Demolition is the opposite of construction: the tearing-down of buildings and other structures. It is contrasted with deconstruction, which is the taking down of buildings while carefully preserving valuable elements for re-use.

For most buildings, such as houses, that are only two or three stories high, demolition is a rather simple process: the building is simply pulled down by excavators or bulldozers. Larger buildings need the use of a wrecking ball that is swung into the sides of the buildings. Wrecking balls are especially effective against masonry. This process is quite slow, but it puts the operator of the demolition equipment at a safe distance from any falling debris. In recent years this technique has fallen out of favour because of its slowness.

Building implosion

---

Large buildings, tall chimneys, and increasingly some smaller structures are destroyed by building implosion using explosives. Imploding a building is very fast — the collapse itself only takes seconds — and an expert can ensure that a building falls into its own footprint, so as not to damage neighbouring structures. This is essential as most tall structures are in dense urban areas. Any error can be disastrous, however, and some demolitions have failed, severely damaging neighbouring structures. The greatest danger is from flying debris which, when improperly prepared for, can kill onlookers. Even more dangerous is when a building fails to collapse completely. This often leaves the structure tilting at a dangerous angle and filled with undetonated explosives, making it unsafe for workers to approach.
