The IBC mandates that all outdoor equipment and systems, especially those on rooftops, require an engineering calculation to be performed to determine the possible lateral and uplift forces. If this engineering work, which helps determine the necessary attachment methods, isn’t completed we are at risk of equipment and or buildings being damaged, or worse yet life safety issues. The Wind Loads per ACSE7-16 document that can be downloaded here provides you with information on how these calculations should be performed properly to achieve code compliance
