Architects' liability insurers could face a flood of claims once the official report into the collapse of Roissy-Charles de Gaulle airport in Paris is concluded.

Four people were killed when part of the terminal collapsed in May. Investigations are focusing not only on possible construction defects, but also on faulty design. If the report blames the design of the terminal, it could open the door to future claims against architects and their insurers, according to law firm Plexus Law.
