How to square foundation laying lines?

1. How to square the foundation line:

1. Before building a house, we first need to determine a baseline, which is the location line of the house. When building a house, it must be built around this location line.

2. Next, wooden stakes must be ordered according to each endpoint of the position line. Generally speaking, the wooden stakes and the position line must coincide.

3. Then we need to draw another vertical line at this position, draw the relevant marks, take this as the center line, and draw a vertical bisector.

4. After you have the vertical bisector, you can use a ruler to draw several vertical lines. You also need to sprinkle white ash on the ground based on these lines to determine the foundation. In this way, the ground baseline will be more square and error-free. The range will be smaller.
