PROJECT UNDERSTANDING
The purpose of the project is to remove the aeration and Sunkist lift station MCCs and install new MCCs in their place at the City’s WRF#2 facility. The project includes removal of the MCCs, new concrete pads at the new MCC locations, prefabricated E-houses to enclose the equipment, awnings over the E-houses, new conduit and wiring, and associated work and appurtenances.
The project has a two hundred seventy (270) days duration from the Notice to Proceed.
The City requested a proposal for engineering support services for the project. The construction portion of the project will be bid in the next few months with the Notice to Proceed to follow.
Engineering support will be provided by the design engineer and will provide submittal review, RFI review, meeting attendance, and technical assistance during construction. Construction Management and Inspection will be part of a separate RFP.
The MCCs are furnished by the City and all other materials and equipment will be furnished by the Contractor. To ensure continuous plant operation during construction, multiple phases will be required to complete the work and transition the aerators and pumps from the existing MCCs to the new MCCs. Extensive coordination and scheduling will be required.
