CHICAGO, IL – Truss 1 was removed yesterday! With all the steel purlins removed from Truss 1 to the west wall and between Truss 1 & Truss 2, the truss was prepped for removal. A large crane staged on 64th Street held the truss in tension with the use of a spreader rod that was attached in two places to the truss. Iron workers released the steel on the south side first and attached a tether to hold it in place. Then the steel on the north side was released, allowing for the crane to lift the truss up over the north parapet wall and lay it on the ground.
Success! The first truss is out – now starts the prep work for installing the new truss!
