Since 1973, JKC has served as the excavation division to many of Chicago’s top general contractors, providing world-class site preparation, excavation, demolition, structural earthwork and shoreline development on projects that have remade Chicago’s skyline, landscape and shoreline.

With state-of-the-art equipment, meticulous processes, and a decades-long track record of reliable execution, JKC has set the pace for other contractors on many of the area’s largest and most complex projects: at O’Hare International Airport, Argonne National Laboratory, The Obama Presidential Center, the University of Chicago, and countless other landmarks, facilities, data centers, and mansion shorelines.

Among the keys to our success over five decades:

Excavation’s dirty little secret: even with the best planning and execution, unforeseen problems can be encountered when you dig into the ground. Do you want to work with an excavator who is stumped by every complication, leaving you to figure it out? When you work with JKC, you get a seasoned partner with a track record of preventing and managing complications thoroughly, carefully and expediently.
