Issa Knife theoretically a lot of buildings are designed to take that including the new WTC we just haven’t seen it. In a way the design of the towers did contribute to their collapse.
Issa Knife no one said it was the buildings fault they collapsed just said the facts that the unique design of the towers was partly why they had collapsed so quickly, trapped so many people inside, and caused a chain collapse.
It is probably because of 9/11 that we now think of designing stronger buildings so that if that were to happen again the damage would be less than that of the twin towers (the towers were designed just fine, they just weren’t design to take a hit by an aircraft, the possibility of that happening was just unthinkable, and the building systems continue to evolve every year, the towers design was great for its time, and now we learn from experience)
I'm halfway through and realized he's doing this in one take, including the intro!Way to have your thoughts together for 10 min straight! I can't keep my thoughts straight for 30 seconds.
Have a look at "Vancouver House" in Vancouver BC Canada Roger. Looks soooooo cool, but if the earth decides to shake things up a little (or a lot I suppose) what then?
@@JunkCult I hear you, but I actually look forward to crossing that bridge. That silhouette from up close is mesmerizing. They did a similar building in Calgary (I think) that's the opposite; tapers from the top. It's not nearly as impressive.
The best part here is the fact that the engineer listened to the student, rather than ignoring them because he is experienced and the student isnt. Kudos to William for that!
the student that LeMessurier did talk to didn't have any issues with the construction - he was Lee DeCarolis who was a 1st year architecture student - he just wanted to know how it stayed up - his professor had been skeptical of the buildings design the one mistakenly assumed to be the student he spoke to was Diane Hartley - who wrote her bachelors thesis on the building - and she was worried about the wind loads and the placement of the columns - the engineer she spoke to explained why that wasn't an issue - she didn't understand the engineer - but cuz she mentioned the quartering winds - it is assumed she got it right - and in a sense she did - cuz LeMessurier would recalc the wind loads after his convo with DeCarolis - and determine the quartering winds were more of a threat than the perpendicular winds - due to the bolted joints in the chevron supports well - it appears they were both wrong - recent analysis of the wind loads using modern technology has determined that the quartering winds were not quite the threat - it could be the building was never in danger of collapse in a high wind - but it will take an analysis of the original design structure to determine that
@@johneyon5257 Stop spreading lies Yes, today's data does reinforce that the Citicorp (now Citigroup) skyscraper in New York City was at serious risk of collapse due to structural vulnerabilities when it was originally built in the 1970s. The risk was first discovered in 1978, just a year after its completion, when a young structural engineer, Diane Hartley, raised concerns that initiated a re-evaluation of the building's design. The Citicorp skyscraper, at 601 Lexington Avenue, was unique due to its stilt-like design. Architect William LeMessurier positioned four massive stilts at the center of each side, rather than at the corners, to accommodate an existing church and create a striking visual effect. However, this left the building more vulnerable to certain types of wind loads, particularly quartering winds (winds that hit the building at a 45-degree angle). Additionally, a crucial change in the structural design-a shift from welded to bolted joints to save on costs-made the building even less stable under certain wind conditions. It was later discovered that these bolted joints wouldn't hold under the severe wind loads New York occasionally experiences. If an intense enough storm had hit the building, there was a real chance of collapse. It was only through a quiet and urgent retrofit, where the bolted joints were replaced with welded joints, that the building was saved from this risk. The work was conducted at night and completed in secret to avoid public panic. Today, advances in computational modeling, structural analysis, and wind load testing confirm the initial analysis that the building was vulnerable. Modern simulations and load assessments have shown that, without the retrofitting, the Citicorp Center indeed could have experienced a catastrophic failure under certain wind conditions.
Props to the original designer who was open to thought that maybe his building was unsafe. He’s a great example of a critical thinker. He doesn’t dismiss other people’s opinions or thoughts just because they aren’t the same as his, instead he tries to see where that person may be coming from so he can correct his mistake or help the other person correct theirs.
