To use a theodolite to set out a building, follow these steps:
1. Establish the position of the building using a surveyor’s diagram or a previously established permanent benchmark.
2. Mount the theodolite onto its tripod stand and level it with the aid of the built-in bubble levels.
3. Sight the location of the building using the theodolite.
4. Measure the angles between the building location and the point of origin, called back-sighting, and then the angles between the building location and other reference points, called fore-sighing.
5. Use the angle measurements and the distance from the point of origin to calculate the coordinates of each corner of the building’s perimeter.
6. Calculate the lengths of all sides of the building based on the coordinates of the corners and set out the appropriate layout on the ground, typically using rope and pegs.
