Webb, Public Works Director- (949) 644 -3330, dawebb@newportbeachca.gov PREPARED BY: Fong Tse, Assistant City Engineer PHONE: (949) 644 -3321 TITLE: Police Facility HVAC Replacement Project- Completion and Acceptance of Contract No. 5542 (CAP14 -0003) ABSTRACT: At the May 13, 2014 regular meeting, City Council awarded the Police Facility HVAC Replacement Project Contract No. 5542 to K +J Air Conditioning, Inc. for a total contract amount of $268,012.00. This work is now complete and staff requests City Council acceptance and close out of the contract. RECOMMENDATION: a) Accept the completed work and authorize the City Clerk to file a Notice of Completion for the project; b) Authorize the City Clerk to release the Labor and Materials Bond 65 days after the Notice of Completion has been recorded in accordance with applicable portions of the Civil Code; and c) Release the Faithful Performance Bond one year after this Council acceptance. FUNDING REQUIREMENTS: Funds for the construction contract were expended from the following account: Account Description Account Number Amount Facilities Maintenance 7480- C1002014 $ 294,612.00 Total: $ 294,612.00 M DISCUSSION: Overall Contract Cost /Time Summa The contract has now been substantially completed to the satisfaction of the Public Works Department. A summary of the contract cost is as follows: Original bid amount: $ 268,012.00 Actual cost of bid items constructed: $ 268,012.00 Total change orders: $ 26,600.00 Final contract cost: $ 294,612.00 Prior to this project, twenty -nine of the thirty -one 20 -year old packaged heating, ventilation, and air conditioning (HVAC) units atop the Police Facilities were in poor condition and required frequent repairs. In addition to the recurrent mechanical issues, these former units were designed with outdated technology and were costly to operate. During the course of the work, it was brought to the Project Manager's attention by Police facility staff that two HVAC units that were originally designated to remain and continue to serve the Police Department's computer systems were inadequately cooling the computer server room. After further review it was found that both unit's condensers and coils had now deteriorated to a point where costly repairs would be needed within the next year. Upon considering the different repairs vs. replacement options and pricing, the project team determined that these two units should be included within this project now as a change order to take advantage of the reduced mobilization, crane, and equipment costs available through this capital Improvement project, rather than addressed at a later date. The final construction contract cost, including a 5 -year parts and labor extended warranty, was 9.92 percent above the original contract amount due to a contract change order in the amount of $26,600.00 for additional equipment replacement. A summary of the project schedule is as follows: Estimated Completion Date per 2013 Baseline Schedule 8/26/2014 Estimated Project Award for Construction 5/27/2014 Actual Project Award 5/13/2014 Contract Completion Date Per Notice To Proceed 8/22/2014 Actual Substantial Construction Completion Date 10/16/2014 M Actual Awarded Final Cost at Contingency % Due to % Due to Contract Completion Allowance Contract Directed Unforeseen Amount Change Change Change $268,012.00 $294,612.00 10% or less 9.92% 9.92% 0% Actual Time Allowed Contract Time (days) 1s -1 14 The contract has now been substantially completed to the satisfaction of the Public Works Department.

A summary of the project schedule is as follows: Estimated Completion Date per 2013 Baseline Schedule 8/26/2014 Estimated Project Award for Construction 5/27/2014 Actual Project Award 5/13/2014 Contract Completion Date Per Notice To Proceed 8/22/2014 Actual Substantial Construction Completion Date 10/16/2014 M Although the Contract Specifications provided K +J with fifteen (15) consecutive working days to complete all of the work, staff was made aware shortly after the project award that (1) Carrier, the equipment manufacturer, would not be able to deliver the non -stock units until at least two months after the order was placed and (2) the special coatings specified on all of the new condensers and coils for our salt -air operating environment would require an additional four weeks of shop time. Consequently, staff instructed K +J to replace the units in batches as they become available, with the least amount of interference to the Police Department's operations. As such, K +J completed the installation over four weekends for a total of fourteen (14) working days. The existing equipment analyses, replacement equipment specifications, and the construction inspection, testing, and commissioning of the new units were provided by Glumac, Inc. under separate contract for an amount of $17,900. ENVIRONMENTAL REVIEW: The Project was determined to be exempt from the California Environmental Quality Act ( "CEQA ") pursuant to Section 15302 (Replacement or Reconstruction) of the CEQA Guidelines. This Exemption covers the replacement or reconstruction of existing facilities where the new improvements will be located on the same site as the facilities replaced and will have substantially the same purpose and capacity as the facilities replaced. NOTICING: The agenda item has been noticed according to the Brown Act (72 hours in advance of the meeting at which the City Council considers the item).
