This is not the first choice when demolishing buildings that contain asbestos. Unfortunately, wrecking balls cause a lot of dust. The building is crushed under the ball’s heavy weight. The operator either drops the ball on top of the structure or takes a swing at it. The ball – which can weigh upwards of nearly seven tons – is typically suspended from a crane by a cable. It was very popular through the 1930s to 1960s. The term “wrecking ball” – as in such-and-such building escaped the wrecking ball – is used more than the actual wrecking ball method of demolition. Finally, the crew sorts through the debris for disposal. The demolition ground crew then breaks them up further. The machine is used to remove the largest pieces of the building. The building is broken up from the top down. This could be a hammer, shears, or a crusher. Various attachments may be used to break up the building. This type of demolition requires a machine, such as an excavator, with an attached demolition arm or telescopic boom that is long enough to reach the top of taller structures. Detailed structural blueprints are used to help the blaster crew identify where the main components of the structure are located. This type of demolition is typically done in densely populated urban areas. With implosion demolition, explosives are used to force the building to collapse down on itself from the inside out. There are several ways to bring down a structure including implosion, high reach arm, wrecking ball, and selective demolition. Owners of very old buildings may determine that it’s cheaper to knock it down than repair it. Or a new structure is more useful to the surrounding community. Sometimes the land is more valuable than the structure. Structures may be dismantled because they have weak foundations, or they were constructed with hazardous materials. There are several reasons why a building is demolished. In our Complete Guide to Demolition we explain the different ways to knock down a structure. But few know how it’s actually accomplished – other than the fact that explosives are involved in some way. Many people enjoy watching all that concrete and steel tumble to the ground. Watching a multi-story building in the middle of a city get demolished is quite dramatic.
