EXHIBIT A <br />WORK ORDER] <br />Indian River County Department of Utility Services <br />South Oslo Rd Water Plant <br />Well S-7 and S4 Control System Implementation <br />PROJECT UNDERSTANDING <br />Indian River County Utilities (IRCU) awarded construction of the South Oslo Rd <br />water plant well S-7 and the replacement of well S-4 to All Webbs Enterprises, Inc. <br />on July 12, 2016. Currently, completion of well S7 is scheduled for end of October <br />2017. Each of the new well designs include variable frequency drives (VFD) and <br />fiber optic (FO) communication which is an improvement and more robust and <br />reliable system over the existing radio telemetry (RTU) systems currently in place at <br />all of the existing wells. With VFD's, flow can be varied and controlled via the <br />water plant which is currently not available with the existing wells. With the FO <br />design, additional programming is necessary at both the water plant and wellsites <br />to provide direct communication with the water plant PLC. Integration of control <br />and monitoring of these wells with the other wells is the last element needed to <br />provide full operation of these two wells. Once complete, two of the seven wells <br />will have direct communication with plant and wells 7 and 4. <br />The following scope consists of modifying the existing plant PLC and HMI to allow <br />monitoring of flow, water level, and pump speed, and control of the pump <br />operation. Coordination and commissioning of the wellsite PLC and VFD <br />communication will also be provided. Consultant will utilize the services of <br />Control Systems Design, Inc. (CSD), to perform the programming and <br />commissioning, who has extensive knowledge of the IRCU water plant SCADA <br />systems. <br />SCOPE OF WORK <br />TASK 1- WELL S-7 AND S-4 PROGRAMMING <br />Consultant and CSD will review submittals of new control panel and modifications <br />to well 7, well 4, and the main PLC panel in the control room. <br />After finalization of the submittals from all vendors, Consultant and CSD will <br />create modifications for changes to the main processors to accept the additional RIO <br />K:\WPB_Civil\044572039 - SCRO Well S-4 Replacement\Admin\Exhibit A Well S7 and S4 SCADA Programming 8.15.17.docxPage 1 <br />of 3 <br />P246 <br />
