Little Miami WWTP High-Rate Treatment Facility (Progressive Design-Build)

The City of Cincinnati seeks a qualified design‑builder to deliver a two‑phase, progressive design‑build for the Little Miami Wastewater Treatment Plant High‑Rate Treatment (HRT) Facility. Phase 1 involves completing all necessary engineering analyses and producing a complete design package for the HRT facility, associated disinfection systems, and pump‑station upgrades. Phase 2 consists of bidding services to develop a Guaranteed Maximum Price (GMP) and then managing construction, with the potential to self‑perform portions of the work. The procurement will first issue an RFQ to shortlist firms, followed by an RFP for the selected candidates. • Scope covers design, engineering, procurement, and construction management of a new HRT facility, disinfection equipment, and pump‑station upgrades. • Two‑phase approach: design (RFQ) → construction (RFP) with GMP development. • Potential for the contractor to self‑perform some construction tasks.
