In early 1992, the Escambia County Utilities Authority determined that its 2 mgd Avondale Wastewater Treatment Plant should be expanded to 8 mgd to meet the growing needs of the Pensacola, Fla., community. The design was completed and bids were taken in 1994. The new plant was to be operational by the end of 1997, but the bids were far greater than what was budgeted. Instead of redesigning the plant to meet the budget, the Authority developed an alternative method of delivering the project. The method included a separate bid for the treatment plant process and related equipment. Based on the design, lump sum design/build bids were taken for the balance of plant construction and equipment installation. The new facility includes a new influent pump station and screening, new tankage and biological nutrient removal capabilities, new final clarifiers and effluent filters, an ultraviolet disinfection facility, and an effluent pumping station. The alternative design/build project saved the city about $2 million and was completed in February 1998, only 2 months later than the original schedule.
