CITY OF SANTA ANA REP NO.: 21-127 SA-2 PRESSURE CONTROL STATION RELOCATION AND TRANSMISSION MAIN IMPROVEMENTS B. The Consultant will be required to create dashboard concept designs and standards. This will include elements that should be provided on an HMI dashboard. The intent is to provide information to benefit operations and provide operator controls as dictated by the City. C. The Consultant will be required to create, establish and/or maintain PLC programming standards as it relates to operation of the station. Under this duty, the Consultant shall develop application programming templates, subroutines, function blocks and data structures to minimize the level of custom programming required to operable assets to any sites such as pump stations. Standardized templates and modules shall serve as starting points for future programming efforts. D. The Consultant shall provide an estimate and list for all hardware necessary and proceed, upon City approval, to purchase said hardware, install as necessary and reprogram. E. The Consultant shall modify the functional specifications for the site and include the following: a. Narrative overview of the function and operation of the Site; b. Identification of all components of the Site (i.e., equipment, instrumentation, etc.); c. Narrative description of the functionality of each component of the Site (e.g., tanks, valves, meters, sensors/transmitters, etc.); d. Description of the process control strategy for the Site; e. Narrative description of all operational modes for the Site; f. Narrative description of each process control strategy; g. Identification of the specific 1/0, setpoints, commands and communications associated with each strategy; h. Detailed description of the control logic for each component/strategy, including permissives, interlocks, PID controls, etc.; i. Description of the SCADA interfaces; j. Narrative and detailed description of the system alarms and other notification functionality. F. The Consultant shall develop comprehensive Factory Acceptance Test (FAT) and Site Acceptance Test (SAT) protocols and criteria for the new control panels and related components. 5. Make recommendations for communications between SA-2 and Walnut Pump Station. Propose alternatives for communications in addition to radio communications. Identify all requirements for the options including maintenance and operation related constraints. The City uses an MDS iNET-II radio network for SCADA communications. In the near future, the City may alter the telecommunications scheme. In the event that another radio telemetry network is established, the Consultant shall assist with that work as it pertains to this project. The City may request design assistance for a new radio network and technology options, if deemed in the best interests of the City. Fiber interconnects remain an option. Page 6 of 11
