Leaked FEMA/ASCE Draft Report On WTC Collapse

securitas writes "The New York Times obtained a copy of the World Trade Center draft report by the Federal Emergency Management Agency and the American Society of Civil Engineers about the engineering failures that caused the towers to collapse. Among the findings: 'Fireproofing, sprinkler systems and the water supply for hoses were all disabled and the fires generated heat equivalent to the energy output of a nuclear power plant' reports the NYT (Yahoo link). Amazingly, if it wasn't for the fire (or another secondary catastrophic force), the towers would have remained standing."

Whether this speaks well of a design that can withstand a heavy impact, or whether it speaks poorly of a design that cannot withstand a kerosene fire, I don't know.

For once thing, jet fuel burns so hot that you need foam, not water, to extinguish the flames. The heat would have vaporized the water even before it would have reached the flames. Second, sprinklers are not designed to pump the amount of water that would be necessary to extinguish such a fire. They would have to deliver a flood of water (think "Towering Inferno") in order to have any chance of extinguishing the blaze. "Sprinklers" are aptly named.

      The heat from the fire caused these trusses to weaken and fail, leaving the outer steel frame without the stabilizing and load-transfering benefit.

Tree huggers say improved safety technology in cars offset lighter cars, but fact is improved safety technology in a heavier car is safer.

      Fact is had more asbestos been used in WTC, towers would have taken longer to collapse, more people would have gotten out. Asbestos was used extensively for fireproofing, but not for duration of construction due to EPA/tree huggers. Also, when the scares on asbestos first started in the 70's/80's, and corporations said get it all out (now they manage it in place and only remove when area is going to be disturbed), a contractor was hired to remove large amounts of spray on asbestos in the WTC. Most asbestos abatement contractors also are in the fireproofing business, same industry, one puts it on, one takes it off. When a company performs asbestos abatement in NYS, by law, the fireproofing/insulation must be replaced. If the abatement contractor also reinsulates, they bid the reinsulation, or they sub it. Or in some cases a reinsulation company is brought in separately. But it must be done at the conclusion of the abatement. So the contract did not specify that the NEW spray on insulation must be asbestos free. Since the abatement contractor was in the spray on insulation business, and they had just banned the MANUFACTURE of asbestos in the US, guess what type of spray on insulation the contractor had in his establishment? And guess what he sprayed back on after he removed the old asbestos? You got it. Asbestos. They couldn't do anything to him, as the contract did not specify asbestos free for the replacement. But they learned there lesson. Since then, and up until last year, there has been continued asbestos removal.

      Asbestos was in not just spray on insulation, but also plaster, floor tile, gypsum wallboard, joint compound, mastic (glue), caulking, drop ceiling panels, paint, and hundreds of other building materials. Anytime any renovation went on in the WTC, either testing was done, or previous test results were used to identify asbestos containing material (ACM), and asbestos abatement workers were used, under a long term contract, to remove the asbestos. Tons and tons of asbestos were removed over a period that continued up till last year.

      But if more spray on asbestos had been used, and more had not been removed, the steel would not have lost its strength as fast, giving everyone more time to get out. Asbestos has a melting point far in excess of 1000 degrees. Substitutes for asbestos have lower melting points.

Anyone remember high school chemistry for the resultant volume of a gallon of water that's been vapourized? Just think of ALL those thousands of gallons of water flashing to vapour in a matter of seconds... in a relatively confined space like that, I think it would have blown out major portions of the building.

      I used to teach people how to run things called Recovery Boilers. Basically, these were large metal buildings, built like pressure cookers, that can stand 200 feet tall. They have a controlled, raging inferno inside them that you dump spent chemical sludge into in order to burn away the impurities, allowing you to recover the chemicals through controlled cooling; hence the name, "Recovery Boilers". These things are HOT... damn HOT! To keep them cool (so they don't melt themselves), the walls of a recovery boiler are lined with tubes through which PURE water runs (as pure as money could make it, anyway)... no contamination or buildup was allowed to happen within these tubes. Why, you ask? If one of the tubes had a build-up of sludge in it, and the resulting pressure increase caused the tube to burst, and liquid water was injected into this raging inferno, the resulting volume increase of the flashing water would blow the whole building up. That's why they are designed with special relief valves in them that let loose should something like that happen, so that it can be a rather controlled explosion instead of having pieces parts all over the place.

