To address odor concerns at the Thornton Composite Reservoir, an odor control misting system is currently being constructed under this contract. During construction, the contractor encountered rock and unsuitable soils for the installation of the electrical grounding system and could not achieve required resistance values. After further investigation, it was determined that the contractor will need to core a hole into the bedrock and install a new copper clad ground rod. The cored hole will be backfilled with conductive concrete and the site restored back to original condition. This change order includes an extra for the improvements, and the additional material and labor to install the grounding system. The contractor submitted a cost proposal (CO-25) for an extra in the amount of $16,929.86 and a credit in the amount of $0,00, for a net extra in the amount of $16,929.86. The engineer reviewed the proposal, found it to be reasonable, and stated via correspondence CO25 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 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 $16,929.86 (0.06% of the current contract value), from an amount of $26,116,705.06, to an amount not to exceed $26,133,634.92.
Funds are available in Account 401-50000-645620.
