CHICAGO — Leading environmental engineering and construction firm Brown and Caldwell has opened a new office in the Loop to better serve municipal, federal, and private sector clients in Chicago’s metropolitan area. The new office is located in the Board of Trade Building at 141 West Jackson Boulevard.

The new Chicago office further expands Brown and Caldwell’s growing Midwest presence, adding to its 12 regional locations. Currently providing compliance, permitting, and remediation expertise to numerous Chicagoland Fortune 500 companies, the firm’s Midwest history dates back to the mid-1990s. Notable projects include designing the country’s largest biological phosphorus wastewater plant in the Twin Cities, developing Northeast Ohio’s multimillion-dollar saving chemically enhanced high-rate wastewater treatment program, and designing the first thermophilic anaerobic digestion system in the country located in Duluth.

In the decades since, Brown and Caldwell has continued to serve the Midwest with innovative planning, engineering, and construction solutions to the region’s challenges related to stormwater control and mitigation, energy management, resource recovery, and PFAS regulatory support. Presently, it is engaged as owner’s advisor for the Metropolitan St. Louis Sewer District’s biosolids incineration program, the district’s largest-ever capital project, and is leading the planning and design of multimillion-dollar pumping and water distribution systems in Metro Detroit.