in a way - in this case - in talking to Lee DeCarolis (now an architect in NJ) - he described how the structure was robust due to the V bracing that directed the weight (and wind loads) to the columns - it got him to rethinking about the wind loads - and he recalculated unfortunately - he didn't remember the student's name and begged him to contact him - but he died before DeCarolis read about LeMessurier's escapade - and DeCarolis was evidently reluctant to reveal himself cuz it would like he was claiming to be a hero - so after the NIST re-analysis of the wind loads which says that they were not the severe threat that spurred LeMessurier to get the building reinforced - and the building may not have toppled in high winds as thought - he felt safe to tell his story (see OnlineEthics (dot) org and search for his name) there's a reason this building is discussed in talks of ethics - cuz LeMessurier immediately tried to assess the building's strength based on his new calcs - and when it was deemed unfit - he approached the bank - and even the city was brought it - paranoidal people want to criticize everyone - but in fact - the response by everyone was exemplary ironically - it may have been wasted - recent analysis of the wind loads using modern technology says that the quartering wind loads were not the threat that was assumed in 1978 - maybe the original building would have held up

To clarify on the history of buildings that fell. I do realize that WTC fell. I meant to say "topple in an unplanned manner". While one of the World Trade Center building almost did topple, it didn't actually crash directly into other buildings. This would have been the only skyscraper in NYC history thus far to have toppled onto other skyscrapers.
I think what he’s saying is in a domino like fashion. But they did destroy all the low rise buildings surrounding them including the 22 story Marriot hotel between the giants. Also damaged other larger towers pretty badly including 7 WTC which ended up also collapsing that evening. Just a terrible day. Never forget 🇺🇸

99% Invisible (a design oriented podcast) has an episode on this tower and even interviews the student, her name is Diane Hartley and according to her Twitter she's a 'Real Estate and Business Development Consultant'.
Yes, Robert. His cadence is broken and difficult to engage with. There is tons of dead air which is verboten in broadcast reporting. I was in a constant state of anticipation like, “What has happened to the audio?” I’m hopeful he’ll improve too. He has a nice style.
It's worth mentioning that LeMussurier had calculated that with the tuned dampener functioning it reduced the building sway by 50% so it should be able to withstand Ella but it needed electricity to operate and if the hurricane knocked out the power then the building was doomed. That day they installed backup generators to keep the dampener working no matter what. LeMussurier wasn't just appalled that the developer switched to bolts but also how few they used. They wound up welding extra 2" plates over the joints. Cost Citicorp $8 million to do the complete fix. They sued LeMussurier because it was his design flaw. With no lawyers LeMussurier and some VP from Citicorp worked out a settlement in which Citicorp accepted the $2 million LeMussurier's insurance company would pay on the claim and absolved him from further indemnity.
I didn’t use a script. All of my one-take videos and live-videos are unscripted, I just research and tell the story spontaneously ;) I’m glad you enjoyed it!
Urbanist: Exploring Cities aw that’s nice I love how natural this is and people are complaining about the pauses but I find them relaxing and like how this is so spontaneous 😊
The “Tour du Midi” in Brussels is even more extreme. It balances on a huge central and smaller column that holds up the entire skycraper like a christmas tree.
@@faii1660 True. So many people either talk so slow or they keep stalling to make that 10 minute deadline. Many of these videos could be 4 minutes, but it has to be stretched. Thank Jesus Christ many other UA-camrs made videos on this.
Oh, really? How about the thousands of people that were are risk - and told NOTHING by the authorities or the engineers and developers? How convenient that the newspapers were - conveniently - on strike during the clandestine repair period? Was that engineered by the city authorities in collusion with the involved parties soley for their self-interest - but with total disregard for the citizens right to know? That is the very definition of high-level corruption
Legend has it that Diane Hartley an engineering student at Princeton found out about the weak bolted joints as the engineer was out by 40% it was her critical analysis that exposed the problem that was fixed at night so the public would not know!!!!
Since you state that the student called Le Messurier on the phone because Le Messurier said a student called him, you obviously assume he made a mistake in saying the student was a “he” since you don’t mention it. If you had listened to Diane Hartley, she did not talk to Le Messurier, but an assistant, which is most likely why Le Messurier said the student was a “he” who he talked to and is why he probably didn’t remember anything about the student. This would make more sense that he talked to his assistant about the phone call from Diane and mixed up the actual details of the call over ten years later when he recounted how he learned of the conclusions of her calculations. Just saying since your making a record of what happened for history and not just for entertainment.
I think you are being far too generous. It is outrageous to think that LeMessurier didn't take the time after all was said and done to find this student and give whoever it was, proper credit where it was due. My guess is, he knew full well who it was, and worse still, that it was a woman that pointed out his failure. I watched LeMessurier tell his story and it was clear to me that he was very much 'old school'. As a female engineer myself, I still experience this kind of sexism in this day and age, I can only imagine how much worse it would have been in the 70s and 80s when all this went down. Either way, shame on him for not finding the student to thank or credit, or for knowing, and still not giving credit. It would have been very easy for him to do once the story was out.
