Consent Agenda Item ?m <br />Indian River County, Florida <br />Department of Utility Services <br />Board Memorandum <br />Date: May 28, 2019 <br />To: Jason E. Brown, County Administrator <br />From: Vincent Burke, PE, Director of Utility Services <br />Prepared By: Arjuna Weragoda, PE, Capital Projects Manager <br />Subject: Reclaimed Waterline Corrosion Evaluation — Bowman Work Order No. 2 <br />Descriptions and Conditions: <br />Indian River County Department of Utility Services (IRCDUS) has historically provided reclaimed water <br />(a.k.a. reuse) to area golf courses for irrigation. The distribution of reclaimed water between wastewater <br />treatment facilities, storage tanks, and other delivery points are transmitted via transmission and <br />distribution mains. These mains vary in size from 4 to 20 -inches and are comprised of Ductile Iron (DIP), <br />Poly Vinyl Chloride (PVC), and High -Density Polyethylene (HDPE). <br />Analysis: <br />Last fall, IRCDUS staff noticed external corrosion in a section of a 20 -inch reclaimed water DIP located on <br />the north side of 17th Street SW. Staff reached out to Bowman Consulting Group (Bowman) to perform a <br />corrosion evaluation analysis of the subject reclaimed waterline. As part of that request, Bowman <br />determined the need for an extensive evaluation of the reclaimed waterline to determine the cause of <br />corrosion. <br />The work order has been provided in accordance with the Continuing Contract Agreement for Professional <br />Engineering Services with Bowman dated April 17, 2018. The scope is more specifically described in the <br />attached Work Order No. 2. The total negotiated cost for Work Order No. 2 is a total sum amount of <br />$84,865.00. Substantial completion of this evaluation is estimated to take approximately four (4) weeks <br />from notice to proceed. <br />Funding: <br />Funding for the Reclaimed Waterline Corrosion Evaluation is available within the Utilities Other <br />Professional Services account in the Operating Fund. Operating fund revenues are generated from water <br />and sewer revenues. <br />Description <br />Account Number <br />Amount <br />Other Professional Services <br />471-23536-033190 <br />$84,865 <br />117 <br />C:\Users\legistar\AppData\Local\Temp\BCL Technologies\easyPDF 8\@BCL@C80D9952\@BCL@C80D9952.docx <br />
