Foundation outline | Marking for Footing excavation | Site engineer | Structural

Excavation Procedure :-

1. Mark the baseline on the ground from the centerline of the road, or a permanent building nearby. This line helps to mark out the front of a building.

2. Use a side structure, road, first baseline, or plot boundary to mark side baselines of the building.

3. Fix temporary pegs at the centerline of walls/columns on both sides of walls and columns in front and backside.

4. Fix peg at the centerline of walls/columns on both sides of the walls and columns on the left and right side of the building front.

5. Check diagonals of the square or rectangle formed after fixing pegs.

6. Construct marking pillars with pegs at a distance of 1.5 meters to 2 meters, and plaster their top surface.

7. Mark center line on the top of marking pillars with the help of thread (Soot) or with the Theodolite in big projects and the diagonal, and check other dimensions.

8. Level marked pillars on all corners of the building.

9. Mark the foundation of walls/columns according to drawing on the ground with the help of centerline marked on the marking pillars.

10. Use chalk powder to mark the foundation trench on the ground.

11. Excavate the foundation of the walls /columns up to the required level, and check the excavation with the help of centerline and level marked pillars to avoid any complication later on.
