Brown, County Administrator <br />From: Vincent Burke, PE, Director of Utility Services <br />Prepared By: Terry Southard, Operations Manager <br />Subject: Work Order No. 14 with Kimley Horn for Bulk Acid Tank Replacement at North (Hobart) <br />County Water Plant <br />Descriptions and Conditions: <br />Indian River County Department of Utility Services (IRCDUS) operates the North (Hobart) County RO Water <br />Treatment Plant (WTP) located at 7757 58th Avenue, Vero Beach. <br />Hobart was built in 1998 and expanded in 2007. As part of the 2007 expansion, a 16,000- gallon sulfuric <br />acid tank was installed for daily water production. Typical service life for this type of a tank is 10-15 years. <br />Therefore, the Hobart tank is nearing its useful life and needs to be replaced. <br />Analysis: <br />In April 2019, staff requested Kimley Horn submit a proposal for professional engineering services to <br />review existing tank, piping and provide options for replacement of the tank. As part of the proposal, <br />Consultant will also review acid consumption and the potential for a reduction in usage and subsequent <br />storage capacity. <br />Per the Continuing Consulting Engineering Services Agreement for professional engineering services dated <br />April 17, 2018, Kimley-Horn submitted a proposal for design, bidding assistance and construction <br />management services. Kimley-Horn has submitted Work Order No. 14, which includes professional <br />services for review, design, bidding and construction phase assistance to replace the existing sulfuric acid <br />tank. The total negotiated cost for the professional services is a sum amount of $ 21,710.00. <br />The engineer's estimated construction cost for these improvements covered in the Scope of Work for <br />Work Order No. 14 is approximately $130,000.00. <br />Funding: <br />Funds for this project are derived from the renewal and replacement budget in the operating fund. <br />Operating funds are generated from water and sewer revenues. A request to roll forward the funds to <br />cover any construction not completed by September 30, 2019, will follow at fiscal yearend. <br />Description <br />Account Number <br />Amount <br />NWTF Acid Tank Replacement <br />47123536-044699-19560 <br />$151,710.00 <br />36 <br />
