91-06: On-Line Rebuild of Cooling Tower Serving a 500 MW Power StationUpgrading and rebuilding of cooling towers during plant outages is common practice in industry. Demolition and rebuilding of a tower while keeping the plant on line at full power presents special challenges and solutions. This paper describes such a rebuild program including the planning, specifying, and execution involved in replacing an existing wood framed tower with a concrete tower at the Grand River Dam Authority Power Station.
