Modern technics are still used, same with the materials. Original old wood is not available anymore.

Of course it stays that way forever. Finally the wood is burned and irretrievably destroyed! Of course, this construction remains permanent in the video!

@@WinterbergerJung89 No. That wood framework is temporary. Its purpose is to support the stone arch, before being repared. Once the stones vault being repared, then a wood framewok with appropriate wood and using same technics from the from the past era.

Yes, it MUST last 1000 years.

What you are seeing in that image probably isn't what you think it is. Theses wooden arches are located under the stone arches that remained after the fire and are there to stabilise the structure. All of that is temporary support.

@@Touch_Finger It all has to be milled by hand. There is absolutely nothing that is perfectly straight in a building that old, and especially not one that has been damaged by fire.

I think there are craftsmen milling all the lumber by hand for the roof.

burnt down or was burned down ? Suspect the latter unfortunately.

No master craftmanship was seen in this video.

I am British and I live in France, and I can tell you, unequivocally, that there are many, many artisans, here who do old fashioned work all the time. Wood, stone, porcelain, pottery, clothing, music, farm work. France is a serious country and respect quality.

All that wood bolted together is temporary...it's just to support the arched brick vaulting and will be removed eventually.

I think a lot of people here think that the wooden frames are permanent, lol .

@@rossmilner6780 yeah, my neighbour could see me building the BBQ from their house. After I had completed the arch and waited a few days for the mortar to set completely before removing the frame, he wondered how it would work with all that wood in the way without it catching fire 🙄

The Romans invented it, and we still use the same method today. Your neighbour needs help 🤣🤣🤣

Il ne s'agit pas du savoir faire des templiers. Les templiers ne connaissaient pas les lois de Newton. Visiblement, la nouvelle charpente a été conçue par des ingénieurs en utilisant les moyens de calcul actuels.

@@alain3164 mes beaux frères étaient compagnons dans la charpente ils traces parterre leurs charpente longueur largeur angles de coupe ils ne travaillent pas avec des ordinateurs et architecte ils faut leurs rendre justice compagnonnage

@@user-yk3vo9mb3v Je faisait référence à la reconstruction des charpentes et de la flèche de Notre-Dame. Je pose la question dans ce cas spécifique. Les nouvelles charpentes sont-elles identiques aux charpentes qui ont brûlé ou ont-elles été recalculées? Pour la flèche de Violet-le-Duc, c'est différent car elle date du XIX siècle. À cette époque, on connaissait les lois de Newton. On pouvait donc calculer des charpentes de façon moderne, mais sans la puissance des ordinateurs d'aujourd'hui. Notez qu'une fois qu'une charpente a été calculée, elle peut être fabriquée avec des outils d'époque. Le traçage par terre des coupes traduit alors le calcul des ingénieurs. L'habileté des compagnons pour réaliser cette coupe est alors impressionnant. Es-ce ce qui a été fait pour Notre-Dame?

La charpente sera là même puisque ils reprennent les mêmes dessins de l'ancienne flèche pour adapter chaque éléments prévus quand la croix a été mise en place le charpentier était présent je me suis aperçu que les chevilles ont été remplacé par des tige boulonner qui enlève rien là beauté de la flèche avec les ornements

@@user-yk3vo9mb3v C'est logique car la flèche a été dessinée au XIXième siècle par Viollet-le-Duc en calculant les forces dans chaque élément de façon moderne. Pour ce qui est du reste de la charpente du moyen-age, il est certainement possible de l'optimiser.

"New " technology was used way back then. It took many decades of work to construct these buildings. Things evolved during the construction. I don't think that one single mason or carpenter particularly relished working 200 feet above the streets with no protection of any sort. Of they would have had the same tools/techniques that are available today, they would have used them. It was not done as some romantic gesture. It was dirty, dangerous and brutal. They would have loved to have had chain mortisers, chop saws, electric winches........,...

@@catabaticanabatic3800 The old technology they had back then was completely different to the new of today. Different steel, different fasteners, different tools, different wood, different concrete, different plaster, different paint. There is just different everything. Many practices are very similar or virtually the same, but that's about it.

The 3D scan done prior to the damage was invaluable to the reconstruction

What you are looking at is not what will replace the old roof structure. All this "new timber" you see is just to provide support for the reconstruction of the stone vaults. It will be taken apart and removed once the vaults are repaired. The cathedral actual timber framing is being re-done the same way it was done 800 years ago, with hand hewn timber and with the same workmanship as the original. Old workmanship is not lost at all.

