Body
Dear Sir:
On March 20, 2008, the Board of Commissioners authorized the Director of Procurement and Materials Management to award Contract 05-144-3D Lagoon 23 Lining & Lysimeters Installation, LASMA, HASMA & CWRP to T. J. Lambrecht Construction, Inc., in an amount not to exceed $10,096,671.91. The scheduled contract completion date was April 8, 2009.
As of April 6, 2010, the attached list of change orders has been approved. The effects of these change orders resulted in an increase in the amount of $1,312,801.05 from the original amount awarded of $10,096,671.91. The current value is $11,409,472.96. The prior approved change orders reflect a 13% increase to the original contract value.
This was a claim submitted by the contractor for additional compensation per Article 5, 7 and 8 of the General Conditions. The additional costs were caused by delays due to unknown subsurface conditions that were encountered. The unsuitable soil was adjacent to a Commonwealth Edison Transmission Tower which required a design solution. The design effort extended the project into the winter months when no earthwork could be performed and the contractor had to preserve the work completed to date by continuous pumping of the lagoon. The change order amount of $69,434.17 includes the labor wage rate difference between construction seasons, continuous pumping of lagoon 23 and equipment use and insurance premiums as allowed by the contract.
The contractor submitted an extra work in the amount of $69,434.17. The engineer reviewed the proposal, found it reasonable, and stated via correspondence 246, 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 that were 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 05-144-3D in an amount of $69,434.17 (0.61% of the current contract value) from an amount of $11,409,472.96 to an amount not to exceed $11,478,907.13.
Funds are available in Accounts 401-50000-645650 and 645750.
Requested, Kenneth A. Kits, Acting Director of Engineering, RL:BS
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 May 6, 2010
