Title
Resolution Approving the Supervisory Control and Data Acquisition (SCADA) Master Plan Phase IV Implementation Project [Entire Castle Rock Water Service Area]
Town Council Agenda Date: September 3, 2024
Body
___________________________________________________________________________
Executive Summary
Castle Rock Water (CRW) seeks Town Council approval of a Resolution (Attachment A) approving a services agreement with Logical Systems, LLC (LSI), for the CRW Supervisory Control and Data Acquisition (SCADA) SCADA Master Plan Phase IV Project. This capital improvement was identified through the SCADA Master Plan (MP), adopted in December 2019 by Council Resolution No. 2019-131. The cost for this work is $4,475,720 plus a 10% Town managed contingency of $447,572, for a total authorization request of $4,923,292.
Through a competitive request for proposal (RFP) process, bids were received on July 18, 2024, and LSI was selected by CRW staff as the recommended consultant to complete these proposed system upgrades. The existing system is antiquated and has components that have been in service for up to 30 years. The scope of work for this project shall include, but not be limited to, the replacement of hardware, wiring, and software for SCADA control systems at the Miller Water Treatment Plant (WTP), and various wells and other remote sites. This project will bring the system into compliance with modern cybersecurity and equipment standards and improve operator efficiencies, as recommended by our 2019 SCADA Master Plan.
Once awarded, it will take approximately 19 months to fully implement. The timing fits into CRW’s operations by allowing the majority of the work to be completed during the low-demand seasons and the goal is to complete this by April 2026.
Notification and Outreach Efforts
This project is security-sensitive and no public outreach is planned. Work will be performed at remote CRW sites and will be done out of the public eye.
History of Past Town Council, Boards & Commissions, or Other Discussions
Castle Rock Water Commission was provided with a presentation on the SCADA Master Plan on December 11, 2019, and voted to recommend Council approval. Town Council adopted the 2019 SCADA Master Plan Update on December 17, 2019.
Discussion
In May of 2024, Burns & McDonnell Engineering, Inc. (BMcD) created the RFP for the SCADA Master Plan Phase IV, to create a complete and more consistent RFP, resulting in better contractor pricing, improved schedules, and a smoother overall project. This project was necessary to properly detail the required elements of the RFP and meet budget and schedule goals. The RFP contained the proper steps, equipment, software, and programming protocols necessary to ensure accurate estimates and proper project implementation details.
CRW uses SCADA to monitor and control all processes in the water treatment plants and their remote sites. This current project will upgrade hardware and software in the Miller WTP and associated remote sites listed below:
Phase IV Remote Facility List:
• Citadel Pump Station
• Hillside Pump Station
• Plum Creek Pump Station
• Castlewood 1 Lift Station
• Castlewood 2 Lift Station
• Maher Lift Station
• Mitchell Creek Lift Station
• Sellers Lift Station
• Black Feather PRV
• Briscoe PRV
• Scott PRV
• Valley PRV
• BM1A_D Well
• W7 Well
• RT6ABC Well
• RT14 Well
• BM2 Well
• Red Hawk Pond
• Meadows Flume
• North Flume
• Main Flume
• Meadows Grinder
The SCADA system is separate and segregated from other Town computer networks and is a stand-alone process by which many CRW assets are controlled remotely. This project will replace the hardware and wiring for the existing control system at these sites. The contractor will also be required to test all of the installed hardware, instrumentation, and wiring. Due to supply chain issues CRW has purchased and will be providing additional hardware, such as Programmable Logic Controllers (PLCs), power supplies, input and output (I/O) cards, racks, human-machine interfaces (HMIs) and network switches, for the contractor to install.
A more robust operational system will address deficiencies within the existing system and bring the system into compliance with modern cybersecurity and equipment safety standards. It also will reduce network failure risk due to aging equipment, reduce costs of support by utilizing current, non-obsolete hardware and software, improve operator efficiency by standardizing equipment and procedures, and properly manage risk and resilience associated with process automation.
In June of 2024, CRW advertised a request for qualifications (RFQ) for contractors using BidNet (an online platform that advertises information such as government RFQs). Six firms responded by submitting Statements of Qualifications. The contractor submittals were reviewed by the CRW staff and four contractors were shortlisted. The RFP was then issued to the shortlisted group of contractors and a mandatory project site visit was completed by staff with contractors and BMcD. The following table includes the contractors who issued the RFP for this project and their proposal cost or if they were non-responsive.

LSI was selected based on the qualifications that were submitted, the completeness of fulfilling the scope of work, and the project costs that were submitted.
LSI will be required to perform testing on all installed hardware and wiring, to ensure that all locations can communicate and operate properly. The contractor will also need to research, prepare, and submit to the appropriate agency any necessary permits for project completion. All work will be completed within an approximate 19-month period beginning in October 2024 and concluding in April 2026.
