This contract includes solid rock excavation in the tailrace of Bays 1 and 2 of the Lockport Powerhouse which is required for the construction of a new tailrace deck. The contract cost proposal F included 225 cubic yards of solid rock excavation and disposal off-site, estimated during design; however, the actual quantity of excavated rock was 315 cubic yards. The contractor submitted a cost proposal (COR-18) for the additional 90 cubic yards at the same unit price as in his original proposal. The engineer reviewed the proposal, found it to be reasonable, and stated via correspondence CO18, 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 15-830-3D in an amount of $22,500.00 (0.16% of the current contract value), from an amount of $13,759,511.82, to an amount not to exceed $13,782,011.82.
Funds are available in Account 401-50000-645720.
