Building implosion

Explosives demolition, also referred to as implosion, is a demolition method that involves the strategic placing of explosives and timing of its detonation so that a structure collapses on itself in a matter of seconds. It is used to safely destroy tall buildings, bridges, smokestacks, towers and tunnels. This is typically done to save time and money of what would otherwise be an extensive demolition process with conventional construction equipment, as well as to protect construction workers from infrastructure that is in severe disrepair.

The actual use of the term "implosion" to refer to the destruction of a building is a misnomer, as an actual implosion involves a structure being subjected to extreme external pressure, pushing it inwards in itself.
