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.

  • β€ŠStacy 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.

Hey chat I found a vegan Sour Cream Flavor powder, anyone ever try anything like that? Vegan dairy alternatives suck donkey ass, at least the ones I've used so far, so if stuff like that works good it'd really expand the range of flavors I can blast these college kids with

That's funny I've been finding vegan dairy alternatives have made great strides in the past five years. Now you can get genuinely good butter made by major companies for the same price as cow butter. Oat Milk is simply superior to cow milk (which is trash). There are good sour creams, cream cheeses and ice creams now. Pea protein has made a big difference.

No good regular cheese AFAIK, all these boutique expensive "cheeses" just don't hit. And I don't really fuck w yogurt but last I checked they weren't right either.

My guess is it's area dependent what people have access to though. I live in a lib city where no restaurant lacks a vegan option and they all have at least three vegetarian entrees

also let me use a second comment to say yeah the pea protein based beef crumble products, I don't remember if they're impossible or beyond beef brand, but they're very beefy. I could 100% make chili that nobody could tell was not full of beef if I didn't tell them what was in it

Idk where the beef flavor even comes from honestly because it's like full of stuff like pomegranate extract lol

I heard the key to the beef flavour is heme
