Mr. Brian A. Perkovich, Executive Director

 

Title

Authority to increase Contract 14-263-3F Melvina Ditch Reservoir Improvements, to F.H. Paschen, S.N. Nielsen & Associates LLC in an amount of $331,993.44, from an amount of $15,342,475.49, to an amount not to exceed $15,674,468.93, Account 401-50000-645620, Purchase Order 4000052

Body

 

Dear Sir:

 

On November 2, 2017, the Board of Commissioners authorized the Director of Procurement and Materials Management to award Contract 14-263-3F Melvina Ditch Reservoir Improvements to F.H. Paschen, S.N. Nielson & Associates, LLC, in an amount not to exceed $14,245,000.00, plus a five (5) percent allowance for change orders in an amount of $712,250.00, for a total amount not to exceed $14,957,250.00.  The contract completion date is June 21, 2021.

 

As of July 17, 2020, the attached list of change orders has been approved. The effect of these change orders resulted in an increase amount of $1,097,475.49 from the original amount of $14,245,000.00. The current contract value is $15,342,475.49. The prior approved change orders reflect a 7.70% increase to the original contract value. 

 

A new 60-inch diameter low flow storm sewer was installed as part of the reservoir expansion to minimize operation of the existing sump pumps.  During recent storm events geysering occurred through the 60-inch storm sewer at manholes along the pipe, allowing flow into the reservoir prematurely. In order to address this issue, modifications to the 60-inch storm sewer as well as the manholes to reduce pressure loss and resolve the geysering have been designed. These modifications are necessary for the reservoir to operate properly.  The contractor submitted a cost  proposal (CO-49) for an extra in an amount of $331,993.44. The engineer reviewed the proposal, found it to be reasonable, and stated via correspondence CO49, that the Engineering Department would recommend its approval.

 

The above change order is in compliance with the Illinois Criminal Code since the changes are germane to the original contract as 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 14-263-3F in an amount of $331,993.44 (2.16% of the current contract value), from an amount of $15,342,475.49, to an amount not to exceed $15,674,468.93.

 

Funds are available in Account 401-50000-645620.

 

Requested, Catherine A. O’Connor, Director of Engineering, WSS:JK

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 August 6, 2020.
