John Corradetti

Project Manager with Case Foundation
Mr. Corradetti has been at Case Foundation since 2015 with a role as project manager in their caisson division. Key projects in which he has overseen drilled shaft construction are the O’Hare Airport Consolidated Rental Car Facility; I-29 over the Floyd River in Sioux City, Iowa; and I-40 over the White River near Little Rock, Arkansas, as well as a host of building projects in downtown Chicago. Key responsibilities include bidding and managing deep foundation projects in the Midwest with emphasis on top-of-rock, rock-socketed, and large-diameter caissons. Prior to Case Foundation, Mr. Corradetti worked on large scale projects that involved large-diameter drilled shafts in roles as a general contractor including the I-15 north corridor design-build in Las Vegas, Nevada, and the reconstruction of the BNSF lift bridge in Burlington, Iowa. He completed his undergraduate work at the University of Illinois at Urbana-Champaign (2007), obtained an MS degree in Construction Engineering and Management at Illinois Institute of Technology (2015), and recently finished his M.B.A. degree at the University of Illinois at Chicago.
