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 June 18, 2010, the attached list of change orders has been approved. The effect of these change orders resulted in an increase in the amount of $9,780.10 from the original amount awarded of $67,775,617.14. The current contract value is $67,785,397.24. The prior approved change orders reflect a 0.01% increase to the original contract value.
The contract requires the installation of survey monuments to allow measurement of permanent movement of the rock wall which separates the Thornton Reservoir and the Main Lobe of the Thornton Quarry. Upon installation of the survey monuments, the contractor uncovered subsurface conditions that are not compatible with the monument detail specified in the contract plans and specifications. Deep embedment survey monuments are required for the fractured rock encountered at the site. Additionally, two survey targets are required to measure movement of a key block on the south wall of the reservoir.
The contractor submitted a cost proposal (COR-2) for an extra in the amount of $38,054.10 and a credit in the amount of $6,340.00 for a net extra in the amount of $31,714.10, to install 21 deep embedment survey monuments and two survey targets. The engineer reviewed the proposal, found it reasonable, and stated via correspondence 115, 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 $31,714.10 (0.05% of the current contract value) from an amount of $67,785,397.24 to an amount not to exceed $67,817,111.34.
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
