Title
Authority to increase Contract 06-212-3M Calumet TARP Pump Station Improvements, Calumet Water Reclamation Plant, to Sollitt/Sachi/Alworth JV in an amount of $139,324.00, from an amount of $37,025,800.93, to an amount not to exceed $37,165,124.93, Account 401-50000-645600, Purchase Order 5001404
Body
Dear Sir:
On May 2, 2013, the Board of Commissioners authorized the Director of Procurement and Materials Management to award Contract 06-212-3M Calumet TARP Pump Station Improvements, Calumet Water Reclamation Plant, to Sollitt/Sachi/Alworth JV, in an amount not to exceed $35,067,000.00. The scheduled contract completion date was May 19, 2018.
As of November 2, 2018, the attached list of change orders has been approved. The effect of these change orders resulted in an increase in an amount of $1,958,800.93 from the original amount awarded of $35,067,000.00. The current contract value is $37,025,800.93. The prior approved change orders reflect a 5.59% increase to the original contract value.
This contract includes the replacement of the four large and two small Calumet TARP pumps with six new 72 MGD pumps, motors and variable frequency drives (VFDs). The pump motors are driven by the VFDs which allow for the operator to adjust the pump flow under various head conditions. The VFDs are rated 4,160 Vac and require a step down transformer from 13,200 Vac to 4,160 Vac. During construction, it was identified that due to the locations of the new transformers, the interconnections between the transformers and the VFDs required conduit and cable instead of being connected directly by bus work. The contractor submitted a cost proposal (CCO-055) in the amount of $139,324.00. The engineer reviewed the proposal, found it to be reasonable, and stated via correspondence 896, 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 06-212-3M in an amount of $139,324.00 (0.38% of the current contract value), from an amount of $37,025,800.93, to an amount not to exceed $37,165,124.93.
Funds are available in Account 401-50000-645600.
Requested, Catherine A. O’Connor, Director of Engineering, ECB:LMK
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 November 15, 2018
