Scaffolding, or staging, is a temporary structure used to support a work crew and materials to aid in the construction, maintenance, and repair of buildings, bridges, and all other man-made structures. Scaffolding is also used in adapted forms for formwork and shoring, grandstand seating, concert stages, access/viewing towers, exhibition stands, ski ramps, half pipes, and art projects.
Depending on their use, scaffolds may be categorized as access scaffolds or support scaffolds. Access scaffolds are used to support light to moderate loads from laborers, small construction material, and equipment for safe working space. They are usually attached to buildings with ties and are only one bay wide. Support scaffolds, also sometimes called falsework, are subjected to heavy loads, for example, concrete weight in the formwork.
