Coating Inspection and Structural Deficiencies

In August of 2010, the roof of a large municipal water storage tank in suburban Chicago collapsed. The tank had performed without incident for more than 35 years. There were no early indications or warnings of roof problems prior to the roof failure. The tank coating had been inspected a number of times after the tank was initially constructed. This article discusses what happened, how the roof failure could have been prevented and lessons learned from this incident.
