Then located our building exact layout and cross checked the measurement two times.

Then based on the approved drawing, we provided 5feet on each side of the building for open space as per the authorities.

Constructed temporary brick masonry on each outside corner of the layout and marked the centre line of the building. This is the final marking and all the measurement is taken from this final mark.

Before marking firstly we need to check the layout is inclined, square or rectangular. Even if it’s inclined, the building wall should make straight and right angle only. But the compound wall can inclined any direction.

After the base mark on each side of the layout we need to do line marking by room measurement with thread. After that we can do the excavation.
