Rail Infrastructure

Safety first
Working on rail infrastructure means paying extra attention to safety. Surveyors need to have extensive expertise, a talent for improvisation, stress-resistance and flexibility in order to properly respond to the hectic situations that often arise during surveying activities along the tracks. Jobs often have to be finished in very brief downtime windows. Surveyors must be familiar with the documents they need to have to be allowed to do the work, as well as with the applicable rules. Surveyors who work in rail infrastructure take a Safety Along the Tracks course first. Additionally, our firm is both VCA* and BTR-certified.

Rail infrastructure
The activities vary from measuring the existing rail geometry, deformation measurements of and around the tracks and measurements during new construction of tracks to taking all measurements needed in building a new station.

3D laser scans in rail infrastructure
In addition to the traditional surveying techniques, one excellent instrument to use in this field in view of safety along the tracks is the 3D laser scanner. Scanning is an easy way of accumulating data without the surveyor having to physically walk around the railway tracks. It eliminates the need for downtime, as the working zone falls outside of the clearance profile (2.25 metres from the middle of the tracks). If the working area involves heightened risk, a safety coordinator will be involved.
 
When to choose 3D laser scans
- accurate measurements of existing situations;
- measuring rail geometry and defining clearance space;
- conducting measurements for designing engineering works.
