i Y - t INDIAN RIVER COUNTY, FLORIDA DEPARTMENT OF UTILITY SERVICES Date: September 29, 2015 To: Joseph A. Baird, County Administrator From: Vincent Burke, P.E., Director of utility Services Prepared By: Arjuna Weragoda, P.E., Capital Projects Manager Subject: Amendment No.1 to Work Order No. 12 with CDM Smith — Design, Permitting and Bidding Services for Construction of Well No. 7 and at the South County RO Plant DESCRIPTIONS AND CONDITIONS: On July 1, 2014 the Board of County Commissioners (BCC) approved CDM Smith to design, permit, and prepare technical specifications and include services during the bidding process of a potable water production well (Well No. 7). The proposed well was to be located at the northwest corner of the South County Park, adjacent to the ball fields. This location was agreed to by the Florida Department of Environmental Protection (FDEP) Central District and St. Johns River Water Management District (SJRWMD) in 2009. Since the 2009 efforts, the County has shifted from the Central District FDEP to the Southeast District of FDEP. This change resulted in a change in permitting staff and the previously proposed well location became a topic of concern for the Southeast District staff. FDEP requested that the well be relocated out of the dry stormwater treatment area and onto higher ground to allow for ease of access during compliance inspections during or after storm events. This change requires that the 100 percent design plans for both the well/wellhead and the pipeline be updated to reflect the new location, as well as to provide a modified electrical design. ANALYSIS: Previously, impact fee funds were used for the design services in anticipation of future growth demands in the southern portion of the county which never came to fruition. When the project was put on hold, the expenses incurred at that time were transferred to the operating fund. In an abundance of caution, the funding source now reflects the use of operating funds for the remaining engineering work and construction costs since well No.7 is being added for increased reliability and redundancy to the system, not for additional capacity. The Amendment No.1 to Work Order No.12 is to update the wellhead and pipeline plans to reflect the revised location of the well. Final plans will also include modifications to the electrical design to accommodate power being provided from a different location than previously considered. This task will include one discussion with FP&L to confirm the power feed assumptions. It is not anticipated that the specifications will require modification as a result of the relocation; however, the bid summary will be updated to reflect revised pipeline lengths as per the CDM Smith proposal dated September 28, 2015. Consultant will begin work immediately upon authorization of this a 163,