It's just here to hold the stone during reconstruction and will be taken down later

The new timber framing for the roof and the steeple are identical to the ones that burned. Is not what you are looking at in the video. It's only the supports for the reconstruction of the damaged stone vaults. It will be removed once the vaults are repaired.

But are they going to leave the OSB flooring in or remove it once they are finished?

Avec une cage à écureuil.

Yes, a lot of people commenting seem to think that what they see on the picture is the actual timber framing of the roof when it's just a temporary support for the reconstruction of the damaged stone vaults.

@@CH-tn3fn actually, these supports were installed under the entire vaulted ceiling. Except for the transept. That was left open for the major work to be completed. The supports will need to be constructed for the transept so the vaulting ribs can be installed, as this was the area that completely destroyed when the spire collapsed. The thumbnail only shows theses temporary supports under the vaulting of the apse. Once the main vaulting arches are finished in the transept,then it will still need to have the infill blocks created. Only then can the temporary supports be carefully removed. As there is the chance that due to the weakening of the transept columns the entire thing could collapse again. As fa4 as I have seen, there has been no provision to permanently secure these columns from moving, even with the multi ton weight of the spire framework that has been installed. Most people have only recognized that they desired to have an exact replica of the original constructed and have given no consideration to what would actually be necessary to insure no further damage. This roof was never and will never be seen by any of the public, so any additions to secure the walls for the future, will never be seen, if above the ceiling.

They called the wooden structure supporting the roof 'the forest'. Yeah, no wonder it burned... 😢

It's hardly going to be all steel and in that fire steel would have collapsed aswell with the heat

​@@djhago3123Tho if it was steel, it would be nothing to burn🤷‍♂️

@thealaris rarely find all steel in a 800 years old building

This structure is magnificient but temporaly... just to keep the building safe during the restoration. So wood treatment isn't much a matter in that case... it won't last longer than 3-4 years.

It defenitely is, especially after accident like that

Not a single one !

I do hope they install sprinklers, even though they are ugly to look at.

And what's wrong with those? If we have modern tech that can make it better why wouldn't we use it, especially when original roof structure already had metal braces in it

👎👎👎👎👎👎👎👎👎👎👎👎👎👎👎👎👎👎👎

@Nicole-fdco60 Can not burn anymore.

Steel is to heavy, and they rebuild it with original methods to keep it authentic, so the wood was obvious choise, especially now, when we have special treatments that can protect wood from burning, so we're able to build skyscrapers with it

@thealaris Steel is not too heavy. There are some examples of that.

Occupez vous de votre pays. Trolleur.

As many trees as necessary. I suppose your home contains no wood.

It is estimated they need between 1000-1500 depending on their size as they need 2000 m³ of wood. They have scoured the French countryside looking for suitable trees that are as old as possible. I worked on a job in York where a 14th century beam needed replacing, they found one in a wood yard in Boston which was checked for age, shipped to York, where they removed the old one and carpenters painstakingly carved it identically to the original with adze to replicate the original cuts. This would not be possible with Notre Dame as there are few trees that old but and not many 1800's wooden beams lying around. It is better they build it with wood that is mostly the same age as it will dry and season at a similar rate.

Thanks for that. Most interesting.

Steel will rust.

The twin towers of the world trade center where made of steel. It didn't save them.

@jonathanlanglois2742 I don’t think that’s correct , they are rebuilding the original wooden structure.

@@Touch_Finger Take a closer look at the video. Theses arches are temporary falsework in order to stabilise the structure. The wooden roof that you are talking about is above the stone vault. Note the windows. They tell you exactly where this is in the church. This is above the choir. There are no windows in the roof itself.

@jonathanlanglois2742 Yep, I guess you’re right

hahahaha! youre so funny. while I agree it is a waste of money to build another pagan temple to the fake virgin mary sun goddess, you WILL face God VERY soon. this world is all but done and your time is almost up. so funny you people wont believe in God but you believe that the universe, earth and life just poofed into existence without any cause whatsoever except chance...big bang, abiogenesis and evolution require much more faith than I have....congrats, you certainly have more FAITH than any Christian to believe in the unproven and unprovable fairy tale called evolution.
