Sand From where the excavation begins, from where the measurement is done is NGL (natural ground level). In the previous video, we saw that the height of excavation was 2m. We got this height from the cross sectional view of excavation pit / trench. If we go the same cross sectional view, we will see a layer of sand at the bottom, sand is always spread at the bottom of the pit and this is called sand fill.
