In connection with Contract 23-170-3C Hydraulic Modeling of the Mainstream Tunnel System, authorized by the Board on May 18, 2023, InfoWorks software will be used for hydrologic and hydraulic modeling of the Mainstream Tunnel and Reservoir Plan (TARP) Systems. The City of Chicago (City) has already completed an InfoWorks model that includes the City’s sewers as well as District interceptor sewers, interceptor connecting structures and TARP connecting structures. In a cooperative effort to share available information, it is recommended to enter into an Intergovernmental Agreement (IGA) with the City to obtain their complete InfoWorks model, including any future updates or upgrades, for use with the District’s TARP System model. In turn, the District will share its TARP hydraulic model with the City, including any future updates or upgrades.
A similar request was authorized by the Board on December 15, 2011. The previous IGA with the City expired on March 14, 2022.
Based on the foregoing, it is requested that the Board of Commissioners grant authority to enter into an IGA with the City to obtain and use their InfoWorks model and that the Chairman of the Committee on Finance, Executive Director and Clerk be authorized to execute said IGA on behalf of the District, as well as any documents necessary to effectuate the transaction and conveyance, upon approval by the Director of Engineering as to technical matters and by the General Counsel as to form and legality.
Requested, Catherine A. O’Connor, Director of Engineering, KMF:LS
