James E. Quarles WTP Reservoir Cleaning & Improvements Project

The Cobb County-Marietta Water Authority is soliciting bids for the James E. Quarles Water Treatment Plant (WTP) Reservoir Cleaning and Improvements Project, a comprehensive infrastructure rehabilitation initiative. The procurement targets qualified general, pipeline, and electrical contractors to execute a multi-faceted reservoir restoration project involving the removal and off-site disposal of approximately 30,000 cubic yards of accumulated sediment from a 6-acre reservoir. Key project deliverables include repairing the reservoir's clay blanket and slope protection, constructing a permanent access ramp and raw water bypass, and completing structural, electrical, bridge, and gate repairs or upgrades to inlet, outlet, and splitter box structures. A mandatory pre-bid conference is scheduled for December 13, 2024, with bids due on January 9, 2025. Bidders must submit a 5% bid bond alongside required affidavits and certifications, and the contract allows 450 days for substantial completion. The Owner reserves the right to reject all bids and potentially re-advertise the project.

The procurement appears open to all qualified contractors without specific set-aside designations for disadvantaged enterprises. While the advertisement does not specify incumbent vendors or existing technological infrastructure, the project suggests integration with current water treatment facilities. The bid documents will be electronically available through QuestCDN, facilitating broad access for potential bidders. Though a specific budget range is not explicitly stated, the complex nature of the project involving sediment removal, infrastructure repairs, and significant civil engineering work indicates a substantial investment. The successful contractor will be required to provide performance and payment bonds, and the contract will be awarded as a single comprehensive project. The scope of work suggests this is a significant municipal infrastructure improvement initiative with potential long-term implications for the Cobb County-Marietta water treatment system.