@@carolynh3437 what was worse is that citicorp at the time re-neged on a stipend of $10,000 to publish a book about the building derived from her thesis that they promised her after her studies
I worked there in the early 90s as a temp mailroom clerk, and in the early 2000s as a union carpenter installing furniture The actual address is 153 East 53rd St and it's on Lexington between East 53rd St and East 54th Street
We all remember when this building was being built. I'd pass it everyday back in 1977-78. It was unbelievable to see it on stilts, yet they made it work
I agree, I don't mind the conversational pace or the pauses to show the site (as others seem to be complaining about), but it's vlog-type pieces like these that demonstrate why the craft of editing is so important. Hire a cameraman, take B-roll, let the narrator just narrate instead of multi-tasking the whole thing, and finally cut the whole thing together properly.
You may want to reconsider your opening monologue. “Wondering what would happen if a skyscraper fell and fortunately NYC never experienced this”…. Are you for real man? Has everyone forgotten 2001 already?
I love how he talks and explains it. As a someone who’s English is not the first language I have time to listen to him in peace and actually think about it and understand what he just said without having to rewind the video couple of times because I didn’t understood the first time what he just said
@Raven De Vera Yes, but that's not what he said. 😂😂 I knew exactly what he meant but it didn't stop me from cringing and ultimately laughing at his poor wording.
These kind of buildings freak me out. I get queasy walking under them and looking up. Like the Rainier Tower in Seattle. It doesn't have the outrigger columns.
A lawyer I knew said she was told she'd always be juggling multiple balls in the air. She would inevitably drop a ball every now and then; just pray and take care you don't drop the exploding ball. Really close call here.
This story is mentioned in the book, The Checklist Manifesto, by Atul Gawande. He uses it as an example of why regularly scheduled intra-team meetings are important for complicated projects. He considers those meetings to be a type of checklist and its likely the dangerous construction error would not have occurred ( using bolts instead of welding) if those types of meetings were taking place while the building was being constructed. That is not the building's (Citicorp Building) only error. It's slanted roof was supposed to be used for solar panels but was designed in the wrong direction.
the bolts were not dangerous when first introduced - LeMessurier had no problem with them when he heard about them - it was after recalculating the wind loads - he realized that they were below the strength needed however - a NIST reanalysis of wind loads says that the quartering winds were not the threat LeMessurier calculated - maybe the building would have withstood the high winds without reinforcement - but someone will have to reanalyze the original structure in light of the new wind load data
Great story, but the suspense was literally killing me 😂😂... I was like "TELL ME!!!!! I MUST KNOW!!! WHY MUST I ENDURE THIS PLAGUE OF IGNORANCE???? I MUST KNOW!! TELL ME!!"
I've stared at that building when I've been in Manhattan, and wondered the same. There just doesn't seem to be enough stuff on the bottom to keep the rest of the building up. Anyway, I'm not an architect or structural engineer, so what to I know. :)
People knew. I was in high school working part time at Herman's world of sporting goods on 53rd & 3rd. We were warned of the potential collapse of the new CitiCorp head quarters, which is the building you're discussing. They put in the top of the building a weighted counter balance which swings in the opposite direction of the sway of the bldg helping to maintain its balance.
The building does not have a look of permanence about it . I have been inside it, and even attended concerts in the church, and I'm admitting for the first tine: I was never 100% at ease. It takes a lot of hubris to tempt fate on this scale. Remember the Colossus of Rhodes?
This video is a prime example of why people need to use scripts and voiceover narration in videos. This guy sounds like he’s just making it all up as he goes along, but losing his train of thought every few words. It’s just unwatchable.
Fantastic! A great example of how the city is a sum of that happens in. This history is abiu engineering, urbanism, security, journalism, ethics and...life! Thanks to bring it to us!
the student who LeMessurier spoke to was Lee DeCarolis - in describing how the structure worked - LeMessurier was prompted to recalculate the wind loads - a NIST reanalysis now says the quartering wind loads weren't the threat the LeMessurier thought
9/11 didn’t fall over it was flown into and destroyed the integrity of the building causing to collapse. This video is based on architecture and engineering and if any building built have collapsed ON THEIR OWN. This building is one of the only buildings in NY that was going to collapse and destroy that region of NY.
