Mr. David St. Pierre, Executive Director
Title
Authority to increase purchase order and amend the agreement with Environmental Design International, Inc., for professional services in connection with Contract 14-260-5C, Preliminary Engineering for a Flood Control Project in the Washington Street Area of Blue Island, Illinois in an amount of $13,500.00, from an amount of $273,022.38, to an amount not to exceed $286,522.38, Account 501-50000-612440, Purchase Order 3083385
Body
Dear Sir:
On October 2, 2014, the Board of Commissioners authorized the Director of Procurement and Materials Management to issue a purchase order and enter into an agreement with Environmental Design International, Inc. (EDI), for professional services in connection with Contract 14-260-5C, Preliminary Engineering for a Flood Control Project in the Washington Street Area of Blue Island, Illinois, in an amount not to exceed $273,022.38. The scheduled contract completion date is May 31, 2018.
This contract has no prior change orders.
Through the preliminary engineering analysis performed under the captioned project, several alternatives to address overland flooding in the Washington Street project area were identified. Various combinations of green and gray stormwater infrastructure were analyzed and a recommendation was made for a new relief sewer along with GI improvements in the public right-of-way, however, it was determined that these improvements would not effectively address basement backup flooding occurring in the combined sewer area.
The District, along with EDI and the City of Blue Island, have reviewed additional solutions to address both the overland and basement backup flooding problems, including potential use of vacant property recently acquired by the city in the project area, and alterations to the existing combined sewer system. In order to evaluate these additional alternatives, hydrologic and hydraulic modeling and supplemental engineering analysis is required. EDI has submitted to the District a change order proposal in an amount not to exceed $13,500.00 for this additional alternatives analysis.
This change order is in compliance with the Illinois Criminal Code since the change is due to circumstances 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 the purchase order and amend the agreement in an amount of $13,500.00 (4.94% of the current contract value), from an amount of $273,022.38, to an amount not to exceed $286,522.38.
Funds are available in Account 501-50000-612440.
Requested, Marcella V. Landis, Acting 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 December 21, 2017
