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 August 13, 2010, the attached list of change orders has been approved. The effect of these change orders resulted in an increase in the amount of $1,686,918.20 from the original amount awarded of $67,775,617.14. The current contract value is $69,462,535.34. The prior approved change orders reflect a 2.49% increase to the original contract value.
The contract requires a guardrail to be installed on the ramp along the north wall of the reservoir, with a minimum post foundation depth of 3’-6” below the existing surface. While coring post foundations, the contractor discovered that the depth to competent rock along the north wall ramp varies as the ramp consists of blasted rock benches that have been backfilled and graded. To ensure stable guardrail foundation posts, an additional depth of guardrail foundation post is required to reach competent rock.
The contractor submitted a cost proposal (COR-6) for an extra in an amount not to exceed $27,170.00, for additional depth of guardrail foundation posts, including drilling, rebar and concrete along the north wall ramp of the Thornton Composite Reservoir. Work completed will be paid on a unit cost basis not to exceed the value of the change order. The engineer reviewed the proposal, found it reasonable, and stated via correspondence 164, that the Engineering Department would recommend its approval.
This change order is in compliance with the Illinois Criminal Code since the change is due to circumstances nor reasonably foreseeable at the time the contract was signed, and is in the best interest of the District.
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 $27,170.00 (0.04% of the current contract value), from an amount of $69,462,535.34, to an amount not to exceed $69,489,705.34.
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
