Body
Dear Sir:
On December 18, 2008, the Board of Commissioners authorized the Director of Procurement and Materials Management to award Contract 01-198-AD Demolition of Sludge Disposal Building and Rehabilitation of Pump and Blower House and Coarse Screen Building at the Stickney Water Reclamation Plant, to IHC Construction Companies, LLC, in an amount not to exceed $28,490,000.00. The scheduled contract completion date was February 2, 2011.
As of March 16, 2012, the attached list of change orders has been approved. The effect of these change orders resulted in an increase in an amount of $2,723,461.84 from the original amount awarded of $28,490,000.00. The current contract value is $31,213,461.84. The prior approved change orders reflect a 9.56% increase to the original contract value.
Item 1: An extra in the amount of $65,318.58 for a new duplex sump pump system. After demolition of the Sludge Disposal Building (SDBX), it was discovered that floor drains in the Pump and Blower House (P&BH) used to empty into a pit that was removed with SDBX. Therefore, a new sump pit and duplex sump pump system needs to be installed to reconnect the remaining floor drains. The pumps will also handle groundwater from the site of the former SDBX, which will now be backfilled and landscaped. The contractor submitted a cost proposal (CCO-057) for an "extra" in the amount of $65,318.58. The engineer reviewed the proposal, found it reasonable, and stated via correspondence 889, that the Engineering Department would recommend its approval.
Item 2: A net credit in the amount of $13,538.19. for not providing floor openings for ductwork. The contract specified to provide new floor openings for a mechanical duct and associated steel support framing at elevations +23 and +30 of the P&BH building. These openings are now determined to be unnecessary as duct openings already exist in the slab. In addition, an existing opening in the concrete roof slab of the southwest screen chamber was not shown on the contract drawing and shall be filled in. The contractor submitted a cost proposal (CCO-035) for an "extra" in the amount of $1,675.35 and a "credit" in the amount of $15,213.54 for a net credit in the amount of $13,538.19. The engineer reviewed the proposal, found it reasonable, and stated via correspondence 890, 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 01-198-AD in an amount of $51,780.39 (0.17% of the current contract value), from an amount of $31,213,461.84, to an amount not to exceed $31,265,242.23.
Funds are available in Accounts 101-50000-612680, 401-50000-645680, and 645780.
