Excavation depth

The excavation depth is the difference in height between the height of the original earth's surface and the floor of an excavation pit .

In simplified terms, a greater excavation depth also entails higher costs, since the relevant soil (the excavation ) must be moved and possibly also removed from the construction site and deposited. From a certain excavation depth onwards, the lateral soil must be sloped or supported for safety reasons . This support is referred to as (construction pit) shoring . The type of shoring that must be selected is specified in standards and depends - in addition to other factors such as the soil class - primarily on the excavation depth.

The greater the excavation depth, the greater the need for dewatering , which can also result in considerable costs.
