Body
Dear Sir:
On December 20, 2007, the Board of Commissioners authorized the Director of Procurement and Materials Management to award Contract 04-125-3S (Re-Bid) Upper Des Plaines Pumping Station Rehabilitation and TARP Connection, SSA, to F.H. Paschen/S.N. Nielsen and Associates LLC, in an amount not to exceed $11,756,000.00. The contract documents specify a completion date of April 8, 2009. This contract is still in progress.
As of June 23, 2009 one change order has been approved, as listed in the attached change order log report. The effect of this change order resulted in a decrease in an amount of $3,016,653.00 from the original amount awarded of $11,756,000.00. The current contract value is $8,739,347.00. The prior approved change order reflects a 25.7% decrease to the original contract value.
The contract documents include the modification of backflow gates at 16 locations along the Des Plaines Tunnel System. Upon inspection of drop shafts at DS-12I and DS-91, it was discovered that a backflow gate at each of these drop shafts is missing. Therefore, the change order to the contract is necessary to fabricate and install timber backflow gates for drop shafts DS-12I and DS-91 so that the diversion structures can operate as intended.
Additionally, the contract documents call for the replacement of gate hangers for one of the timber backflow gates included in the sluice gate control structure for drop shaft DS-19,23. However, there are two backflow gates in the structure. The change order also includes the installation of new gate hangers for the second gate in the structure at drop shaft DS-19,23.
This change order is in compliance with the Illinois Criminal Code since the change is due to circumstances 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 a change order to increase Contract 04-125-3S (Re-Bid) in an amount of $48,615.24 (0.6% of the current contract value) from an amount of $8,739,347.00 to an amount not to exceed $8,787,962.24.
Funds are available in Accounts 401-50000-645600 and 401-50000-645700.
Requested, Joseph P. Sobanski, Director of Engineering, NV:MVL
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 July 9, 2009
