Excavation work is a common activity in construction projects and involves the removal of soil or rock to create foundations, trenches, tunnels, or other underground structures. However, excavation operations present several hazards that can lead to serious injuries, fatalities, project delays, and property damage if not properly controlled. Understanding these hazards and implementing suitable mitigation measures are essential for ensuring safety in the construction industry. One of the most significant hazards associated with excavation is cave-in or collapse of trench walls.
