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, such as bridges, smokestacks, towers, and tunnels.
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.
