3D Laser scanning is a survey method which is quick and safe.The survey of infrastructural objects (e.g. highways) is a dangerous and time-consuming process. The closure of a highway will result in traffic disorder and as a result significant extra costs.

To reduce these costs, 3D Laser scanning is a secure solution which offers more than just a single point survey. Because of the great amount of data gained, more analyses are possible (for example, the possible skew, the possible slanting, etc).

Laser scanners are line-of-sight instruments, so to ensure complete coverage of a structure, multiple scan positions are required. After scanning the result is a series of scans from different positions. These scans need to be aligned to a single coordinate system so that a complete point cloud model is made.


Examples where DelftTech used 3D laserscanning in civil projects are: highways, tunnels, buildings, terrain modeling, city modeling, surveying, check of structural elements, monitoring projects, etc.

Example Projects:

Hagestein bridge, Vianen.

Vianen crossroads are always very busy spots, but are also important arteries of the dutch infrastructure. Therefore, it is vital to keep these junctions under a perfect condition.

Several drivers reported back a wave sensation after crossing the Hagestein bridge. So it was decided to do a study of its deformation process over the last 4 years to find out why was this oscillation taking place. DelftTech compared the deformation pattern of a standard bridge with the Hagestein bridge.

Conclusions: torsion appears.
