Every building works needs some kind of scaffolding in order for the builders and other tradesmen to work on parts that can’t be reached from the ground. Scaffolding can be a simple structure for single storey buildings or a highly complex structure for the many high-rise buildings that go up in cities across the world.
One thing is for sure, the building cannot be completed without this structure and if it is not safe nasty accidents will happen. And often, lives can be lost. When the scaffold collapses it is usually because it was not designed or built properly. The fault for this lies directly with the building company who ordered the scaffold. They should know to only use a scaffold company that has a good reputation in the trade for doing excellent work.
