Body
Dear Sir:
On June 15, 2023, the Board of Commissioners authorized the Director of Procurement and Materials Management to award Contract 06-360-3SR Upper Des Plaines Intercepting Sewer 14B Rehabilitation, NSA, to Michels Trenchless, Inc., in an amount not to exceed $36,082,848.50. The scheduled contract completion date is November 22, 2026.
As of August 14, 2026, the attached list of change orders has been approved.
Original Contract Amount $36,082,848.50
Date of Board Approval 6/15/2023
Cumulative Change Order (8/14/2026) $1,485,855.78
% Change of Original Contract Value 4.12%
Current Contract Value $37,568,704.28
Requested Increase $106,774.14
New Contract Value $37,675,478.42
% Change of Current Contract Value 0.28%
Total % Change of Original Contract Value 4.41%
The purpose of Contract 06-360-3SR is to rehabilitate 2,888 feet of 48-inch diameter sewer, 11,908 feet of 69-inch diameter sewer, 28 manholes/structures, the safe abandonment of one offset manhole, part of a control structure, and 85 feet of 3’-6” x 4’-6” pipe.
During sewer cleaning operations from Sta. 114+14 to Sta. 137+24, the contractor encountered unforeseen conditions that required substantially more effort than anticipated to properly clean and prepare the pipe surface for lining. In addition to removing normal sewer debris, extensive pressure washing was needed to remove deteriorated concrete in the existing sewer to a depth sufficient to reach structurally sound material. This resulted in an additional 12 days of cleaning work.
An extra in the amount of $156,830.89 was previously approved by the Board of Commissioners on March 19, 2026, under CO-15 to address the extended cleaning effort. However, bypass-related costs were not included in that approval. The current change order seeks reimbursement for bypass costs directly associated with the additional cleaning operations, including bypass rental, maintenance/pump watch, and fuel required to operate the bypass system during the 12-day period in which the contractor performed only the cleaning work approved under CO-15, with no other contractually obligated work occurring.
The contractor submitted a cost proposal (CO-27), dated August 7, 2026, requesting an “extra” in the amount of $106,774.14 and a “credit” in the amount of $0.00, for a “net extra” in the amount of $106,774.14. The engineer reviewed the proposal, found it acceptable and stated via correspondence CO27 that the Engineering Department would recommend its approval.
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 06-360-3SR, in an amount of $106,774.14 (0.28% of the current contract value), from an amount of $37,568,704.28, to an amount not to exceed $37,675,478,42.
Funds are available in Account 401-50000-645700.
Requested, Catherine A. O’Connor, Director of Engineering, KMF:LS
Recommended, Darlene A. LoCascio, Director of Procurement and Materials Management
Respectfully Submitted, Precious Brady-Davis, Chairperson Committee on Procurement
Disposition of this agenda item will be documented in the official Regular Board Meeting Minutes of the Board of Commissioners for September 3, 2026
