In the context of excavation, a 'bench' refers to a relatively level step that is created in the side of an excavation. This step is important as it helps to reduce the risk of soil collapse, providing stability and safety when working in deeper excavations. By creating benches at levels, workers can access different depths of the excavation more easily and safely.

A bench also serves to control the depth of cuts made during excavation, which is particularly crucial in maintaining the integrity of the surrounding soil. The use of benches can facilitate drainage and enhance visibility within the excavation site, making it easier for workers to handle the materials being excavated. This construction practice is common in various types of excavation projects, ensuring that the site is safely managed while achieving the desired topography.

Understanding the concept of a bench is essential for contractors and workers in the excavation field, as it directly impacts safety protocols and effective construction methods.
