RECOMMENDATIONS: That the Board of Public Utilities: Reject the bids received from Redline Air, Inc. and GM Climate Control, Inc. as non - responsive; 2. Award a contract for the construction of the HVAC system at the Utilities Operations Center, Bid No. 7254 to the lowest responsive bidder, Eberhard SMC, of Van Nuys, California, in the amount of $235,295; and 3. Approve the capital expenditure of $334,409 for Work Order No. 1319978 which includes the purchase, installation, new gas line with Southern California Edison and 10% change order contingency for the HVAC system at the Utilities Operations Center, Bid No. 7254. BACKGROUND: In October 2010, the Board of Public Utilities approved the replacement of the aging Heating, Ventilation and Air - conditioning (HVAC) system at the Utility Operations Center (UOC). During the modernization, staff discovered that the computer room, the battery room and the IT room lacked emergency shut -off redundancy. Because the UOC houses essential equipment for daily and emergency operations, a redundant HVAC system is required to move excessive heat loads away from the building during the event of a systems failure. The UOC HVAC Redundancy, Phase 2 project proposes to install three new Mitsubishi ductless split systems in several critical areas of the facility. Additional air conditioning will be added to the Battery/Electrical Room, Telephone /Radio Room, Fiber Optic Room and Computer Server Room. Each of the new installations will provide adequate cooling capacity to carry heat loads in the designated areas in the event of a failure of the existing cooling system. In the Computer Server Room, new units will act as the primary cooling source, while the existing system will become the redundant back up cooling device. The project also includes the installation of a new exhaust fan in the Battery/Electrical Room, and the installation of a new natural gas service connection which is required for the existing Chiller Plant. A comprehensive bid package was issued in July 2014; four contractors bid on the project. The lowest responsive bid was submitted by Eberhard SMC. Staff has reviewed documentation and has determined Eberhard SMC has met all of the requirements of the specifications.