      I've lived through one of these controlled explosions, and it wasn't fun. The 4 emergency relief valves acted like a monstrous pipe organ, only the frequencies were so low, and the force was so powerful, that it caused just about everyone in a 2 mile radius to feel sick to their stomachs due to the vibrations you could feel, but not hear.

      To claim that nothing can be done is just foolish. I'm not saying the engineers cut corners, far from it. The WTC was vastly stronger than any other building out there, and was really a marvel, but that was 30 years ago when it was being built. Now that this disaster has happened, it's time to learn from it. They could have never expected anything like this to happen, but here's some things that (as an armchair architect) I would guess could have helped.

      1) Try to protect the stairwells. Had the stairwells not been severed it is likely that everyone would have made it out safely, except for those who were killed in the initial blast. Perhaps encasing the stairwells in the structural elements of the building would have helped greatly, as the core structure of the building resisted the impacts very well.

      2) Try to coat the fireproofing with something that will prevent it from being easily stripped off the steel. Perhaps a layer of kevlar or strong fiberglass. This is exactly the sort of thing that modern technology has been inventing in the last 30 years. Had the fireproofing stayed on the steel it is quite likely that the towers would have stood indefinitely.

      3) If possible, use an alloy of steel with a higher melting point. Adding Tungsten might help immensely by raising the melting point from 2,000 degrees to 3,000 degrees or so. Probably way too expensive though.

      4) Rethink the trusses used to support the floors. With only minor modifications they could probably be made much more resistant to fire. Had they not failed, it is quite likely that the buildings could have stood indefinitely.

      Anyway, these are just some thoughts. I'm not quite an engineer (physicist) but I know my chemistry pretty well, and I try to keep on top of developments in structural engineering. To say that nothing could be done is kindof stupid. The towers stood for on the order of an hour, meaning they were soooooo close to surviving. A little tweaking and new buildings can probably survive a similar event.

      To say nothing could have survived that is just giving up. Tungsten melts at about 6,000 degrees, and even airplane fuel fires probably can't get nearly that hot, but that's just an example. It's unlikely that anyone could build a large structure out of tungsten, for various reasons.

      But, all things considered, the towers were exceptionally well built buildings, there's no doubt of that. However, 30 years brings a lot of revelations, especially in materials science and computer simulations.

    The things that corporations do to harm people, in this country and others, should be brought to light and should be stopped. But this is not the way to do it. If anything, the WTC attacks have just solidified the position of people like George W. Bush who make possible some of the horrors that are visited upon "starving nations." Not only have thousands of innocent people been murdered, but it's not considered impolitic to disagree with the current administration. These attacks have convinced millions of people that the only way to prevent further attacks is to give free reign to conservative assholes like Bush and Ashcroft.

Of course, the byproducts of Halon's reaction with the fire are rather nasty and toxic, but the consensus seems to be that they're no worse than the products of burning plastics and whatnot.

For Halon to work properly the space has to be sealed to the outside -- if the Halon blows away or is ventilated, oxygen is resupplied to the fire and it will almost instantly reflash(in the case of a petroleum based fire, anyway).
      Then there's the issue of the toxic byproducts --if you don't suffocate, they will kill you. Every Halon system I've seen has a mandatory time delay, coupled with klaxon horns, flashing red lights, etc... The time delay is based on the time necessary to get people out of the spaces and get the spaces sealed airtight BEFORE the Halon discharges.

