Brown, County Administrator <br />Vincent Burke, P.E., Director of Utility Services <br />Arjuna Weragoda, P.E., Capital Projects Manager <br />Work Order No. 11 with Kimley-Horn and Associates for the Construction of Well <br />No. 4 at South County RO Plant (SCRO) <br />DESCRIPTIONS AND CONDITIONS: <br />Indian River County Department of Utility Services (IRCDUS) owns and operates six (6) Floridan supply wells, <br />which are the raw water supply and source water for the SCRO water treatment facility located on Oslo Road. <br />These wells are the lifeblood of the treatment facilities and maintaining efficient operation of these well fields <br />is critical to the sustainability of the water system. <br />On July 12, 2016, the Indian River County Board of County Commissioners (BCC) approved the bid award to All <br />Webbs Enterprises, Inc. for the rehabilitation of wells 3, 4, 5 and 6 to restore capacity and reliability of the raw <br />water supply wells to the water treatment plant, and to construct a new well No. 7. During the initial phases <br />of rehabilitation of well No. 4, it became apparent that the existing PVC casing was damaged significantly from <br />previous work to the extent of not being salvageable. The existing casing is cracked in several locations and is <br />potentially a sanitary hazard. Please refer to Attachment No. 2 (Well No. 4 Condition Report) for more details. <br />The Engineer's opinion of probable construction cost of a new well No. 4 based on All Webbs unit prices is <br />approximately $800,000.00. Once the consultant has prepared design documents and secured permits for <br />the new well No. 4, a detailed cost proposal will be requested by the existing contractor. In the best interest <br />of the county, it is recommended to request a change order from the contractor currently on-site in order to <br />defray mobilization costs, advertising/bidding cost and save time. Please note that a deduction of <br />approximately $100,000.00 for the rehabilitation of Well No. 4 will be credited as part of the Change Order. <br />ANALYSIS: <br />Staff requested that Kimley-Horn prepare a proposal for design, construction and testing phase services to <br />abandon existing well S-4 and to construct a new Floridan aquifer supply well No. 4 at the SCRO Water <br />Treatment plant. The scope is more specifically described in the attached Work Order No. 11. On November <br />4th, 2014, the BCC approved the Extension and Amendment of the Continuing Contract Agreement for <br />Professional Services with Kimley-Horn and Associates. The total negotiated cost for the Floridan Well No. 4 <br />Construction is outlined in work order No. 11 for a lump sum amount of $135,563.00, separated into four (4) <br />tasks. Therefore, payment will only be made for the work completed under the specific task. <br />FUNDING: <br />C:\Users\GRANIC"'1\AppData\Local\Temp\BCL Technologies\easyPDF 7\@BCL@10052622\@BCL@10052622.docx <br />P91 <br />
