Nielsen/IHC Construction Joint Venture in an amount of $393,937.88, from an amount of $233,270,347.30, to an amount not to exceed $233,664,285.18, Account 401-50000-645650, Purchase Order 5000954
Body
Dear Sir:
On November 6, 2008, the Board of Commissioners authorized the Director of Procurement and Materials Management to award Contract 07-220-3P Primary Settling Tanks and Grit Removal Facilities, Calumet Water Reclamation Plant, to F.H. Paschen/S.N. Nielsen/IHC Construction, Joint Venture, in an amount not to exceed $228,474,000.00. The scheduled contract completion date is November 18, 2012.
As of April 20, 2012, the attached list of change orders has been approved. The effect of these change orders resulted in an increase in an amount of $4,796,347.30 from the original amount awarded of $228,474,000.00. The current contract value is $233,270,347.30. The prior approved change orders reflect a 2.10% increase to the original contract value.
Item 1: An extra in the amount of $63,337.23 to modify the Heating and Ventilating (HV) equipment platforms in the new Aerated Grit Building. OSHA standards require railings and toe-boards to be provided around all open sides of elevated platforms. The drawings for the HV unit equipment platforms in the new Aerated Grit Building do not include any railings or toe-boards. To ensure personnel safety and OSHA compliance, toe-boards and removable handrails should be installed along the perimeter of the five HV platforms. The contractor submitted a cost proposal (CCO-204) for an extra in the amount of $63,337.23. The engineer reviewed the proposal, found it to be reasonable, and stated via correspondence 2436, 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.
Item 2: An extra in the amount of $330,600.65 to install sheet piling to stabilize a portion of earthen dike between existing low solids Lagoons 7 and 8. During construction of the Primary Settling Tanks and Aerated Grit Facility, the excavated spoils were stockpiled in Lagoon 8. Upon removal of the spoils from the lagoon, part of the south wall of the earthen dike between Lagoon 7 and Lagoon 8 displaced and sloughed downwards. To repair and stabilize the dike, a 15-ft long sheet piling wall should be installed 2 feet north of the toe of the slope for the distance of the compromised slope. A layer of CA-1 stone backfill should be placed along the dike slope surface and the roadway on top of the dike should be restored. The contractor submitted a cost proposal (CCO-194) for an extra in the amount of $330,600.65. The engineer reviewed the proposal, found it to be reasonable and stated via correspondence 2435, 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 two change orders to increase Contract 07-220-3P in an amount of $393,937.88 (0.17% of the current contract value), from an amount of $233,270,347.30, to an amount not to exceed $233,664,285.18.
Funds are available in Account 401-50000-645650.
Requested, Kenneth A. Kits, Director of Engineering, TEK:ECB

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