Mr. Richard Lanyon, General Superintendent
Title
Authority to increase Contract 93-232-2M, Hydraulic Improvements at the Calumet Water Reclamation Plant, to IHC Construction/FHP Tectonics, Joint Venture, in an amount of $6,035.70, from an amount of $120,570,277.24 to an amount not to exceed $120,576,312.94, Accounts 401-50000-645650 and 645750, Purchase Order 5000623
Body
Dear Sir:
On October 19, 2006, the Board of Commissioners passed an order authorizing the Purchasing Agent to award Contract 93-232-2M, Hydraulic Improvements at the Calumet Water Reclamation Plant, to IHC Construction/FHP Tectonics, Joint Venture, in an amount not to exceed $120,890,000.00. The scheduled contract date for this contract is April 26, 2010.
As of December 5, 2008, the attached list of change orders has been approved. The effect of these change orders resulted in a decrease in the amount of $319,722.76 from the original amount awarded of $120,890,000.00. The current contract value is $120,570,277.24. The prior approved change orders reflect a 0.26% decrease to the original contract value.
The contract includes the installation of a stone basket at the influent end of the new pumping station to trap heavy solids to protect downstream equipment. After further evaluation, the design of the stone basket does not appear to be robust enough to resist the force of the raw sewage flow at peak velocities.
The contractor submitted a cost proposal (COR -025) for an extra in the amount of $10,573.20 to fabricate a structurally enhanced stone basket and a credit in the amount of $4,537.50 to delete the originally designed stone basket for a net extra in the amount of $6,035.70. The engineer reviewed the proposal, found it reasonable, and stated via file letter 425, that the Engineering Department would recommend its approval.
The change order is in compliance with the Illinois Criminal Code since this change order is germane to the contract.
It is hereby requested that the Board of Commissioners authorize the Purchasing Agent to execute a change order to increase Contract 93-232-2M in an amount of $6,035.70 (0.005% of the current contract value) from an amount of $120,570,277.24 to an amount not to exceed $120,576,312.94.
Funds are available in Accounts 401-50000-645650 and 645750.
Requested, Joseph P. Sobanski, Chief Engineer, TEK:ECB
