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 December 16, 2011, the attached list of change orders has been approved. The effect of these change orders resulted in an increase in the amount of $3,677,250.62 from the original amount awarded of $67,775,617.14. The current contract value is $71,452,867.76. The prior approved change orders reflect a 5.43% increase to the original contract value.
Upon excavating the upper elevations of the Gap Dam abutments, highly fractured rock was discovered. In some areas, additional means of controlling seepage other than grouting may be necessary. This change order is for the excavation, surveying and backfilling of ten test pits, along the Gap Dam abutments, to characterize the depth of the fractured rock. The results will be evaluated to determine the impacts to the current design and assess whether additional seepage control measures are necessary. Should it be determined that other seepage control measures are necessary, a separate change order request will be initiated for the additional scope of work.
The contractor submitted a cost proposal (CCO-016) for an extra in an amount of $40,370.00. The engineer reviewed the proposal, and stated via correspondence 652, that the Engineering Department would recommend its approval for time and material costs not to exceed $40,370.00.
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 $40,370.00 (0.06% of the current contract value) from an amount of $71,452,867.76 to an amount not to exceed $71,493,237.76.
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
