These towers, which were 13 years old, were extremely deteriorated due to the fact that they were constructed of fiberglass. Over the past several years the towers had weakened; therefore causing the structures to implode. This, in turn, created problems with the movement of the cooling tower blades. A Professional Engineer was secured by the City to provide plans and specifications for the Replacement of all 4 Cooling Towers. The specifications prepared for the new towers required stainless steel, this will avoid the problems that had been prevalent with the exiting fiberglass towers. This is the first change order for this project for services that were not included in the original specifications. The work encompasses unforeseen conditions for additional repairs to valves, pumps, motors, etc., repairs that must be provided to allow maximum working efficiency of the Cooling Towers.
