Resolution Approving the Second Amendment to the Tank 17A and 17B Monoclor Residual Control System Station Construction and Installation [2362 Coachline Road Castle Rock, CO]
Town Council Agenda Date: August 20, 2024
________________________________________________________________________________
Executive Summary
Castle Rock Water (CRW) staff requests Honorable Mayor and Members of Town Council approval of a Resolution approving a Second Amendatory Agreement with Velocity Plant Services, LLC (see Attachment A) to provide additional materials, equipment and services for the Tanks 17A and 17B Chloramination Booster Station in the amount of $56,465.00, for a total authorization amount of $274,570.00. Town Manager approved an Equipment and Services Acquisition Agreement for Velocity Plant Services, LLC to construct a foundation and building with heating/cooling equipment, electric service, lighting, and SCADA peripherals and to install PSI Water Technologies, Inc purchased equipment for housing the Monoclor Residual Control System equipment on March 13, 2023 for $199,750.00 with a 10% contingency for a total authorization amount of $219,725.00. On October 17, 2023, Town Manager approved a First Amendatory Agreement for Velocity Plant Services, LLC to increase the size of the foundation and building based on the requirement of Colorado Department of Public Health and Environment (CDPHE) that for safety, two rooms within the building would be required for chemical storage since two chemicals would be potentially added to Tanks 17A and 17B. The added cost for these modifications was $18,355.00 for a total authorized amount of $218,105.00 for the First Amendatory Agreement. This Second Amendatory Agreement is for an added cost of $56,465.00 for inflationary and additional electrical feeder materials and labor, internal chemical spill containment, road gravel and placement, extreme cold weather heat booster equipment, and contractor supervision for a total authorization amount of $274,570.00.
Discussion
CDPHE requirements have grown for the project since the inception of the project from the Summer of 2022. To complete the project, a phased in approach will be required to gather continuous data on the existing tanks chloramines residuals prior to adding any chemicals. Discussions with CDPHE have yielded an agreement that no CDPHE permit is required to construct the building just to operate the water quality stations and mixers for gathering continuous water quality data. Economically, the building to house the PSI Water Technologies equipment and chemical addition equipment needed to be constructed upfront and comply with Town of Castle Rock Electrical and Building Codes. The growing CDPHE and code requirements have added costs to Velocity Plant Services, LLC original proposal.
Notification and Outreach Efforts
A Pre-App notification was issued by Development Services for the project in 2023.
Budget Impact
A balance transfer is required. $59,204.59 will be transferred from 210-4275-442.75-89 to 210-4275-442.75-38 to cover the current account overage as well as the Velocity Plant Services, LLC authorization.
