On June 15, 2023, the Board of Commissioners authorized the Director of Procurement and Materials Management to award Contract 21-091-3P, Phosphorus Removal Modifications to Battery D, O’Brien Water Reclamation Plant (WRP), to IHC Construction Companies, LLC, in an amount not to exceed $14,850,000.00, plus a five (5) percent allowance for change orders in an amount of $742,500.00, for a total amount not to exceed $15,592,500.00.

To ensure adequate power for future needs in a relatively remote section of the O’Brien WRP, the contract requires certain revisions to increase the size of the 480V power distribution system, which will provide power to the new Return Activated Sludge Pumping Station. Since the contract work involves using all available spare power from the switchgear in the Process Control Building, it will be much more difficult to provide power from that location in the future. Therefore, the conduit and cables in the underground electrical ductbank being installed as part of this contract present an opportunity to cost-effectively accommodate future loads. The contractor submitted cost proposal (CO-8) for an extra in the amount of $711,378.06 and a credit in the amount of $383,823.61, for a net extra in the amount of $327,554.45, to upsize the conduit and cable for additional future electrical service. The engineer reviewed the proposal, found it to be reasonable, and stated via correspondence CO08, that the Engineering Department would recommend its approval.
This change order is in compliance with the Illinois Criminal Code since the change is due to circumstances not reasonably foreseeable at the time the contract was signed and is in the best interest of the District.
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 21-091-3P in an amount not to exceed $327,554.45 (2.20% of the current contract value), from an amount of $14,874,772.95, to an amount not to exceed $15,202,327.40.
Funds are available in Account 401-50000-645650.
Requested, Catherine A. O’Connor, Director of Engineering, GMR:NBP
Recommended, Darlene A. LoCascio, Director of Procurement and Materials Management
Respectfully Submitted, Marcelino Garcia, Chairman Committee on Procurement
