Turning Rana Plaza into a nine-storied building violating the Rajuk-approved design for a six-storey structure led to its collapse causing the nations' worst industrial disaster, the country's apex body for apparel industry said Wednesday.
An investigation committee of the Bangladesh Garment Manufacturers and Exporters Association (BGMEA) has identified eight more reasons for the April 24 collapse that killed 1,131 people, mostly female workers of five garment units housed in the building.
BGMEA Vice-President SA Mannan Kochi, who led the 11-member committee formed on April 28, disclosed the findings after a two-month probe into the incident at a press briefing at BGMEA office Wednesday afternoon.
Construction of the building using substandard materials and low capacity of its pillars are two key reasons, he said.
The installation of heavy generators on the rooftop and setting up of heavy machines of the garment factories also contributed to the disaster, according to the probe report.
