Project Overview

A single grain bin, under construction, at a rural farming operation near Craig, Iowa is claimed to have sustained damage during a wind storm.  Pie was requested to evaluate the condition of installed and uninstalled portions of the grain bin structure and to offer an engineering opinion as to the cause of any damage sustained.

Based on a review of the available information and Pie’s observations, a determination based on a reasonable degree of engineering certainty showed that the lack of an appropriately designed and installed temporary bracing system to provide stability of the structure during the erection process was causal to the grain bin failure.  Although the loading condition created by the wind storm event initiated the collapse of the bin, it was determined that the documented wind speed of 68 miles per hour would not be sufficient to cause the damage observed, if the structure had been properly braced.
