Excavation carried out for the construction of individual foundations and trenches is typically referred to as "foundation excavation." This process involves removing soil and other materials to create a stable base for building structures, ensuring they can support the loads they will bear. Proper excavation is crucial for preventing future structural issues and involves considerations for depth, width, and soil conditions. It may also include shoring or bracing to prevent collapse of adjacent soil.
