Body
Dear Sir:
On December 18, 2008, the Board of Commissioners authorized the Director of Procurement and Materials Management to award contract 01-198-AD Demolition of Sludge Disposal Building and Rehabilitation of Pump and Blower House and Coarse Screen Building at the Stickney Water Reclamation Plant, to IHC Construction Companies, LLC, in an amount not to exceed $28,490,000.00. The scheduled contract completion date is February 1, 2011.
As of May 21, 2010, the attached list of change orders has been approved. The effect of these change orders resulted in an increase in the amount of $1,830,802.20 from the original amount awarded of $28,490,000.00. The current contract value is $30,320,802.20. The prior approved change orders reflect a 6.43% increase to the original contract value.
Item 1: An extra in the amount of $22,514.31, for repairing cracks and waterproofing the interior of the Battery A Effluent Conduit. While the conduit was dewatered, the contractor identified approximately 110 linear feet of crack repairs and 80 square feet of concrete patching that was necessary to perform in order to maintain the integrity of the structure. The contractor submitted a cost proposal (CCO-26) for an extra in the amount of $22,514.31, after he completed the work at his own risk as determined in his best interest in executing the overall contract. The engineer reviewed the proposal, found it reasonable, and stated via correspondence 498, that the Engineering Department would recommend its approval.
Item 2: A net credit in the amount of $1,420.77, to delete the demolition of two large ducts located near the ceiling in the Pump and Blower House and to install two new louvers where the ducts penetrate a new exterior wall. The contractor submitted a cost proposal (CCO-23) for an extra in the amount of $12,835.90 and a credit of $14,256.67 for a net credit in the amount of $1,420.77. The engineer reviewed the proposal, found it reasonable, and stated via correspondence 502, that the Engineering Department would recommend its approval.
Item 3: An extra in the amount of $14,460.77, for the rerouting of the 4” phone conduit located in the AB tunnel. This work was necessary because it would conflict with the future tunnel rehabilitation work planned under contract 04-131-2D. The contractor submitted a cost proposal (CCO-27) for an extra in the amount of $14,460.77. The engineer reviewed the proposal, found it reasonable, and stated via correspondence 419, that the Engineering Department would recommend its approval.
The above three change orders are 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 01-198-AD in an amount of $35,554.31 (0.12% of the current contract value) from an amount of $30,320,802.20 to an amount not to exceed $30,356,356.51.
Funds are available in Accounts 101-50000-612680, 401-50000-645680, and 645780.
Requested, Kenneth A. Kits, Director of Engineering, TEK:JKK

Respectfully Submitted, Barbara J. McGowan, Chairman Committee on Procurement
