Body
Dear Sir:
On December 2, 2010, the Board of Commissioners authorized the Director of Procurement and Materials Management to award Contract 04-203-4F Final Reservoir Preparation, Thornton Composite Reservoir, Calumet Service Area, to Walsh/II in One, Joint Venture, in an amount not to exceed $50,763,937.00. The scheduled contract completion date is November 1, 2015.
As of May 22, 2015, the attached list of change orders has been approved. The effect of these change orders resulted in an increase in an amount of $166,184.31 from the original amount awarded of $50,763,937.00. The current contract value is $50,930,121.31. The prior approved change orders reflect a 0.33% increase to the original contract value.
The Thornton Composite Reservoir is scheduled to be operational later this year. To address concerns of potential odors to surrounding communities from the open-air reservoir, seven solar aerators will be used to minimize odor escape by maintaining a stable, aerobic layer at the water surface. The aerators are being furnished and installed under a separate contract. However, concrete mooring blocks are needed on the floor of the reservoir to anchor the aerators. Each aerator requires connection to an individual concrete mooring block. Seven concrete blocks with 3-ft x 3-ft x 1-ft dimensions and reinforced with stainless steel rebar will be constructed and placed under this change order. The contractor submitted a cost proposal (CCO-016) for an extra in the amount of $11,121.24. The engineer reviewed the proposal, found it to be reasonable, and stated via correspondence 615, that the Engineering Department would recommend its approval.
This change order is in compliance with the Illinois Criminal Code since the change is germane to the contract.
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 04-203-4F in an amount of $11,121.24 (0.02% of the current contract value), from an amount of $50,930,121.31, to an amount not to exceed $50,941,242.55.
Funds are available in Account 401-50000-645600.
Requested, Catherine A. O'Connor, Director of Engineering, WSS:KMF
Recommended, Darlene A. LoCascio, Director of Procurement and Materials Management
Respectfully Submitted, Barbara J. McGowan, Chairman Committee on Procurement
