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.

    Sounds dope but it's impossible to make a non vegan college kid eat anything at all that doesn't countsin meat. Even toast

      They eat some things. Like my butternut squash chili fucked them up one night. I think the most successful though are just like rice dishes. "Beyond" ground "meat" seasoned with thai chili put on rice? They ate it like a regular side/ entree even

      There's very much a component of judging how it looks as well as hearing that it's vegan and going ehhh

        That all sounds awesome.

        The most popular college food is always basically fast food dishes popular with kids. Burgers, sub sandwiches, pizza, Americanized Chinese food, that kind of thing. Vegan pizza is usually very different from non-vegan so that is a risky one. But for the others I would wonder if they would be popular if they were jazzed-up with a crowd pleaser.

        • The Burger has an onion ring in it.

        • It's a nice Italian sub, I.e. the most popular kind, and there is no non-vegan option.

        • The deep-fried chicken option is vegan and comes with a boatload of crispy garlic and onions.

        • The egg fried rice uses black salted tofu instead of egg and comes with some egg rolls (college kids lose their shit over egg rolls).

        Two more ideas.

        You could make some dishes that are "accidentally" vegan. Then you don't have to put vegan in the name itself at any point. It's a pomodoro pasta. It's dal makhani. It's a nice falafel plate. It's kimbap. It's a Thai curry whose protein just happens to be fried tofu.

        Finally you could strategically deploy the "plant-based" label because it is less scary to food cowards.
