This contract includes the replacement of large diameter pipe couplings, upstream and downstream of Main Sewage Pumps Nos. 1, 3 and 5, as part of the rehabilitation work being performed under this contract. The contractor proposed an alternative style coupling to be used on the Pump No. 3 suction piping because field measurements showed that the offset between the wall flange associated with Pump No. 3 and the suction valve upstream of Pump No. 3 was not within the manufacturer’s recommended tolerances for the original style of coupling specified. The contractor submitted a cost proposal (CO-14) for an extra in the amount of $117,045.59 and a credit in the amount of $5,535.75, for a net extra in the amount of $111,509.84. The engineer reviewed the proposal, found it to be reasonable and stated, via correspondence CO14, that the Engineering Department would recommend its approval.
This change order is in compliance with the Illinois Criminal Code since it 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 18-144-3M in an amount of $111,509.84 (0.47% of the current contract value), from an amount of $23,608,797.42, to an amount not to exceed $23,720,307.26.
Funds are available in Account 401-50000-645700.
