Body
Dear Sir:
On July 14, 2011, the Board of Commissioners authorized the Director of Procurement and Materials Management to award Contract 06-023-3P Stop Logs and Diversion Pumps at Wilmette Pump Station and Evanston Pump Station Rehabilitation, North Service Area, to F.H. Paschen/S.N. Nielsen, in an amount not to exceed $17,440,000.00. The scheduled contract completion date was October 11, 2013.
As of July 10, 2015, the attached list of change orders has been approved. The effect of these change orders resulted in an increase in the amount of $527,388.96 from the original amount awarded of $17,440,000.00. The current contract value is $17,967,388.96. The prior approved change orders reflect a 3.02% increase to the original contract value.
This contract was substantially complete on October 7, 2013. Since substantial completion, a myriad of warranty and punch list items, mostly pertaining to electrical and instrumentation, surfaced during the operation and testing of the station. These issues required investigation and trial and error approaches to remediate before the contract could be finally closed out. These issues have been solved; however, a design inadequacy with the lake diversion gates has been discovered during the summer operation. The originally specified gaskets on the slide gates are inadequate for the application and are being ripped off of the gate after minimal gate operation. An extra in the amount of $68,752.19 is needed to furnish and install modified upper gaskets on the slide gates at the Wilmette Pump Station. The scope of work includes furnishing ten custom upper gaskets, installation hardware, and the labor to install the new custom gaskets, which includes re-machining the existing gates. The new custom gaskets will provide a reliable gate seal with the appropriate maintenance expectations. Upon completion of this work, the contract will be closed. The contractor submitted a cost proposal (CCO-024) for an extra in the amount of $68,752.19. The engineer reviewed the proposal, found it to be reasonable, and stated via correspondence 725 that the Engineering Department would recommend its approval.
This change order is in compliance with the Illinois Criminal Code since the change is germane to the contract.
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 06-023-3P in an amount of $68,752.19 (0.38% of the current contract value), from an amount of $17,967,388.96, to an amount not to exceed $18,036,141.15.
Funds are available in Accounts 101-50000-612620, 401-50000-645620 and 645720.
Requested, Catherine O’Connor, Director of Engineering, MVL:ECB
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 August 6, 2015
