Consent Item <br />Indian River County, Florida <br />Department of Utility Services <br />Board Memorandum <br />Date: August 4, 2022 <br />To: Jason E. Brown, County Administrator <br />From: Sean C. Lieske, Director of Utility Services <br />Prepared by: Harrison Youngblood, PE, Utilities Engineer, Utility Services <br />Subject: Change Order to TLC Diversified, Inc., for the South County Reverse Osmosis Water <br />Treatment Plant Membrane and Retrofit Project <br />Background/Analysis: <br />On June 15th, 2021, the Board of County Commissioners (BCC) awarded the bid to TLC Diversified (TLC) for <br />the South County Reverse Osmosis (SCRO) Water Treatment Plant (WTP) Membrane and Retrofit Project. <br />During the construction phase of this project, staff was made aware of deficiencies related to components <br />of the treatment plant that were not originally part of the project. The components that are deficient are <br />the switchgear and the raw water blend system. The County's Engineer of Record on the project, Kimley- <br />Horn and Associates (KHA), recommended replacement of the deficient components to ensure they are <br />updated along with the rest of the upgrades to the plant. <br />The SCRO WTP receives utility power from Florida Power and Light (FPL) for operation. Incoming power <br />enters through an existing 2,000 -Amp switchgear that is used to control, protect, and isolate electrical <br />equipment. The motorized breakers in the switchgear have exhibited failures, and replacement is <br />recommended by the County's Engineer of Record for the project. <br />The SCRO WTP utilizes raw water blend to stabilize their finished water quality. The piping has had leaks <br />before forcing Indian River County to weld "patches" in the piping to maintain operations. The blend filter <br />recently failed forcing operations to bypass the vessel altogether. These components are past their useful <br />life, and replacement has also been recommended by the County's Engineer of Record for the project. <br />Funding: <br />Funds in the amount of $483,463.83 for this project are derived from the Utilities/South WTP <br />Membrane/South R/0 Membranes & Retrofit account, number 471-169000-19503, in the Utilities <br />operating fund. Utilities operating funds are generated from water and sewer sales. Additionally, <br />$6,000,000 in American Rescue Plan (ARP) funding will be utilized to fund a portion of the overall <br />project. Those funds will be added as a reimbursement to the Utilities fund. <br />Description <br />I Account Number <br />Amount <br />Utilities/South WTP Membrane/South R/0 Membranes & Retrofit <br />1 471-169000-19503 <br />$483,563.83 <br />Page 1 of 2 <br />F:\Utilities\00_UTILITY - AGENDA TEMPLATE & GUIDELINES\2022 Agenda Items\081622 BCC Agenda Items\TLC Change Order SWTP <br />178 <br />
