[0002] A building foundation pit is a trench excavated during the construction process. The size of the foundation pit varies depending on the size of the building. For foundation pits that are generally small in area and shallow in depth, the depth can be measured by two operators standing at the bottom and mouth of the pit and pulling out a measuring ruler or tape measure.
