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 was February 1, 2011.
As of November 4, 2011, the attached list of change orders has been approved. The effect of these change orders resulted in an increase in the amount of $2,413,323.46 from the original amount awarded of $28,490,000.00. The current contract value is $30,903,323.46. The prior approved change orders reflect an 8.47% increase to the original contract value.
The contract drawings show three new underground lines (steam, condensate and city water) to be routed from the southwest corner of the Pump and Blower Building to a pit in the northeast corner of the Heavy Equipment Storage Building, through the former site of the Ferric Chloride Building. The foundation of the Ferric Chloride Building was only partially demolished which left the remaining portion obstructing the proposed path of the new underground lines. The engineer determined that a slightly revised route, which avoided the remaining foundation, was required. In addition, grading changes are required to a new berm in the area that was designed to replace the Ferric Chloride Building so as to avoid a live 13.2 KV junction box that remains.
The contractor submitted a cost proposal (CCO-056) for an extra in the amount of $15,943.42. The engineer reviewed the proposal, found it reasonable, and stated via correspondence 818, 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.
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 $15,943.42 (0.05% of the current contract value) from an amount of $30,903,323.46 to an amount not to exceed $30,919,266.88.
Funds are available in Accounts 101-50000-612680, 401-50000-645680 and 645780.
Requested, Kenneth A. Kits, Director of Engineering, TEK:JW
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 17, 2011
