Authority to increase Contract 09-176-3P Sludge Thickening Facilities, Stickney Water Reclamation Plant, to McHugh Construction, in an amount of $97,101.43 from an amount of $165,195,650.23, to an amount not to exceed $165,292,751.66, 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 April 12, 2014.
As of December 21, 2012, the attached list of change orders has been approved. The effect of these change orders resulted in an increase in the amount of $2,963,306.23 from the original amount awarded of $162,232,344.00. The current contract value is $165,195,650.23. The prior approved change orders reflect a 1.83% increase to the original contract value.
Item 1: A net extra in the amount of $43,101.43 to allow the Distributed Control System (DCS) to control (open/close) the odor control fan dampers in the Area 30 - Gravity Thickening Building. The contract documents do not have provisions for DCS control of the dampers. The DCS control is required to allow Maintenance and Operations staff to increase air changes in the Area 30 building during occupancy and to decrease air changes while unoccupied to reduce energy usage. The work includes furnishing and installing additional wiring and digital output cards. Also, the conduit sizes need to be increased and additional DCS programming is required. The contractor submitted a cost proposal (CCO-127) for an extra in the amount of $51,329.44 and a credit in the amount of $8,228.01, for a net extra of $43,101.43. The engineer reviewed the proposal, found it to be reasonable, and stated via correspondence 3410, that the Engineering Department would recommend its approval.
Item 2: An extra in the amount of $54,000.00 to revise the I/O feeds to the Level Indicating Transmitter (LIT) and Flow Indicating Transmitter (FIT) instruments in Areas 22, 23, 24 and 51.The LITs and FITs are required in order to provide a functional sludge pumping system. The contract documents call for power terminations for the LITs and FITs in the Remote Input-Output (RIO) cabinets, which do not have the necessary space allocations. Instrument power needs to be provided to the LITs and FITs directly from the power panels rather than the RIO cabinets. The work includes installing junction boxes (JB) at each of the four RIO cabinets, installing 20A feeders to each JB, connecting 28 instruments to the associated JBs to provide 120V power, and installing disconnect safety switches. The contractor submitted a cost proposal (CCO-144) for an extra in the amount of $54,000.00. The engineer reviewed the proposal, found it to be reasonable, and stated via correspondence 3382 that the Engineering Department would recommend its approval.
The above two change orders are in compliance with the Illinois Criminal Code since the changes are germane to the 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 09-176-3P in an amount of $97,101.43 (0.06% of the current contract value) from an amount of $165,195,650.23 to an amount not to exceed $165,292,751.66.
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