I love photographing that building when I’m in that area. And I love this story you provided! I never knew. Thank god for that girl and thank god that man listened to her lol!
Yeah, today it takes only 1 worker with a cellphone and a selfie attitude to make this blow up like a crap bomb. I bet there would be several victims because of the caused paranoia.
This is just such a stupid design. Why even build like this - on the edge of disaster. Okay the church, but still. This is an ego gone wild in an engineering pissing match.
fixing it was the right thing to do but keeping the whole thing secret was not. what if it had fallen. they were just protecting themselves, not the public, by hiding that.
I'm sure there is a video somewhere explaining this better than i can, but this is the core of it: they needed the people inside the building since they acted as a "counter" to the wind.
the building wasn't going to fall at any random moment - it was going to fall during high winds (it was thought) - like in the hurricane that was coming the east coast while the reinforcement was going on - but the Red Cross and City had planned to evacuate the building and surrounding buildings should it strike - of course - it veered off however - it may not have - recent reanalysis using modern technology has shown that the quartering wind loads were not the threat that LeMessurier had determined - maybe there was never a risk of imminent collapse
I don't understand why people are complaining about the speed he speaks at... I think it's just fine, considering he's telling a story and at the same time is showing parts of the structure that's related to the story. If you want to get this information quicker then google the story and read as fast as you want :)
I love engineering and have heard faster talkers tell the tale. This was like being there. (By the way just try talking calmly on any subject extemporaneously at any busy New York boulevard)

I thought it wasn’t so good his narrating eloquence is terrible. Felt like he was biting his tongue half the time.
robert lautner yeah i agree, but seems like a newer channel, im sure he’ll improve
Hopefully hired immediately
Yes, Robert. His cadence is broken and difficult to engage with. There is tons of dead air which is verboten in broadcast reporting. I was in a constant state of anticipation like, “What has happened to the audio?” I’m hopeful he’ll improve too. He has a nice style.
It's worth mentioning that LeMussurier had calculated that with the tuned dampener functioning it reduced the building sway by 50% so it should be able to withstand Ella but it needed electricity to operate and if the hurricane knocked out the power then the building was doomed. That day they installed backup generators to keep the dampener working no matter what. LeMussurier wasn't just appalled that the developer switched to bolts but also how few they used. They wound up welding extra 2" plates over the joints. Cost Citicorp $8 million to do the complete fix. They sued LeMussurier because it was his design flaw. With no lawyers LeMussurier and some VP from Citicorp worked out a settlement in which Citicorp accepted the $2 million LeMussurier's insurance company would pay on the claim and absolved him from further indemnity.
Wow, it’s sad to see some companies cut costs at any opportunity:/
How was it his flaw they did not follow his plans they switched to bolts so how was that his fault?
@@Denvermorgan2000 depends on contract structure
Was about to point this out.
The company I used to work is at 30th floor. Watching this video gave me chills.
Were u ever scared of the building ?
All of the comments saying that you’re speaking too slowly don’t realize you’re doing this video in one take. Good on you.
I’m just impressed that he memorized the scripts and didn’t mess up
I didn’t use a script. All of my one-take videos and live-videos are unscripted, I just research and tell the story spontaneously ;) I’m glad you enjoyed it!
Urbanist: Exploring Cities aw that’s nice I love how natural this is and people are complaining about the pauses but I find them relaxing and like how this is so spontaneous 😊
building 7 has left the chat
hahaha for real
All for oil 🙃
well to be fair it collapsed from fire and didnt really collapse on other buildings
Did it fall over like a domino?
Blue9 MultiMedia Group no it collapsed itself from fire
The “Tour du Midi” in Brussels is even more extreme. It balances on a huge central and smaller column that holds up the entire skycraper like a christmas tree.
How about Rainier Tower in Seattle. That one’s on a single column that looks like it’s designed to fail
Speaking slow is way better and relaxing
Idk what the other fools talking about
agreed :) many people are too much in a hurry nowadays. That's why many popular vlogs are so manically edited.
he did it for the money
Yeah. For them, a UA-cam video will be disqualified if it fails to keep their mind busy.
@@flamixin tbh your right lol
@@faii1660 True. So many people either talk so slow or they keep stalling to make that 10 minute deadline. Many of these videos could be 4 minutes, but it has to be stretched. Thank Jesus Christ many other UA-camrs made videos on this.
Happy to hear that the designer was not full of himself and actually looked in to student’s questions
Oh, really?
