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 $100,619.00, from an amount of $165,453,952.83, to an amount not to exceed $165,554,571.83, 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, 2015.
As of August 9, 2013, the attached list of change orders has been approved. The effect of these change orders resulted in an increase in an amount of $3,221,608.83 from the original amount awarded of $162,232,344.00. The current contract value is $165,453,952.83. The prior approved change orders reflect a 1.99% increase to the original contract value.
Item 1: An extra in the amount of $64,390.54 to provide conduit and wiring to the low and high pressure switches on Sludge Feed Pumps Nos. 1-5 in the Area 60, Sludge Blending Facility. The contract erroneously omitted the electrical connections to the pressure switches. To ensure safe pump operation and to prevent damage to the pumps, operational pressure switches are required. The contractor submitted a cost proposal (CCO-101) foran extra in the amount of $64,390.54. The engineer reviewed the proposal, found it to be reasonable, and stated via correspondence 3840, that the Engineering Department would recommend its approval.
This change order is in compliance with the Illinois Criminal Code since the changes are germane to the contract.
Item 2: An extra in the amount of $36,228.46 to perform additional work in the concrete channels upstream and downstream of the sludge screens in the Sludge Control Building. The existing concrete channels have spalled and degraded and the sluice gates cannot be installed to provide a water tight connection. In addition to this, it has been determined that the walls are not true and vertical. The additional work includes saw-cutting, chipping and grinding the existing channel walls to provide true surfaces on which to mount the gates, providing non-shrink epoxy grout to seal the gate frames in place, and increasing the height of the stainless steel weir plates on the gates to the correct hydraulic elevation. The contractor submitted a cost proposal (CCO-164) for an extra in the amount of $36,228.46. The engineer reviewed the proposal, found it to be reasonable, and stated via correspondence 3923, 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 are 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 09-176-3P in an amount of $100,619.00 (0.06% of the current contract value), from an amount of $165,453,952.83, to an amount not to exceed $165,554,571.83.
Funds are available in Account 401-50000-645650.

Respectfully Submitted, Barbara J. McGowan, Chairman Committee on Procurement
