Indian River County, Florida <br />Department of Utility Services <br />Board Memorandum <br />Date: September 6, 2019 <br />To: Jason E. Brown, County Administrator <br />From: Vincent Burke, PE, Director of Utility Services <br />Prepared By: Elliese Shaughnessy, El, Utilities Design Engineer <br />Subject: Approval of Kimley-Horn Work Order No. 15, "Ixora Park Sewer System Rehabilitation" <br />Background/Analysis: <br />Ixora Park Subdivision contains approximately 9,710 linear feet of vitrified clay pipe (VCP) gravity sewer and <br />23 manholes dating from 1952. A lift station connects the system from the northwest corner of the property <br />into a force main along 15t Street Southwest. Indian River County Department of Utility Services (IRCDUS) <br />has discovered deficiencies in the VCP through sand buildup and weakening of the roadways. <br />Kimley-Horn and Associates, Inc. (KHA) surveyed the gravity system and determined areas to restore or <br />replace. They recommend 4,100 linear feet (LF) of pipe to be lined and 3,100 LF to be replaced. KHA has <br />been tasked with the following: <br />• TASK 1: Create a report of recommendations for 2,500 LF of gravity sewer that has recently <br />undergone closed-circuit television (CCTV) inspection. This will include a comprehensive Opinion of <br />Probable Cost (OPC) for all gravity sewer rehabilitation and replacement. <br />• TASK 2: Prepare design specifications for pipe lining and lateral rehabilitation for 4,100 LF of gravity <br />sewer. Separate sets of bid documents will be provided for pipe lining and for lateral rehabilitation. <br />• TASK 3: Develop construction plans and technical specifications for pipe replacement. This will <br />include 60%, 90%, and final drawings as well as an OPC. <br />The schedule and cost are summarized below: <br />Task 1 Phase 2 Sewer System Evaluation Survey (SSES) 4 — 8 weeks $11,889 <br />Task 2 Pipe Lining and Lateral Rehabilitation 8 —10 weeks $15,889 <br />Task 3 Full Sewer Pipe Replacement 4 — 6 weeks $52,441 <br />Total $80,219 <br />Funding: <br />Funding for this project is derived from operating funds. Operating fund revenues are generated from water <br />and sewer sales. Funding for this project is programmed for fiscal year 2019/2020. Therefore, please note <br />that the notice to proceed will be issued October 1, 2019. <br />112 <br />