How about the thousands of people that were are risk - and told NOTHING by the authorities or the engineers and developers?
How convenient that the newspapers were - conveniently - on strike during the clandestine repair period?
Was that engineered by the city authorities in collusion with the involved parties soley for their self-interest - but with total disregard for the citizens right to know?
That is the very definition of high-level corruption
That’s a major screw up... They erected a ticking time bomb in midtown Manhattan. Thank god someone realized the fatal flaw.
Not really, the major screw up would have been not to make any verification and let the tragedy happen
Imagine if it was Trump Tower. Nothing would have been done to fix the problem
Legend has it that Diane Hartley an engineering student at Princeton found out about the weak bolted joints as the engineer was out by 40% it was her critical analysis that exposed the problem that was fixed at night so the public would not know!!!!
@@joesimon2018 Son, Trumps gone. Stop wasting your life worrying yourself sick about him. Go try to enjoy life.
Since you state that the student called Le Messurier on the phone because Le Messurier said a student called him, you obviously assume he made a mistake in saying the student was a “he” since you don’t mention it. If you had listened to Diane Hartley, she did not talk to Le Messurier, but an assistant, which is most likely why Le Messurier said the student was a “he” who he talked to and is why he probably didn’t remember anything about the student. This would make more sense that he talked to his assistant about the phone call from Diane and mixed up the actual details of the call over ten years later when he recounted how he learned of the conclusions of her calculations. Just saying since your making a record of what happened for history and not just for entertainment.
I think you are being far too generous. It is outrageous to think that LeMessurier didn't take the time after all was said and done to find this student and give whoever it was, proper credit where it was due. My guess is, he knew full well who it was, and worse still, that it was a woman that pointed out his failure. I watched LeMessurier tell his story and it was clear to me that he was very much 'old school'. As a female engineer myself, I still experience this kind of sexism in this day and age, I can only imagine how much worse it would have been in the 70s and 80s when all this went down. Either way, shame on him for not finding the student to thank or credit, or for knowing, and still not giving credit. It would have been very easy for him to do once the story was out.
@@carolynh3437 what was worse is that citicorp at the time re-neged on a stipend of $10,000 to publish a book about the building derived from her thesis that they promised her after her studies
@@carolynh3437 I agree with you. I've heard this story before and wondered why she did not get proper recognition for saving a potential disaster.
Welding vs bolting makes a massive difference. You torque down a bolt all you want it will never be as strong as a weld.
Having a cigarette while talking about this would have added character. Lovely voice to listen to
Ha! Sounds very film noir, I like that idea
I worked there in the early 90s as a temp mailroom clerk, and in the early 2000s as a union carpenter installing furniture
The actual address is 153 East 53rd St and it's on Lexington between East 53rd St and East 54th Street
"Well luckily New York City never had to experience that..."
Twin Towers: Am I a joke to you
He meant skycraper collapses due to design flaws in them, not terrorist attacks.
Those are intentional, accidents aren’t.
I had this same issue in the first 18 seconds.
@@alvarodm well you do know it's a joke right
Twin towers were away from other buildings and they went straight down not tooling over
@@alvarodm R/woooosh
We all remember when this building was being built. I'd pass it everyday back in 1977-78. It was unbelievable to see it on stilts, yet they made it work
I really love that your not doing a voice over and you are there in person talking about it. Subscribed!
Yes!! Most of my videos are done actually visiting places :D there’s plenty of voice over videos out there in the world anyway
Great storytelling - That said, your videos would be greatly enhanced with tighter cuts instead of one continuous shot.
I agree, I don't mind the conversational pace or the pauses to show the site (as others seem to be complaining about), but it's vlog-type pieces like these that demonstrate why the craft of editing is so important. Hire a cameraman, take B-roll, let the narrator just narrate instead of multi-tasking the whole thing, and finally cut the whole thing together properly.
no thanks. i like his style. its nice and chill.
Check out the Millenium Tower in San Francisco. It is a leaning tower that can topple at any time and its foundation is built on quicksand
You may want to reconsider your opening monologue. “Wondering what would happen if a skyscraper fell and fortunately NYC never experienced this”…. Are you for real man? Has everyone forgotten 2001 already?
Pretty sure two skyscrapers fell in 2001…
I love how he talks and explains it. As a someone who’s English is not the first language I have time to listen to him in peace and actually think about it and understand what he just said without having to rewind the video couple of times because I didn’t understood the first time what he just said
No cuts or edits the whole time - I really like that!! Keep it up!!
