Site work for a water / sewer project in Rawlins, Wyoming. Working plans call for site work for a water / sewer project.

The City’s Water Treatment Plant currently uses Programmable Logic Controllers (PLCs) technology to allow communication between the sensors and controls associated with the different assets of the Water Treatment Plant and the Supervisory Control and Data Acquisition (SCADA) system. The PLC components are requiring replacement and the hardware and software assets need a revamp to introduce improvements to the SCADA system, including operation and cybersecurity improvements. scope of work: 1. Develop a new schematic, plans and specifications for a water SCADA system that includes all necessary sensors and controls that fits the following requirements: a. Have PLCs that allow communication between the hardwire sensors and controls and the SCADA server, along with failover PLCs b. Have a modernized wireless capable input/output device(s) that will allow transmission of sensors and controls that are not feasible with PLC technology to the SCADA with a failover device c. Use Ignition by Inductive Automation for the viewing of sensor data and control different parts of the water system d. Have a hardwire auto dialer device that has alarms for 12 critical sensors e. Use modern technologies to control flow of data and controls to and from the SCADA f. Use the provided map of the different assets to determine best which sensors and controls should be on PLCs and which sensors and controls should be on the wireless input/output device(s) g. Control and read data from the Water Treatment Plant, Wastewater Treatment Plant, and the Pre-treatment plant. h. Read the following levels: i. Tank levels ii. Chlorine levels iii. Ph levels iv. Flows v. Turbidity i. Control the following controls: i. Tank levels ii. Chlorine levels iii. Flows iv. Pumps 2. Develop schematic, plans and specifications for connecting the SCADA software, Ignition by Inductive Automation, to all the sensors and controls based on the new schematic for the PLCs and wireless input/output device that collect and send data from and to SCADA 3. Develop SCADA software to meet the following requirements: a. Be able to grant control to various users with different kinds of permissions b. Have GIS capabilities for the different assets of the water system c. Have real-time water flow, tank levels, 4. Establish plan for connecting SCADA to software auto dialer that will send out alarms via SMS, calls, and emails 5. Develop user-friendly UI design for user interface for the SCADA that takes advantage of the Ignition Software by Inductive Automation. 6. Provide an estimated implementation timeframe i.e., project schedule for completion of the setup of the project. 7. Develop, and assemble a complete bid package for advertisement. a. Package will include plans, specifications, and an engineer’s estimate 8. Progress meetings will be expected, by phone or in person, on a weekly basis during the development and startup phases. 9. Proposals must be received no later than 2:00pm, Mountain Time, on April 13th, 2023. Proposals will be publicly opened at that time. Once opened, proposals will be filed for public inspection and become the property of the City. 10. Submittals and Document Finalization. Submit draft schematics, plans and specifications at the thirty percent (30%) and ninety percent (90%) design stages for City review.
