Scaffolding makes access to a building’s exterior easier for renovation. Internal staircases and elevators in taller buildings are often built much later than the outer shell. Access is often only possible by using exterior scaffolding which is often built storey-by-storey as building work progresses. It is a fairly straightforward process to dismantle the exterior scaffold once it is surplus to requirement.
External scaffolding should be designed and produced to suit a particular shape and height of the building it will be used on. Modularity is a significant part of scaffold design and scaffolding equipment manufacturers should take this into account when producing standard sizes for their materials.