Agreed, that is very hard to do.
Y’all give the dude a break... yea it was rough but by engineer standards his presentation skills are superb.
You could fit a building in between those pauses ... good god lol love the video tho
Luckily NY never had a Skyscraper fall!!!👀
@@syissa92 Yeah 7 buildings fell that day. Also damaging the millennium Hilton!!!
@Raven De Vera Yes, but that's not what he said. 😂😂 I knew exactly what he meant but it didn't stop me from cringing and ultimately laughing at his poor wording.
Amazing video! Kudos for shooting this all in one take like this! Impressive
Am I the only one that finds his way of speech soothing?
This was good man I know it’s hard talking to camera. Great job
thank you! glad you enjoyed :D
He never explained why the building was in such eminent danger of collapse other than bolted vs welded.
These kind of buildings freak me out. I get queasy walking under them and looking up. Like the Rainier Tower in Seattle. It doesn't have the outrigger columns.
0:14 this dude is living in another dimension pparently...
A lawyer I knew said she was told she'd always be juggling multiple balls in the air. She would inevitably drop a ball every now and then; just pray and take care you don't drop the exploding ball. Really close call here.
This story is mentioned in the book, The Checklist Manifesto, by Atul Gawande. He uses it as an example of why regularly scheduled intra-team meetings are important for complicated projects. He considers those meetings to be a type of checklist and its likely the dangerous construction error would not have occurred ( using bolts instead of welding) if those types of meetings were taking place while the building was being constructed.
That is not the building's (Citicorp Building) only error. It's slanted roof was supposed to be used for solar panels but was designed in the wrong direction.
the bolts were not dangerous when first introduced - LeMessurier had no problem with them when he heard about them - it was after recalculating the wind loads - he realized that they were below the strength needed
however - a NIST reanalysis of wind loads says that the quartering winds were not the threat LeMessurier calculated - maybe the building would have withstood the high winds without reinforcement - but someone will have to reanalyze the original structure in light of the new wind load data
Fascinating story. I liked the way you presented it: suspenseful till the very end!
I’m so glad you enjoyed this story!
Great story, but the suspense was literally killing me 😂😂... I was like "TELL ME!!!!! I MUST KNOW!!! WHY MUST I ENDURE THIS PLAGUE OF IGNORANCE???? I MUST KNOW!! TELL ME!!"
I've stared at that building when I've been in Manhattan, and wondered the same. There just doesn't seem to be enough stuff on the bottom to keep the rest of the building up. Anyway, I'm not an architect or structural engineer, so what to I know. :)
“Not every person in New York City ever had to experience that”
9/11: *am I a joke to you?*
Is it funny to you because you feel like it could never happen to you?
Pretty sure NYC experienced three high-rise collapses.
People knew. I was in high school working part time at Herman's world of sporting goods on 53rd & 3rd. We were warned of the potential collapse of the new CitiCorp head quarters, which is the building you're discussing. They put in the top of the building a weighted counter balance which swings in the opposite direction of the sway of the bldg helping to maintain its balance.
The building does not have a look of permanence about it . I have been inside it, and even attended concerts in the church, and I'm admitting for the first tine: I was never 100% at ease. It takes a lot of hubris to tempt fate on this scale. Remember the Colossus of Rhodes?
Good video, but could use some B-Roll
This video is a prime example of why people need to use scripts and voiceover narration in videos. This guy sounds like he’s just making it all up as he goes along, but losing his train of thought every few words. It’s just unwatchable.
In NYC skyscrapers don't fall, they collapse!
19 years later people still don't know why.
I’m pretty sure i do.
tall32guy “still don’t know why”
Fantastic! A great example of how the city is a sum of that happens in. This history is abiu engineering, urbanism, security, journalism, ethics and...life! Thanks to bring it to us!
"Luckily New York City never had to experience that"....awkward silence.
Pausing at 50 seconds, This place is not on 59th and Lexington. Okay, continuing on now.
I enjoy the slower cadance it gives me a chance to process his words.
yay! that's wonderful to hear :)
They did not need to remove any structural parts instead the already bolted parts were additionally welded together .
Great video! This skyscraper looks horrific to me😳 as a German I am not used to high buildings and I think I will never get used to them haha.
Um bro where were you on 9/11 ? "luckily New York never experienced that"
He's Gen Z he probably wasn't even alive when that happened.
