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 dont know anymore with this. My ex called me while she was at work, and honestly, aside from checking in, i dont really feel like talking to her right now.

    Despite thinking we’ve worked some new equilibrium, I still have my own emotions to parse through with every thing, and she still wants to be friends. I do too. She’s still friends with a lot of the people in her past, but she framed it like “a lot of people in the past who hurt me”. You hurt ME though, i was always open to work something out. It’s making me so angry like she just wanted out of having to love me instead of helping me get what i was doing wrong. As of right now I’m deciding i cant be in her life if she doesnt love me. I didn’t break things off, i’m not the one running, I’m hurt over what? I can get she doesn’t want to feel the ache that’s come with being with me, but I was still in the love that would move mountains. I’m on my journey already, but what are you getting from checking in with me? I was at a state where I could focus on myself, and now it’s like you cant let me go. I’m not even sharing my broken heart over shared social media, i’m doing it here where you’ll never have to see me cry, it’s all making me feel like i have to push it all onto my shoulders alone more and more and all you could say was that everyone only sees the bad. I never talked about the bad with any of the people I had a chance to talk about this with. Here I am stupid here ready to take you back if you changed your mind knowing I’ll never put you through something like this, because I know how you are with your emotions and maybe when you work through everything you’ll see you made a mistake, but i can’t decide if it’s best for me to wait or not anymore.

    Now it all hinges on the next time we actually see each other face-to-face, and whether you’re grown enough to hold yourself together now that the distance isn’t there to shield your emotions, meanwhile i know how hard it will be to see your face again no matter what happens by the end of the day.

    fuck i dont know what to do.

      You might be one of the people that would benefit from no contact for like at least 6 months. Or better a year or two. Especially with how youre feeling otherwise in your post. Strict no contact, once you’ve finished the stuff exchange/returning of whatever.

        the idea hurts especially. i dont want that, but that’s because i dont want the relationship to be over, but I also cant really figure out what she really wants with all this. We were very close, I helped her leave an abuse friendship she had with someone. I loved her with all my heart because i saw her as someone who deserved to have someone love her with all their heart, and i wasnt afraid to do it. I think back to when i realized we had something, jokingly telling her that “she had something she wanted to tell me” because I knew it, and i felt the same way. She has trouble facing her emotions but is really easy to read. I loved that about her. But i cant give her the opportunities anymore to hide themselves behind digital phone screen and physical distance. I think I am actually owed that much to finish the break cleanly or we repair what’s happened.

        If she’s scared she wont see me again, she should examine why, because I agree with you.
