CHANGE ORDER NOTICE: DNR Carlyle Lake- Stabilize Riverside Embankment (3 locations)

The Illinois Department of Natural Resources is posting a change order notice through the Chief Procurement Office for General Services, with review due November 24, 2026, to add 2,000 tons of IDOT size RR5 riprap stone and extend time on the Carlyle Lake Riverside Embankment Stabilization project at three locations along the Kaskaskia River. The Chief Procurement Office for General Services is acting on behalf of DNR.

The original scope called for armor installation on three eroded levee sections. The change responds to significant additional erosion during spring and summer 2026 flood events at one section, effectively doubling the riprap requirement for that area. The notice increases contract cost by more than $25,000 and extends the contract time. The incumbent contractor already has equipment positioned on site and will execute the added work immediately upon authorization.

The notice states that the additional erosion and corresponding material needs were not reasonably foreseeable at original award, citing Section 33E-9 of the Criminal Code as the change-order justification, and that the work is directly germane to the original contract scope. It is posted on Bulletin/BidBuy for a mandatory 14-day review period. The procurement identification number is BBREFNO 26-422DNR-REALT-P-99967, and the notice was posted November 9, 2026.
