Title
Authority to increase Contract 03-RFP-03 (73-161-CH) McCook Reservoir Overburden Removal Lawndale Avenue Solids Management Area, to Walsh Construction Company of Illinois, in the amount of $49,445.50, from an amount of $63,618,456.50, to an amount not to exceed $63,667,902.00, Account 401-50000-645620, Purchase Order 5000113
Body
Dear Sir:
On September 4, 2003 the Board of Commissioners passed an order authorizing the Purchasing Agent to award Contract 03-RFP-03 (73-161-CH), to Walsh Construction Company of Illinois in an amount not to exceed $58,770,500.00. The contract terms called for the completion of all work by September 5, 2007. This contract is still in progress.
As of August 1, 2008 the attached list of Change Orders has been approved. The effect of these Change Orders resulted in an increase in the amount of $4,847,956.50 from the original amount awarded of $58,770,500.00. The current contract value is $63,618,456.50. The prior approved Change Orders reflect an 8.2% increase to the original contract value.
Construction of the temporary access ramp was authorized by the Board of Commissioners on June 19, 2008 to facilitate access to the Stage 1 reservoir while the permanent ramp is temporarily taken out of service by the Army Corps of Engineers to install the grout curtain and slurry wall. Upon completion of the temporary access ramp at Lagoon 8, excessive seepage and wet conditions necessitated that additional maintenance be performed on the ramp in order to keep it navigable. It was also necessary to construct an under-drain system to channel groundwater away from the ramp’s surface.
The contractor submitted a cost proposal (COR-009) in the amount of $50,307.75. After reviewing the contractor’s proposal and performing an independent estimate, the District counter-proposed in an amount of $49,445.50 (FL-200). The contractor accepted the District’s proposal (WC-084A). The District now recommends approval for the above extra.
This Change Order is in compliance with the Illinois Criminal Code, since it is due to circumstances not reasonably foreseeable and is in the best interest of the District.
It is hereby requested that the Board of Commissioners authorize the Purchasing Agent to execute this Change Order in an amount not to exceed $49,445.50 (.08% of the original contract value) from an amount of $63,618,456.50, to an amount not to exceed $63,667,902.00.
Funds are available in Account 401-50000-645620.
Requested, Joseph Sobanski, Chief Engineer, NV:MVL
Recommended, Darlene A. LoCascio, Purchasing Agent
Respectfully Submitted, Barbara J. McGowan, Chairman Committee on Purchasing
