Body
Dear Sir:
On September 2, 2010, the Board of Commissioners authorized the Director of Procurement and Materials Management to award Contract 07-168-3P Scum Concentration, Centrifuge Building, Preliminary & Imhoff Tanks, Elevator Improvements, Diffuser Plates and Trailer Replacement, Stickney Service Area, LASMA, to IHC Construction Companies, LLC, in an amount not to exceed $23,544,400.00. The scheduled contract completion date was September 16, 2012.
As of October 19, 2012, the attached list of change orders has been approved. The effect of these change orders resulted in a decrease in an amount of $121,678.25 from the original amount awarded of $23,544,400.00. The current contract value is $23,422,721.75. The prior approved change orders reflect a 0.52% decrease to the original contract value.
Item 1: A decrease in the amount of $81,609.81 for pipe expansion box modifications to be performed under a future contract along with the work from CCO-006. The contract requires modifications to the existing expansion boxes of Battery C while the pipes within the boxes are being replaced. The pipe replacement work has been removed from the contract per CCO-006. Performing the expansion box repairs with the existing pipes in place could cause the pipes to fail, therefore the work described in RFQ-23 is recommended to be performed under a future contract along with the work from CCO-006. The contractor submitted a revised cost proposal (CCO-023) for a credit in the amount of $81,609.81. The engineer reviewed the proposal, found it reasonable, and stated via correspondence 520, that the Engineering Department would recommend its approval.
Item 2: An extra in the amount of $11,102.88 to repair the expansion joint in the Stickney Aeration Battery D West Influent Conduit. The revisions were necessary to seal an expansion joint of the West Influent Conduit, which was leaking into an empty adjoining conduit. The repair location was made accessible for a limited time due to the entire battery being empty for contract work, therefore, the work was issued for an amount not to exceed $9,999.00 under the Director of Engineering's signature. The contractor has completed this work at his own risk and submitted verified time and material records in cost proposal (CCO-024) for an extra in the amount of $11,102.88. The engineer reviewed the proposal, found it reasonable and stated via correspondence 493, that the Engineering Department would recommend its approval.
The above two change orders are in compliance with the Illinois Criminal Code since the changes are due to circumstances that were not reasonably foreseeable at the time the contract was signed, and are 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 the above two change orders to decrease Contract 07-168-3P in an amount of $70,506.93 (0.30% of the current contract value), from an amount of $23,422,721.75, to an amount not to exceed $23,352,214.82.
Funds will be restored to Accounts 401-50000-645750 and 645780.
Requested, Catherine A. O'Conner, Director of Engineering, MVL:JKK
Recommended, Darlene A. LoCascio, Director of Procurement and Materials Management
Respectfully Submitted, Barbara J. McGowan, Chairman Committee on Procurement
Disposition of this agenda item will be documented in the official Regular Board Meeting Minutes of the Board of Commissioners for November 1, 2012
