The purpose of Contract 10-047-3S is to rehabilitate a 10,108 foot-long, 6' x 9’ sewer, a 4,264 foot-long, 6' x 8' sewer, a 520 foot-long, 15” sewer, and 23 manhole structures in Kenilworth, Wilmette, and Winnetka, as well as to construct three manholes on the Evanston Intercepting Sewer No. 1, and modify one TARP drop shaft (DS-M105E) in Evanston.
The original contract scope included sewer cleaning work to remove and dispose of all internal solids and debris from the sewer in a lawful manner. However, due to concerns with the sewer solids being characterized as hazardous, additional handling and waste characterization testing requirements not reasonably foreseeable prior to bid are required to ensure the lawful disposal of the debris. The revisions to the contract require the contractor to adhere to these additional handling and waste characterization testing requirements for the duration of the contract. As such, the subject change order is for handling and waste characterization testing between the North Shore 1 intercepting sewer stations 0+00 to 101+08. A subsequent change order for handling and waste characterization testing for collected waste will be necessary for the last half of the intercepting sewers from station 101+08 to 144+00, and will be presented to the Board at a later date. This work is being processed in two phases, in the interest of not delaying work under the subject contract. It is also anticipated that additional change orders will be necessary for the handling and disposal of hazardous waste, if discovered in the waste characterization of the debris. The contractor submitted a cost proposal (CO-04) for this work as an extra in the amount of $433,264.07 and a credit in the amount of $0.00, for a net extra in the amount of $433,264.07. The Engineer reviewed the proposal, found it to be reasonable, and stated via correspondence CO04, that the Engineering Department will recommend its approval to the Board of Commissioners.
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 10-047-3S, in an amount of $433,264.07 (0.96% of the current contract value), from an amount of $44,990,757.04, to an amount not to exceed $45,424,021.11.
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, Marcelino Garcia, Chairman Committee on Procurement
