Description

The City of Cincinnati is seeking proposals for the design of a Biologically Aerated Filtration (BAF) system to be retrofitted into the existing secondary treatment building at the Little Miami Wastewater Treatment Plant. The selected Offeror will work with the City to finalize an agreement for the design and furnishing of the BAF system, and support its installation and commissioning. The scope of work includes designing a new BAF system, coordinating with the EPS Project Team, and providing a fixed price assignable option for the purchase of equipment and construction phase services. • The BAF system must meet performance requirements and conceptual design criteria. • The system will be installed in the existing secondary treatment building. • The Offeror must demonstrate experience with similar BAF system installations. • The proposal must include a detailed description of the proposed BAF system, ability to meet performance requirements, schedule, and cost proposal.
