Dhaka: Bangladesh government officials said they hope to solve a crisis over their decision to not shut down six garment factories deemed unsafe by experts hired by western clothing brands.

Building inspectors from both sides disagreed over the safe thickness of concrete used in the factory buildings.

More than 150 clothing brands and retailers, including the world’s top fashion chains Inditex and H&M, who source out of Bangladesh, have joined the Accord for Fire and Building Safety in Bangladesh.

Safety experts hired by this group have been inspecting garment factories after a building collapse in April 2013 sparked a global outcry about Bangladesh’s $22 billion industry.

The Accord relies on the opinion of engineers from the university to determine standards of structural safety.
