When carrying out all kinds of earthworks, e.g.. excavations for foundations, making embankments and slopes, you will need a height point, the so-called. spotted, which should be appointed by the surveyor. It should be permanently applied to the nearest permanent element, e.g.. pole, building wall etc.. According to its location, we will measure other heights, e.g.. trench depth or strip height, level the terrain or make a slope of a certain height. This benchmark should be permanently protected against damage.
