Permission to build on their hands, so you can get to work.
Why counting begins
The first step is to mark the future walls of the house on the site, I removed all foreign objects and debris. Removed weeds and other plants that were within the structure of the future.
Having the permission to build up to the minimum margins from the border area and on neighboring buildings, the place I chose the property line - from which has made the first measurement. In my case, it was necessary to enter the structure with dimensions of 8 m. X 10 m. In area portion with a size of 13. Meters x 37 meters, considering the fire offsets from neighboring buildings -. At least 6 m, and the offsets from the boundaries 1. meter.
Previously, the program for the modeling of objects, I made a plan of his own and neighboring areas strictly observing all sizes (for Surveying), as well as the future home of contour (highlighted in red). Within 5-10 minutes, I entered the house to the site, taking into account all the constraints of the local architecture.
Once exact values of the indentation area boundaries are already known (in my case, the boundaries of the left -. 1.1 m, from landmark Right - 1.85 m, and from my site facade -.. 22.1 m), I measured out the tape measure the required dimensions and scored the first peg.
Required materials and tools for layout:
- wooden pegs;
- board (for the construction of the frame);
- monofilament yarn or monofilament construction;
- roulette;
- ax;
- hammer.
Next, using a tape measure and measuring out length house walls and scored at each corner one peg.
geometry Analysis
All the walls of my house should be equal to 90 °, the why the Pythagorean theorem (the sum of the squares of two of the legs must be equal to the square of the hypotenuse), I calculated the size of the diagonal, which amounted to 12.8 m.
So I got the desired right angle between the two sides of the house. Similarly, check and correct the lengths of the other sides, after which control measurement made mandatory two diagonals, which agreed with an error of 0.7 cm. (Allowable error: 1-2 cm.).
castoffs
Rags - a temporary structure, usually wooden structures created to secure the stakeout axes. It serves for the removal of a cord anchorage (fishing line, thread) outside the place of construction work.
With a perimeter of the future structure, performed castoffs.
Alignment on the plane
Once the perimeter of the building transferred to the cast-offs required to place all of the cords in the same plane. In the future, this plane will be denoted the zero point construction of the foundation. Which I did.
Plane exposed with a laser level and the water level (water level) by leveling boards along the horizontal scored stakes. In my case, the board segment was fixed with screws on wood, so it was easy to move the rail vertically.
All work on measurements, including verification of geometry and alignment of the plane should be carried out very carefully, because of the right of laying the foundation depends on the design of all future structures.
The main thing - to measure seven times and once to dig up !!!
