Title
Authority to increase Contract 06-156-3P Grit Piping Replacement, Stickney Water Reclamation Plant to Independent Mechanical Industries, Inc. in an amount of $17,931.56, from an amount of $2,838,974.40 to an amount not to exceed $2,856,905.96, Account 401-50000-645750, Purchase Order 5000891
Body
Dear Sir:
On June 5, 2008, the Board of Commissioners authorized the Director of Procurement and Materials Management to award Contract 06-156-3P Grit Piping Replacement, Stickney Water Reclamation Plant to Independent Mechanical Industries, Inc. in an amount not to exceed $2,868,800.00. The contract terms called for the completion of all work by April 21, 2009. This contract is still in progress.
As of February 19, 2010, the attached list of change orders has been approved. The effect of these change orders resulted in a decrease in the amount of $29,825.60 from the original amount awarded of $2,868,800.00. The current contract value is $2,838,974.40. The prior approved change orders reflect a 1.04% decrease to the original contract value.
The contract includes the replacement of the existing permalloy grit piping with ceram-core piping. After the design stage was completed, an electrical conduit was run in the scum concentration tunnel under a separate contract. This created interference with the routing of the new grit pipe, which needed to be moved farther from the wall in order to accommodate the electrical conduit, while allowing sufficient access for personnel in the tunnel. At the entry of the scum concentration tunnel, an existing vertical scum pipe was found to be interfering with the ceram-core pipe. Therefore, it was necessary to relocate the scum pipe at the intersection of the two tunnels to provide clearance for the new grit pipe.
The contractor submitted a cost proposal (COR-4) in the amount of $17,931.56 to complete the work. The engineer reviewed the proposal, found it reasonable, and stated via correspondence 179, 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 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 06-156-3P in an amount of $17,931.56 (0.63% of the current contract value) from an amount of $2,838,974.40 to an amount not to exceed $2,856,905.96.
Funds are available in Account 401-50000-645750.
Requested, Joseph P. Sobanski, Director of Engineering, TEK:GR
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 March 4, 2010
