About this file

This is a Change Order Notice issued by the Chief Procurement Office for General Services for the Illinois Department of Natural Resources (DNR) regarding the Carlyle Lake Riverside Embankment Stabilization project at three locations along the Kaskaskia River. The original project scope involved armor installation on three eroded levee sections. The change order authorizes the addition of 2,000 tons of IDOT size RR5 riprap stone to supplement one section that experienced significant additional erosion during spring and summer 2026 flood events, effectively doubling the riprap stone requirements for that particular area. The contractor has equipment already positioned on site and is prepared to execute the additional work immediately upon authorization. This change order meets the posting requirement threshold as it increases contract cost by more than $25,000 and is being posted on the Bulletin/BidBuy for the mandatory 14-day review period.

The change order documents that the additional erosion and corresponding material requirements were not reasonably foreseeable at the time of the original contract award, satisfying the statutory criteria for change order justification under Section 33E-9 of the Criminal Code. The circumstances necessitating this change are directly germane to the original contract scope and project objectives. The referenced procurement identification number is BBREFNO 26-422DNR-REALT-P-99967.

thedetails: The original project is to armor three sections of levee located along the Kaskaskia River that have been gradually eroded by the river over time. After the project was awarded, a portion of one of the sections experienced significant additional erosion during spring and summer 2026 flood events which roughly doubles the amount of riprap stone needed to stabilize and protect that area. The addition of 2000 tons of IDOT size RR5 riprap stone is required to supplement the section that experienced the additional erosion. The original project cannot be completed without the additional stone. The contractor has the equipment on site to do the additional immediately upon authorization.
