Body
Dear Sir:
On February 7, 2008, the Board of Commissioners authorized the Director of Procurement and Materials Management to award Contract 04-299-2P Improvements to Aeration Batteries A, B, C, E1, and E2 at Calumet Water Reclamation Plant (WRP), to F.H. Paschen/S.N. Nielsen & Associates, L.L.C., in an amount not to exceed $20,391,000.00. The contract expires on March 7, 2011.
As of June 19, 2009, the attached list of change orders has been approved. The effect of these change orders resulted in an increase in the amount of $34,766.51 from the original amount awarded of $20,391,000.00. The current contract value is $20,425,766.51. The prior approved change orders reflect a 0.17% increase to the original contract value.
Item 1: An extra in the amount of $50,993.80 to replace three drops and diffusers in Batteries E1 and E2 at the Calumet WRP. The contract involves the replacement of diffusers and drop piping in the aeration batteries. During field verification of the existing and new work to be performed, the contractor discovered that there were two four-inch drop pipes and diffusers that were not shown on the demolition plans and three that were not shown on the new work plans. The installation of the new drop pipes and diffusers is necessary for the proper aeration of the mixing channels in Batteries E1 and E2. The contractor submitted a proposal (COR-005) in the amount of $50,993.80 to complete the work. The engineer reviewed the proposal, found it reasonable, and stated via correspondence 194, 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 original contract as signed.
Item 2: A net extra in the amount of $17,940.75 to change two strainers from in-line type to floor mounted type and to relocate them to an adjacent room at the Calumet WRP. A portion of the contract involves the installation of strainers on the effluent water system. The contract plans indicated the strainers to be an in-line type, whereas a floor mounted type was required. The work includes furnishing and installing floor mounted strainers with concrete pads and associated piping in an adjacent room. The contractor submitted a proposal (COR-006) for an extra in the amount of $19,465.49 and a credit in the amount of $1,524.74 for a net extra in the amount of $17,490.75 to complete the work. The engineer reviewed the proposal, found it reasonable, and stated via correspondence 208, that the Engineering Department would recommend its approval.
This change order is in compliance with the Illinois Criminal Code since the change germane to the original contract as signed.
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 04-299-2P in an amount of $68,934.55 (0.34% of the current contract value) from an amount of $20,425,766.51 to an amount not to exceed $20,494,701.06.
Funds are available in Accounts 101-50000-612650, 401-50000-645650, and 645750.
