Mr. David St. Pierre, Executive Director
Title
Authority to increase Contract 09-176-3P Sludge Thickening Facilities, Stickney Water Reclamation Plant, to McHugh Construction in an amount of $19,703.05, from an amount of $166,354,653.19, to an amount not to exceed $166,374,356.24, Account 401-50000-645650, Purchase Order 5001115
Body
Dear Sir:
On March 18, 2010, the Board of Commissioners authorized the Director of Procurement and Materials Management to award Contract 09-176-3P Sludge Thickening Facilities, Stickney Water Reclamation Plant, to McHugh Construction, in an amount not to exceed $162,232,344.00. The scheduled contract completion date is November 11, 2016.
As of September 5, 2014, the attached list of change orders has been approved. The effect of these change orders resulted in an increase in an amount of $4,122,309.19 from the original amount awarded of $162,232,344.00. The current contract value is $166,354,653.19. The prior approved change orders reflect a 2.54% increase to the original contract value.
Additional work is required to remove, repair, and reinstall Waste Activated Sludge (WAS) Pump 2. The pump was prematurely damaged while operating with low seal water pressure. The effluent seal water pressure was reduced by an unexpected excess quantity of slimy particulate matter in the effluent water source, which clogged the strainer systems. The additional work includes removal and reinstallation of WAS Pump 2, shipment to and from the manufacturer machine shop, and repairing damaged parts in the pump. This work has been completed. Before the engineer's determination on the change order, the contractor proceeded at his own risk with this work as determined in his own best interest in executing the overall contract. The engineer has now concluded that this is additional work due to unanticipated field conditions. The contractor submitted a cost proposal (CCO-197) of an extra in the amount of $19,703.05. The engineer reviewed the proposal, found it to be reasonable, and stated via correspondence 4937, that the Engineering Department would recommend its approval.
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 09-176-3P in an amount of $19,703.05 (0.012% of the current contract value), from an amount of $166,354,653.19 to an amount not to exceed $166,374,356.24.
Funds are available in Account 401-50000-645650.
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
