@Dander Spat Partly agree. It's no doubt a shit-filled conspiracy cover up, but I don't think it would lead to assassination, today.

[@thedolphin5428]

@Dander Spat Lol. Yeah I get your HW reference! The more I look into this story, the more murky it becomes. There are, apparently, many levels of PR subtefuge going on here -- at the time of building (no structural overseeing, building code misinterpretation), soon after completion (Dianne Hartley's exposure), 18 years later (when the story first got out, blaming others for the cockup, NIST pretending it was all just an over-reaction), and now 45 years later, all the historical players are all spinning it differently. A sure sign of money and guilty incompetence pushing the agendas. Not a conspiracy theory, just observable facts.

[@darthvader5300]

It is not a mistake. IT IS A DELIBERATE COST SAVING MEASURE FOR THE CONTRACTORS INVOLVED TO GET THE CONSTRUCTION CONTRACT. I remember your Admiral Rickover who is the most akward customer any contractor has to face in his life for Admiral Rickover is a FANATIC WHEN IT COMES TO SAFETY QUALITY STANDARDS which he had raised many times for lives are more important than costs savings.

[@TonyRule]

@Anton Zuykov Some people really do get wrapped up in their own self importance. It's always best to have others cast their eye over designs - especially those who'll be making them. In mechanical engineering you have to consider tooling, so there's associated increased costs in specifying a process that your fabricator cannot do in-house. This can be as simple as knowing what their particular press brake is capable of in terms of the thickness of different materials. Architects have to be the worst for such dismissive behaviour.

[@AnvilDragon]

Agree, he listened. Very unusual. The Architect is considered responsible (and always right), this was the structural engineer, who is always right over a mechanical engineer, and then senior trades people that have experience actualy building things, supliers... Student? I had a hard time getting my design teacher to listen, he had a Phd and was licenced, hence always right.

When doing "one-off" or innovative design, as opposed to "tried & true" method, there is always an elevated risk factor. You don't have the luxury of other's past mistakes to guide you.

Big mistake was from public authorities to let people into building and surrounding areas immediately after finding there was a major, life threatening, estructural problem, while deciding how to deal with it, and during emergency repairing. The fact that they only worked graveyard shifts, plus making every possible effort to keep it “discrete” and hiding it, day after day, from building users and neighbors, probably extended, and for a big margin, the repairing time. One thing is to “not to create hysteria” and to “keep everything under control, calm and peaceful”, quiet another is a corporation and an Government saving their “good names”, “reputations”, careersdeliberately placing thousands of lives at risk for three long months

We would be creating more clean energy jobs, taking action to care of our environment and not eliminating environmental regulations. I believe race relations would be better, not perfect but certainly better. I also believe that the ACA would be properly funded instead of two years of efforts to dismantle it. I believe we wouldn’t have the tariff battles that have unbalanced our markets and trade hurting many Americans. We wouldn’t have had the longest government shutdown ever costing us $10 billion in the public and private sectors. And there’s more that I believe would be better had almost anyone else had won instead of trump. I don’t judge a president’s success just on the stock market, but if I were, note that the market rose 140% under Obama (8,000 to 19,800) . To just equal that market performance it would have to hit 49,000 points during trump’s tenure. While it would be great, I own stock mutuals, I highly doubt that that will happen. I’ve searched for what he’s actually accomplished that’s good for us and I can’t find much.

[@Kenionatus]

@@streetracer2321 You need to be very careful if you tell people that they're in danger. Failing high rise buildings are an especially frightening prospect. Provided that an evacuation of the area wouldn't have made more sense, I think not informing the public was the right thing. It would have caused a lot of problems with people refusing to go to work or moving out of the direct vicinity. You also shouldn't forget that stress you can't do anything to alleviate is harmful to physical and mental health. For me, the real question is whether they should have closed down the skyscraper and the neighbouring buildings. 200,000 people is a lot. Even a small chance of such a dramatic event leads to a high average number of lives lost. It might sound terribly utilitarian and cruel to express lives in money, but it's pretty much the only way to decide how much to spend on safety measures. Assuming the value of a statistical live to be 3 million dollars, the maximum damage preventable by evacuation would have been 600 billion dollars. With a 0.1% to 1% chance of failure, that results in 0.6 to 6 billion dollars worth of expected preventable loss of live. I don't really know how many people you'd need to move and how much that would cost. Let's say one million people at the cost of 3 months * 3000 dollars. That's 9 billion dollars, so it was probably a reasonable decision. I would have liked to be informed about the situation and the decision process afterwards (if I were living or working there), but given how the media and people who don't care about maths would have reacted, I can understand why they kept it a secret.

Do you let her go to work everyday in a potential death trap, just to avoid people 'refusing to go to work or moving out of the area?'

