Even when everything is carefully planned, choosing the appropriate demolition technique is crucial to prevent shortcomings.
When buildings are no longer needed they are often demolished to make space for new construction. However, collapsing a whole building is not an easy task to do.
How is this task achieved safely and efficiently by construction specialists? There are several methods to do this: experts can either use explosives, a high reach arm, a wrecking ball, or selective demolition techniques.
It seems that construction specialists are spoiled for choice. How do they choose one of these techniques? Or more specifically, how do they choose the right technique?
That all depends on a variety of factors that include but are not limited to the size of the building, its location, the reason for collapsing it, and how the post demolition debris will be handled.
It is crucial that specialists get the right technique in place as sometimes things can go terribly wrong even with the best of planning. One such example is the demolition of a silo in Vordingborg, Denmark in 2018.
The large building fell completely the wrong way much to the surprise of construction specialists. It ended up completely destroying one neighboring building and damaging several others. Find out more about this incident and the many ways there are to collapse a building in our video.
