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 February 5, 2016, the attached list of change orders has been approved. The effect of these change orders resulted in an increase in an amount of $5,064,948.87 from the original amount awarded of $162,232,344.00. The current contract value is $167,297,292.87. The prior approved change orders reflect a 3.12% increase to the original contract value.
Credit work is required to delete certain contract work due to the new Contract 15-120-3P Conversion of Old GCTs to WASSTRIP Process being issued. This contract will reuse many elements of the existing Southwest Concentration Facility, which were scheduled to be removed under 09-176-3P. The scope of work to be credited from Contract 09-176-3P includes deletion of removal of sludge collector mechanisms, electrical wiring, and tank covers from Concentration Tanks 7-16, deletion of installation of groundwater pressure relief valves from these tanks, deletion of the removal of a 12” sludge line in the lower operating gallery, deletion of installation of a 12” effluent water line in the location of this sludge line, deletion of the removal of diffuser plates and concrete fillet blocks in the sludge influent channel, deletion of concrete patches for the floor in the upper operating gallery, deletion of the removal of influent valves to Concentration Tanks 1-4, and other related work. The contractor submitted a cost proposal (CCO-226) for a credit of in the amount of $272,008.42. The engineer reviewed the proposal, found it to be reasonable, and stated via correspondence 5926 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 decrease Contract 09-176-3P, in an amount of $272,008.42 (0.16% of the current contract value), from an amount of $167,297,292.87, to an amount not to exceed $167,025,284.45.
Funds are to be restored to Account 401-50000-645650.

Recommended, Darlene A. LoCascio, Director of Procurement and Materials Management
Respectfully Submitted, Barbara J. McGowan, Chairman Committee on Procurement
