The purpose of this contract is to construct a 48-inch diameter sewer and connection structure in order to provide relief to the Calumet Intercepting Sewer 18F ext. A, Calumet Intercepting Sewer 18F, Calumet Intercepting Sewer 18E, and the Palos Hills Pumping Station during wet weather by diverting flow to the 78-inch Calumet Intercepting Sewer 20R-2.
The contract documents included stop logs to divert flow during wet weather to Calumet Intercepting Sewer 20R-2. Installing the stop logs would require mobilization inside the intercepting sewer during live conditions. In order to allow for safer working conditions for the District’s Maintenance and Operation staff during flow diversions, this change order deletes the stop logs from the scope and includes procuring and installing a stainless-steel rising stem slide gate with associated gate connecting components and modifications to the proposed connecting structure, to eliminate the need for personnel to enter the structure. The proposed gate installation and subsequent ability to enable flow diversion will also allow the District future bypass capabilities to rehabilitate the Calumet 18E intercepting sewer. The contractor submitted a cost proposal (CO-07) for an extra in the amount of $224,039.71 and a credit in the amount of $1,909.48, for a net extra in the amount of $222,130.23. the engineer reviewed the proposal, found it reasonable, and stated via correspondence CO07, 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 21-262-3S in an amount of $222,130.23 (7.70 percent of the current contract value), from an amount of $2,886,183.87, to an amount not to exceed $3,108,314.10.
Funds are available in Account 401-50000-645600.

Respectfully Submitted, Marcelino Garcia, Chairman Committee on Procurement
