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 March 16, 2012, the attached list of change orders has been approved. The effect of these change orders resulted in an increase in an amount of $4,680,003.13 from the original amount awarded of $228,474,000.00. The current contract value is $233,154,003.13. The prior approved change orders reflect a 2.05% increase to the original contract value.
Additional work is required to replace expansion joint filler material in the service tunnels. The contract calls for expansion joints with water stops at the bottom slab of the service tunnels at approximately 100 foot intervals. Due to the need to correct a hydraulic condition before start-up, the conduits below the tunnel sat empty throughout the winter. The lower temperatures caused the concrete to contract slightly, thus causing the joint filler material to separate from the expansion joint. Upon filling the conduits during start-up, water seeped into the service tunnel above the conduits through the compromised expansion joint filler material. Therefore, at ten service tunnel expansion joint locations, installed filler material needs to be removed, the joint surfaces need to be cleaned and new filler material with hydrophilic grout needs to be installed. The contractor submitted a cost proposal (CCO-203) for an extra in the amount of $96,269.20. The engineer reviewed the proposal, found it to be reasonable, and stated via correspondence 2421, 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 increase Contract 07-220-3P in an amount of $96,269.20 (0.04% of the current contract value), from an amount of $233,154,003.13, to an amount not to exceed $233,250,272.33.
Funds are available in Account 401-50000-645650.
Requested, Kenneth A. Kits, Director of Engineering, TEK:ECB
Recommended, Darlene A. LoCascio, Director of Procurement and Materials Management
Respectfully Submitted, Barbara J. McGowan, Chairman Committee on Procurement
Disposition of this agenda item will be documented in the official Regular Board Meeting Minutes of the Board of Commissioners for April 5, 2012
