First remove the topsoil and level the soil area. Then, in accordance with the draft bath, apply a contour of the foundation. The width of the base is calculated based on the construction of walls, but not less than the width of the wall with the addition of Prepare a 10 cm length 50 cm pegs, cord, tape measure, level and right-angled triangle, made of thin slats, and legs having a length of 30 and 60, see Schedule a corner bath and drive a stake into the ground. Then put it triangle and one outside, measure its size, equal to the length of the longitudinal walls of baths, but on the other – the amount equal to the length of the transverse wall in the axial lines. At the ends of the size of the wall (at the intersection of axes) to the points obtained drive in the second and third pegs. After this, move the triangle to the opposite corner bath. Determine the axis and drive in the fourth peg.
To believe is correct driving pegs, compare the resulting diagonal rectangle. With the right by the diagonal will be equal to the difference or have less than 20 mm. Then place the old clothes at a distance of 1-2 meters from the pegs. It is made of columns with nailed planks to them. Nail boards to a height of 1-1.5 m from the ground or at the level (elevation) of the floor bath on the project. Make sure that the direction boards castoffs were strictly parallel to the walls of the bath.
Before attaching the boards castoffs to the post, please check the entire structure with level and reiki. Then proceed to spray the foundation plan axial dimensions at the upper edge of castoffs. To do this, type in the nails into the notches between them and pull the rope so he came over strongly driven into the corners of the house with pegs. Tighten all the axes and check them out. Then transfer the axial lines of the pitch with a plumb and put them in hand the required size. Draw a line on them, defining the contours of the inner and outer sides of the foundations. Further you can begin to prepare trenches or pits for the foundation. Erect foundation immediately after excavation. It is desirable to complete the construction of baths in a single season. using the reference to the original material is required
