Nielsen/IHC Construction Joint Venture, in an amount of $75,354.64, from an amount of $230,436,029.29, to an amount not to exceed $230,511,383.93, Account 401-50000-645650, Purchase Order 5000954
Body
Dear Sir:
On November 6, 2008, the Board of Commissioners authorized the Director of Procurement and Materials Management to award Contract 07-220-3P Primary Settling Tanks and Grit Removal Facilities, to F.H. Paschen/S.N. Nielsen/IHC Construction, Joint Venture, in an amount not to exceed $228,474,000.00. The scheduled contract completion date is November 18, 2012.
As of June 4, 2010, the attached list of change orders has been approved. The effect of these change orders resulted in an increase in the amount of $1,962,029.29 from the original amount awarded of $228,474,000.00. The current contract value is $230,436,029.29. The prior approved change orders reflect a 0.86% increase to the original contract value.
Item 1: An extra in the amount of $53,183.56 to remove and replace three existing effluent water valves and vaults at STA. 4+41. Contract drawing C-758 shows replacement of the effluent water line along ‘D’ Street; however, the drawing does not require the replacement of the three existing 8” valves and corresponding vaults. These valves are necessary for proper system isolation, and need to be replaced. The contractor submitted a cost proposal (COR-75) for an extra in the amount of $53,183.56. The engineer reviewed the proposal, found it reasonable, and stated via correspondence 1543, that the Engineering Department would recommend its approval.
The above change order is in compliance with the Illinois Criminal Code since the changes are germane to the contract as signed.
Item 2: An extra in the amount of $22,171.08 to provide modifications to the new Tunnel A extension and 12 inch sludge line. An unknown concrete wall was discovered during the construction of the Tunnel A Extension. This wall is part of an existing concrete sewer chamber that was not identified on the contract drawings and prohibits the construction of the new Tunnel A extension structure and 12 inch sludge line. The work includes modifying the Tunnel A extension concrete wall to accommodate the existing sewer structure, relocating the Tunnel A extension expansion joint, and rerouting the 12 inch sludge line. The contractor submitted a proposal (COR-81) in the amount of $22,171.08. The engineer reviewed the proposal, found it to be reasonable, and stated via correspondence 1527, that the Engineering Department would recommend its approval.
The above change order is in compliance with the Illinois Criminal Code since the change is due to circumstances that were not 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 two change orders to increase Contract 07-220-3P, in an amount of $75,354.64 (0.03% of the current contract value), from an amount of $230,436,029.29 to an amount not to exceed $230,511,383.93.
Funds are available in Account 401-50000-645650.
Requested, Kenneth A. Kits, Director of Engineering, TEK:ECB
Recommended, Darlene A. LoCascio, Director of Procurement and Materials Management
Respectfully Submitted, Barbara J. McGowan, Chairman Committee on Procurement
