Dutch officials investigating last month’s stadium collapse in the Netherlands said “essential stability components” were missing in the roof in its interim report released last week.
The Dutch Safety Board, which is investigating the cause of the accident, said the rear lateral bracing was “not fully stabilised”, which contributed to the collapse. This was identified by NCE as a likely cause of the collapse soon after the disaster.
Dutch football club FC Twente’s Grolsch Veste stadium was undergoing an expansion when the roof collapsed at one end of the stadium on 7 July during its construction, killing two and injuring a further 14 construction workers. Preliminary findings showed no deviation from the design.
Further investigations are set to focus on why the stability of the roof was compromised, how it came to be that so many workers were underneath the roof during construction and whether pressure on the roof played a role.
A full report is expected in April 2012.
