ELGIN,ILLINOIS PROJECT 3491-23;4754-23 CHANGE ORDER No. 1 CONTRACT: Elgin, IL Baffle Wall Replacement Bid No.23-046 SCOPE: The original Project Scope for the 1MG Riverside Steel GSR was to blast and paint the entire roof structure and panels in preparation for replacement of all the baffle walls and associated support and fastening components. This Change Order is for all activities associated with the additional work of replacing the entire deteriorated rafter support structure. This Change Order also provides for the blasting and painting of the remainder of the reservoir interior (shell and floor) to provide complete replacement of the interior wet coating system. REASONS FOR CHANGE: Upon starting the Project on the scheduled date of October 16, 2023, the Contractor expressed concern regarding some observed roof rafters that were corroded to the extent they had partially broken free from their attachment points. After scaffolding had been erected, KLM performed a closer inspection of the roof structure and concluded many rafters were either corroded beyond repair or of questionable integrity. The conditions of the rafter structure were not foreseeable at the time the Project Specifications were developed due to the emergency nature of the baffle wall replacement and the inability to take the reservoir out of service. Given the extent of the degradation, the recommendation by KLM is to replace the entire roof rafter system with new steel of matching size and quantity. With removal and replacement of the entire roof support structure, it is anticipated that significant damage will be done to the existing coatings within the reservoir. Replacement of the entire interior roof and roof structure coatings is already part of the original Project Scope; however, replacement of the shell and floor coatings is not. By replacing the shell and floor coatings, the reservoir interior will have a uniform coating system that will ideally provide 15 to 20 years of service without needing significant repairs or disturbance to the new baffle walls. The result would be complete replacement of all interior wet coatings. The circumstances said to necessitate the change in performance were not reasonably foreseeable at the time the contract was signed; the change is germane to the original contract as signed; and the change order is in the best interests of the City of Elgin and is authorized by law.
