Agenda Number: 22 Section Name: {{section.name}} Account Number: 72-4671 File ID: {{item.tracking_number}} TO: City Council
FROM: Alex Khojikian, City Manager
PREPARED BY: Public Works Department
MEETING DATE: June 16 th, 2025
SUBJECT:
Integrated Supervisory Control and Data Acquisition System Maintenance and Improvement – Contract Change Order RECOMMENDATION:
Approve Contract Change Order No. 4 to an agreement with Enterprise Automation for upgrading and maintaining the City’s Supervisory Control and Data Acquisition system in an amount not to exceed $125,000, for a revised total contract amount of $475,679; establish a contingency reserve of $20,000; and authorize the Public Works Director to execute the change order in substantially the form presented and execute change orders within the contingency reserve.
BACKGROUND:
The Supervisory Control and Data Acquisition (SCADA) system allows staff to remotely monitor and control equipment at the Wastewater Treatment Plant (WWTP) and sanitary sewer and stormwater pump stations throughout the City’s collection systems. Previously, the WWTP and pump station SCADA systems were standalone but have recently been integrated and updated as part of the Clean Water Program. As a critical system for monitoring operations and receiving alarms, the SCADA system requires ongoing maintenance to ensure proper operation.
In 2017-2019, the Clean Water Program issued a Request for Qualifications to preselect system integrators to perform SCADA and Programmable Logic Controller programming. Enterprise Automation (EA) was one of three preselected system integrators. Pre-authorization familiarizes the vendor with City design standards to allow them to program in the SCADA environment without causing unintended problems or catastrophic system errors.
In October 2023, a $40,804 agreement through June 30, 2024, was executed with EA for the review and improvement of the Marina Lagoon Pump Station, including alarm programming updates to improve the assets after the prior significant rain events. In November 2023, Council approved Contract Change Order No. 1 to increase EA’s scope and fee by $158,352, along with a contingency reserve of $30,000, to evaluate and implement additional functionality improvements to the SCADA system. EA is currently implementing those improvements. Last year, EA created a replica of the City’s SCADA system that is housed on their server system. Having this replica allows for testing of updates and changes in a safe environment prior to deployment thus insulating the City’s SCADA system from unknown or unintended consequences.
Contract Change Order No. 2 extends the term of the Agreement to July 31, 2024. In July 2024, Council approved Contract Change Order No. 3 to increase EA’s scope and fee by $151,523 and extend the contract to continue providing WWTP SCADA system maintenance support for the Fiscal Year 2024-25.
As a critical system for monitoring operations and receiving alarms, the SCADA system requires ongoing maintenance to ensure proper operation. EA is able to continue addressing both the required maintenance and system improvements needed for the integrated SCADA system. Staff recommends approval of Contract Change Order No. 4 to increase the budget by $125,000 and extend EA’s contract to maintain and improve the integrated SCADA system through Fiscal Year
