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 April 20, 2012, the attached list of change orders has been approved. The effect of these change orders resulted in an increase in the amount of $1,492,586.78 from the original amount awarded of $162,232,344.00. The current contract value is $163,724,930.78. The prior approved change orders reflect a 0.92% increase to the original contract value.
Additional work is required to resolve the underground conflicts between the new electrical duct bank leading to the Area 31-Gravity Thickening Support Building substation and existing underground pipes and structures. Multiple conflicts between the new underground electrical duct bank and existing underground pipelines and structures exist. In order to install the new electrical duct bank, the underground interferences need to be resolved. The work includes reducing the depth of 2 communication manholes, revising the communication and data duct bore and jack from two 20" casings to one 30" casing, revising the power duct bank bore and jack from one 60" casing to one 30" and two 24" casings, increasing the length of communication and data duct bore and jack by approximately 66', increasing the length of power duct bank bore and jack by approximately 44' for the 30"casing, 53' for one 24" casing, and 59' for the other 24" casing, reducing the length of open cut communication and data duct installation by approximately 68', reducing the length of open cut power duct bank installation by approximately 63', and increasing the depth of the bore pit in drying bed 12 from 14' to 24'. The contractor submitted a cost proposal (CCO-080) for an extra in the amount of $1,976,593.94 and a credit in the amount of $1,366,658.16, for a net extra in the amount of $609,935.78. The engineer reviewed the proposal, found it to be reasonable, and stated via correspondence 2832, 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 $609,935.78 (0.37% of the current contract value), from an amount of $163,724,930.78, to an amount not to exceed $164,334,866.56.
