Doubts in the Ground Conditions.
Due to the tight schedule to finish the stadium in time and speed was the top priority on the construction site, supervisors went ahead with the operation to finish the roof despite several rainy days that soaked the soil and caused instability in the ground conditions. Though an visit was conducted on Thursday and civil defense official in charge mentioned that there is no obvious signs that ground was unstable though it have shifted just a few millimeters. An investigation will be carried out on the equipment itself. Investigators are looking into human or mechanical error as possible reason for the collapse.
