What is setting out in engineering surveying?
The method of setting out is the reverse of surveying process. The process involves the positions and levels of building lines and road alignments shown on the construction plans to be established on the ground by various techniques and instruments.
What does a surveyor use to measure?
Surveyors determine the position of objects by measuring angles and distances. The factors that can affect the accuracy of their observations are also measured. They then use this data to create vectors, bearings, coordinates, elevations, areas, volumes, plans and maps.

How do you get accurate measurements out of a building?
SETTING OUT OF BUILDING The tops of the pegs must be level for accurate measurements to be obtained. This is achieved by making the first peg (usually on the front line of the building) a datum peg. It is from this peg that all the other pegs are levelled.
