Why The Marble Panels Of The Grand Arch in Paris Started To Fall Out? | Massive Engineering Mistakes 

First thing comes through my mind. Paint it yellow and it looks like the national geographic logo.

The elevator looked like a scaffolding!!

The elevator shafts in the middle are breaking the clean design language

The tiles wouldn't have fallen if they had just used flex glue

The elevator shaft really ruins this thing

This video could have been 10 seconds long. Basically, the tiles absorbed water, bent, then fell off 💁🏻‍♂️.

An architectural marvel of the modern world: Behold! I give you the box!

cameraman: yeah can you just hold up some baguettes that would be lovely confused girl: sure? i don't, uhm.. 0:17

Nether Portal is supposed to made out of Obsidian not Marble...

Well, for starters, THAT isn’t even an arch.

"Chosen for its strength and simplicity".... Its a goddamn white square, I wonder how long it took the guy to come up with it.. 😂

Really thought there'd be more comments about the pronunciation of Louvre

Why am i watching this i have finals

When the older one is more durable than this nat geo logo then clearly there's a problem here!🙄

7:11 The body language of these workers says "I don't know - I think it will be OK?"

Why is it looks like its constantly under construction?

I love how we humans can just pun out stuff from thin air. "This arc just wasn't as triumphant", I mean come on we're all just a ball of goofiness.

such a great building

A rectangle. Wow. Mind blowing. Ground breaking.

Honestly, this thing would look better if they added artificial water falls and more green plants growing at the bottom or top of the building.. like really, if it's gonna look this painfully bland, at least spruce it up with some mother nature in there.

4:48 is where they start talking about the panels falling out

Similar thing happened to a couple of buildings in New Delhi where a "renowned" architect used sandstone tiles stuck with cement outside to harmonise with the sandstone used in iconic legacy buildings when New Delhi was built. Sandstone being highly porous, the tiles absorbed water, the cement bond weakened & tiles started falling off. The fix was tortorous - bolting each tile with stainless steel bolts. The legacy buildings which were built with sandstone blocks suffered no such problem & look grand even after many decades.

Am i the only one who find the design so bland and ugly??

I visited this building a few years ago. It's quite a sight to see in person. I didn't know the marble had been replaced.

Went to france with my dad just for this building when it was finished

Looks like something from Minecraft...

Will come back in twenty years for part two.

Aight so when do we activate the portal to the Nether

6:21 - Who is this random guy asking me if I can imagine being hit by a falling marble slab and then telling me i can't?

Ok, the marble absorbs water, heat drys it, will crack with time. Perfect let use it!

So they didn't wait until one slab killed a person? madness!

Please just leave out the comments by the.. experts, "Can YOU imagine being hit by a marble slab???" They're very exaggerated and the story is interesting enough by itself, it really doesn't need fluff and sensation.

Its a massive tesseract

Why didn't they just put elevators inside the legs?

Arch: Has complicated french name. Me: Is square baguette.

In San Francisco, they dropped a marble panel while building the W hotel. It crushed a fire station, luckily everyone was out, but the fire station was destroyed...

Could they not have seen this coming? The thin Carrara marble on Chicago's Aon Center (then the Standard Oil Building) had already been presenting similar problems by the time they built this.

Same thing happened on Chicago's Standard Oil building built circa 1972. By 1990 the Carrera marble facade was deemed too dangerous to retain and the entire marble exterior was replaced with a slightly thicker granite quarried in one of the Carolinas (state of) A technique of mapping out stresses, in situ, was developed at this time. Allowing for a determination to be made as to which direction to cut the massive blocks into panels so as to negate such stresses, which find relief when removed from ground. The story was that those who insisted on Carrera marble, did so against the judgement of architectural firm. The cost to replace exceeded the original cost of the building itself. Pretty sure Chicago's extreme temperature variables and humidity is a bit worse than Paris weather. Was a year of my life hanging off the side of that building as an apprentice stone setter. Could see 4 states from the 900ft top of building. And found a marked tendency in crews to leave beer cans behind the stone as they erected the original exterior.

"He didn't want an arch dedicated to French military victories" That's the hardest I've laughed in a long time

wow paris and europe is so beautiful it warms my heart

this is one of the ugliest buildings i've ever seen

I work here to Paris La Défense. Happy to see this great video, thanks you 👍🏼

This thing looks aweful. Hilarious that they couldn't even get their shit together to make the elevators look good. Modern french architecture must be complete shit compared to the old!

How did I live through the eighties and never heard of this thing?

I'll be honest... the building looks awful. I don't know why, but the design makes me feel angry.

43 seconds in and I scroll down to Daniel Evans saving the day. Thanks mate going to the hub now.

I didnt know this was made today

Most people have no clue that this building is full of ancient symbology through the use of mathematics, size, ratio's and alignments. There was a huge amount of thought and study that went into this design as well as it's placement. Remember, things like this are not done with some random design, they are done with direct intent.

