CITY OF SANTA ANA EXHIBIT A <br />RFP NO.: 17-087 <br />WATER SYSTEM CONTROL DESIGN, PROGRAMMING AND SUPPORT SERVICES <br />SCOPE OF WORIK <br />Introduction and Background: <br />The City of Santa Ana is located in the heart of Orange County, California and is approximately 27 square <br />miles. The City provides potable drinking water for all of the City's residents and businesses. The City's water <br />production system consists of 22 wells, 4 pressure control stations, 7 Metropolitan Water District connections, 7 <br />water booster stations and 8 reservoirs. Control and monitoring of the water system is coordinated via the City <br />SCADA system using a series of radios to send and receive data from remote locations to the City Horne <br />SCADA control room. <br />Description of Work: <br />The City desires to retain qualified Consultants to provide control system design, engineering, integration, and <br />programming support on an as -requested basis for the City's water production facilities. The City's facilities <br />are controlled by the Dynac ES SCADA software as provided by Kapsch TrafficCom USA, Inc. <br />The City water production sites consist of facilities with many of the following components: Modicon <br />Momentum Programmable Logic Computers (PLC), ABB Variable Frequency Drives (VPD), Limitorque motor <br />operated valves (MOV), mag meters (various brands) and other related appurtenances. Local control is often <br />achieved via a human machine interface (HMI) local to the remote terminal unit (RTU) control panel. The <br />HMIs at any station are either the Magelis HMI or a Unitronics display. It is the City's desire that all site <br />control reside within the site PLC with the HMI acting primarily as a site control interface relaying operator <br />commands to the site PLC. <br />Consultant Responsibilities: <br />CONTROL SYSTEM DESIGNSERVICES <br />Consultant shall be required to provide full control panel designs which conform to City standards, for well, <br />pump motor and control valve operations. Control panel designs shall contain fully engineered diagrams that <br />specify all equipment, back panels, terminal blocks, special components and related items. Also included in the <br />design shall be all control wiring diagrams, specific 1/0, panel elevations, item and quantity lists with specific <br />part numbers. Control systems designs shall be complete and inclusive, of all information necessary for the City <br />to utilize as bid/procurement documents to have the panels built and installed, The Consultant shall provide <br />SCADA, control and instrumentation design support services, including but not limited to those described <br />below: <br />• Consultant shall perform field investigations of existing control panel wiring to verify and, as needed, <br />correct wiring drawings for existing control panels. Consultant shall make corrections to wiring <br />drawings as necessary to reflect current field conditions prior to performing any detailed design work. <br />• Consultant shall provide and/or prepare documentation, schematic drawings, and SCADA network <br />configuration diagrams for future use, maintenance, and programming of the SCADA system. The <br />detailed design documents may include the following: <br />o Hardware Engineering and Design Layout — Scaled drawings shall be prepared showing existing <br />Page 1 of 3 <br />
