However they are captured,
precise rail as-built surveys
are the key.
Having the initial as-built information of the track, including
coordinates of the rails, cant, gauge and station information,

In 2023, Swiss surveying firm GEOGRID AG was asked by
a customer to support a rush project. The contractor was
building a retaining wall between the river and the railroad.
"We got a call on a Wednesday afternoon and needed to install

of rail. That monitoring solution needed to operate 24 hours
a day throughout construction, about six months," said Moris
Berchtold, GEOGRID AG project manager of engineering and
surveying and head of the department of monitoring.
