This amendment is required to address the malfunction of the odor control humidifier sump level sensors and transmitters in the Sludge Bio-Filter Building , Southwest Coarse Screen Bio-Filter Building and Post-Centrifuge Bio-Filter Building. The level sensors were improperly subjected to a high-pressure water misted environment where two of the three instruments malfunctioned from water intrusion; therefore, new level instruments are required to reduce the risk of future water damage. The contractor submitted a cost proposal (CO-35) for an extra in the amount of $25,085.50. The engineer reviewed the proposal, found it to be reasonable, and stated via correspondence CO35, that the Engineering Department would recommend its approval.
This change order is in compliance with the Illinois Criminal Code since the change is germane to the contract.
It is hereby recommended that the Board of Commissioners authorize the Director of Procurement and Materials Management to execute a change order to increase Contract 17-134-3MR in an amount of $25,085.50 (0.14% of the current contract value), from an amount of $17,308,972.22, to an amount not to exceed $17,334,057.72.
