The purpose of this project was to provide a new roof to the existing Nalco building in Bedford Park, Ill. (a Chicago suburb) without interrupting the chemical production within the facility. The steel joists were designed to simple span 116’ over the existing roof and are supported by new structural steel framing.

Once the steel joists and deck were installed, the existing roof was selectively demolished. With the roof at a higher elevation, the owner was able to continue the chemical products production with minimal interruption. Since the interior existing walls were to remain in place, the joists have braces welded from the chords and deck to the walls.
