Charles de Gaulle airport operator Aeroports de Paris was this week contemplating demolition of its newest flagship building.
The stricken terminal handles some 15% of the airport's passengers and was designed to take the Airbus A380 'super jumbo'.
'It's too early to say, but you can't exclude the possibility that the building will have to be demolished, ' said Charles de Gaulle executive manager Rene Brun.
'We have three plans: open one part of the building within the next three months; open the whole building after thorough checks in perhaps six months time; or never operate it again.
'If required we will destroy it, ' added the airport's deputy operations director Francois Charritat.
UK structural engineers told NCE that full demolition might be the only option.
'If this collapse was the result of a systemic problem demolition may be the only realistic option for ADP, ' said Atkins head of structural engineering Mike Otlet.
But WSP group technical director Stuart Alexander said that if the cause of failure can be identified it should be possible to design a remedial solution.
'The airport's already carried out one programme of works to rectify weaknesses in the column heads. There's no reason why they can't go back and do more, ' he said.
The French government has ordered a judicial investigation into the collapse.
Paris-based consultants contacted by NCE said it was imperative that results of the inquiry were published quickly.
