With a length of 5.34 miles (8.6 km) the Saale-Elster viaduct on the new Leipzig-Erfurt rail link will be the longest railway bridge in Germany. The construction is currently being tested and will be put into service by mid/end 2016.
terra® is monitoring the viaduct's behaviour over a period of 2.5 years using an automated bridge monitoring system.
The measurements will provide construction engineers with valuable data on the interaction between the viaduct structure and the slab track superstructure for this particular project and future projects.
We deliver all services for railway companies from one source. Our services include surveys & monitoring or tracks, catenaries, bridges and railway infrastructure. Railway companies in Switzerland and abroad trust us.
Our 360 degree Panoramic Imaging Service can be easily combined with 3D-laserscanning based mobile mapping. We map streets, railway infrastructure, large objects as well as landscape. Depending on customers requirements we deliver geo-referenced 360 degree panoramic images, single images or videos.
Based on our mobile mapping solution we have scaned the network of contact line for the local transporation company in Geneva. The data acquisition has been performed within a few hours. Following our customers request we have transferred the positioning data of the contact lines in georeferenced 3D-models. Watch the video now.
When building plans are missing or outdated, laser scanning provides a perfect solution for fast, detailed and accurate building inventory surveys.
Reliable building surveys play a vital role in the planning of any reconstruction or renovation project.
Often, plans for historic or landmarked buildings are not available. If plans or drawings are available they often no longer reflect the actual conditions and new building surveys may be required.
The article "Neue Dimensionen beim Monitoring" in the recent issue of Sicherheitsforum describes the most important aspects regarding our monitoring solution swissMon for the project Durchmesserlinie in Zurich, Switzerland.
