Precise track surveys with reference and verifications of the gauge and the altimetry were carried out every 30 meters and every 5 meters from the center of the line.

The purpose of the assignment was to measure and verify the alignment, parallelism and altimetric dimensions of the current status of the crane tracks and then returning plano-altimetric data.
