Inclined scaffolds are found in most renovation projects. This is an additional protective layer built on top of a vertical scaffold, to prevent small things from the above hitting the passers-by. This inclined scaffold at the middle of the high-rise structure was called inclined shelter or safety scaffold. According to the law, for every 18 metres in height, an inclined scaffold has to be built, which should be 2 to 2.5 metres away from the building’s exterior wall. One scaffold was built at Ebenezer School & Home for the visually impaired and another one at Mongkok Police Station.
