Body
Dear Sir:
On December 3, 2009, the Board of Commissioners authorized the Director of Procurement and Materials Management to award Contract 04-201-4F, Tollway Dam, Grout Curtain and Quarry Plugs, Thornton Composite Reservoir, Calumet Service Area, to F.H. Paschen, S.N. Nielsen and Associates LLC, and Cabo Construction Corporation, Joint Venture, in an amount not to exceed $67,775,617.14. The scheduled contract completion date is May 25, 2014.
As of January 6, 2012, the attached list of change orders has been approved. The effect of these change orders resulted in an increase in the amount of $3,716,056.97 from the original amount awarded of $67,775,617.14. The current contract value is $71,491,674.11. The prior approved change orders reflect a 5.48% increase to the original contract value.
Upon excavating the east and west abutments of the Roller Compacted Concrete (RCC) Gap Dam, fractured rock was discovered at the upper portion of the excavations. This change order is for additional work to install straight vertical formwork, founded on sound rock, along the east and west abutments of the RCC Gap Dam, against which RCC can be placed. An additional change order will be required in the spring to place concrete where the fractured rock was removed.
The contractor submitted a cost proposal (CCO-013) for an extra in an amount of $40,293.71. The engineer reviewed the proposal, found it reasonable, and stated via correspondence 667, 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 04-201-4F in an amount of $40,293.71 (0.06% of the current contract value) from an amount of $71,491,674.11 to an amount not to exceed $71,531,967.82.
Funds are available in Account 401-50000-645620.
Requested, Kenneth A. Kits, Director of Engineering, WSS:KMF
Recommended, Darlene A. LoCascio, Director of Procurement and Materials Management
Respectfully Submitted, Barbara J. McGowan, Chairman Committee on Procurement
