Title
Resolution Approving a Services Agreement Between the Town of Castle Rock and Burns & McDonnell Engineering Company, Inc., for the MWTP Improvements & RWRWTC Chlorine Storage Project [Meadows Water Treatment Plant and Ray Waterman Regional Water Treatment Facility]
Body
________________________________________________________________________________
Executive Summary
The purpose of this memo is to request the Town Council approval of a Resolution (Attachment A) for the Design Services Agreement (Exhibit 1) with Burns & McDonnell for design engineering and bid support services for the design of the Meadows WTP Improvements and RWRWTC Chlorine Storage Project. Improvements at Meadows WTP include the replacement of underdrain systems within the gravity media filters, conversion from the existing anhydrous ammonia to liquid ammonium sulfate, and an evaluation of facility hydraulics to evaluate production capacity. Improvements at RWRWTC include expansion of chlorine storage to meet industry standards and ensure adequate supplies during peak demand season. Staff recommends approval of the agreement between Castle Rock Water (CRW) and Burns & McDonnell for $349,068 with a 20% town managed contingency for a total authorization of $418,882. Services are expected to begin upon execution of the contract and be completed in summer of 2027. Construction at Meadows WTP is currently planned for the 2027/2028 low demand season. Construction at RWRWTC is not budgeted until 2032, but temporary/phased implementation may allow for a sooner schedule.
Budget Impact
The Burns & McDonnell proposal fee is $349,068. Staff requests an additional $69,814 (Town-managed 20% contingency) be authorized for a total project authorization of $418,882. The project will be funded from the Miller WTP Piping & Filter Fund (210-4275-442.75-44). A contingency greater than 10% is being requested on this project because this project includes multiple types of projects at multiple facilities. The CRW team is investigating operations and chemical injections at MWTP currently, so it’s possible that some additional design scope may be identified from those investigations. Additionally, CRW wants to encourage BMcD to be creative with new ideas for phasing the chlorine storage capabilities at RWRWTC.
