Overcoming Challenges

To help remove the curtainwall, Walters developed a custom jig apparatus specifically designed to remove sections of the wall face. The device engages the curtain wall and releases sections that can then be lowered down.

This work was particularly crucial given the high profile, high pedestrian traffic location of the building. Safety, and the perception of safety were both exceptionally important to this job.
