  ABOUT US  

BUILDING
EXCELLENCE

We have the expertise to tackle your largest and most complicated precast projects and engineered steel structures.

We’ve built high-rises, hospitals, and college complexes. We’ve set steel with an 800 ton crane off a barge in the Chicago River, and designed and implemented our own in-house floating fall protection netting system. Through it all, through our growth, through the changes in the industry, our goal has stayed the same; to make our customers look good.

  COMMITTED TO DIVERSITY 

Complex Structures Group is certified with the National Minority Supplier Development Council (NMSDC).  Founded in 1972, NMSDC is the longest-operating business growth engine for the broadest group of systematically excluded communities of color (Asian-Indian, Asian-Pacific, Black, Hispanic, and Native American), and its impact goes far beyond supply chain. It’s about upward mobility for the emerging majority of Americans, an equal shot at participating in the American experiment of free-market capitalism and entrepreneurship.
