TRANSMITTAL LETTER FOR THE BOARD MEETING OF JULY 10, 2014
COMMITTEE ON PROCUREMENT
Mr. David St. Pierre, Executive Director
Title
Authority to increase Contract 14-213-EW Emergency Work Repairing and Improving Junction Chamber Associated with Calumet TARP, Little Calumet Leg, to Jay Dee Contractors in an amount of $250,000.00, from an amount of $250,000.00, to an amount not to exceed $500,000.00, Account 901-50000-667220, Purchase Order 3081415
Body
Dear Sir:
On May 15, 2014, the Board of Commissioners authorized the execution of an emergency contract to repair and improve connecting structures associated with Calumet TARP Drop Shaft CDS-55 due to damage that occurred from the storm of May 11, 2014. Contract 14-213-EW was executed with Jay Dee Contractors in an amount not to exceed $250,000.00.
As of June 20, 2014, there have been no change orders on this contract.
During the storm of May 11, 2014, approximately 1.8 inches of rain fell in one hour on the south side. At approximately 8:00 pm that night, a concrete slab buried 10 feet beneath the ground was blown off the roof of the junction structure, along with much of the earth above it. In addition the manhole grating was blown off its location. The surrounding fill was washed into the chamber through the hole where the concrete slab had been, resulting in a large sinkhole surrounding the junction chamber. Less severe damage was noted at various other structures on the Calumet TARP Little Calumet Leg that would also require repairs.
Upon entering the structure, the Contractor discovered that the fill material believed to be washed down the system had actually accumulated throughout the sewer, preventing the contractor from gaining access and making dewatering efforts very difficult. The accumulated material had to be removed from the sewer prior to starting the repair work. Additionally, the initial proposal did not include work at the various additional structures that were found damaged. It is estimated that the additional work associated with the removal of the fill material, as well as the additional work at the various other structures, will bring the total cost of emergency work to $500,000.00.
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 14-213-EW in an amount of $250,000.00 (100% of the current contract value), from an amount of $250,000.00, to an amount not to exceed $500,000.00.
Funds are available in Account 901-50000-667220.
Requested, Catherine A. O'Connor, Director of Engineering, WSS:KMF
Recommended, Darlene A. LoCascio, Director of Procurement and Materials Management
Respectfully Submitted, Barbara J. McGowan, Chairman Committee on Procurement