Or in some cases a reinsulation company is brought in separately. But it must be done at the conclusion of the abatement. So the contract did not specify that the NEW spray on insulation must be asbestos free. Since the abatement contractor was in the spray on insulation business, and they had just banned the MANUFACTURE of asbestos in the US, guess what type of spray on insulation the contractor had in his establishment? And guess what he sprayed back on after he removed the old asbestos? You got it. Asbestos. They couldn't do anything to him, as the contract did not specify asbestos free for the replacement. But they learned there lesson. Since then, and up until last year, there has been continued asbestos removal.

    Asbestos was in not just spray on insulation, but also plaster, floor tile, gypsum wallboard, joint compound, mastic (glue), caulking, drop ceiling panels, paint, and hundreds of other building materials. Anytime any renovation went on in the WTC, either testing was done, or previous test results were used to identify asbestos containing material (ACM), and asbestos abatement workers were used, under a long term contract, to remove the asbestos. Tons and tons of asbestos were removed over a period that continued up till last year.

    But if more spray on asbestos had been used, and more had not been removed, the steel would not have lost its strength as fast, giving everyone more time to get out. Asbestos has a melting point far in excess of 1000 degrees. Substitutes for asbestos have lower melting points. Therefore, the fire rating for buildings with asbestos is higher than for buildings without asbestos. Period.

    The terrorists killed my friend Mike, fireman, my friend's wife, my aunt's maid of honor, some moving men from my old union local Teamsters 814, and they almost got my cousin, but he made it out. Asbestos may kill my uncle, who has asbestosis, and may shorten my life later on, but it possibly would have saved my friends, had they more time to get out.

      Blown off, or burned off? While some may have "blown off", most of that steel was still protected by other building materials that absorbed some of the shock before hitting the steel. Any asbestos "blown off" was minimal compared to the surface area of the steel that was exposed to the subsequent fire.

      >>There are materials which are considerably more insulating than asbestos. e.g. the materials used on the space shuttle.
      The materials that eventually REPLACED the asbestos that was originally used on the space shuttle is not more insulating than asbestos. And look at all those bottom nose tiles that fall off or are replaced after every mission because they can't withstand the heat properly.

      And look at what happened to the space shuttle when they stopped using asbestos in the O-rings of the solid fuel rocket boosters. Among a combination of factors, it was the O-ring failure that caused the explosion.

    There are a lot of issues here, but I want to address a few of them.

    1. "Spreading the Wealth."

    We've already seen many examples of trying to aid foreign countries, and that aid being appropriated by military forces in the country. So, it's often worthless to try to help a country without sending troops to "stabalize" the region and be sure that food, medicine and so forth go where they're intended. Military interventionism is one of the things that the US is always being beat up about -- in other words, we can't win for losing here. If we help, someone hates us. If we don't, someone hates us. Simply put, there is no way to do the right thing by everyone no matter how good our intentions are. Do nothing, we're wrong. Do something, we're wrong.

    2. Afghanistan would be insulted by our weight loss industry.

    There's a number of things about our culture that offend other countries. The idea that not wanting to eat (bulimia, anorexia) is a disease would probably disgust them as well... again, I really think that the WTC attack was as much a religious and cultural issue as it was a protest of any foreign policy -- that's just an excuse. I think that the old-guard in the Taliban and other Islamic terrorist organizations are just itching to try to wipe out cultures that don't agree with them. It's really hard to convince your wife or daughter that she's inferior and shouldn't read, write or be uncovered in public when you have women like Madeline Allbright as Secretary of State for the most powerful country in the world.

    3. Our foreign policies as an excuse to attack us. Changes must be made.

    No doubt, bin Laden has drummed up support by playing up our support for Israel. Again, however, if we weren't involved with Israel but just fail to help Palestine, they'd find fault. We're a target not so much because of our policies, but because we're the biggest guy on the block. If you're top dog, there's always someone who wants to knock you down. That's not to say our foreign policy isn't faulty, but the fact remains that there is no way we'll be able to walk the tightrope well enough to keep from pissing someone off. If we change foreign policy to please people like bin Laden, we'll not only be seen as a "Great Satan" by someone -- we'll also be seen as weak. Also, the things that we're hated for abroad, you can be sure that our every fault is exaggerated in what passes for the Middle Eastern press. Truth in reporting isn't a big concern for people with terrorist ties.

