Demolitions are the quickest way to bring down a building or any structure for several reasons, either because it is old and abandoned and its structural recovery and safety setting would be a very complex process compared with the construction of a new building, or for other valid reasons.

Demolition can be performed in several ways, depending on various factors. In case of small buildings, this procedure is faster, because available machines such as cranes, bulldozers, scrapers, pneumatic drills etc. are used. In more complex cases, such as those of large buildings and skyscrapers, the implosion method with controlled explosive charges is utilized.

Controlled demolition may also be performed on reinforced concrete buildings, for which innovative techniques that do not cause further damage through vibration are required. In fact, if structural walls are to be torn down and the parts not affected by the work are to be left intact, probing or cutting procedures through cutting wires or diamond-cut discs are carried out.
