Agenda 03/27/2018 Item #16D 903/27/2018 EXECUTIVE SUMMARY Recommendation to approve Change Order #6 for Contract 15-6437 Vanderbilt Beach Utility Conversion Services with MasTec, Inc. to increase the contract amount by $460,904.27 with a revised completion date of December 1, 2019, for the Vanderbilt Beach Municipal Services Taxing Unit (MSTU) Utility Conversion Project Phase II and III, due to the coordination efforts with the Water, Sewer, and Stormwater replacement project in the same. OBJECTIVE: To provide continuous construction services with MasTec, Inc., for the Vanderbilt Beach Aerial to underground Utility Conversion project. CONSIDERATIONS: The Board of County Commissioners (Board) awarded Contract 15-6437 to MasTec. on July 7, 2015 (Agenda Item 16D6) as an approved Florida Power and Light Co. (FPL) contractor to install and activate the utility network conversion from aerial to underground for Phase II and III Vanderbilt Beach MSTU Utility Conversion Project at a cost of $574,606.25. On March 9, 2017, FPL accepted the As-Built construction prints for Phases II and III of the Vanderbilt Beach Aerial to Underground Conversion Project. With the approval of the as -built plans, staff directed MasTec to mobilize and prepare for activation by April 1, 2017. With an April 2017 mobilization, it was anticipated that the activation of both phases would be completed by December 1, 2017. However, a water and sewer line replacement project conducted by the Public Utility Department (PUD) situated in the same area and scheduled to begin during the FPL aerial conversion project activation period raised concerns for the safety of the workers on the water/sewer line replacement project. As a result, staff determined it would be best to delay activation of the FPL network for Phase II and III. Through cross project coordination with the County Managers office, PUD, and the Public Transit & Neighborhood Enhancement Division (PTNE), it was agreed that activation of the FPL Network would be sequenced with the Utility project and following the completion of the phases of the PUD project (delayed until May 2018). This delay will result in added cost to: 1) test the network to find damages; 2) to repair any possible damages to the network during the PUD construction project ; and 3) to replace equipment that experiences deterioration because of the time installed on the project before activation. The added cost for the task required due to the delay will be absorbed by PUD, subject to post-audit. Change Order #6 reflects estimated increased costs for MasTec to fully repair all damage and complete the installation and activation of the FPL network already in place and ready to be activated. MasTec has requested an increase in the unit costs of several line items to reflect the change in construction conditions due to the PUD project. The change order also reflects the cost of construction services now required for re-phasing the FPL burial project to accommodate the PUD Project. MasTec has been required to delay their schedule for almost two (2) years. The Vanderbilt Beach MSTU Advisory Board voted to recommend approval of this modification by a vote of 5-0 on March 1, 2018. Staff has reviewed requests, compared it to earlier bid items, and similar work within the contract and feels that unit price increase i s reasonable for the work being done. MasTec is one of the few FPL contractors that have the capability of doing the work on the project. FISCAL IMPACT: Funds in the amount of $460,904.27 to cover the additional cost for this work until the final determination of reimbursement is completed are available within the Vanderbilt Beautification MSTU Fund 143. GROWTH MANAGEMENT IMPACT: There is no impact on the Growth Management Plan. 16.D.9 Packet Pg. 1252 03/27/2018 LEGAL CONSIDERATIONS: This item is approved as to form and legality, and requires majority vote for Board approval. -SRT RECOMMENDATION: To approve Change Order #6 for Contract 15-6437 Vanderbilt Beach Utility Conversion Services with MasTec, Inc., to increase the contract amount by $460,904.27 with a revised completion date of December 1, 2019 for the Vanderbilt Beach MSTU Utility Conversion Project Phase II and III.
