Monitoring and upgrading solutions addressed to bridges and tunnels
Keeping tunnels open during inspection and minimizing tunnel closures and train delays must be carefully balanced with the need to conduct detailed inspections to ensure the safety of rail traffic. It is difficult to analyse the condition of tunnel walls only with visual inspection or point-like sampling drillings, as it is currently usually done, leading to partially subjective inspections. Also, accurate monitoring of the development of the defects and early phase intervention to problems is very difficult without intense digital comparison data.
The ambition of Assets4Rail consists of finding the most suitable method(s) to inspect tunnel wall condition and develop best practice guidelines in order to interpret and analyse measured data for tunnel wall monitoring. The integration of sensor data in a BIM system will help to foster the inspection qualities.
