Progressive Design-Build Services for South Cobb Water Reclamation Facility Expansion

Cobb County Water System seeks a Design-Builder to provide professional, construction, and commissioning services for the expansion of the South Cobb Water Reclamation Facility from 40 Million Gallons per Day (MGD) to 50 MGD Maximum Month Flow. The County issues this pre-solicitation notice only, and proposers do not need to take action at this time. The County estimates releasing the Request for Proposals on January 8, 2027, with electronic responses due via its eProcurement system on February 25, 2027. The County will evaluate technical qualifications and cost proposals concurrently using a single-step, best-value selection process to choose the most favorable combination of qualifications and pricing. The County estimates the project budget at $300M to $400M, though the final Guaranteed Maximum Price will depend on Phase One design and value engineering. Proposers and key firms must hold appropriate Georgia licenses, and the Design-Builder must have the capacity to obtain 100% Performance and Payment bonds.
