The expert: the Cathedral fared better than expected

Pictures from the air shows that the two large towers are still standing. It also looks like that the big structures that hold up the cultural history of the building is intact.

– We can consider Notre-Dames the main structure as the rescued, said the civil protection insatsledare Jean-Claude Gallet to reporters outside the cathedral on Tuesday.

Håkan Frantzich, fire protection engineer and a senior lecturer at Lund university, agrees when he sees the above image taken from a drone.

It also looks as if the big structures that hold up the cultural history of the building is intact.

" As far as I can judge, it looks as if the operation has saved large parts of the cathedral. It looks relatively fully disclosed, including the typical original style of eiffel that runs along with ytterdelen.

It says Håkan Frantzich, fire protection engineer and a senior lecturer at Lund university, when we show him the above picture is taken from a drone in the air.

has burned away, so it looks as if the underlying tegelvalven is the whole. Except in one place where the great spire fell down. There are today only a gaping black hole.

– the Scepter must have come up with a good speed and gone through the roof and even the vault over, " says Håkan Frantzich.

The black areas in the picture are the charred remains of the roof trusses and the roof, which burned down.

During the dark soot formation spotted the false ceiling which consists of arches and which are likely to be made of brick.

It is these arches that visitors inside the church see when they look up.

it looks as if the vaults, all except one of which the spire fell through, has taken some major damage. He believes that there are good opportunities to build new roofs and roof trusses on top of them.

– The major load-bearing parts of the cathedral looks to be rescued.

Between the towers, a wall design that looks to have been attacked by the fire because it is yellowed.

– Where it has likely been a risk that the fire would go through to the other side. Probably have prevented it by spraying water on the wall, " says Håkan Frantzich.

That so much of the cathedral has survived may be due to just this, that the firefighters also sprayed water on the parts of the building not burned.

It was probably the one that rescued the two large towers, says Håkan Frantzich.

– Including the two large bells hanging in the huge wooden structures – and which is left.

By spraying on hot surfaces vaporize the water and it steals energy from the fire, " explains Håkan Frantzich.

" Right glass is very sensitive to uneven temperature distribution. Then the tension inside the glass to make it crack. To avoid this you can spray the water directly on the glass, with a constant application of water so it does not become dry.

made to the famous rosettfönstren survived.

Håkan Frantzich don't think it looks to be any risk that any more will crumble together.

– But if there are weak parts then they can rage about it for example blowing up.

The most important thing now is to secure the front of all the arches so they don't fall down on the inside, says Frantzich. Even the scaffolding looks fragile, and must be mounted down with caution, he claims.

it has been called a arkitekttävlig who will get to draw a new kyrkospira.

the Goal of the competition is according to the French prime minister, Edouard Philippe to draw a new spire, which is adapted to today's technology and challenges.

The rooster that sat at the top of the spire have been found. It is reported to be badly damaged, but with good hopes to be able to restore it.

as to how, in the future to better protect the historical buildings. In particular, it is important to consider how to do, when they are undergoing renovation work, says Håkan Frantzich.

– in Particular, how to use certain tools as angle grinders or whatever it is.

Buildings that are being renovated are particularly vulnerable. This is because you might have to disconnect the security system to be able to work. Even walls and floors which would otherwise have a firebreak effect may need to be removed.
