Building implosion

In the controlled demolition industry, building implosion is the strategic placing of explosive material and timing of its detonation so that a structure collapses on itself in a matter of seconds, minimizing the physical damage to its immediate surroundings. Despite its terminology, building implosion also includes the controlled demolition of other structures, like bridges, smokestacks, towers, and tunnels. This is typically done to save time and money of what would otherwise be an extensive demolition process with construction equipment, as well as to reduce construction workers exposure to infrastructure that is in severe disrepair.

Building implosion, which reduces to seconds a process which could take months or years to achieve by other methods, typically occurs in urban areas[citation needed] and often involves large landmark structures.

The actual use of the term “implosion” to refer to the destruction of a building is a misnomer. This had been stated of the destruction of 1515 Tower in West Palm Beach, Florida. "What happens is, you use explosive materials in critical structural connections to allow gravity to bring it down.

The term “implosion” was coined by my grandmother back in, I guess, the '60s. It’s a more descriptive way to explain what we do than “explosion”. There are a series of small explosions, but the building itself isn’t erupting outward. It’s actually being pulled in on top of itself. What we’re really doing is removing specific support columns within the structure and then cajoling the building in one direction or another, or straight down.

  • Stacy Loizeaux, NOVA, December 1996

Building implosion techniques do not rely on the difference between internal and external pressure to collapse a structure. Instead, the goal is to induce a progressive collapse by weakening or removing critical supports; therefore, the building can no longer withstand gravity loads and will fail under its own weight

Numerous small explosives, strategically placed within the structure, are used to catalyze the collapse. Nitroglycerin, dynamite, or other explosives are used to shatter reinforced concrete supports. Linear shaped charges are used to sever steel supports. These explosives are progressively detonated on supports throughout the structure. Then, explosives on the lower floors initiate the controlled collapse.

A simple structure like a chimney can be prepared for demolition in less than a day. Larger or more complex structures can take up to six months of preparation to remove internal walls and wrap columns with fabric and fencing before firing the explosives.

    I’m already so tired of hearing about this fascist fuck. There are much more important things going on than that dead motherfucker. I might have to take a break from the internet, because this shit is making me go insane.

    Yesterday started off like any other wake up, drag myself through work, come home, and settle into the usual routine. I threw some laundry in, grabbed a quick dinner, and was half watching TV while checking scores on jackpot city. Totally normal, totally uneventful. Then out of nowhere, the power flickered and everything went dark for a good minute. When the lights came back on, my TV had switched to some random local channel I didn’t even know I had, showing a late night call in show with one of the weirdest hosts I’ve ever seen. He was ranting about traffic cones. I sat there for way too long, just watching this guy passionately argue that traffic cones are the most underappreciated part of city planning. No graphics, no callers, just him and a table covered in cones. By the time I realized how much time had passed, my laundry was wrinkled, my food was cold, and I’d just spent an hour listening to cone propaganda. Ordinary day derailed, and I still don’t really know what I watched.

    kinda weird that im more willing to say my opinions to my coworkers than type them online, basically the exact opposite of how the internet used to function

    It’s cool and good that we are not the bad people.

    I feel very fortunate in this time to share a space with folks whom have so many positive qualities. Every time I scroll our site I see insightful, intelligent, and compassionate words and it brings me great joy. Also, many good jokes and content.

    Fuck all those rightwing losers; their continued adventurism should bring them all shame if they had any introspection. It’s too bad their favorite bigot died, sucks to suck I guess.

    I wonder what research has been done on the grammar of memes. Because as much as subcultures or younger generations insist their memes are illegible to outsiders usually the intent is very clear. You can take a guess at like the etymology too.

    spoilers for Weapons (2025)

    I saw your take on the movie now that I saw it. I feel like the gun violence commentary didn’t land for me, it seemed to get lost after the second act. Sure, the parents were absent, the kid was getting bullied, and there was the very obvious bit with the rifle in the dream sequence. It even counted up 217 which I assume is a reference to some statistic about victims of shootings. But what was going on in the entire 2nd and 3rd act that illuminates any kind of commentary on gun violence, or anything at all?

    I could kinda see one way the movie is using this Crash (2004) style convergent narrative to portray the aftermath of a close-knit community struck by a tragedy like a mass shooting. But the fact that the kids come back at the end seems to go against that formula, unless it’s also prescribing something. If Crash was a movie about how we beat racism, this seems like a movie about how school shootings or some other atrocity can be solved. But what’s Gladys? Some kind of brainworm infecting the children? Online extremism? Wokeness? It seems like, unironically, wokeness might be the best reading for what Gladys could represent if she’s a straightforward symbol, but Zach Cregger obviously isn’t trying to say that, and it would be pretty bizarre for wokeness to make a dude kill his husband. But she’s too normie-coded to represent extremism, which is the more obvious liberal narrative about what could cause mass shootings. And I don’t think she represents alienation which, if I’m simplifying, would be the materialist answer to the question. So I’m just kinda stumped, wtf was the point of that character? Old women’s bodies are scary, boo!

    In the bits of the movie where it strayed a bit from the usual horror movie formula, i.e. the bits where it’s actually saying something, I was letting my mind go wild about what it was about if not school shootings. I was jumping at shadows, like when Archer goes and asks the other family to see the footage of their kid running away and the number of the house was 1948 I started thinking that it could be about the Nakba! Which, in some ways, works a bit better than the school shooting allegory. Gladys settles in Alex’s home, threatens and extorts him, ramps up violence against the whole neighborhood, and apparently wants to live forever. But that’s a huge reach, and there’s little evidence in the actual structure of the movie that supports that interpretation, although the image of the kids being kidnapped in the basement was evocative of a concentration camp where generations of displaced refugees would stay.

    I guess I’m frustrated that I can’t fit the movie in any sort of box because Barbarian was a much more straightforward “men in patriarchal societies be out there doing some really bad stuff” theme, while this one is throwing me for a loop.

    I got this “v is for vegetables” book basically for free and the quality in it varies so wildly, like it’s A-Z visual encyclopedia of vegetables and associated recipes and like some of this shit sounds great, like this beet tartare (rough chopped roasted beets with garlic, onion, and toasted nuts, with chives and a bit of lemon) sounds great

    then you get to Y and it’s like a paragraph about how yams and sweet potatoes got confused, a straight up “i’mma be real, we needed a Y word” and then the world’s most basic baked sweet potato recipe (did you know you toss them in oil, salt, pepper, and bake them??? wow)
