Title
Authority to decrease Contract 04-202-4F Connecting Tunnels and Gates, Thornton Composite Reservoir, Calumet Service Area, to Walsh/II in One Joint Venture in an amount of $18,966.57, from an amount of $137,067,451.17, to an amount not to exceed $137,048,484.60, Account 401-50000-645600, Purchase Order 5001136
Body
Dear Sir:
On May 6, 2010, the Board of Commissioners authorized the Director of Procurement and Materials Management to award Contract 04-202-4F Connecting Tunnels and Gates, Thornton Composite Reservoir, Calumet Service Area, to Walsh/II in One, Joint Venture, in an amount not to exceed $135,475,200.00. This contract was substantially completed on November 26, 2015.
As of April 3, 2020, the attached list of change orders has been approved. The effect of these change orders resulted in an increase in an amount of $1,592,251.17 from the original amount awarded of $135,475,200.00. The current contract value is $137,067,451.17. The prior approved change orders reflect a 1.18% increase to the original contract value.
In 2011, the District erected a permanent fence surrounding the Thornton Transitional Reservoir Dewatering Valve Chamber Building to secure the area. This work conflicted with fencing specified in the contract documents and resulted in a constricted space for the contractor in accessing the existing construction shaft in the area for performing his work. This change order includes the deletion of the contract specified fencing, adjustments to the final layout of the site, and the additional costs associated with accessing the shaft for moving a crane in and out of the constricted space. The contractor submitted a cost proposal (COR-16) for an additional amount of $32,262.16 and a credit in the amount of $51,228.73, for a net credit in the amount of $18,966.57. The engineer reviewed the proposal, found it reasonable, and stated via correspondence 1891, 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 decrease Contract 04-202-4F in an amount of $18,966.57 (0.01% of the current contract value), from an amount of $137,067,451.17, to an amount not to exceed $137,048,484.60.
Funds will be restored in Account 401-50000-645600.
Requested, Catherine A. O’Connor, Director of Engineering, WSS:KMF
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 April 16, 2020
