Planning The selection of the route
The selection of the construction methods Geotechnical investigation Investigating soil structure, soil strength,
permeability, ground water condition etc. Staking out of the construction (layout) Using coordinate system or reference system
Tools: tape measure, theodolite, electronic distance measurement devices, GPS…
