Body
Dear Sir:
On May 6, 2010, the Board of Commissioners authorized the Director of Procurement and Materials Management to award Contract 04-202-4F Connecting Tunnels & Gates, Thornton Composite Reservoir, Calumet Service Area, to Walsh/II in One, Joint Venture, in an amount not to exceed $135,475,200.00. The scheduled contract completion date was May 14, 2015. The anticipated contract completion date is December 10, 2015.
As of June 5, 2015, the attached list of change orders has been approved. The effect of these change orders resulted in an increase in an amount of $1,102,470.92 from the original amount awarded of $135,475,200.00. The current contract value is $136,577,670.92. The prior approved change orders reflect a 0.81% increase to the original contract value.
The contractor requested to increase the diffuser slab panel lengths from 32 feet, as specified in the contract, to 64 feet in order to minimize the slab construction time. Although the overall dimensions of the diffuser slab do not change, this modification results in a reduction in the overall number of panels to pour and the total length of the construction joints required for the diffuser slab. The contractor submitted a cost proposal (CCO-10) for a credit in the amount of $20,562.23. The Engineer reviewed the proposal, found it reasonable, and stated via correspondence 1531, 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 decrease Contract 04-202-4F in an amount of $20,562.23 (0.02% of the current contract value), from an amount of $136,577,670.92, to an amount not to exceed $136,557,108.69.
Funds will be restored in Account 401-50000-645600.
Requested, Catherine A. O'Connor, Director of Engineering, WSS:KMF
Recommended, Darlene A. LoCascio, Director of Procurement and Materials Management
Respectfully Submitted, Barbara J. McGowan, Chairman Committee on Procurement
