You have seen a stone being demolished using a mere sledgehammer and you think how tough can buildings get. Well, there are different theories of building demolitions and the process applied. However, it must be kept in mind that demolishing a high-rise building is easier than getting rid of a skyscraper that is 20 floors or above. Hence domestic demolition is a much easier option. There are different ways to execute it which are as follows.
One of the common procedures and most suggested ones here would include explosive demolition. Not only is this method suggested but also recommended because it is safe and efficient to do. The structures, especially larger ones, can be easily demolished using this. Usually, the term implode is used here because it causes the collapse of the footprint of the building rather than spreading to outer areas. You may be awed by the blast and the cloud of dust that forms, thinking how quick that was, but in turn, domestic demolitions are a process that requires a lot of planning and thinking.
Guidelines on how to do domestic demolitions:
- Size of the building: The general theory for the demolition of buildings is that the bigger they are, the more difficult the process of implosion is. The simple theory that is put into practice here is to ensure that the support structure of the building is demolished well. So if one was to remove the support structure from a particular point, then the building would only fall below that point making the process less tedious. One complication in this process of domestic demolition is that if upper section is heavier, then it may collide with the lower part, thus leading to damage. Explosives just trigger the collapse of the right parts. And then gravity does its job.
- Multiple points in domestic demolitions: The demolition devices or the blasters are set at different points across the building. The idea of putting the blasters at different points helps in bringing the building down. The total damage here would be caused by a complete and organized collapse if everything goes as per execution. This also means that the rubble which is left behind is only a pile and thus easier to clean.
- Mapping out the domestic demolitions: Blasters ensure that all building demolitions are done as per planning. The maps are then handed over to the staff who in turn plant implosion devices. But planning in itself takes a long time as the architecture type of the building is examined along with checking out how the entire building was put together. Then the blaster crew starts taking notes about the different support structures. Once all of this raw data is put together, a new drawing or blueprint is created for the same. Precedence’s and past experience of similar buildings are then gathered to create a new plan for the demolition process.
Challenges in domestic demolitions
There are many different kinds of challenges that architects and blaster crews face in building demolitions. Some of these are as follows-
- How the building falls is crucial. One wrong blast can make the building fall on the wrong side, leading to damage and even prove fatal. In this reference, open areas around the building are secured for this purpose.
- To topple in one direction is all the more tough as the right planting is necessary.
- In some cases, secure steel cables are required for supporting different columns and these need to be pulled first to ensure that the crumbling process is done right.
With these factors in mind, building demolitions take place to ensure that old buildings, especially worn out ones are brought down and new ones constructed in the place.
