Body
Dear Sir:
On March 7, 2013, the Board of Commissioners authorized the Director of Procurement and Materials Management to award Contract 06-494-3P Centrifuge Building and Sludge Loading System Upgrades at the Egan Water Reclamation Plant and the Hanover Park Water Reclamation Plant, North Service Area, to IHC Construction Companies, LLC, in an amount not to exceed $9,044,000.00. The scheduled contract completion date was March 25, 2015.
As of July 7, 2017, the attached list of change orders has been approved. The effect of these change orders resulted in an increase in an amount of $221,783.40 from the original amount awarded of $9,044,000.00. The current contract value is $9,265,783.40. The prior approved change orders reflect a 2.45% increase to the original contract value.
This change order involves the removal and replacement of the drive end shafts, tail end shafts and two pillow block bearings associated with the reversible screw conveyor. During the replacement of the intermediate bearing assembly, it was noted that the drive and tail end shafts were the only remaining carbon steel parts of the screw conveyor and that some lateral movement had been occurring. The replacement of these shafts with stainless steel will avoid future corrosion and shall be grooved to prevent the lateral movement. This work shall ensure the reliable operation of this screw conveyor, which is essential for centrifuge and ANITAMox operations. The contractor submitted a cost proposal (CCO-030) for an extra in the amount of $22,466.10. The engineer reviewed the proposal, found it to be reasonable, and stated via correspondence 687, that the Engineering Department would recommend its approval.
This change order is in compliance with the Illinois Criminal Code since the change is germane to the original contract as signed.
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 06-494-3P in an amount of $22,466.10 (0.24% of the current contract value), from an amount of $9,265,783.40, to an amount not to exceed $9,288,249.50.
Funds are available in Account 401-50000-645650.
Requested, Marcella V. Landis, Acting Director of Engineering, ECB:GR
Recommended, Darlene A. LoCascio, Director of Procurement and Materials Management
Respectfully Submitted, Barbara J. McGowan, Chairman Committee on Procurement