Excellent story telling, maintained technical soundness while keeping me in suspense.
I’m so glad you appreciate my storytelling 😁🙌 thanks for watching!
Mans has mastered talking at .50 speed
New York thanks you Diane Hartley! 👍🏼👍🏼🤗
the student who LeMessurier spoke to was Lee DeCarolis - in describing how the structure worked - LeMessurier was prompted to recalculate the wind loads - a NIST reanalysis now says the quartering wind loads weren't the threat the LeMessurier thought
Actually, skyscrapers have fallen in NYC.
Check out September 11, 2001.
It was quite incredible how it all happened.
Remember my uncle❤
Never had to experience that? How about 9/11
This isn’t intended as a joke.
He isn’t a true New Yorker.
9/11 didn’t fall over it was flown into and destroyed the integrity of the building causing to collapse. This video is based on architecture and engineering and if any building built have collapsed ON THEIR OWN. This building is one of the only buildings in NY that was going to collapse and destroy that region of NY.
Can buildings fall down in NYC? Yes! 3 of them in 2001. How you say? Demolition
Tried to watch this FIVE TIMES. The cadence of his speech kept putting me to sleep. I eventually had to give up.
I guess this guy doesn’t know about the Twin Towers falling.
0:14, pretty sure a few have
I love photographing that building when I’m in that area. And I love this story you provided! I never knew. Thank god for that girl and thank god that man listened to her lol!
I’m so happy you enjoyed this story! And yes I’m so grateful for the student 🙏
@@UrbanistExploringCities more stories like these please! I’m hooked
I think I'll stay away from skyscrapers now.
Everyone talking about them nowadays, many have dreams to be architect
Don’t go to New York then :(
They where able to do it because people knew how to keep there mouth shut back then unlike today
Yeah, today it takes only 1 worker with a cellphone and a selfie attitude to make this blow up like a crap bomb. I bet there would be several victims because of the caused paranoia.
A 70mph wind gust is nothing. But he says that would make it topple?
I think a cat 5 hurricane would blow it down
I subscribed. Every October, my city has an open house architecture event, but I will not be going this year. I am counting on you to fill the void.
ah yes
nobody in new York witnessed a building fall
or two
This is just such a stupid design. Why even build like this - on the edge of disaster. Okay the church, but still. This is an ego gone wild in an engineering pissing match.
There’s also a lot of wasted space
The specific reason was because it is on the edge of disaster, and when you can engineer it to never fall then why not?
@@micah_lee If I were to engineer it to never fall it would be a pyramid and last 2,000 years. But I get your point.
Ikr like just don't put it on stilts simple!
"Could a skyscraper fall down?" Yeah, two very big ones did 20 years ago, pal. Or did you somehow forget about that?
fixing it was the right thing to do but keeping the whole thing secret was not. what if it had fallen. they were just protecting themselves, not the public, by hiding that.
I'm sure there is a video somewhere explaining this better than i can, but this is the core of it: they needed the people inside the building since they acted as a "counter" to the wind.
the building wasn't going to fall at any random moment - it was going to fall during high winds (it was thought) - like in the hurricane that was coming the east coast while the reinforcement was going on - but the Red Cross and City had planned to evacuate the building and surrounding buildings should it strike - of course - it veered off
however - it may not have - recent reanalysis using modern technology has shown that the quartering wind loads were not the threat that LeMessurier had determined - maybe there was never a risk of imminent collapse
“Luckily NYC never had to experience that” ummm cough cough 911 cough cough
I don't understand why people are complaining about the speed he speaks at... I think it's just fine, considering he's telling a story and at the same time is showing parts of the structure that's related to the story. If you want to get this information quicker then google the story and read as fast as you want :)
The intro in this video didnt age well
That is strangest building
Hey man what's up from Houston Texas love the video's this is a good1!
Let the guy speak how he speaks, we would never know if he is struggling with speech difficulties or not. Cut him some slack
I love engineering and have heard faster talkers tell the tale. This was like being there. (By the way just try talking calmly on any subject extemporaneously at any busy New York boulevard)
Never happened??!!! September 11th? Remember that? The day when two gigantic sky scrapers, ya know, fucking fell?!
Loved this one! Keep it going! :-)
I actually like the way you speak and find it quite enjoyable. You’re quite easy on the eyes too 😁 I too have always worried about falling skyscrapers In nyc.
Great video, nice and stable filming as well!
