Title
Authority to increase Contract 05-836-3D Lockport Power House Sluice Gate Replacement, South Service Area, to IHC Construction Companies, LLC in an amount of $29,543.48, from an amount of $13,036,567.73, to an amount not to exceed $13,066,111.21, Account 401-50000-645720, Purchase Order 5000871
Body
Dear Sir:
On April 3, 2008, the Board of Commissioners authorized the Director of Procurement and Materials Management to award Contract 05-836-3D Lockport Power House Sluice Gate Replacement, South Service Area, to IHC Construction Companies, LLC, in an amount not to exceed $11,227,400.00. The scheduled contract completion date was April 29, 2012.
As of May 4, 2012, the attached list of change orders has been approved. The effect of these change orders resulted in an increase in an amount of $1,809,167.73 from the original amount awarded of $11,227,400.00. The current contract value is $13,036,567.73. The prior approved change orders reflect a 16.11% increase to the original contract value.
The contract involves replacement of the nine leaking sluice gates, which control the water level of the Chicago Sanitary and Ship Canal.
A problem was discovered with the top seals of the three new gates installed in Bay 7 under this contract. After installation, it was observed that the top horizontal J-seals of all three gates in Bay 7 got wedged between the gate and the concrete above the gate opening when the gates were raised to open. To resolve this problem, the top seal of Gate 7A was replaced with a smaller seal and the concrete immediately above the gate opening was cut back under CCO-010, issued on September 1, 2011. The gate seal was successfully tested. Since this solution has solved the problem, it is necessary to make the same modifications at Gates 7B and 7C. The contractor submitted a cost proposal (CCO-014) for an extra in the amount of $29,543.48. The engineer reviewed the cost proposal, found it reasonable, and stated via correspondence 275, 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 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 05-836-3D in an amount of $29,543.48 (0.23% of the current contract value), from an amount of $13,036,567.73, to an amount not to exceed $13,066,111.21.
Funds are available in Account 401-50000-645720.
Requested, Thomas E. Kunetz, Assistant Director of Engineering, TEK:JKK
Recommended, Darlene A. LoCascio, Director of Procurement and Materials Management
Respectfully Submitted, Barbara J. McGowan, Chairman Committee on Procurement
