department, lower City Hall, and
upper City Hall. Both chillers were the original equipment installed when the Police
Department was built. The building is now over 19 years old, and the HVAC equipment
is showing its age. The Police Department chillers were serviced every month for proper
operation and any foreseeable repairs.
During the summer months, it was apparent that the facilities were not being properly
cooled. An inspection of the chillers was conducted, and staff found that Chiller 1
developed a freon leak in the piping welded to the chiller barrel. The piping was covered
with insulation and the leak was not physically detected until a freon leak check was
performed. Insulation covering the freon lines was removed and revealed that the weld
connecting the freon line to the barrel had broken due to corrosion over the years. The
line could not be repaired due to the chance of rupturing the tubes inside the chiller barrel.
Chiller 1 was only running at 50% cooling capacity due to the leak. To properly cool the
Police Department, lower City Hall, and upper City Hall, both chillers are required to run
at 100%.

DISCUSSION
On November 1, 2022, the City Council approved a contract with Carrier Corporation for
the Police Department Chiller Replacement Project. There was a 12-month lead time on
the necessary materials. As part of the project, a new chiller and all related piping were
installed at the Police Department. During the installation process, the contractor installed
a temporary trailered chiller plant to provide cooling to the Police Department, lower City
Hall, and upper City Hall. The new chiller is not only more energy efficient but will also
emit less noise to the surrounding area. In addition, the new chiller will help reduce
disruptions to the cooling of the facilities as less maintenance and repair work to the
equipment will be required.
All terms and conditions of the contract have been complied with and the work has been
performed to the satisfaction of the Project Manager. Carrier Corporation completed the
work as defined in the project plans and specifications, in an efficient and timely manner.
ENVIRONMENTAL ANALYSIS
This chiller replacement project was considered a Class 1 exemption as defined in
Section 15301(a) “Existing Facilities” projects of the California Environmental Quality Act
(“CEQA”), which exempts projects involving interior partitions, plumbing, and electrical
conveyances.
FISCAL IMPACT
The Police Department Chiller Replacement Project was not budgeted in the Fiscal Year
2022-23 Capital Improvement Program, as its failure was unforeseen. On November 1,
2022, a budget appropriation from the General Fund Reserve Balance, in the amount of
$247,605, was authorized by the City Council. The total cost for this project is $247,605.
RECOMMENDATION
It is recommended that the City Council determine that this project is exempt under the
California Environmental Quality Act (“CEQA”); and accept all work performed by Carrier
Corporation for the Police Department Chiller Replacement Project as complete.
