Summary & Background Request approval of a change order of less than 10% to modify the existing Scope of Work, to provide additional repairs and replacement of two (2) Fan Assemblies and 29 Fissure Cracks in the concrete wall of the water tank located in the Fulton County Government Center Complex.
Scope of Work: Request approval of Change Order No. 1 to provide additional repairs and replacement of two (2) Fan Assemblies and 29 Fissure Cracks in the concrete wall of the water tank located in the Fulton County Government Center Complex.
The two (2) Fan Assemblies are comprised of fans, motors, gearboxes, and couplings that were designed for 100,000 hours of operation if properly maintained but may be original to the building. Specific deficiencies include corroded fans having lost their protective exterior coating, gearboxes leaking oil and showing interior corrosion, failed or ill fitted omega couplings/ bushings, and non-functioning vibration and oil level switches. These conditions suggest a full replacement of all components of the Fan Assemblies are needed, rather than repair of the non-functioning ones.
Additionally, the investigation identified 29 fissure cracks in the concrete wall of the water tank requiring repair, more than the twelve (12) programmed in the Project scope. None of the cracks are structural in nature but without repair could lead to water leaks and wall deterioration. Repairing all 29 fissure cracks helps ensure the longevity of the Cooling Tower's structural integrity.
