Body
Dear Sir:
On January 17, 2013, the Board of Commissioners authorized the Director of Procurement and Materials Management to award Contract 04-131-2D Rehabilitation of the A/B and C/D Service Tunnels - Phase One, Stickney Water Reclamation Plant (WRP), to F.H. Paschen/S.N. Nielsen, in an amount not to exceed $13,615,000.00. The scheduled contract completion date is August 8, 2016.
As of March 20, 2015, the attached list of change orders has been approved. The effect of these change orders resulted in an increase in an amount of $105,290.69 from the original amount awarded of $13,615,000.00. The current contract value is $13,720,290.69. The prior approved change orders reflect a 0.77% increase to the original contract value.
Item 1: A net extra in the amount of $21,526.69 is necessary to perform the following work: a) Install 61 additional mechanical couplers for connecting new rebars to existing rebars in the tunnel roof beams as per RFI-065; b) Delete a 6' long straight section of handrail from the contract in order to allow access to the concrete steps leading to the Pump and Blower house, and install new handrails on both sides of the concrete steps as per RFI-073; and c) Install a new backflow preventer at MH-11. The contractor submitted a cost proposal (CCO-15) for an extra in the amount of $23,026.69 and a credit in the amount of $1,500.00, for a net extra in the amount of $21,526.69. The engineer reviewed the proposal, found it to be reasonable, and stated via correspondence 443, that the Engineering Department would recommend its approval.
Item 2: A net extra in the amount of $22,232.98 to enlarge the floor slab openings to accommodate new ductwork for exhaust fans EF-1 and EF-2. The existing openings are not large enough to accommodate the new ductwork, and therefore additional selective demolition of the slabs is required. The contractor submitted a cost proposal (CCO-16) for an extra in the amount of $22,232.98. The engineer reviewed the proposal, found it to be reasonable, and stated via correspondence 444, 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 04-131-2D in an amount of $43,759.67 (0.32% of the current contract value), from an amount of $13,720,290.69, to an amount not to exceed $13,764,050.36.
Funds are available in Account 401-50000-645750.
Requested, Catherine A. O'Connor, Director of Engineering, MVL:JKK
Recommended, Darlene A. LoCascio, Director of Procurement and Materials Management
Respectfully Submitted, Barbara J. McGowan, Chairman Committee on Procurement
