In the routine construction work, sometimes it is necessary to have some temporary structure or support to continue the work. When the height of construction exceeds about 1.5 m, temporary structures are needed. Temporary structure is erected close to the work so as to provide a safe working platform for the workers and to provide adequate space to keep the working materials. This temporary structure is known as scaffolding or simply a scaffold. Such temporary structures are used in construction, demolition, maintenance or repair work of buildings.