While we're at it, why not reduce the speed limit on roads to 15 km/h (9.3 mph)? You can't stop everyone from dying. There comes a point at which you have to decide how much money (or time and resources) you want to allocate to safety. In your hypothetical situation, I'd probably ask the architect why he didn't inform the public. If we wouldn't give me a sound answer, I'd inform the media myself.

But it's certainly not enough. I recommend people look also up the story behind the Ronan Point debacle in London, UK back in 1968. The cause of that was basically covered up, too. Again, the various entities involved fixed the problem in that particular building. But they kept the details under wraps. And that led to dozens of identical buildings in the UK, and hundreds of similar buildings worldwide, vulnerable. It's only in the last year or so (50 years late) that the VIRTUALLY IDENTICAL buildings in the UK are finally being retrofitted to resolve the safety issue. Fortunately none of those buildings in the UK collapsed. But they easily could have done. And many similar buildings worldwide HAVE collapsed (especially in the former USSR), sometimes with serious loss of life.

I'd much rather be sleeping in a plastic tent in a parking garage with only urinals around and portable showers and sink than being living in a building at risk of falling it took the welders 3 months to finish everything because they could only work at night you'd only put people out of there apartment for at most a month is the welders union can have people there around the clock . 8 hours a day is very minimal work when it comes to the shit they did. So 3 months is reasonable for only at night work but think how much faster this could've been fixed and don't properly. Who knows what these guys missed in the middle of the night tired as hell.

This "measurer" is just that, a measurer, not an engineer. He deserves zero respect because he gave ZERO gratitude to the Diane Hartley, the very person that likely saved his career. He spoke with her directly and after all those years, still refers to her as a "him". He claims to not know her name or what school she attended. This is all BS by a BS engineer. He deserves zero credit. He ONLY admitted fault because there was NO covering up for this. It was a grave mistake and he knew it after doing his own re-analysis. He DELIBERATELY chose to refer to her as a "him" because he couldn't accept the fact that a girl found a massive design flaw in his work. Watch his 1995 talk at MIT about this and you will see why this guy is notjing but a POS. He claims to wish 'he', Diane, would have called him back all these years. Well guess what, she did call this POS many times back but he and his firm ignored her calls because they couldn't accept the fact that a college student, a girl, had made them all look like fools. In my book, this guy should only be remembered as a measurer, not an engineer because given the gravity of his mistake, her name, her gender, and her school would be forever seared into his brain. He chose to forget everything about her. Likewise, he will forever be remembered only as the measurer who couldn't read his tape.

[@jimwerther]

Jesus, take a breath. It is an open question whether Hartley was the student to begin with. Apparently a male student beat her to the punch, according to other accounts of the story. In fact, many specifics in this video are disputed, including whether or not the architect even knew that substituted materials had been used, without which there would not have been a problem. Also the wind issue, mentioned here as 70 MPH but elsewhere as 75 MPH, is an extremely rare occurrence in NYC, despite what this video said. It is estimated at being a once per 16 year occurrence, or perhaps 55 year, or even 700 year. I don't know, but in more than 40 years of living in NYC, I sure don't remember ever having winds of 60 MPH or above. This is hardly a clear and settled matter.

[@neosozavac]

@@jimwerther I was curious about the wind speeds in NYC as I am a wind turbine tech. 60-70mph gusts happened at least three times in NYC in 2020 from what I saw on various news websites, so those conditions do not seem to be as rare as you claim. However, regardless of the likelihood of extreme wind when it was built, it doesn’t surprise me that Lameasure or whatever his name is did not give much credit to the college student that caught his mistake..majority of people in high positions such as himself are usually egotistical a-holes.

[@vangmountain]

