Title
Authority to increase Contract 09-176-3P Sludge Thickening Facilities, Stickney Water Reclamation Plant, to McHugh Construction in an amount of $26,531.98, from an amount of $166,446,038.16, to an amount not to exceed $166,472,570.14, Account 401-50000-645650, Purchase Order 5001115
Body
Dear Sir:
On March 18, 2010, the Board of Commissioners authorized the Director of Procurement and Materials Management to award Contract 09-176-3P Sludge Thickening Facilities, Stickney Water Reclamation Plant, to McHugh Construction, in an amount not to exceed $162,232,344.00. The scheduled contract completion date is November 11, 2016.
As of November 7, 2014, the attached list of change orders has been approved. The effect of these change orders resulted in an increase in an amount of $4,213,694.16 from the original amount awarded of $162,232,344.00. The current contract value is $166,446,038.16. The prior approved change orders reflect a 2.60% increase to the original contract value.
Additional work is required to make modifications to the sluice gates in the Area 21 sludge channels. It has been determined that the detail provided in Section C-C on Contract Drawing P-21-02 does not provide for a watertight connection between the spacer plate and weir plate. The sluice gates must be watertight to the top of the weir plates. Therefore, the scope of additional work is as follows: weld the weir plates to the spacer plates on all six gates with no less than a 1/4" continuous weld. All necessary surface preparation and cleaning to assure watertight connections shall be performed prior to welding. The contractor submitted a cost proposal (CCO-198) for an extra in the amount of $26,531.98. The engineer reviewed the proposal, found it to be reasonable, and stated via correspondence 5032, 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 09-176-3P in an amount of $26,531.98 (0.02% of the current contract value), from an amount of $166,446,038.16, to an amount not to exceed $166,472,570.14.
Funds are available in Account 401-50000-645650.
Requested, Catherine O'Connor, Director of Engineering, MVL:ECB
Recommended, Darlene A. LoCascio, Director of Procurement and Materials Management
Respectfully Submitted, Barbara J. McGowan, Chairman Committee on Procurement
