The Indiana State Fair Commission will pay more than $2 million for the investigations into the Aug. 13 stage collapse.
According to contracts, the Commission will pay Thornton Tomasetti $1.6 million. The Commission will also pay $500,000 to Witt Associates.
Thursday, the two independent companies released their findings concerning the stage's rigging and the actions taken before and after the collapse, which killed seven people and injured dozens more.
Thornton Tomasetti found the stage's failure was due to an "inadequate lateral system."
Their report stated the stage was built to withstand winds up to nearly 70 miles per hour. The estimated wind speed at the time of the collapse was 59 miles per hour. Despite the stage's wind sustainability, the jersey barriers around the stage shifted. That shift caused the stage's load to redistribute and ultimately the stage collapsed, according to their report.
Witt Associates' investigation focused more on the preparedness of all parties involved prior to the collapse. The company found the emergency plans and procedures in place were not fully developed.
Their report, however, stated that the response to the collapse was overall successful. They said evacuating the remaining attendees and getting the injured to the hospital was handled successfully.
The Commission has begun implementing changes to its severe weather and crowd control policies as a result of the two investigations.
