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.

    In canon the original trilogy starfighters are substantially better than prequel trilogy technology but it's largely because the imperial war machine kicked up and prioritized weapon's research and capital class fighter development/production over basically everything else (even lying to and then forcibly working research groups regarsing energy research that was really only meant to ever power the death star). This is the father of Rogue One's protagonist's plight if you'd forgotten. The empire also used tons of slavery and various dealings with regional feudal lords for mass raw resource extraction and the expanding colonization and resource extraction is what was fueling the entire war economy.

    The core imperial worlds (and only really the aristocracy within them) were really the only beneficiaries of technological advances. The further you got from the imperial core the more explicit the relationship became "You and your planet exist to fuel our colonial war machine. Get in line or die."

    In both new and old canon it's explained the Emperor basically backed the wrong camp (Grand Moff Tarkin) who decided having a superweapons and slow, large battleships, the Death Star and Star Destroyers/Super Star Destroyers respectively, were more important than a much, much greater quantity of better equipped and defended fighter group (the tie defender project).

    I apologize to anyone reading this for me knowing it but I'm also glad to answer more questions if anyone is curious.

      oh yea the Tarkin doctrine which was basically mass state terrorism vs thrawn that just wanted a effective colonial administration

        Exactly. I haven't read enough of old Legends content to know about the Chiss Ascendancy in any real level of detail, but my tiny hope for new canon is that it provides more interesting storytelling foundation like Andor (and to a much lesser degree Ahsoka) than the other Disney content.

        The further away they get from Lucas' work the more experimental the writing groups get (Dr. Aphra comics are a good time and The High Republic era has at least been novel albeit I feel it's dipping in quality currently).

        I recognize Star Wars is slop, but I just hope they feel more empowered to try things rather than tell/re-tell "safe" stories.

          I too like the slop and i wish they would take more risks like finally doing post sequel content, but then again mandoverse is the biggest risk they have taken. I wish they did more sith stories that arent about palpatine or vader.

          I think the new canon thrawn book do explain a bit more of the chiss than the old legends ones if you havent read them

            I liked the new Thrawn books a good bit, but I'm at the point now where my curiosity is with the Chiss Ascendancy itself and I want a story about it directly instead of Thrawn's navigation of his relationship to it and pacifying the Empire to its existence.

            Star Wars needs new societies to explore and I think both Mandalore and the Chiss Ascendancy are great places to do that in interesting, novel ways.
