Performed swingstage drops on the exterior of the building, identified locations of cracking, and surveyed typical crack patterns

Observed panel interior surfaces and panel structural supports to ascertain the cause of the cracking and to assess the current condition of the panel supports

Concluded the GFRC panels were cracking due to a lack of flexibility in the structural supports, which were constructed in a manner that precludes the panels from relieving thermal stresses during daily heating and cooling (expansion and contraction) cycles

Observed that the existing structural supports were relatively free of corrosion and appeared adequate to continue supporting the panels

Recommended initiation of a regular maintenance program to help limit water intrusion and to monitor the cracking in the panels

Provided recommendations for routing and sealing the cracks in the GFRC panels
