How will you mark a site for setting out a foundation?
Procedure for Setting Out Building Foundation The initial step is to mark the corners of the building. After which, the lengths of the sides are checked by diagonal measurements. The axial lines (center lines) of the trenches are marked with the help of profiles, sighting rails, strings, and pegs.
What are the three methods of setting out a building?
Methods of Setting Out Survey
- Setting out buildings by coordinates.
- Setting out with theodolite and level.
- Checking verticality.
- Setting out and alignment in steel framed buildings.
- Alignment and verticality in form work.
- Control and calculation for route surveying.
What are profiles used for when setting out foundations?
Outline profile boards are often used to control trench positioning, width and depth. In order that they do not obstruct the excavation work, profile boards should be set up at least 2m clear of the trench positions.
What are the aim of setting out?
The main reason for setting out (other than to guide the workers as they begin construction) is to ensure the construction remains within the legal boundary. This means there will be no legal disputes later on, such as those regarding property boundaries and rights of access.
Which program is used for setting out points?
Setting-Out Points Using the Total Station Interface in As-Built for AutoCAD.
What is 3 4 5 method in setting out a building?
Using the 3-4-5 Rule. Understand the 3-4-5 method. If a triangle has sides measuring 3, 4, and 5 feet (or any other unit), it must be a right triangle with a 90ยบ angle between the short sides. If you can “find” this triangle in your corner, you know the corner is square.

How do you set out a building plan?
The plan is fully dimensioned at all breaks and openings. One of the methods of setting out of foundations is to first mark the centre line of the longest outer wall of building by stretching a string between wooden pegs driven at its ends. This serves as the reference line for marking the centre line of all the walls of the building.
How are the profiles set for a foundation?
Profiles are set 2m away from the outline so that they do not interrupt the excavation process. The offsets are measured from axial lines and the frontage lines are placed in their correct position relative to local requirements. The cross walls positioning is performed by measuring along the main walls and squared from these walls as required.
