Description
The City of Cincinnati is soliciting bids to replace the existing 4‑inch glass‑lined grit discharge pipe system at the Mill Creek Waste‑Water‑Treatment Plant. The contractor must remove approximately 700 ft of existing pipe, install new glass‑lined pipe, provide Victaulic couplings, hangers, supports, and perform pressure/leak testing, all while adhering to strict sequencing and shutdown constraints for the grit tanks. The scope includes providing all labor, equipment, and materials not supplied by the City, managing waste disposal, and complying with safety and environmental requirements.
• Remove and replace ~700 ft of 4‑in. glass‑lined grit discharge pipe.
• Supply and install 141 Victaulic couplings, 70 pipe hangers/supports, and an allowance for additional fittings (~$20 K).
• Conduct 75 psi leak testing, manage tank shutdowns (one at a time) with a 21‑day turnaround per tank, and provide all required equipment (e.g., man‑lifts, 1.5‑ton jib crane).
• Meet revised schedule: Substantial completion within 90 days of commencement and final completion within 30 days thereafter.
