To address odor concerns at the Thornton Composite Reservoir, an odor control misting system is currently being constructed under this contract. The system includes the installation of a PVC coated flexible odor control duct along the North and East perimeter of the Thornton Composite Reservoir. The Contractor discovered that approximately 130 feet of the installed flexible duct had been torn from its mounts and damaged, presumably due to high wind. The manufacturer recommended that the damaged flexible duct undergo repairs and installation of additional grommets to secure the duct to the fence and reduce the likelihood of damage due to wind. In addition, the remaining undamaged 3,970 feet of flexible duct will also be improved by installing additional grommets by the manufacturer to avoid future damage. This change order includes an extra for repairs, improvements, and the additional material and labor to install the flexible duct. The contractor submitted a cost proposal (CO-24) for an extra in the amount of $24,006.40. The Engineer reviewed the proposal, found it to be reasonable, and stated via correspondence CO24 that the Engineering Department would recommend its approval.
This change order is in compliance with the Illinois Criminal Code since the changes are due to circumstances not reasonably foreseeable at the time the contract was signed and are 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 15-266-4H5 in an amount of $24,006.40 (0.09% of the current contract value), from an amount of $26,092,698.66, to an amount not to exceed $26,116,705.06.
Funds are available in Account 401-50000-645620.

Respectfully Submitted, Marcelino Garcia, Chairman Committee on Procurement
