Repair of 50-year Old Hyperbolic Cooling Tower


CTLGroup was retained by a regional power company to facilitate a structural repair program for 370-ft tall natural draught hyperbolic cooling tower.  The reinforced concrete cooling tower was constructed in 1964. Widespread concrete consolidation defects in original construction resulted in leakage and corrosion of the shell reinforcing steel over time.  CTLGroup’s scope of work included developing repair plans and specifications, assisting with the repair contractor selection process and providing repair construction support services. Construction support services included reviewing the contractor’s means and methods for safe access and systematic implementation of the required repairs. Support services also included evaluation of proposed repair materials, review of procedures used to execute various types of repairs and review of quality control documentation.
