A SCAFFOLD is a temporary structure that is built around a building to provide support and access for workers during construction or maintenance. It is usually made of metal, wood, or other materials and is often used in the construction of tall buildings. Scaffolding is also used to provide access to areas that are difficult to reach, such as the roof of a building. Scaffolding is an important part of the construction process, as it provides a safe working environment for workers and helps ensure the quality of the finished product.
