TRANSMITTAL LETTER FOR BOARD MEETING OF AUGUST 29, 2013
COMMITTEE ON PROCUREMENT
Mr. David St. Pierre, Executive Director
Title
Authority to increase purchase order and amend the agreement with the University of Illinois at Urbana-Champaign, for professional engineering services for Agreement 07-164-3C, TARP Modeling - Phase II of the Mainstream and Des Plaines TARP Systems, in an amount not to exceed $151,946.00, from an amount of $1,989,833.00, to an amount not to exceed $2,141,779.00, Account 401-50000-601410, Purchase Order 3067358
Body
Dear Sir:
On February 17, 2011, the Board of Commissioners authorized the Director of Procurement and Materials Management to issue a purchase order and enter into an agreement with the University of Illinois at Urbana-Champaign (U of I), to perform professional engineering services for Agreement 07-164-3C, TARP Modeling - Phase II of the Mainstream and Des Plaines TARP Systems, in an amount not to exceed $1,989,833.00. The agreement is scheduled to expire August 31, 2013.
No prior change orders exist.
This agreement was conducted under the auspices of the Master Agreement between the U of I and the District, authorized by the Board of Commissioners at the Board Meeting of September 19, 2002, and amended to extend the termination date by the Board of Commissioners at the Board Meetings of October 16, 2003, May 3, 2007, December 16, 2010 and March 15, 2012. The Master Agreement expires December 31, 2015. The purpose of the Master Agreement was to allow the District to directly take advantage of the expertise offered by the U of I Department of Civil and Environmental Engineering. This agreement has been used for hydraulic model studies of the Calumet Pumping Station, Calumet Water Reclamation Plant settling tanks, sediment management in the SEPA stations, Phase I, II and III Modeling of the Calumet TARP System, and Phase I and II Modeling of the Mainstream and Des Plaines TARP Systems.
Phase I, II and III Modeling of the Calumet TARP System and Phase I Modeling of the Mainstream and Des Plaines TARP Systems are complete. Currently, U of I is progressing on Phase II Modeling of the Mainstream and Des Plaines TARP Systems.
The District has requested U of I to expand the original scope of work of this agreement to include model simulations to examine the feasibility of using existing Mainstream TARP tunnels and structures to convey flows from the North Branch of the Chicago River in the Albany Park area to the North Shore Channel during flood events. These simulations will examine the head required to convey the flows to the North Shore Channel and determine where the flow will exit the TARP system. The District also requested U of I to perform a series of model simulations to determine the critical duration of flows from the Des Plaines TARP tunnel into the McCook Reservoir for the Army Corps of Engineers use in designing this tunnel connection to the McCook Reservoir.
Authorization is requested to increase the purchase order and amend the agreement with U of I to expand the original scope of work of the agreement and extend the completion date to December 31, 2013. It is estimated that this work will cost $151,946.00. This amendment to the agreement is in compliance with the Illinois Criminal Code since the change is due to circumstances not reasonably foreseeable at the time the agreement was signed, and is in the best interest of the District.
It is hereby requested that the Board of Commissioners authorize the Director of Procurement and Materials Management to increase the purchase order and amend the agreement in an amount of $151,946.00 (7.64% of the current agreement value), from an amount of $1,989,833.00 to an amount not to exceed $2,141,779.00.
Funds are available in Account 401-50000-601410.
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 August 29, 2013
