Catalyst Apartments

The Catalyst Apartments are located in Chicago’s West Loop neighborhood on the northeast corner of North Des Plaines and West Washington Street. The 19-story tower is equipped with 223 units featuring amenities including a rooftop deck, pool and private parking garage.

EEA worked with the architect, Brininstool + Lynch, to provide civil and traffic engineering services for the project.

The building’s bustling location required EEA to work closely with the Chicago Department of Transportation to obtain approvals. While conducting the traffic study, the City of Chicago proposed adding bike lanes along the site on Des Plaines Street. To accommodate this change, EEA’s Director of Traffic Engineering coordinated all necessary traffic implications, including changing pedestrian signage and signals for improved safety and traffic flow.

Additionally, EEA managed ground-level parking improvements, utility design, stormwater detention and permitting.
