Authority to increase Contract 17-842-3H Modifications to TARP Control Structures & Drop Shafts, SSA and CSA to IHC Construction Companies, Inc.in an amount of $139,075.48, from an amount of $3,087,669.85, to an amount not to exceed $3,226,745.33, Account 401-50000-645600, Purchase Order 4000072
Body
Dear Sir:
On September 19, 2019, the Board of Commissioners authorized the Director of Procurement and Materials Management to award Contract 17-842-3H Modifications to TARP Control Structures & Drop Shafts, SSA and CSA, in an amount not to exceed $2,997,000.00. The scheduled contract completion date is December 25, 2020.
As of November 20, 2020, the attached list of change orders has been approved. The effect of these change orders resulted in an increase in an amount of $90,669.85 from the original amount awarded of $2,997,000.00. The current contract value is $3,087,669.85. The prior approved change order reflects a 3.03% increase to the original contract value.
The contractor, per the plans and specifications, was required to install louvers for odor control at existing drop shaft DS-M27. The contractor was also required to install a new grating at grade level to match the existing dropshaft structure elevations. However, upon inspection, DS-M27 is located on property currently owned by a scrap metal yard where metals and other materials have been stockpiled in close proximity to the dropshaft and can easily be washed into the shaft. Furthermore, the grade elevation of the property has been increased over time and drains toward the dropshaft. Due to these field conditions, it is recommended to raise dropshaft DS-M27 6-feet from grade level in order to prevent surface water and surrounding debris from falling onto the louvers and/or entering the deep tunnel system. The contractor submitted a cost proposal (CO-11) for an extra in the amount of $139,075.48. The engineer reviewed the proposal, found it to be reasonable, and stated via correspondence CO11, 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 17-842-3H in an amount of $139,075.48 (4.50% of the current contract value), from an amount of $3,087,669.85, to an amount not to exceed $3,226,745.33.
Funds are available in Account 401-50000-645600.
Requested, Catherine A. O’Connor, Director of Engineering, KMF
Recommended, Darlene A. LoCascio, Director of Procurement and Materials Management
Respectfully Submitted, Barbara J. McGowan, Chairman Committee on Procurement
Disposition of this agenda item will be documented in the official Regular Board Meeting Minutes of the Board of Commissioners for December 3, 2020