    4. Our actions have claimed more lives than the attack itself.

    Maybe. By whose count? Also, the point wasn't to kill an equal number of people -- we'd have been happy if the Afghanistan government or people would have just turned bin Laden over to us with no bloodshed whatsoever. They refused. Now they're paying the price. Not to sound callous, but it could have been prevented. I, for one, doubt that the present administration is all that anxious to find bin Laden -- they want to drag this out as long as possible to keep attention away from all the nasty things that Bush administration is trying to do. Yes, I'm a cynical bastard, and yes, I think that Bush and his cronies are evil.

    I think the bottom line is this, as a country the people of the US need to pay more attention to what we're doing in (and to) foreign countries. We should not be intimidated into ceasing to try to help other countries, but our "leaders" need to take a longer view of things. We often get fired up about a cause, jump in and then get bored and leave a big-ass mess behind. That's a gross oversimplification, but it pretty much holds true. Our foreign policy changes almost daily, and we're not very good at predicting what the outcome of our actions is going to be down the road. Of course this leads to trouble.

    Just spreading the wealth isn't really possible. Pouring money into another country really doesn't work. Anything more involved is seen as heavy-handed. I wish there was an easy answer for this, but there's not.

    Your first three points have good merit and I agree with them for the most part (there's a lot of agruments either way). However I disagree on the final point. I want you to think about this statement, " we'd have been happy if the Afghanistan government or people would have just turned bin Laden over to us with no bloodshed whatsoever." Why should they have turned over Bin Laden, think about it from their point of view. A massive terrorist attack is committed against the most powerful nation in the worl, a nation that much of your country also despises as the "Great Satan". Now on circumstancial evidence this nation now demands you turn over what is almost a national hero, a terrorist albeit, but a very popular figure. The US had basically convicted Bin Laden within days of the attack (innocent until proven guilty out the window), from the Taliban's point of view regardless of your personal relationship with him or your involvement with the attack you cannot turn over Bin Laden. To do so would not only be an admittal of guilt when you see no evidence but also a huge sign of weakness. The US essentially invaded a country and destroyed a government on a hunch.
    On an interesting note I wonder what would of happened if some of the terrorists involved were found in Canada. You can be sure that the US would want the death penalty and we have a law that does not allow us to hand over a prisoner to a country where they could face the death penalty (maybe we could give him over on a lesser charge like they did on Law and Order:).

    As to the fact of the US's policy of massive interventionism I believe this comes from the first two world wars. I've basically heard it stated that the US was late for the first two world wars so decided to be early for every other one.

    However, a flow of water droplets is major deterrant against both flash-over and heat damage. In the wake of the Piper Alpha disaster (an off-shore oil rig that burned out of control), British Gas did some life-sized experiments with sprinkler and found that starting the sprinkler as early as possible slows down the fire, as well as cooling it (which prevents flash-over).

    Classic sprinklers just dump a lot of water. Modern sprinklers saturate the air with tiny water droplets. The modern ones are very effective.

    In the wake of september eleven, I hope that sprinkler will get the attention it deserves. And that includes trying to figure out how to get enough water from smaller tanks on each floor, rather than from huge tanks with vulnerable pipes.

    Self-preservation?

    Yes, I realize that Afghanistan's national pride would have taken a hit if they had just handed him over -- but a lot of people would still be alive. The Taliban would likely still be in power. The outcome -- a prolonged military attack on Afghanistan -- was a foregone conclusion if they refused.

