A scaffold provides masons with a safe platform to work on as the building's height rises. Scaffolding is a temporary structure for supporting several platforms that workers can use as required. When walls, columns, or other structural members of a building exceed 1.5 m in height, temporary structures must be built to support a platform when the workmen can sit and continue working. Scaffolding is a temporary structure, usually made of steel or timber, built very close to the surface of a wall. All components of the scaffold should be checked thoroughly before use to ensure safety and integrity.
