Cooling Tower Repairs

Climate-informed planning

Project Facts

Location Jacksonville, Florida
Owner Jacksonville Electric Authority


To address ongoing corrosion-induced deterioration in two 458-foot-tall cooling towers at the St. Johns River Park Plant, the Jacksonville Electric Authority retained our team to prepare a repair package. Considerations for hurricane season were factored into the plan, and approximately 200,000 square feet of deteriorated concrete was successfully replaced with durable concrete repair materials.

About the project

A wind load analysis considered the impact of concrete removal on the tower during the remediation. The analysis results were used to establish concrete removal limits and work-phasing scenarios to be followed during construction for hurricane and non-hurricane seasons. The restoration work included materials testing, extensive concrete repair of the cooling tower veils, and the installation of an impressed current cathodic protection system to both towers to mitigate corrosion in the reinforcing steel.
