Body
________________________________________________________________________________
Executive Summary
Castle Rock Water (CRW) staff requests Town Manager approval for a services agreement with Tetra Tech for assistance in creating the SCADA MP Phase VI Meadows and Remotes Sites System Design and Bid Phase Services project, for the not-to-exceed amount of $448,500, with a 10% Town managed contingency of $44,850, for a total authorization request of $493,350 (see Attachment A).
The table below shows the total approved expenditures to date on the SCADA MP by vendor:
The SCADA system is crucial to the security and efficient operation of CRW's water and wastewater facilities. In 2019, the SCADA Master Plan (MP) was completed to assess the system and develop a plan for its upgrade, maintenance, and operation. The Town Council approved the SCADA MP on December 17, 2019, which identified approximately $12 million in expenditures over seven years.
In late 2023, the SCADA MP implementation cost was reviewed and updated, revealing a 26% increase in equipment and implementation costs since 2019. Additionally, the update included newly identified work not previously covered in the 2019 scope. As a result, the revised estimated cost for full implementation of the plan over the next six years is approximately $24.9 million.
Budget Impact
Funds have been budgeted each year, through 2029, for the Master Plan Implementation. Funds for this project will be taken from the Water CIP SCADA System Improvements line items, by year, as follows:
