Scaffolding, shoring, and underpinning are all used in building construction to support and strengthen the structure: Scaffolding: A temporary structure used to support construction workers, materials, and inspectors who need to work at height. Scaffolding is typically made from metal poles and wood planks. There are many types of scaffolding, including single, double, suspended, steel, trestle, and patented. Shoring: The process of temporarily supporting a building, structure, or trench with shores (props). Shoring can be vertical, angled, or horizontal.  Professionals use shoring... Show more
