TRANSMITTAL LETTER FOR BOARD MEETING OF SEPTEMBER 17, 2020
COMMITTEE ON PROCUREMENT
Mr. Brian A. Perkovich, Executive Director
Title
Authorization to amend Contract 18-277-3M Digester Sludge Heating System Upgrades and Boiler Removal, Calumet Water Reclamation Plant, to IHC Construction Companies, LLC, Account 401-50000-645750, Purchase Order 4000074
Body
Dear Sir:
On December 19, 2019, the Board of Commissioners authorized the Director of Procurement and Materials Management to award contract 18-277-3M Digester Sludge Heating System Upgrades and Boiler Removal, Calumet Water Reclamation Plant, to IHC Construction Companies, LLC in an amount not to exceed $25,499,000.00. The scheduled contract completion date is January 19, 2023.
As of August 26, 2020, the attached list of change orders has been approved. The effect of these change orders resulted in a net increase in the amount of $68,643.38 from the original amount awarded of $25,499,000.00. The current contract value is $25,567,643.38. The prior approved change orders reflect a 0.27% increase to the original contract value.
The contract includes work for emptying and cleaning the digesters. The original contract included Cost Proposal L, a unit price of $85.00 per cubic yard, to remove, transport, and legally dispose off-site all sludge, grit, sediments and other contents within the digester above elevation -0.50 CCD. Removal of material below elevation -0.50 CCD is part of the lump sum contract work. An addendum to the original contract gave the contractor an option of pumping the remaining contents of the digester below elevation -0.50 CCD to the headworks of the plant instead of pumping and legally transporting and disposing off site of the remaining contents; however, the addendum did not address this change with respect to the unit price in Cost Proposal L. Since the contractor chose to remove the contents above elevation -0.50 CCD by pumping to the headworks of the plant, an amendment to the contract is required to adjust the unit price. The District and contractor have agreed to a price of $47.36 per cubic yard for the work required to remove and pump to headworks any contents above the elevation of -0.50 CCD, contingent upon approval by the Board of Commissioners.
The above amendment is in compliance with the Illinois Criminal Code since the amendment is germane to the contract.
It is hereby recommended that the Board of Commissioners authorize the Director of Procurement and Materials Management to amend the unit price on Contract 18-277-3M resulting in a no change to the current contract value of $25,567,643.38.
Requested, Catherine 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
Disposition of this agenda item will be documented in the official Regular Board Meeting Minutes of the Board of Commissioners for September 3, 2020
