Body
Dear Sir:
On May 18, 2006, the Board of Commissioners passed an order authorizing the Purchasing Agent to award Contract 73-161-FH Vulcan Conveyance System and Maintenance Facilities, McCook CUP Reservoir, to Graycor Industrial Contractors, Inc. in an amount not to exceed $29,387,000.00. The contract terms called for the completion of all work by August 29, 2007. This contract is still in progress.
As of June 9, 2008, the attached list of Change Orders has been approved. The effect of these Change Orders resulted in an increase in an amount of $854,436.58 from the original amount awarded of $29,387,000.00. The current contract value is $30,241,436.58. The prior approved Change Orders reflect a 2.9% increase to the original contract value.
Item 1: An extra in an amount not to exceed $22,866.80 for the installation of an additional 600 feet of aerial cable for Conveyors A and B.
The quantity of cable shown on sheet E-123 of the Contract Plans was 600 feet less than required.
The contractor submitted a cost proposal (COR-54) in the amount of $22,866.80. After reviewing the contractor’s proposal and performing an independent estimate, the District accepted the proposal (FL-414). The District now recommends approval for the above extra work.
Item 2: A credit in an amount not to exceed $62,040.00 for certain portions of the site electrical work that could not be installed due to conflicts with the slurry wall work being performed by the Army Corps of Engineers. Materials and equipment delivered to the site for this work will be turned over to the District and need to be installed at a later date.
The contractor submitted a cost proposal (COR-60) in the amount of $62,040.00. After reviewing the contractor’s proposal and performing an independent estimate, the District accepted the proposal (FL-446). The District now recommends approval for the above credit.
Item 3: An extra in an amount not to exceed $16,394.59 for additional stone fill to facilitate access to the crusher area.
The contractor submitted a cost proposal (COR-26) in the amount of $28,226.16. After reviewing the contractor’s proposal and performing and independent estimate, the District rejected the proposal (FL-427 and FL 443). The contractor accepted the District’s counter-proposal of $16,394.59 via GICI-209. The District now recommends approval for the above extra.
All three of these Change Orders are in compliance with the Illinois Criminal Code, since the Change Order is due to circumstances not reasonably foreseeable, and are in the best interest of the District.
It is hereby requested that the Board of Commissioners authorize the Purchasing Agent to execute three Change Orders, one for an extra in an amount not to exceed $22,866.80, one for a credit in an amount not to exceed $62,040.00, and one for an extra in an amount not to exceed $16,394.59, consisting of a decrease to Contract 73-161-FH in a total amount of $22,778.61 (.08% of the current contract value) from an amount of $30,241,436.58 to an amount not to exceed $30,218,657.97.
Funds will be restored in Account 401-50000-645620.
