Chemin de la Scierie 20, 2013 Colomier, Switzerland
In the area of Neuenburg the national road N5 was to be upgraded. As basis for the planning guide assesment plans of the road were necessary. To interfere traffic as little as possible a laser scanner system for the in-situ assessment of the road was chosen.
The distance of approximately 2000 m were recorded within 8 hours. The point grid was approximately 50 x 50 cm, from the point cloud an AutoCAD plan was also generated, where the significant components (crash barrierers, roadsides, manhole covers, etc.) of the road were depicted. An accuracy of approx. +/- 1 cm standard deviation was reached with the applied measuring system.

As part of the general refurbisment of the Inn power plant Töging from June to October 2003 the power plant owner E.ON decided to also renovate the 20 km long power plant canal. This concreted trapez-shaped conduit was built between 1919 and 1924 and was partly renovated last in 1986. The refurbisment related primarily to the concrete surfaces which showed age-related defects.
The surfaces were newly concreted by means of a concrete finisher with the desired layer thickness of 15 cm. The monitoring of the new concrete thickness ensued through a comprehensive recording of the subsurface (actual concrete layer) and the new concrete surface by means of an adapted laser scanner which was mounted on an all-terrain vehicle. A survey point grid of 5 x 5cm was measured with an accuracy of +/-1cm.
The data was processed by dibit software and as a result the client received comprehensive evaluations of the layer thickness (surface plot). With this data the required concrete volume was determined. During the concreting phases the installation quality was checked by concurrent monitoring scans.
