Executive Summary
Castle Rock Water (CRW) staff requests approval of a Services Agreement (Exhibit 1) with Burns & McDonnell Engineering (BMcD) to provide construction engineering services for the Ray Waterman Regional Water Treatment Center (RWRWTC) and Bell Mountain Ranch Water Treatment Plant (BMR) LAS Conversion Project.
Discussions
This contract will include scope to provide construction engineering services to support construction activities at the RWRWTC and BMR. The work at BMR includes installation of a new liquid ammonium sulfate (LAS) chemical feed system, resulting in the switch from free chlorine to chloramines as the disinfectant in the BMR system to align with the rest of the Town’s water distribution system. The work at RWRWTC will include conversion of the existing anhydrous ammonia chemical system to a liquid ammonium sulfate (LAS) chemical system to improve safety and align with chemicals being used at other facilities in the system. The location of the conversion from free chlorine to chloramines will be modified in the facility to improve operational flexibility and allow the Town to receive WISE flows even when RWRWTC is taken offline. The project also includes upgrades and replacement of instrumentation, control panels, and other work that was originally going to be completed as part of a different project (SCADA Phase V project). The SCADA work that is located inside, or is controlled from, the chemical building is now being included within this LAS Conversion project scope.
Burns & McDonnell (BMcD) completed design services for the LAS conversion work at the two facilities, as well as the SCADA upgrades work at RWRWTC. RWRWTC LAS Conversion and Wise Modifications design was completed in 2023, and the BMR LAS Conversion design was completed in 2025. CRW Staff requested a scope and fee from BMcD to complete the construction engineering services for this work. The engineering services shall include, but not be limited to, leading construction meetings, review and comments on equipment submittals and requests for information (RFIs), periodic site visits, review of change orders, preparation of change directives, start-up workshops and support, Colorado Department of Public Health and Environment (CDPHE) certifications, final completion inspection and punch list items follow up, and creation of conforming to construction record drawings. A scope of services and fee schedule were submitted by BMcD for these services and are included with Exhibit 1. Staff recommends approval of the agreement between the Town of Castle Rock (TCR) and BMcD for $270,997 for the RWRWTC and BMR LAS Conversion Project. Services are expected to begin upon execution of the contract and be completed by May 2026.
From a construction completion standpoint, the project will be completed in two work packages. The first construction work package has been approved and is being completed to allow for procurement of long lead equipment that is necessary for the project. Long lead equipment includes the chlorine analyzers, programmable logic controller (PLC) panel, variable frequency drives (VFDs) for chemical feed pumps, and chemical storage tanks. It is necessary to purchase this equipment as early as possible to complete the work in the necessary schedule. A second work package will be proposed to Town Council for approval after the overall project pricing is known. Garney Companies Inc. (Garney) has been selected via sole source to complete the project. Garney is under contract to complete scope included in Work Package 1 of the construction contract.
