6.                     Discussion and Background

The provisions of this contract allow for proper maintenance of heating, ventilation, and air conditioning (HVAC) at City facilities and parks. In addition, the contract allows for HVAC equipment to be replaced on an as-needed basis. Due to the nature of aging infrastructure and equipment, Diversified Thermal Services, Inc. made many repairs under the contract. Highlighted below are the most significant emergency repairs and technology upgrades to HVAC in City facilities and parks facilities since February 2019:

                     Repair and replace various parts such as air heating boiler, sensors, motors, variable frequency drive (VFD), worn wiring in the air chiller, and other fan motors at Police Headquarters ($68,937).

                     Replace 5-ton split system in IT Server Room at City Hall ($13,984)

                     Replace two 3-ton package units at the Water Plant ($14,863) and a heater in Fleet Garage ($4,275).

                     Repair and replace various parts such as blower motor, blower wheel, capacitor, drain line, and wiring at Fire Stations 1 and 8 ($5,000).

                     Remove and replace two 3-ton HVAC split systems and a one-ton mini-split unit at Killefer Park and Grijalva Park ($33,425).

                     Upgrade Enteliweb graphics to Hypertext Markup Language (HTML) due to Adobe Flash discontinuation of support Flash Player after December 31, 2020 ($41,984).

Staff recommends approval of the First Amendment to the Agreement, increasing the contract by $150,000 for a total amount not to exceed $610,630, to allow for the maintenance of the HVAC system city-wide through June 2022.
