Title
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 $321,566.44, from an amount of $3,226,745.33, to an amount not to exceed $3,548,311.77, Account 401-50000-645600, Purchase Order 4000072 (Deferred from the January 21, 2021 Board Meeting)
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 February 17, 2021.
As of January 8, 2021, the attached list of change orders has been approved. The effect of these change orders resulted in an increase in an amount of $229,745.33 from the original amount awarded of $2,997,000.00. The current contract value is $3,226,745.33. The prior approved change orders reflect a 7.67% increase to the original contract value.
On July 2, 2020, the Maintenance & Operations Department discovered that the existing louver system at construction shaft CS-N2 in Morton Grove was damaged during a storm event. A site investigation was completed, and it appears a hydraulic transient surge event occurred at the subject location and damaged the existing louver system beyond repair. After review, it was recommended to remove the entire damaged louver system as it is structurally unstable and may collapse into the deep tunnel system. IHC Construction Companies is currently under contract installing louver systems at various dropshaft locations and as such has the equipment and construction know-how to remove the subject louver system. Due to these conditions, it is recommended to remove the damaged louver system and conduct subsequent concrete shaft repair work at CS-N2. This change will allow additional air flow through the construction shaft and will decrease the likelihood of damage in the future. The contractor submitted a cost proposal (CO10) for an extra in the amount of $321,566.44. The engineer reviewed the proposal, found it to be reasonable, and stated via correspondence CO10, 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 $321,566.44 (9.97% of the current contract value), from an amount of $3,226,745.33, to an amount not to exceed $3,548,311.77.
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 February 4, 2021
