This contract includes the installation of new stop logs in Bays 1 and 2 of the Lockport Powerhouse. During construction, it was discovered that the new stop logs, as designed by the manufacturer, did not fit through the existing stop log openings and could not be lowered into the channels to isolate the bays and allow dewatering. For the work to proceed, the contractor was directed to enlarge the openings; an Request for Proposal (RFP ) was issued for the work already performed and additional work to protect the deck by installing a concrete beam at the cut edge and performing concrete repairs at the opposite edge. The contractor submitted a cost proposal (COR-17) for an extra in an amount of $330,571.86. The engineer reviewed the proposal and submitted a counterproposal for an amount of $327,758.26, which was accepted by the contractor, and stated via correspondence CO17, that the Engineering Department would recommend its approval.
This change order is in compliance with the Illinois Criminal Code since the change is germane to the contract.
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 $327,758.26 (2.38% of the current contract value), from an amount of $13,782,011.82, to an amount not to exceed $14,109,770.08.
Funds are available in Account 401-50000-645720.
