A portion of the project’s scope included installation of a new boardwalk to facilitate pedestrian access across Buffalo Creek Main Stem. To help stabilize this reach of Buffalo Creek, banks were cleared and a series of riffle structures were installed to help facilitate flows. Shortly after completion of this work, it was observed that a portion of the creek had shifted and was eroding near the piles of the Main Stem boardwalk. As a preemptive measure to limit further erosion and maintain integrity of the Main Stem boardwalk, the District is recommending installation of two riprap trenches to minimize creek downcutting near the boardwalk piles, as well as lining the creek banks with riprap at this location. An existing riffle structure will be adjusted to direct flows toward the center of the channel. On December 2, 2021, the contractor submitted cost proposal (COR-08) for an extra in an amount of $126,070.00. The engineer reviewed the proposal for the work described above, and while the engineer and contractor were unable to come to an agreement regarding the cost, in an effort to expedite the work, the Engineering Department is recommending approval to the Board of Commissioners. This work will be tracked and paid on a time and materials basis not to exceed the contractor’s proposed amount.
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 13-370-3F in an amount not to exceed $126,070.00 (1.30 percent of the current contract value), from an amount of $9,676,606.85, to an amount not to exceed $9,802,676.85.
Funds are available in Account 401-50000-645620.
