Body
Dear Sir:
On July 14, 2011, the Board of Commissioners authorized the Director of Procurement and Materials Management to award Contract 06-023-3P Stop Logs and Diversion Pumps at Wilmette Pump Station and Evanston Pump Station (PS) Rehabilitation, North Service Area, to F.H. Paschen/S.N. Nielsen, in an amount not to exceed $17,440,000.00. The scheduled contract completion date is September 29, 2013.
As of May 3, 2013, the attached list of change orders has been approved. The effect of these change orders resulted in an increase in an amount of $242,050.19 from the original amount awarded of $17,440,000.00. The current contract value is $17,682,050.19. The prior approved change orders reflect a 1.39% increase to the original contract value.
Item 1: A net extra in the amount of $13,465.00 for supplying and installing an alternative support system for the Modular Air handling Unit (MAU) in the Evanston PS. The modification is required because the existing concrete ceiling was found to be unsuitable for anchoring the MAU support bars in some locations. The unit weights one ton and is designed to be supported from the ceiling. The work includes a new mounting system with modified anchoring locations and providing custom manufactured wall brackets in lieu of the specified wall brackets. The contractor submitted a cost proposal (CCO-012) for an extra in the amount of $13,960.00 and a credit in the amount of $495.00, for a net extra in the amount of $13,465.00. The engineer reviewed the proposal, found it to be reasonable, and stated via correspondence 462, that the Engineering Department would recommend its approval.
Item 2: A net extra in the amount of $6,029.00 to modify the installation of the new sanitary force-main at the Wilmette PS. The work includes installing 4" High Density Polyethylene pipe using trenchless technology in lieu of installing Ductile Iron pipe by open cut excavation. This method is advantageous to the District because it minimizes the disruption to the existing bridge embankment. Also, the work includes the installation of additional check valves, a shut-off valve, and a clean-out assembly on the new force-main in the pump room to provide additional protection against flooding. The contractor submitted a cost proposal (CCO-015) for an extra in the amount of $28,141.00 and a credit in the amount of $22,112.00, for a net extra in the amount of $6,029.00. The engineer reviewed the proposal, found it to be reasonable, and stated via correspondence 467, 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 due to circumstances not reasonably foreseeable at the time the contract was signed, and are in the best interest of the District.
It is hereby recommended that the Board of Commissioners authorize the Director of Procurement and Materials Management to execute the two change orders to increase Contract 06-023-3P in an amount of $19,494.00 (0.11% of the current contract value), from an amount of $17,682,050.19, to an amount not to exceed $17,701,544.19.
Funds are available in Accounts 101-50000-612620, 401-50000-645620 and 645720.
Requested, Catherine A. O'Connor, Director of Engineering, MVL:ECB
