Change Order Notice_2305 Buwick Change Order #1

The Illinois Department of Natural Resources, through its Chief Procurement Office for General Services, has issued a change order to Contract P-94823 for abandoned mined lands remediation services at Old Man Lake northeast of Cuba, Illinois, with a 14-day review period closing October 12, 2026.

This is a change order increasing scope and cost on an existing contract. The modification revises specifications for Structure No. 1 at the primary lake outlet, replacing the originally specified precast concrete structure with a larger precast box structure and changing the inlet pipe from concrete to ductile iron with extended length. The project is part of federally funded AML remediation work under the U.S. Department of the Interior, Office of Surface Mining, to eliminate mine-related public health and safety hazards.

The change order increases contract costs by more than $25,000, triggering the statutory 14-day posting requirement on the Bulletin/BidBuy prior to implementation. The modifications are characterized as germane to the original contract and address construction and operational needs identified post-execution.
