Precision steel detailing delivered on time, every time.

Ken Boitz & Associates has spent over 40 years detailing steel as part of some of Chicago’s most illustrious architecture. We take pride in the essential part our work plays in the backbone of our city, and we take pride in delivering precision work on time for our clients.

While KBA has made our name detailing steel on some of Chicago’s most iconic buildings, we are proud to handle a broad range of projects in our community. Light and heavy structures, high rise buildings, rails, stairways - if steel structure is involved, we handle it. KBA ensures that our clients have what they need to get the job started on time, and get the job done right.
