Before the production of earthwork on a well -cleared area selected for the construction of the building, the upper layer of the soil should be removed and the surface should be leveled. Then marking is carried out. At a distance of 1 mot of the boundaries of the cleared area, pegs are driven in the corners of the perimeter, three pegs per corner for each corner. They are nailed horizontally to them and, using a stretched wire or cord, indicate the boundaries of the future building. After which they begin to dig a pit.
