How to start marking for foundation
In the video, the plan of building is given for living room and kitchen room. The center line marking is also provided with 6 numbers of columns. Initially, you have to set the base point as it is very crucial for marking. After that, a base line is arranged from that base point with a thread for fixing the second point.
The centre line of the wall perpendicular to the long wall, is marked by making a proper angle. Right angle is arranged by creating triangles with sides 3,4 and 5 units long. If we set the two sides of the right angles triangle to be 3 m, and 4 m, then the third side i.e. the hypotenuse is assumed at 5 m. A steel tape should be used to fix all the dimensions.

The formula is used here as √(L2+B2)
The right angle can be fixed by applying a theodolite. This instrument is very useful in fixing acute or obtuse angles. Small right-angled Projections are generally laid out with mason’s square.To get the complete instructions, watch the following video.
