Body
Dear Sir:
On December 2, 2010, the Board of Commissioners authorized the Director of Procurement and Materials Management to award Contract 04-203-4F Final Reservoir Preparation, Thornton Composite Reservoir, Calumet Service Area, to Walsh/II in One, Joint Venture, in an amount not to exceed $50,763,937.00. This contract was substantially completed on December 24, 2015.
As of March 6, 2020, the attached list of change orders has been approved. The effect of these change orders resulted in an increase in an amount of $3,163,074.47 from the original amount awarded of $50,763,937.00. The current contract value is $53,927,011.47. The prior approved change orders reflect a 6.23% increase to the original contract value.
Item 1: The contract documents specified quarry stones to be placed along the edge of the lower access ramp in lieu of a guardrail. The District determined the stones that were placed by the contractor were large enough in mass to not require the specified drilled rock dowel anchorage. This change order includes a credit for the installation of 1"-diameter epoxy-coated rock dowels. The contractor submitted a cost proposal (CCO-022) for a credit in the amount of $27,615.13. The engineer reviewed the proposal, found it to be reasonable, and stated via correspondence 862 that the Engineering Department would recommend its approval.
Item 2: IDOT requested that the District remove landscape material along the west side of Vincennes Avenue due to line of sight concerns. In order to ensure safe conditions for contractors, the outside southbound lane of Vincennes Avenue was closed. This change order includes an extra for the installation and maintenance of traffic control measures for 45 days to complete the landscape work. The contractor submitted a cost proposal (CCO-030) for an extra in the amount of $5,934.00. The engineer reviewed the proposal, found it to be reasonable, and stated via correspondence 832 that the proposal was approved.
The above two change orders are in compliance with the Illinois Criminal Code since the changes are germane to the contract.
It is hereby recommended that the Board of Commissioners authorize the Director of Procurement and Materials Management to execute two change orders to decrease Contract 04-203-4F in an amount of $21,681.13 (0.04% of the current contract value), from an amount of $53,927,011.47, to an amount not to exceed $53,905,330.34.
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
Disposition of this agenda item will be documented in the official Regular Board Meeting Minutes of the Board of Commissioners for April 16, 2020
