Authority to increase Contract 01-353-2M Rehabilitation of the Existing Influent Pumping Station at Kirie Water Reclamation Plant, to Rausch Construction Company, in an amount of $21,911.86, from an amount of $21,692,728.65 to an amount not to exceed $21,714,640.51, Accounts 401-50000-645650 and 645750, Purchase Order 5000394
Body
Dear Sir:
On May 5, 2005, the Board of Commissioners authorized the Director of Procurement and Materials Management to award Contract 01-353-2M, Rehabilitation of the Existing Influent Pumping Station at Kirie Water Reclamation Plant, to Rausch Construction Company, in an amount not to exceed $20,896,800.00. The scheduled contract completion date was April 18, 2008. This contract is still in progress.
As of April 16, 2010, the attached list of change orders has been approved. The effect of these change orders resulted in an increase in the amount of $795,928.65 from the original amount awarded of $20,896,800.00. The current contract value is $21,692,728.65. The prior approved change orders reflect a 3.81% increase to the original contract value.
The contract includes installation of six adjustable speed drive (ASD) units. The contract documents directed installation of control conduits and wiring for ASD Nos. 4 and 6 through the bottom of the ASDs. During core drilling through the concrete floor for the conduit openings, it was discovered that the embedded rebars in the concrete floor were not in the locations that were shown on the as-built drawings. The presence of the rebars prevented a full-core penetration of the floor. Therefore, the conduits need to be rerouted through the nearby pipe chase from the basement into the ground floor ceiling space and into ASD Nos. 4 and 6 from above. The work on ASD No. 4 is completed. Before the engineer’s determination on the change order, the contractor proceeded with the work in its own best interest in executing the overall project. The engineer has now determined that this work is additional scope to the project. The contractor submitted a proposal (RCC-279) in the extra amount of $20,909.68 to complete the work on both ASD Nos. 4 and 6. The engineer reviewed the proposal, found it unacceptable and rejected it via file letter 744. The contractor submitted a revised “extra work” cost proposal in the amount of $21,911.86. The engineer reviewed the proposal, found it excessive and decided via file letter 840 to proceed on a time and material basis for an amount not to exceed $21,911.86.
This change order is in compliance with the Illinois Criminal Code since the change is due to circumstances that were not reasonably foreseeable at the time the contract was signed, and is 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 a change order to increase Contract 01-353-2M in an amount of $21,911.86 (0.10% of the current contract value) from an amount of $21,692,728.65 to an amount not to exceed $21,714,640.51.
Funds are available in Accounts 401-50000-645650 and 645750.
Requested, Kenneth A. Kits, Acting Director of Engineering, TEK:JAW
Recommended, Darlene A. LoCascio, Director of Procurement and Materials Management
Respectfully Submitted, Barbara J. McGowan, Chairman Committee on Procurement
Disposition of this agenda item will be documented in the official Regular Board Meeting Minutes of the Board of Commissioners for May 6, 2010
