If I was investigating the cause of this collapse, I would first need to gather information from the South Carolina DOB. Documents such as job filings, violations, list of inspections, and other pre-construction and current modification documents on file. From looking at the certificate of occupancy, I have gathered that due to the exceeding amount of people in the space, the floor trusses failed. The owner takes responsibility for making sure that the number of guests does not exceed the maximum occupancy.
