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, 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. The scheduled contract completion date is September 8, 2026.
As of February 6, 2026, the attached list of change orders has been approved.

Current Contract Value $15,528,569.30

Item 1: Revisions to the steam supply for the unit heater (CUH-1) in the Return Activated Sludge Pump Station are necessary. The current design does not include provisions for controlling the steam supply, which would result in a continuous supply of steam to the heating coil of CUH-1 even when the thermostat does not require heating. The contractor submitted a cost proposal (CO-52) to provide labor, additional materials, and the equipment necessary to modify the steam supply to CUH-1 in the Return Activated Sludge Pump Station for an extra in the amount of $21,630.24 and a credit in the amount of $82.50, for a net extra in the amount of $21,547.74. The engineer reviewed the proposal, found it to be reasonable, and stated via correspondence CO52 that the Engineering Department would recommend its approval.
Item 2: Revisions to the lifting cable support frames for the fermenter and aeration tank mixers are necessary. The engineer found that the lifting cable support frames shown in the contract are no longer necessary. The mixer manufacturer, Xylem, recommended installing additional cable winches/spoolers instead. These cable winches/spoolers will be easier for maintenance staff to use and more effective at keeping the cables in tension when they are not in use. The contractor submitted a cost proposal (CO-53) to provide labor, materials, and equipment necessary to delete the lifting cable support frames and install additional cable winches/spoolers for an extra in the amount of $19,664.31, and a credit in the amount of $52,098.70, for a net credit in the amount of $32,434.39. The engineer reviewed the proposal, found it to be reasonable, and stated via correspondence CO53, that the Engineering Department would recommend its approval.
Item 3: Revisions to the Return Activated Sludge Pump Station driveway are necessary. These revisions will address the potential of pavement settling due to grade differences from the driveway edge to the adjacent roadway curb. The revisions will also reduce the slope of the driveway in the north-south direction to eliminate the possibility of the undercarriage of a vehicle making contact with the ground during equipment loading. The contractor submitted a cost proposal (CO-56) to provide labor, materials, and equipment necessary to revise the Return Activated Sludge Pump Station driveway for an extra in the amount of $48,113.12, and a credit in the amount of $0.00, for a net extra in the amount of $48,113.12. The engineer reviewed the proposal, found it to be reasonable, and stated via correspondence CO56, that the Engineering Department would recommend its approval.
These change orders are in compliance with the Illinois Criminal Code since the changes are germane to the contract.
It is hereby recommended that the Board of Commissioners authorize the Director of Procurement and Materials Management to execute these change orders to increase Contract 21-091-3P in an amount of $37,226.47 (0.24% of the current contract value), from an amount of $15,528,569.30, to an amount not to exceed $15,565,795.77.
Funds are available in Account 401-50000-645650.
