Title
Authority to decrease Contract 09-176-3P Sludge Thickening Facilities, Stickney Water Reclamation Plant, to McHugh Construction in an amount of $11,245.06, from an amount of $164,334,866.56, to an amount not to exceed $164,323,621.50, 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 April 12, 2014.
As of May 4, 2012, the attached list of change orders has been approved. The effect of these change orders resulted in an increase in an amount of $2,102,522.56 from the original amount awarded of $162,232,344.00. The current contract value is $164,334,866.56. The prior approved change orders reflect a 1.30% increase to the original contract value.
Additional work is required to revise the insulation requirements for the Area 32 - Bio-Filters pipe galleries. Contract drawings specify the installation of rigid insulation in the Area 32 pipe galleries over the structural slab with a topping slab applied over the insulation. Installation of the rigid insulation will not allow for proper fitting of access hatches. Therefore, the requirement to provide the rigid insulation should be deleted. In lieu of the rigid insulation, a 1" thick heavy duty insulation should be mechanically attached to the interior face of the concrete ceiling and walls of the pipe galleries. The contractor submitted a cost proposal (CCO-061) for an extra in the amount of $22,894.88 and a credit in the amount of $34,139.94, for a net credit in the amount of $11,245.06. The engineer reviewed the proposal, found it to be reasonable, and stated via correspondence 2838, 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 decrease Contract 09-176-3P in an amount of $11,245.06 (0.01% of the current contract value) from an amount of $164,334,866.56 to an amount not to exceed $164,323,621.50.
Funds will be restored in Account 401-50000-645650.
Requested, Thomas E. Kunetz, Assistant Director of Engineering, TEK:ECB
Recommended, Darlene A. LoCascio, Director of Procurement and Materials Management
Respectfully Submitted, Barbara J. McGowan, Chairman Committee on Procurement
