Title
Joint committee action approving Change Order Number One with Chicagoland Trenchless Rehabilitation Inc. of Niles, Illinois for unforeseen sewer conditions resulting in a cost increase.
Staff Summary
* On June 14, 2022, the Lake County Board authorized a contract with Chicagoland Trenchless Rehabilitation Inc. to install the water main quality sewer liner in the Park West Townhome Subdivision as a condition of the permit issued by the Illinois Environmental Protection Agency (IEPA).
* Change Order Number One is a result of storm sewers that were submerged in floodwater, requiring dewatering, additional joints that were found, requiring spot lining over the joints, and a sewer pipe diameter that was found to be larger than anticipated. Responding to the identified conditions requires a price adjustment with an increased cost of $36,100 for the project.
* In accordance with Article 8, section 101(2) of the Lake County Purchasing Ordinance, the change order was not reasonably foreseeable at the time the contract was signed.
* Change Order Number One accounts for dewatering the sewer pipes, installing additional liners for the joints, and price adjustment for the larger size of the sewer pipe, resulting in an increased cost of $36,100 from $109,999 to $146,099 for the project.
