The idea behind demolishing a building is this: removing the support structure of the building will make all of what is above it come crashing down. The upper part of the building above the structure that is first demolished will subsequently fall on the lower part if it’s heavy enough. This will lead to a cycle of the upper sections falling over the lower ones one by one until the ground is reached. To do this, demolition companies make use of explosives and blasting. It may be hard to believe but explosive demolition is actually the safe way to reduce a building to rubble especially when we’re dealing with a giant skyscraper. But the explosions just help to trigger or initiate the demolition process; it’s actually gravity that does the rest of the job.

Demolition companies will plant detonators and explosives in different sections of the building so that the building collapses entirely with gravity into a pile of rubble. This also makes the cleaning part sufficiently easier for the cleaning crews.
