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 $318,645. It is recommended that the City Council accept all work performed by Carrier Corporation for the Library Chiller Replacement Project as complete. BACKGROUND The Fiscal Year 2019-20 Capital Improvement Program (“CIP”) included the replacement of the 110-ton water-cooled chiller and controller at the Arcadia Public Library. The water- cooled chiller is responsible for providing cooling to most of the Library building. Over time, the chiller began presenting numerous maintenance issues, with costly repairs needed for the compressors that operate the water-cooled chiller. To extend its lifecycle as long as possible, to keep costs down during a period of economic uncertainty, and to keep staff and the public safe during the pandemic, this project was placed on hold. The water-cooled chiller had outlived its useful life and the compressors on the chiller were beginning to fail. The Arcadia Library Chiller was operating on only three of its four compressors and replacing it became imperative to ensure the facility was properly cooled, especially considering the Library is a designated cooling center for the City. Furthermore, in addition to the limited supply of conditioned air, the chiller was charged with R-22 refrigerant, which has become restricted by South Coast Air Quality Management District (“AQMD”). A new Modular Chiller operating on R-410A freon refrigerant was needed as a replacement to comply with AQMD requirements. Accept Library Chiller Replacement Project October 15, 2024 Page 2 of 2 DISCUSSION On October 4, 2022, the City Council approved a contract with Carrier Corporation for the Library Chiller Replacement Project. The work included the replacement of the chiller and all related piping, which was completed within six weeks. As part of this contract, a temporary trailered chiller unit was utilized to provide cooling for the facility while the replacement of the chiller was completed. The new chiller system is Title 24 compliant, is energy efficient, and operates on an R-410A freon refrigerant that meets AQMD requirements. All terms and conditions of this 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 project was considered a Class 1 exemption as defined in Section 15301(d) “Existing Facilities” projects of the California Environmental Quality Act (“CEQA”), which exempts projects consisting of the repair and maintenance of existing public structures. FISCAL IMPACT Funds in the amount of $150,000 were budgeted in the Fiscal Year 2019-20 CIP for the Library Chiller Replacement Project. Due to major construction and material cost increases incurred since the project was originally budgeted, a supplemental budget appropriation was authorized by the City Council on October 4, 2022, in the amount of $168,645. The supplemental budget plus the original budget results in total funds in the amount of $318,645, which is the total cost for this project. 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 Library Chiller Replacement Project as complete.
