Dear Sir:
On January 24, 2019, the Board of Commissioners authorized the Director of Procurement and Materials Management to award Contract 11-186-3F Addison Creek Reservoir, Bellwood, Illinois, to IHC Construction Companies in an amount not to exceed $63,280,000.00, plus a five (5) percent allowance for change orders in an amount of $3,164,000.00, for a total amount not to exceed $66,444,000.00. The scheduled contract completion date is August 18, 2022.
As of April 16, 2021, the attached list of change orders has been approved. The effect of these change orders resulted in an increase in an amount of $27,045,979.60 from the original amount awarded of $63,280,000.00. The current contract value is $90,325,979.60. The prior approved change orders reflect a 42.74 percent increase to the original contract value.
Item 1: During the construction of the channel improvements for the reservoir, the contractor notified the District that the existing condition cross-section drawings did not match existing condition in the field. The District design engineers determined that additional riprap, grouted riprap, soil, and clay cap were needed to complete the channel improvements. The contractor also notified the District that soil on Indiana Harbor Belt Railroad’s property and on Memorial Park District’s property was contaminated, non-special waste soil (NSW) versus clean construction or demolition debris (CCDD) material, and the contaminated, NSW material would require disposal in a landfill. The District requested the contractor to submit a cost proposal for these proposed changes. The contractor submitted a cost proposal (CO-12) for an extra in the amount of $263,089.85 and a credit in the amount of $62,515.71, for a net extra in the amount of $200,574.14.The Engineer reviewed the proposal, found it reasonable, and stated via correspondence CO12, that the Engineering Department would recommend its approval.
Item 2: The District design engineers determined that the backup floats for the pump station wet wells were not going to work as originally designed. The District requested that the contractor provide a cost proposal to install backup transducers in lieu of backup floats. The contractor submitted a cost proposal (CO-13) for an extra in an amount of $1,466.30 and a credit in amount of $0.00, for a net extra in amount of $1,466.30. The Engineer reviewed the proposal, found it reasonable, and stated via correspondence CO13, that the Engineering Department would recommend its approval.
The above two change orders are in compliance with the Illinois Criminal Code since the changes are due to circumstances not reasonably foreseeable at the time the contract was signed and are 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 two change orders to increase Contract 11-186-3F in an amount of $202,040.44 (0.22 percent of the current contract value), from an amount of $90,325,979.60, to an amount not to exceed $90,528,020.04.
