The engineer determined the amount of material required to be removed from the channels and aeration tanks to perform contract work will exceed the quantities estimated in the contract documents by approximately 550 cubic yards. The contractor submitted a cost proposal (CO-02) for all labor, supervision, tools, and equipment for this work for an extra in the amount of $440,000.00 and a credit in the amount of $0.00, for a net extra in the amount of $440,000.00. Subsequent to receiving the contractor’s cost proposal, it was discovered that additional material would be required to be removed from Battery A channels during the battery shutdowns and that the previous estimate was too low. The estimate for the total additional material to be removed was revised to 1,400 cubic yards and a counterproposal for an amount not to exceed $1,120,000.00 was issued and accepted by the contractor. It was stated via correspondence CO02 that the Engineering Department would recommend its approval.
The above change order is in compliance with the Illinois Criminal Code since the change is germane to the contract as signed.
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 08-174-3D in an amount of $1,120,000.00 (1.98% of the current contract value), from an amount of $56,449,000.00, to an amount not to exceed $57,569,000.00.
Funds are available in Account 401-50000-645750.
