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 plus a five percent allowance for change orders in an amount of $1,804,142.42, for a total amount not to exceed $37,886,990.92.

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, and 28 manholes/structures, and to safely abandon 1 offset manhole, part of a control structure, and 85 feet of 3’-6” x 4’-6” pipe.
The contractor has raised concerns regarding the safety and soundness of the manhole structure at Sta. 137+24, noting significant deterioration of the concrete by sulfate attack. As a result, the contractor indicated that additional time and site preparatory work will be required to restore this manhole structure to a condition suitable for the contract-specified rehabilitation work to be performed. The contractor submitted an extra for two items.
Item 1 (Lump Sum Payment): The contract specified the structural rehabilitation of the existing manhole structure at Sta. 137+24 from ground surface to sewer invert, utilizing a carbon fiber reinforced polymer lining system. The contractor’s proposed lump-sum price accounts for all additional labor, equipment, and subcontractor expenses necessary to remove deteriorated concrete and restore the manhole structure to the appropriate condition for the contract-specified work to be performed. This lump sum does not include any bypass-related expenses.
Item 2 (Not-to-Exceed Payment): To perform Item 1 work, the manhole at Sta. 137+24 must remain fully isolated from active flow. Although the contract requires the contractor to provide bypass pumping during rehabilitation, additional preparation time is necessary, resulting in bypass costs beyond the original scope. The District and the contractor agreed to a not-to-exceed amount based on 56 days of operational bypass and 16 days of non-operational bypass. The District will compensate the contractor based on the actual days spent performing bypass work related to the change order.
The contractor submitted a cost proposal (CO-26) requesting an extra for Item 1 work in the lump-sum amount of $438,346.06, and an extra for Item 2 work in a not-to-exceed amount on a time and materials basis of $510,247.94, and a “credit” in the amount of $0.00, for a “net extra” in the amount of $948,594.00. The engineer reviewed the proposal, found it to be reasonable, and stated via correspondence CO26, that the Engineering Department will 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 $948,594.00 (2.60% of the current contract value), from an amount of $36,517,025.05, to an amount not to exceed $37,465,619.05.
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
