Dear Sir:
On December 4, 2014, the Board of Commissioners authorized the Director of Procurement and Materials Management to award Contract 04-128-3P Westside Primary Settling Tanks 1-9 and Aerated Grit Facility, Stickney Water Reclamation Plant, to IHC Construction and F.H. Paschen/S.N. Nielsen Joint Venture, in an amount not to exceed $224,760,000.00, plus a five (5) percent allowance for change orders in an amount of $11,238,000.00, for a total amount not to exceed $235,998,000.00.

An extra in an amount of $310,812.66 to modify the chain drives for the grit conveyors at the Aerated Grit Facility. The chains have repeatedly failed due to excessive stresses on the chains and sprockets. Also, freezing weather has been preventing the exterior chain drives from running smoothly. Therefore, it will be necessary to replace the chains and sprockets, and to run power to the exterior chain drive enclosures for freeze protection. Since this work is critical to the schedule, and the engineer and contractor are unable to reach an agreement on cost, the engineer has determined that this work should be tracked on a Time and Material basis with a not to exceed value based on the contractor’s cost proposal. Therefore, the Engineering Department is recommending approval of COR-01 for an extra in an amount not to exceed $310,812.66.
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 04-128-3P in an amount of $310,812.66 (0.13% of the current contract value), from an amount of $233,792,251.98, to an amount not to exceed $234,103,064.64.
Funds are available in Account 401-50000-645650.
Requested, Catherine A. O’Connor, Director of Engineering, GR:PO’B:JSS
Recommended, Darlene A. LoCascio, Director of Procurement and Materials Management
Respectfully Submitted, Barbara J. McGowan, Chairman Committee on Procurement
