Body
BACKGROUND & HISTORY:
The Motor Control Center (MCC) serves as the nerve center of Water Reclamation Facility No. 2 (WRF2), located at 650 East Harrison Street. It is responsible for managing and controlling the various motors, pumps and equipment critical to the facility’s wastewater treatment processes. Over time, the existing MCC has shown signs of aging, resulting in increased maintenance demands and operational inefficiencies. To address these challenges and ensure the continued efficiency and reliability of WRF2 while adhering to industry standards, the Utilities Department (UD) has undertaken the proactive measure of replacing the aging MCC at WRF 2, as well as the MCC at the Sunkist Lift Station.
The current MCC components have become obsolete, and sourcing replacement parts has become increasingly difficult due to their unavailability in the market. The new MCCs will provide better visibility into operational processes, enable timely decision-making, and improve the overall reliability of the facility. Upgrading the MCCs will lead to improved control, monitoring and maintenance of equipment which aids in optimizing wastewater treatment processes and preventing potential disruptions. This upgrade aligns with the department’s commitment to meeting the highest standards of wastewater treatment while ensuring minimal disruptions to daily operations.

Webb (the design and record engineer) prepared a comprehensive cost estimate for WRF No. 2 MCC Installation Sunkist and Aeration Electrical Upgrades Project in 2022. The engineer’s estimate of probable construction cost was $3,782,000 including contingency, design engineering and project administration.
Engineering support will be provided by Webb who will provide submittal review, Request For Information review, meeting attendance, and technical assistance during construction. Construction management and inspection service were solicited to City’s three on-call firms Webb, Dudek and Z and K. The City received only one proposal from Z and K to perform electrical inspection and project management in the amount of $130,400. Z and K’s existing on-call agreement will provide for those services to manage and oversee the day-to-day construction activities. City staff will serve as the overall Project Manager to uphold the contract documents while interacting directly with the Contractor, lead progress meetings, prepare and maintain project reports, oversee the schedule and budget, verify proper procedures and ensure that turnaround times for documents review and approval are followed. The Project Manager will also ensure the overall quality and delivery of the project. To ensure compliance with the plans and specifications, an inspector will be on-site as needed. The estimated cost of project management by City staff is approximately $20,000.