    I also disagree that this was just "a hunch." For one thing, I believe that the administration still has evidence that they're not sharing with the public. Another is the fact that this isn't the first attack that bin Laden has orchestrated, merely the most successful. It's my understanding that there is very conclusive evidence that he has been responsible for previous terrorist attacks against the US.

    What would have happened if bin Laden was in Canada? That's a good question. Surely, we would have been loathe to attack Canada, and they would be just as unlikely to turn him over knowing that we'd be likely to sentence him to death. (Actually, I'm not sure we would. Killing bin Laden makes him a martyr, particularly if it were a scheduled execution that the entire world could focus on rather than dying anonymously in some cave...) However, we're far more likely to allow Canada to try him in Canada because we know that Canada would actually give bin Laden a fair (fairer, anyway) trial than Afghanistan. (Or the US, for that matter...) Who really believes that the Taliban would have tried bin Laden, or found him guilty if they did? He was there for a reason, because the government and many of the people supported him. They backed the wrong horse.

    Canada isn't really a good example, anyway. Say bin Laden was in a country that we were more neutral with, like the Czech Republic or Kenya. Would we attack them if they refused to hand him over? Would they have handed him over without a fight? That's a good question, I'd say we likely would have, eventually. But more likely, those countries would have handed him over.

    Frankly, if I were the president when something like this happened, we would have been bombing Afghanistan within 48 hours if they refused to hand him over. It was a foregone conclusion anyway, giving them a long time to think it over was a mistake to wait so long as it was.

    As for the policy of interventionism... that's probably part of it. The fear of communism is probably a bigger factor, but we've gotten in the habit and forgotten why we started.

An experiement (and I'm not suggesting you do this) is take two equal piles of trash/wood. Start one with a match, douse the other with kerosene, and light. The second one with the ignited kerosene will have a much more intense and energy producing blaze because the fire was started with a higher heat and over a much larger surface area.

    Fact: The Arab nations have launched several wars of aggression against the state of Israel. These attacks were unprovoked. During the course of these wars, Israeli forces pushed back the Arab forces and took the lands now called Gaza, the Golan Heights, and the West Bank. The Arabs rolled their dice and lost. Now they carp about being "occupied". Perhaps they should've thought about that before they attacked, eh?

    Fact: The Arab press continually spouts vitriolic hate on a daily basis proclaiming attrocities against Muslims by Israelis. The latest farce was the claim that Jews eat a pastry that must be made with the blood of young Muslims. This was stated in the state-run newspaper of Saudi Arabia. Most Arabs believe it, although there is absolutely no proof or evidence behind it. They are just as brainwashed as you are.

    Fact: Young Israeli men and women are not being brought up to strap explosives to themselves, wander into a crowded restaurant, and blow themselves and as many Arabs up as they can. Apart from two incidents where deranged Israeli's shot several Palestinians, there have been no acts of terror against innocent civilians by Israeli's. Today we heard of the fourth day in a row where another young Arab blew himself to Allah while taking out folks eating lunch. Mighty brave of him, preying on people who had no defenses, had done him no wrong. He even killed a few Arabs as well. I wonder how that sits with Allah, eh?

    Fact: When the WTC towers were destroyed, Arabs danced in the streets, yet they continue to depend on the west for investment cash, technology, and popular culture. I don't care if 3000 Muslim's, Christian's, Jew's or whatever were killed, nobody should be dancing in the streets celebrating it. It was a brutal, uncivilized act of a coward, striking out from the shadows because he cannot strike any other way. The perpetrators of 9/11 will get their comeuppance, in this world or the next.

      Three problems. First of all, planes are routinely restored to good-as-new condition as part of regular, government mandated maintenence. As this is less expensive than building a whole new plane, planes really are never "worn out" though you may get models that are out of date and not worth using anymore. These planes will be OLD though, things like 707s.

      Second, have you been to ground zero? The parking meters for a good block or so away from the hole actually have the plastic faces melted off. Though it may look tidy now, I would guess that there was far more collateral damage than would really be permitted in a controlled demolition.
