Title
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 $167,701.05, from an amount of $21,345,063.62 to an amount not to exceed $21,512,764.67, 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, to Rausch Construction Company, in an amount not to exceed $20,896,800.00. The contract terms called for the completion of all work by April 18, 2008. This contract is still in progress.
As of March 20, 2009, the attached list of change orders has been approved. The effect of these change orders resulted in an increase in the amount of $448,263.62 from the original amount awarded of $20,896,800.00. The current contract value is $21,345,063.62. The prior approved change orders reflect a 2.15% increase to the original contract value.
Item 1: A net extra in the amount of $132,443.42 to provide 12 additional hydraulic lines for the six knife-gate valves and to delete the local control stations for the six knife-gate valves. The original contract documents included an individual local control station for each knife-gate valve at elevation -89.00 and a main hydraulic valve control station at elevation -75.00. However, it was later determined that it would be safer to operate the valves at elevation -75.00 by relocating and integrating the valve controls into the main valve control station. Thus, the local control stations at elevation -89.00 are not necessary and should be deleted from the contract. Also, the original drawings did not show sufficient hydraulic lines to allow for the individual control of each knife-gate valve; therefore, additional hydraulic lines are required. The contractor submitted a revised proposal (COR-032) for an extra in the amount of $251,271.25 and a credit in the amount of $118,827.83 for a net extra in the amount of $132,443.42 to complete the work. The engineer reviewed the proposal, found it reasonable, and stated via file letter 673, 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 original contract.
Item 2: A net extra in the amount of $35,257.63 to install flanges and link seals on six 36-inch diameter pipes for pump well numbers 1 and 2. The contract involves the installation of six 36-inch diameter pump discharge pipes through existing wall penetrations. The design plans misrepresented the type of wall penetrations that are to be installed. The change is for field welding of one flange per pipe, recoating of the pipe in the area of the weld, and installation of link seals. The credit work is for not installing water stop fittings, as shown on the drawings. The contractor submitted a proposal (COR-036) in the extra amount of $186,131.02 to complete the work. The engineer reviewed the proposal, found it unacceptable and rejected it via file letter 573. Subsequent negotiations with the contractor failed to reach an agreeable solution. Consequently, the engineer determined the value of the above-mentioned net extra to be $35,257.63, for a credit in the amount of $5,829.19 and an extra in the amount of $41,086.82 and issued file letter 655, which states that the engineer is exercising his power to make a final and binding determination under Article 8 of the General Condition, concerning this work.
This change order is in compliance with the Illinois Criminal Code since the change is germane to the original contract.
It is hereby recommended that the Board of Commissioners authorize the Director of Procurement and Materials Management to execute two change orders to increase Contract 01-353-2M in an amount of $167,701.05 (0.79% of the current contract value) from an amount of $21,345,063.62 to an amount not to exceed $21,512,764.67.
Funds are available in Accounts 401-50000-645650 and 645750.
Requested, Joseph P. Sobanski, Director of Engineering, TEK:JAW

Respectfully Submitted, Barbara J. McGowan, Chairman Committee on Purchasing
