How much can a shoring box be undercut (maximum)?

The maximum amount a shoring box can be undercut is 2 feet. This specification is crucial to ensure safety and structural stability during excavation activities. When a shoring box is used, it provides support to the walls of an excavation site, preventing collapses and protecting workers who might be working in or around the excavation. Undercutting beyond 2 feet increases the risk of destabilizing both the shoring box and the surrounding soil. Adhering to this limit helps to mitigate the risk of failures and ensures that operations can be carried out safely. Understanding such limits is essential for maintaining compliance with safety standards and regulations within the construction and excavation industries.