Not clear cut and settled but you seem to make the case that she wasn't when just about every story points the fingers to Diane. She's seems to be a wonderful person by all accounts. She's never tried to claim that she "knew" this was a problem. For her, it was an inquiry to help her reconcile what were likely her shortcomings on her calculations. She wasn't looking to say, "you screwed up", but rather, to say, "please help me understand why my calculations are giving me numbers that are greater than yours." She even openly admits to NEVER haven spoken to to him directly. It's likely his recollection failed him. He likely spoke to his junior engineer, Weinstein, who spoke to LeMessurier and hence, the mistaken gender identity in his recollection. My point IS that any humble and ethical human being, after having been through such an ordeal WOULD HAVE taken the time to track down the student to thank him/her. This was no minor thing. This was a MAJOR disaster averted and the design flaws were not minor. LeMessurier and everyone involved knew this. THEY ALL OWED a debt of gratitude to "THE" student. Her questioning likely saved tens of thousands of lives and averted both a humanitarian and economic crisis. How many people would have died? How many companies would have filed for bankruptcy. How many people would have gone to jail. You seem to downplay this threat because you've lived there for 40 years and don't ever recall 70mph wind. Did you actually do any research on this? Oh yeah, that's right, your recollection is more important than actual factual data. LesMessurrier, unlike you, actually did. And THAT us why he made the decisions he did. He was FORCED to concede defeat because he KNEW the dangers were VERY,VERY real. He DID NOT want blood on his hands so he did the ONLY thing he could do--FIND A FIX AND GET IT DONE ASAP! To his credit, his original designs did call for welded connections but a request to change by Bethlehem Steel was made and approved by his firm. Unlike you, in my line of work as a design manager and lead designer for engineered components for residential and commercial buildings, I have seen structures fail catastrophically due to wind. IT HAPPENS ALL THE TIME! I have personally been out to look at and access these failures and you know what the biggest issue is? The biggest issue are people with your mentality! "It's a beuatiful day, there's no chance in hell a strong gust is gonna show up". Guess what, in the span of 15 mins, I was witness to the aftermath of a total collapse of a roof structure. A storm rolled in on a perfect day and leveled it. The builder didn't bother to brace everything properly because "it was a beatiful day" and like you, he was banking on his personal experience so he left it unbraced. Upon his return 15 mins later, his structure was on the ground. I see this over and over from people with your mentality. YOU DON'T BET LIVES on a 1/16 chance or on your personal recollections! That's what the statistical data said about how often winds of this magnitude occurred in NYC. In engineering circles, YOU DON'T GO TO THE BANK ON SUCH NUMBERS! Even 1 in 100 years, you don't sleep well on for structures of this magnitude and here you are rebuttling using your lived experience on wind conditions in NYC. When it potentially could involves tens of thousands of lives, YOU WANT BETTER A BETTER THAN 1/16 CHANCE! The wind forces acting on a structure of this size are immense! I have worked with and corrected many an engineer and architect and most are humble enough to thank you when you help them. The magnitude of this design flaw is so great that ALL parties involved SHOULD have tracked down that student and given her, AT THE VERY LEAST, a "Thank you." NO one acknowledged her contributions. As to your statement about another student beating her to it, really? Where did you get that from? The ENQUIRER? I guess "inquiring minds" like yours wants to know so instead of going with every major story that points the finger at Dianne, you'd rather go with some other version that will fit benefit your position. Really? How many engineering schools are in New Jersey? What are the odds that two students were told by their advisors to go and research this one building out of the many thousands of buildings out there? And what are the chances that they came to this same conclusion AND contacted LeMessurier's firm about? What are the odds that TWO random New Jersey undergrads did ALL of these things and the other just happened to beat Dianne to the punch? I get it...I get it! You did the math...1/16! You like those odds. Unfortunately, your odds are a bit flawed like the design of this building. With all the info available, DIANNE IS THE STUDENT, SHE IS "HE"! To paraphrase her advisor at Princeton, "I know all the engineering schools in New Jersey. I know all the heads of those departments and i contacted them all. None of them said it was one of their students. The student invquestion is you, Dianne!" Give credit where credit is due. You choose to ignore ALL THE FACTS that point to her and then back that up with what? What evidence do you have that says it wasn't she who was the one? LeMessurier's words? Like I said, he's an egotistical POS! His words don't mean a thing because he was part of a grand conspiracy to conceal this from the public eye. It's not like he openly came out about this of his own accord! It's only after he was asked directly by a reporter that he confirmed the events. HE KNEW, THERE WAS NO COVERING IT UP. Too many people knew so he had no choice but to be upfront about it. The point you don't get is, regardless of whether it was Dianne or not, given the gravity of the situation, CREDIT SHOULD HAVE BEEN GIVEN BUT IT WASN'T AND HAS NEVER BEEN GIVEN. All the big shots in the know, especiallyLeMessurier should have tracked this student down from the start! As a matter of fact, LeMessurier's firm should have offered her employment for her contribution!

Then again, buildings don't just fall down, do they...we thought

@@user-go7mc4ez1d First, you assume people lying about creating a threat to hundreds of thousands of people is then going to suddenly develop a sense of morality? At what wind speed exactly? 65mph? Second, building are worth less than humans. Even big expensive buildings. There's ZERO financial justification for essentially forcing people - hundreds of thousands - to unwilling risk their lives for someone else's "wasted resources". And I find it bizarre you think the opposite is true.

I was an engineering student working as a computer operator in this building at night when this was going on and I just found out the full truth! I distinctly remember that there was some kind of structural work going on, asking about it, and being told something like "Oh the building sways a lot in the wind, and they want to reduce that," but nothing about any failure risk. I should have been told the full story so I could decide for myself whether or not I wanted to risk my own life for the pittance I was being paid. I'm actually kinda angry about how both Citicorp and NYC officials considered my life to be expendable in the service of covering up a legal and public relations debacle.
