The gradual improvement of modern rail networks and the emergence of high-speed lines requires the most accurate and efficient surveying and monitoring using equipment from Leica Geosystems.

The E18 Bjørvika project, scheduled to be completed in February 2010, will improve the environment of Oslo’s inner city and enhance the area around the new opera near Bjørvika harbour by moving traffic underground – and under water. Part of this ambitious project is a subsea tunnel – the first one ever built in Norway – consisting of six 100 m long elements. The shape of the tunnel is an additional challenge for the engineers: each element is curved, and some of them were built on a flat floor in the dry dock, but will have to fall to the seabed to reach their final destination. A case for Leica Geosystems’ High Definition Surveying™, as told by Frode Edvardsen from contractor Skanska in Norway. more

"The use of innovative 3D laser scanning technology from Leica Geosystems meant that Australian surveying company North Surveys were able to complete the survey of a section of rail network in record time and with an extremely high level of accuracy (Reporter, Issue 49, December 2004)." more

“Without the Cyrax system enabling us to extract data under controlled office conditions we would not have been able to provide results to the timetable required. Also, collecting and labeling data in the field on a discrete point basis is very prone to error and increases time spent in a dangerous environment. Errors in discrete points are difficult to trap and will inevitably mean a revisit to site. With the Cyrax system all data could be fully QA’d by over sampling without time penalties and all processing was done off-site.”
