Authority to increase Contract 01-353-2M Rehabilitation of the Existing Influent Pumping Station at Kirie Water Reclamation Plant, to Rausch Construction Company in an amount of $16,708.38, from an amount of $21,926,306.83, to an amount not to exceed $21,943,015.21, Accounts 401-50000-645650 and 645750, Purchase Order 5000394.
Body
Dear Sir:
On May 5, 2005, the Board of Commissioners authorized the Director of Procurement and Materials Management to award Contract 01-353-2M, Rehabilitation of the Existing Influent Pumping Station at Kirie Water Reclamation Plant, to Rausch Construction Company, in an amount not to exceed $20,896,800.00. The scheduled contract completion date was April 18, 2008.
As of April 20, 2012, the attached list of change orders has been approved. The effect of these change orders resulted in an increase in the amount of $1,029,506.83 from the original amount awarded of $20,896,800.00. The current contract value is $21,926,306.83. The prior approved change orders reflect a 4.93% increase to the original contract value.
The contract includes replacement of the six pumping systems with related components (piping, suction and discharge valves, etc.) at the Kirie Water Reclamation Plant. The contract documents listed the average wet well low level as -81.00 (providing 19' of head on the knife gate valve at the pump level). However, after Pump No. 4 was completed, it was determined that in the event of an emergency, there is the potential of the wet well filling up to the ground level, approximate elevation +79.00' (resulting in 179' of head on the knife gate valve at the pump level). Because of this potential, additional temporary restraints have to be installed for the existing gate valves while the pumps are removed. This change order is for the remaining five (5) pumping systems. The contractor submitted a cost proposal (CCO-59) for an extra in the amount of $19,397.40 to complete the work. Subsequent negotiations with the contractor failed to reach an agreeable solution. Consequently, the engineer determined the value of the above mentioned extra to be $16,708.38 and issued file letter 902, which states that the engineer is exercising his power to make final and binding determination under Article 8 of the General Conditions concerning this work, and that he would recommend approval as an extra in the amount of $16,708.38 to the Board of Commissioners.
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 01-353-2M in an amount of $16,708.38 (0.08% of the current contract value), from an amount of $21,926,306.83, to an amount not to exceed $21,943,015.21.
Funds are available in Accounts 401-50000-645650 and 645750.
Requested, Kenneth A. Kits, Director of Engineering, TEK:JAW
Recommended, Darlene A. LoCascio, Director of Procurement and Materials Management
Respectfully Submitted, Barbara J. McGowan, Chairman Committee on Procurement
