To "demolish" means to completely tear down or destroy a building or structure. This process often involves heavy machinery, such as excavators and wrecking balls, to safely dismantle the materials. Demolition is typically carried out for various reasons, including making way for new construction or removing unsafe structures. Demolition can be categorized into two main types: controlled demolition and deconstruction. Controlled demolition uses explosives to bring down a structure in a precise manner, while deconstruction focuses on carefully taking apart a building to salvage materials for reuse. Both methods require planning and safety measures to protect workers and the surrounding area.
