A tie back is a crucial safety and support system used in construction, particularly during excavation and foundation work. It's like an underground anchor that helps hold back soil and support walls during deep digging projects. Think of it as an invisible support system that prevents walls from collapsing inward when contractors need to dig deep holes for building foundations or underground structures. This method is commonly used in urban construction where space is tight and buildings are close together.
