Body
Dear Sir:
On April 7, 2022, the Board of Commissioners authorized the Director of Procurement and Materials Management to award Contract 15-069-3D, Rehabilitation of Steel Spandrel Beams of Pump and Blower House, O’Brien Water Reclamation Plant, to IHC Construction Companies, LLC, in an amount not to exceed $21,730,00.00, plus a five (5) percent allowance for change orders in an amount of $1,086,500.00, for a total amount not to exceed $22,816,500.00. The scheduled contract completion date is May 2, 2025.
As of July 12, 2024, the attached list of change orders has been approved.
Original Contract Amount $21,730,000.00
Date of Board Approval 4/7/2022
Cumulative Change Order (7/12/2024) $94,317.98
% Change of Original Contract Value 0.43%
Current Contract Value $21,824,317.98

An extra in the amount of $108,603.75 is required to provide additional structural reinforcement of roof spandrel beams along the south wall of the O’Brien Pump and Blower House. This contract includes removal of masonry and stone along the perimeter of the Pump and Blower House to expose the existing structural steel framing and reinforce beams, columns, and connections which have lost capacity due to corrosion. However, during construction, it was discovered that some steel roof spandrels along the east and west walls had considerably more section loss than anticipated and required additional steel reinforcement. The additional repairs along the east and west walls, and chimney repairs, were performed under Cost Proposal B, a $550,000.00 allowance item for performing unanticipated structural repairs. To date, a total of $373,364.45 has been committed for expenditure under Cost Proposal B, leaving a balance of $176,635.55 available to complete additional work.
Based on the deterioration observed thus far and the likelihood of identifying more deterioration as work continues, approval of an additional $391,396.25 is requested to perform additional repairs on a T&M basis along the north wall and tower areas where contract work has not been initiated. Authorization of the additional funds will minimize construction delays and prevent accrual of significant idle equipment charges for mobile platforms which are on-site to perform work.
The above two change orders are in compliance with the Illinois Criminal Code since the changes are due to circumstances not reasonably foreseeable at the time the contract was signed and are 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 15-069-3D in an amount of $500,000.00 (2.29% of the current contract value), from an amount of $21,824,317.98, to an amount not to exceed $22,324,317.98.
Funds are available in Account 401-50000-645780.
Requested, Catherine A. O’Connor, Director of Engineering, GMR:GRR:VP
Recommended, Darlene A. LoCascio, Director of Procurement and Materials Management
Respectfully Submitted, Marcelino Garcia, Chairman Committee on Procurement