It looks like this is from natgeo.

6:22 Lol that’s such a valuable insight, thanks expert

God its almost cringy to watch... ITS NOT AN ARCH! ITS A TESSERACT🤦‍♂️

What a Twist!

Wtf, why is this so long. This can easily truncated this in seconds. The tiles absorbed a lot of water, bent and they fell off.

"Can you imagine being hit by a falling marble slab? It's unthinkable!" What in insightful comment, glad they included it.

That's not a "disaster on a monumental scale", and this amazing building is getting way too much hate.. ("it's a cube".... yes?? and the Shard is a pyramid and the WTC towers were parallelepipeds and columns are cylinders..)

Funny thing, the design of the arch initially made kind of a big whistle when wind was rushing through. That's the reason for the kind of designer tarp that "hangs" in the middle (to dampen /avoid the whistle noise).

“Can you imagine get hitting by a marble slab?” Yeah it’s called goin splat

Lol, the loovra

Ever heard of flex paste? It’s new

Grand Arch in Paris: Let me show you how to make a massive engineering mistake Hard Rock Hotel New Orleans: Hold my beer

Ah, it was designed in the 80s... That's why it's so aesthetically boring. It looks like a white picture frame and the most boring business building ever built had a baby.

I’m enjoying the symbolism of the modern arch (or shall I say post modern) being more about aesthetics than functionality in terms of building something with materials that they know won’t last but no one wants to tell the emperor that he isn’t wearing any clothes.

So I walked under that thing not knowing I could get squashed ... nice

Been there allot and it’s really big

O that the elevator, i thought it was scaffolding

Teseract - the geometric 3D figure? :) just like from the movie Interstellar! :)

Why is modern architecture no comparison to old-world architecture?

The exact same thing (Carrera marble) happened in Chicago, to a building now called the Aon Center. The entire building was reclad with white granite after 20 years of freeze-thaw, costing up to 50% of the building's original construction cost. Unfortunately for the Grande Arche, the Chicago reclad (i.e. the embarrasing public awareness) happened 4 years after the arch was completed.

“Rather than celebrate Frances military victories”... LMAO 😂

Discovery Channel: A cube within a cube Normal people: Big building with a hole in it.

0:13 Umm, that's not where Paris is 🙄

France: "Lets build a gigantic marble Tesseract. What could possibly go wrong ? (Loki smiles in the background ) :)

Replace the Italian marble with FREEDOM GRANITE!!!

An office building in Toronto was clad in marble. After forty years, the marble was replaced with glass. The marble remains on the interior.

Corupt government wasting money on stupid marble building People: is this time we use a guilotine again?

Paris is without doubt the most beautiful city on earth. I've been twice and it's just a delight

I love how they celebrate all the things the local hates; Louvre, arch the triumph and everything that doesn't work well with the old architecture ..

Once i was there with my Family, there were glas planes down in the arch and my Brother straight ran into one

It's not about engineering They used chinese glue (akkma) And they didnt scratch the stone before they did They should have used mechanical fixing and Italian glue .

This is geometric sculpture for architect with its simplicity style,modern classic form and being a type of Paris landmark the defect of surface materials can be corrected easily at high cost.

When I thing of Paris I think of street painters🎨

its wall became a wind prison making it the wind to stumble back and forth the walls before it escape it sides. Amazing architecture.. and i think a monumental wind break can balance the negative wind effect of its massive shape.

"...but just as iconic" bro its a big square

This is exactly what happened with the BMO building in Toronto. My dad worked on that building

How did they actually fasten the tiles to the building?

Damn, imagine that granite contract

This series manages to be absolutely awful every time, without fail. Always too long, and yet completely vague and without detail.

And yet, IMHO, the old buidings and monuments are way more marvelous that these simplistic modern works that a 2 y.o. could make with three pieces of domino.

The title isn’t really a question. Idk why there’s a question mark.

The same reason the original marble cladding of the Standard Oil Building in Chicago lost tiles in 1970's. Someone did not read engineering mistakes during arch school.

That building clearly lacks an important component: the Guilloten

The Carrara marble is only for artistic purposes, for this kind of work you'd use Roman Travertine: it's more stable, it isn't porous and it's impervious to both fog and water.

Because it isn't an arch. It is a post and beam construct. Of course marble panels fall off.

0:27 oh yes, the only kind of person we need in a video about buildings, a physicist!

I wonder what they did with all the marble tiles after they removed them?

Dear France, you built an archless square.

This is a very ugly modern monument compared to all the other lovely Parisian monuments. No one would ever come to visit Paris to see this if this were all they had

The same thing happened with the Achmea Tower. In Leeuwarden, The Netherlands. the Tallest building in the north has a known problem with falling tiles.

Arch de triumph: You don't look so good.

Ugh, what an eyesore...a testament to humanitarian ideals indeed.
