Case Studies: Inadequate Bracing During Construction

Pie was retained to determine the cause of a roof truss failure at a retail building that was under construction.  The contractor alleged that a gust of wind caused the roof system to fail over a holiday weekend.

We conducted an observation and took measurements at the site and reviewed the construction documents.  Based on our investigation, it was determined that the roof trusses temporary bracing during construction was inadequate.

Pie determined that while the wind forces may have initiated the collapse, it was not the root cause of the collapse.  If the structure had adequate temporary bracing during construction, the wind forces would not have initiated the failure.
