The Engineer has determined that certain revisions are required to the original scope of work for replacing a total of twenty-four control stations and motorized actuator components for the Digester Feed and Draw Valves in each of the three Digester Chambers A, B, and C in order to allow for compliance with a hazardous classified area installation. The revisions are necessary since the replacement of the control station and actuators were not shown correctly to be explosion proof rated for all three Digester Chambers under the subject contract. The contractor submitted cost proposal (CO-20) for an extra in the amount of $344,965.56 and a credit in the amount of $16,785.12, for a net extra in the amount of $328,180.44. The Engineer reviewed the proposal, found it to be reasonable, and stated via correspondence CO20, 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 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 18-148-3P in an amount of $328,180.44 (0.62% of the current contract value), from an amount of $52,823,481.22, to an amount not to exceed $53,151,661.66.
Funds are available in Account 401-50000-645750
