The flame-retardant properties of the clad concrete ceiling had to be increased and improved. To achieve this, the existing Durisol elements on the soffit were affixed to the concrete ceiling with two fire safety dowels. The seams between the elements were closed with fireproof mortar and the reinforcement segments made of steel were clad with fire protection material.
