Agenda 09/11/2018 Item #16C 909/11/2018 EXECUTIVE SUMMARY Recommendation to approve Change Order No. 5 for Contract 16-6638 with Mitchell & Stark Construction Co., Inc., to add 20 days and $481,571.05 to the Vanderbilt Drive Cul-de-sacs Public Utility Renewal Project (Project No. 70122), and to authorize the necessary budget amendments. OBJECTIVE: To provide reliable, sustainable, and regulatory compliant services to the customers along Vanderbilt Drive and the 14 adjacent Conners Subdivision neighborhood cul-de-sacs by replacing and refurbishing the water, wastewater and stormwater infrastructure in coordination with the Wastewater Basin 101 Program and the Vanderbilt Beach aerial to underground utility conversion. CONSIDERATIONS: On July 12, 2016 (as Agenda Item 11D), the Board approved Contract No. 16- 6638 to Mitchell & Stark Construction Co., Inc., for the Vanderbilt Drive Cul-de-sacs Project, which included the replacement of water, wastewater and stormwater infrastructure. On February 13, 2018 (as Agenda Item 11A), the Board approved Change Order No. 3, which added 290 days to the original contract, resulting in an August 22, 2019 completion date. Reasons for delay included: rephasing the project to coordinate with the Vanderbilt Beach MSTU Beautification Project; conflicts with existing water, stormwater, private utilities and MSTU infrastructure. There were unidentified additional fixed costs associated with the Change Order No. 3 time extension, which have since been identified and are included in Change Order No. 5. Hurricane Irma washed out the right-of-way and undermined the roadway along Vanderbilt Drive between 101st and 107th Avenues North. The project work could not proceed in the impaired areas (Phase 4) until the roadway, stormwater outfalls and surrounding areas were stabilized. To minimize further delay, Change Order No. 3 revised the work sequence allowing utility work to commence in Phases 6 and 7 instead of Phase 4. According to the project schedule at that time, if Vanderbilt Drive was not stabilized with a short-term solution by June 5, 2018, additional delay was anticipated thereafter until right-of-way stabilization was complete. On July 10, 2018 (as Agenda Item 16A18), the Board approved Request for Quotes No. 14 -6213 for construction of the Vanderbilt Drive Stormwater Outfalls Recovery project, which is scheduled to be complete in November 2018. Upon completion, this project will stabilize the right -of-way and allow the Vanderbilt Drive Cul-de-sacs Project to move forward in the remaining Phases 4 and 5. The contractor has accelerated work in Phases 6 and 7 resulting in an anticipated completion for those phases in January 2019. Due to this accelerated work, and the work done under the Stormwater Outfall Recovery project, the net impact to the schedule was limited to 20 additional days to complete the project. The total 310-day time extension (20 days from this Change Order and 290 days from Change Order No. 3 approved by the Board on February 13, 2018) increases the total project duration from 750 days to 1060 days and adds $481,571.05 in associated contract fixed costs (See Attachments 1, summary of expenses, and 2, Change Order No. 5). Of the additional $481,571.05 being requested, $450,501.95 are associated with the Change Order No. 3 time extension and $31,069.10 are associated with the Change Order No. 5 time extension. Fixed costs include: maintenance of traffic, rental of lots used for material staging, dumpster rentals, porta pots rental, geo-seismic services, asphalt paving additional labor associated with delay caused by Hurricane Irma. These services are required every working day from project start to final completion, regardless of duration. Staff will pursue FEMA and insurance reimbursement for any eligible expenses. 16.C.9 Packet Pg. 988 09/11/2018 FISCAL IMPACT: Funding is available in, and is consistent with, the FY2018 Capital Budget approved by the Board on September 21, 2017. The sources of funding are the Water Capital Fund (412) and the Wastewater Capital Fund (414).
