Body
Dear Sir:
On September 5, 2019, the Board of Commissioners authorized the Director of Procurement and Materials Management to award Contract 17-134-3MR (Re-Bid) Odor Control Facilities at Sludge Concentration, Southwest Coarse Screen, Overhead Weir, and Post-Centrifuge Building, Stickney Water Reclamation Plant, to IHC Construction Companies, L.L.C., in an amount not to exceed $16,485,000.00, plus a five (5) percent allowance for change orders in an amount of $824,250.00, for a total amount not to exceed $17,309,250.00. The scheduled contract completion date is August 3, 2021.
As of April 16, 2021, the attached list of change orders has been approved. The effect of these change orders resulted in an increase in the amount of $50,331.63 from the original amount awarded of $16,485,000.00. The current contract value is $16,535,331.63. The prior approved change orders reflect a 0.31% increase to the original contract value.
An extra is requested to furnish all labor required to perform graphic changes, programming, Distributed Control System (DCS) commissioning, DCS start-up testing work and confirming that all the DCS input and output points are effectively incorporated into the programming. The contract was designed and awarded with the provisions that District process control engineers would perform this work. After the contract was awarded and under construction, it became clear that this work is time sensitive and is most efficient to have the work proceed with the oversight and coordination of the General Contractor. Therefore, revisions are necessary to provide an extra for DCS programming to allow communication and control of the new odor control facilities. The contractor submitted a cost proposal (CO-9) for an extra in the amount of $243,078.00. The engineer reviewed the proposal, found it reasonable, and stated via correspondence C009, 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 17-134-3MR (Re-Bid) in an amount of $243,078.00 (1.47% of the current contract value), from an amount of $16,535,331.63, to an amount not to exceed $16,778,409.63.
Funds are available in Account 401-50000-645650.
Requested, Catherine A. O’Connor, Director of Engineering, ECB, GR
Recommended, Darlene A. LoCascio, Director of Procurement and Materials Management
Respectfully Submitted, Barbara J. McGowan, Chairman Committee on Procurement
