What is the safe height for Excavation support?

The safe height for excavation support typically depends on various factors, including soil type, excavation depth, and environmental conditions. Generally, excavations deeper than 5 feet (1.5 meters) require some form of support, such as shoring or trench boxes, to prevent collapses. The Occupational Safety and Health Administration (OSHA) recommends specific guidelines based on the depth and type of soil, emphasizing that no excavation should be left unsupported beyond these safety standards. Always consult local regulations and engineering guidelines for specific requirements.
