ITEM #15 CITY OF COLTON AGENDA REPORT FOR THE CITY COUNCIL MEETING OF MARCH 20, 2007 TO: HONORABLE MAYOR AND CITY COUNCIL MEMBERS FROM: AMER JAKHER, P.E., PW DIRECTOR/CITY ENGINEER SUBJECT: AUTHORIZE SUBMITTAL AND FILING OF A NOTICE OF COMPLETION FOR THE PD HVAC REPLACEMENT PROJECT. DATE: MARCH 8, 2007 BACKGROUND: On June 7, 2005, the City Council authorized awarding the construction agreement for the P.D. HVAC Replacement Project to Pardess Air, Inc. in the amount of $180,000. Thereafter, two change orders have been taken before Council for approval. On December 20, 2005, Council approved change order number one, which totaled $55,615.00. Change order number one furnished and installed three additional HVAC units for the PD Gym; two of these units were 7.5 ton units and one was a two ton unit. A second change order was approved by Council action on April 17, 2006 for furnishing and installing a four -ton heat pump for the PD Conference Room and extending the Energy Management System (EMS) to PD's mini -gym; the total amount of change order number two was $28,050. ANALYSIS/DISCUSSION: A third and final change order was needed to complete repairs to the existing exhaust fans, electrical connections and variable temperature system. In addition, the condensation drains for the HVAC units were installed above the roof due to accessibility problems, rather than inside the ceiling as was stated in the agreement. Therefore, Change Order No. 3 will also reflect a $1,000 decrease from the awarded compensation. The net change reflected in Change Order No. 3, attached as Exhibit A, is $4,934.47. Approval of Change Order No. 3 will bring the total compensation of the corresponding agreement to $268,599.47. The inspection and air balance test were conducted in the presence of the City -hired consultant Leonard Engineering, LLC and the results were satisfactory. The contractor has provided a short training for the City's maintenance crew regarding operation and repair of the HVAC units and the control system. As -built drawings and operation manuals have been provided to the City depicting the new HVAC System. The HVAC Replacement Project has been completed satisfactorily by the contractor; staff requests authorization to file a notice of completion for this project.
