The purpose of this contract is to construct a 48-inch diameter sewer and connection structure to provide relief to the Calumet Intercepting Sewer 18F, Calumet Intercepting Sewer 18F ext. A, 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 work to connect the proposed 48-inch diameter sewer to an existing access manhole. However, upon field investigation it was discovered that an existing concrete platform inside the access manhole was in direct conflict with the sewer connection. Change order COR-02, approved on October 27, 2023, included work for demolition of the concrete platform and sewer connection. However, reinforcement material and labor associated with the restoration work was omitted from the scope as the condition of the manhole wall was not ascertainable at the time. Change order COR-08 includes the installation of reinforcement and associated labor to restore the access manhole wall affected by the removal of the concrete platform as submitted in the approved shop drawings. The contractor submitted a cost proposal (CO-08) for an extra in the amount of $9,192.69 and a credit in the amount of $0.00, for a net extra in the amount of $9,192.69. The Engineer reviewed the proposal, found it to be reasonable, and stated via correspondence CO08, that the Engineering Department will recommend its approval to the Board of Commissioners.
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 $9,192.69 (0.30% of the current contract value), from an amount of $3,108,314.10, to an amount not to exceed $3,117,506.79.
Funds are available in Account 401-50000-645600.
Requested, Catherine A. O’Connor, Director of Engineering, KMF:LS
Recommended, Darlene A. LoCascio, Director of Procurement and Materials Management
Respectfully Submitted, Marcelino Garcia, Chairman Committee on Procurement
