Public Works Agency <br />www.santa-ana.org/pw <br />Item # 15 <br />City of Santa Ana <br />20 Civic Center Plaza, Santa Ana, CA 92701 <br /> Staff Report <br />March 15, 2022 <br />TOPIC: Replace Air Conditioning Unit at the Ross Annex <br />AGENDA TITLE <br />Award a Purchase Order in an Amount Not to Exceed $323,827 to Trane U.S. Inc., dba <br />Trane for Replacement of an Air Conditioning Unit in the Ross Annex Portion of City Hall <br />(Specification No. 22-024) (General Fund) <br />RECOMMENDED ACTION <br />Award a purchase order to Trane U.S. Inc., dba Trane in the amount of $281,589, with a <br />contingency amount of $42,238, for a total amount not to exceed $323,827, to replace an <br />air conditioning unit at the Ross Annex, subject to non-substantive changes approved by <br />the City Manager and City Attorney. <br />DISCUSSION <br />The Public Works Agency’s Building Maintenance Division oversees City facilities to <br />ensure mechanical systems operate safely and efficiently, and meet all applicable laws <br />and regulations. The commercial-grade rooftop heating, ventilation, and air conditioning <br />(HVAC) system at the Ross Annex contains three air conditioning units. Two of the three <br />units were replaced in the past 2 years, after 22 years of service. The remaining air <br />conditioning unit is frequently out of order, requires continuous repairs, and operates at <br />50 percent capacity. As such, staff recommends replacing the unit. <br />The existing unit is manufactured by Trane and staff seeks to replace it with a unit <br />produced by the same manufacturer, as it will provide a seamless transition, given that <br />the current support system already accommodates the weight, size, and location of the <br />new unit. Utilizing equipment from a different manufacturer could result in a change in <br />size, weight, and location of supports and connection points, requiring additional <br />engineering, structural, and mechanical modifications. Such modifications would <br />significantly increase the cost and add a significant amount of time to the replacement <br />schedule. <br />Santa Ana Ordinance No. NS-2312 authorizes the City to purchase against contracts from <br />any public agency employing a competitive bid process. Harford County Public Schools <br />awarded a contract to Trane U.S. Inc. (Contract No. RFP #15-JLP-023) for the <br />procurement of comprehensive HVAC products, installation, services and related <br />products and services. The contract was awarded as a result of open, competitive
