Renovation of a water / sewer project in Lockbourne, Ohio. Conceptual plans call for the renovation of a water / sewer project.

The Department of Public Utilities (DPU), Division of Sewerage and Drainage (DOSD) have identified numerous Variable Frequency Drives (VFDs) and Harmonic filters at several Southerly Wastewater Treatment Plant (SWWTP) processes that are nearing the end of their useful service life and are becoming increasingly difficult to repair and maintain. This work for the SWWTP is part of the City's continuing effort to upgrade its treatment facilities, provide efficient, reliable, cost-effective operations, and enhance personnel safety. This contract will provide engineering services necessary for the preliminary design, detailed design, and engineering services during construction for the replacement and installation of new VFDs and Harmonic filters at the SWWTP. This project may be funded via the WPCLF program. The consultant shall provide recommendation on standardization of equipment that can be used in the DOSD Guide Specifications. The design of the VFDs and Harmonic filters may include the repurposing of existing VFD enclosures or Motor Control Center (MCC) buckets, or new enclosures, configuration and programming of VFDs, Programmable Logic Controllers (PLCs), and other new controls integrated into the existing controls systems, and any other work ancillary to providing a fully functioning system. The equipment specified will vary based on site conditions, building use, building permit requirements, and ease of maintenance issues. Consideration shall be given to increasing ease of maintenance, develop a standardization of operating systems, and specifying control systems access software. The VFDs and Harmonic filters shall conform to current regulatory, building codes, good engineering practice, City of Columbus guidelines, and be designed sufficiently for current or changing process needs. MBE/WBE Contract-specific subcontract goals are required for this contract. In order to receive credit for the participation of a MBE/WBE subcontractor, the consultant must use MBE/WBEs certified by the City of Columbus Office of Diversity and Inclusion at the time of bid. Note: a certified MBE or WBE awarded a contract as a prime consultant may count 100% of the dollar value of the work it intends to perform with its own forces toward the applicable contract participation goal. The MBE/WBE contract specific goal is: 10% The method of contractor selection has not been determined at this time
