While performing excavation work, the contractor notified the District that the amount of rock excavation needed for construction of the diversion channel was going to exceed the 3,300 cubic yards that were allocated for the project in Unit Price Item 4 in the contract. This increase in rock excavation is due to differing site conditions between the lower elevations of bedrock measured in the geo technical report and the higher elevations of bedrock encountered on site. In response to the higher bedrock elevation, the District issued a request for proposal to the contractor, modifying the cut and fill requirements of the diversion channel in order to reduce rock excavation quantities and requested a cost estimate for excess rock excavation quantities. The contractor submitted a cost proposal (COR-14) for an extra in the amount of $414,300.00 to excavate, sort, and stockpile an estimated 3,000 cubic yards of additional rock material. The engineer reviewed the proposal, found it to be reasonable, and recommends its approval. Payment made for this extra work will be based on actual quantity of rock excavation performed by the contractor.
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 14-253-AF in an amount of $414,300.00 (3.92% of the current contract value), from an amount of $10,581,167.46, to an amount not to exceed $10,995,467.46.
Funds are available in Account 501-50000-645620.
