Resolution authorizing the Mayor and City Clerk to execute an agreement with HGM Associates Inc. for architectural and engineering services in connection with the Central Fire Station Chiller and Electrical Service Replacement, and authorizing the use of American Rescue Plan Act (ARPA) Revenue Loss funds.  Project # BM-23-08

Central Fire Station was constructed in 1972, and a 100 ton chiller using R-22 refrigerant was installed to provide chilled water to the air handlers in the building.  The chiller is past its useful life and is rapidly deteriorating.  Recently, a leak was discovered that cannot be fixed which will eventually lead to a complete failure of the system. In addition, R-22 refrigerant is now obsolete and major repairs or replacements require the system to be updated to handle newer refrigerants, and additional safety features and ventilation must be installed.

A 1000 amp electric service and main distribution panel were also installed in 1972 to provide power for the building.  This equipment is past its useful life and as part of a study performed to determine the best course of action for the City, it was found that the service equipment is no longer supported by the manufacturer.  Any failure in the distribution side of the panel will leave portions of the building without power.  Without a new electrical service, a temporary generator will have to be rented should a failure occur.

This project includes the replacement of the chiller plant which consists of the evaporator, pumps, air cooled condenser and other associated chiller components, the relocation of the chiller from inside the building and on the roof of the building to the ground on the west side of the building, the installation of a glycol loop and heat exchanger to safely bring the chilled water into the building, and the replacement of the 1000 amp electric service and main distribution panel.

It is recommended that both the chiller and service are updated simultaneously to reduce the cost of separate projects that will require the removal of wall and ceiling finishes, removal and re-installation of equipment and disruption to the daily operations for fire station staff and EMA staff.

This project has been added to the CIP and identified as BM-23-08.  The estimated cost of this project is $692,000.

This project is an unplanned emergency repair and we are requesting that ARPA Revenue Loss funds be utilized for this project. 

HGM partnered with Engineering Technologies Inc. was selected based on their previous involvement with the evaluation and repair study for the chiller, and their successful project history with building modification projects for the City.  They have a clear understanding of the project scope, and the qualified staff available to dedicate to the project.  

Approval of this resolution to enter into an agreement with HGM for architectural and engineering services, and to authorize the use of ARPA Revenue Loss funds.
