INDIAN RIVER COUNTY, FLORIDA <br /> DEPARTMENT OF UTILITY SERVICES <br /> oRm <br /> Date: June 21, 2016 <br /> To: Jason E. Brown, County Administrator <br /> From: Vincent Burke, P.E., Director of Utility Service <br /> Prepared By: Arjuna Weragoda, P.E., Capital Projects Manager AO <br /> Subject: Work Order No. 1 with Carollo Engineers, Inc., for Manhole Rehabilitation at <br /> Ixora Park Subdivision. <br /> DESCRIPTIONS AND CONDITIONS: <br /> Indian River County Department of Utility Services (IRCDUS) owns and maintains approximately 82 <br /> miles of gravity sewer mains. Some of these mains are approximately sixty (60) years old and are in <br /> need of replacement or restoration. Staff elected to restore six (6) brick manholes within the Ixora <br /> Park Subdivision that were constructed in 1959. Staff initially budgeted the subject work to be done <br /> utilizing Glass-Fiber Reinforced Polyester (FRP) liner, which has been used in the past at lift stations. <br /> Once we evaluated the in-situ conditions, staff realized the FRP method of rehabilitating these <br /> manholes will cost twice the amount budgeted for the following reasons: <br /> • FRP lining system will require the removal of the cone. Given that the existing cone is brick, <br /> we may have to construct new cones. <br /> • Removing and replacing the cones will require road restoration. Given that the base has <br /> failed around the manholes, sub-grade and base work may have to be restored. <br /> • Extensive maintenance of traffic (MOT) will be required for this process, which may escalate <br /> the estimated cost. <br /> Therefore, for all the reasons stated.above, Engineering and Operations staff evaluated an epoxy <br /> coating system as an alternative to the installation of the FRP liner system. <br /> ANALYSIS: <br /> Staff requested that Carollo Engineers Inc., who has had experience with this coating system at <br /> various locations in Florida, prepare a proposal for Professional Services to assist the County in <br /> preparing the technical specifications for the subject application and limited quality control/training <br /> of Operations staff. The work order will be provided in accordance with the Extension and <br /> Amendment of the Continuing Services Contract Agreement for Professional Services with Carollo <br /> Engineers, Inc., dated November 4, 2014. The scope is more specifically described in the attached <br /> Work Order No. 1. The total negotiated cost for the engineering and application services to restore <br /> the brick manholes is a lump sum amount of$47,200.00, separated into three (3) tasks. <br /> 29 <br />
