As part of the $7.3 billion “Building a New Chicago” infrastructure renewal plan, the 110-year-old pumping station at Springfield Avenue was completely overhauled and brought into the 21st century, targeting LEED certification.
The project sought to reduce the station’s carbon emissions by 17,380 tons per year by replacing steam turbines and boilers with electric motors, saving more than $7.5 million in annual energy and operating costs. Each motor features four ComEd feeds, new controls, and variable frequency drives (VFDs) for each of the pumps, which were replaced in phases throughout the duration of the project.
The revitalized station also includes a 30-kilowatt photovoltaic array, which is designed to produce 40.7 megawatt hours of electricity annually and reduces carbon emissions by sixteen tons. The electricity from the array is used to power the building’s upgraded auxiliary systems.
Cotter served as a subconsultant to provide construction inspection services for the project, including inspection and management of equipment start-up and commissioning for the historic station.
