The scope of Contract 11-404-3S includes lining of 10,900 feet of Upper Des Plaines Intercepting Sewer 11D, Extension C, rehabilitation of 26 manholes and one junction structure. Concurrent work by the Illinois Department of Transportation (IDOT) along Illinois Route 53 (IL-53) has prevented the contractor from completing the planned lining and manhole rehabilitation work due to the prolonged inaccessibility of the work area as a result of IDOT’s work.
As IDOT has not provided a definitive schedule for restoring access to this area, the District has determined that the remaining work beneath IL-53 should be deleted from the contract scope and performed under a future contract when access to the work area can be coordinated. This change order provides for the deletion of the work associated with the sewer and manholes beneath IL-53. The deleted work includes cured-in-place pipe lining from Station 105+63 to Station 109+84, adjustment of the manhole at Station 109+84, rehabilitation of the manhole at Station 105+63, and rehabilitation of the junction structure at Station 109+84. The contractor submitted a cost proposal (CO-08) for an extra in the amount of $0.00 and a credit in the amount of $1,125,983.84, for a net credit in the amount of $1,125,983.84. 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 decrease Contract 11-404-3S in an amount of $1,125,983.84 (13.29% of the current contract value), from an amount of $8,470,659.74, to an amount not to exceed $7,344,675.90.
Funds will be restored to Account 401-50000-645700.
Requested, Catherine A. O’Connor, Director of Engineering, KMF:LS
Recommended, Darlene A. LoCascio, Director of Procurement and Materials Management
Respectfully Submitted, Precious Brady-Davis, Chairperson Committee on Procurement
