�I <br /> II <br /> I <br /> Consent <br /> Agenda I� <br /> INDIAN RIVER COUNTY, FLORIDA <br /> DEPARTMENT OF UTILITY SERVICES <br /> Date: July 2, 2015 <br /> To: Joseph A. Baird, County Administrator <br /> From: Vincent Burke, P.E., Director of Utility Services <br /> Prepared By: Arjuna Weragoda, P.E., Capital Projects Manager �w <br /> Subject: Waive the Bid-Process for <br /> North RO Panel Replacement <br /> DESCRIPTIONS AND CONDITIONS: <br /> On May 19, 2015, the Indian River County Board of County Commissioners (BCC) approved Work <br /> Order No. 4 with Kimley-Horn and Associates, Inc. (KHA) to provide professional services for <br /> assessment, remediation, implementation bidding, and construction phase services for upgrades to <br /> the SCADA system at the South County Reverse Osmosis (SCRO) and North County Reverse Osmosis <br /> (NCRO) Water Treatment plants. <br /> i <br /> i <br /> Indian River County Department of Utility Services (IRCDUS) owns and operates two (2) regional <br /> potable water treatment facilities.The southern portion of Indian River County is served by the SCRO <br /> Water Treatment Plant which is rated for 8.57 million gallons per day (mgd). The NCRO Water <br /> Treatment Plant is rated for 11.44 mgd. <br /> Both water treatment plants are controlled and monitored by programmable logic controllers (PLC) <br /> and computer interfaces(HMI—Human Machine Interface)which make up the Supervisory Computer <br /> and Data Acquisition (SCADA) system. The SCADA system is crucial to the operation of the water <br /> system and the remote storage and pumping facilities. The current PLC systems at NCRO and SCRO <br /> plants are a mixture of various platforms of Allen-Bradley hardware: PLC5, MicroLogix(MLX),SLC and <br /> the newest ControlLogix (CLX). <br /> The assessment evaluation found the existing PLC5 hardware which comprises the majority of the <br /> hardware at both water plants to be antiquated. In addition to the corrosion in the panels, hardware <br /> replacements would be difficult and costly to acquire because the manufacturing and support of the <br /> PLC5 hardware has been discontinued by the vendor (Allen-Bradley). The evaluation confirmed what <br /> the Utility plant operators have voiced all along in that the existing system is slow to respond to <br /> commands, has poor communication, and does not allow any scalability for future growth or any <br /> changes to plant controls. The hardware is in dire need of replacement before it fails and is <br /> inoperable. <br /> 68 <br />
