Title
Authority to increase Contract 11-403-2P Membrane Gas Holder Replacement and Digester Cleaning, Egan Water Reclamation Plant, to Path Construction Company, Inc. in an amount of $96,765.00, from an amount of $5,878,167.09, to an amount not to exceed $5,974,932.09, Account 201-50000-645750, Purchase Order 4000018
Body
Dear Sir:
On November 6, 2014, the Board of Commissioners authorized the Director of Procurement and Materials Management to award Contract 11-403-2P Membrane Gas Holder Replacement and Digester Cleaning, Egan Water Reclamation Plant, to Path Construction Company, Inc., in an amount not to exceed $4,582,200.00. The scheduled contract completion date was August 4, 2017.
As of November 17, 2017, the attached list of change orders has been approved. The effect of these change orders resulted in an increase in the amount of $1,295,967.09 from the original amount awarded of $4,582,200.00. The current contract value is $5,878,167.09. The prior approved change orders reflect a 28.28% increase to the original contract value.
This contract involves the emptying and cleaning of digesters which are partially below grade. A groundwater relief valve prevents groundwater from building up a large enough differential pressure, when the tank is emptied, to cause damage to the tank. A unit price was included in the contract to account for any extra pumping that would be required to empty and clean the tanks. During the cleaning it was discovered that some of the relief valves were stuck in an open position, allowing groundwater to enter the digester and increasing the expected pumping volume. The pumping required to empty these tanks exceeded the unit price quantity included in the contract. The contractor submitted a claim and came to agreement with the Engineering Department on the terms and quantity of excess pumping that would be considered as extra work. The contractor submitted a cost proposal (CCO-010) for an extra in the amount of $96,765.00 and agreed that no additional compensation for general conditions job cost or delay will be claimed. The engineer reviewed the proposal, found it to be reasonable, and stated via correspondence 391, that the Engineering Department would recommend its approval.
This change order is in compliance with the Illinois Criminal Code since the changes are 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 11-403-2P in an amount not to exceed $96,765.00 (1.65% of the current contract value), from an amount of $5,878,167.09, to an amount not to exceed $5,974,932.09.
Funds are available in Account 201-50000-645750.
Requested, Marcella V. Landis, Acting Director of Engineering, ECB:GR
Recommended, Darlene A. LoCascio, Director of Procurement and Materials Management
Respectfully Submitted, Barbara J. McGowan, Chairman Committee on Procurement
