STRABAG revolutionizes surveying with NavVis technology

Eric Skrzeczek's team is deployed in particular for the preservation of evidence and documentation of STRABAG construction sites in civil engineering. Approximately one week before construction begins on a project, the team is notified of the specific area on the construction site where evidence preservation is needed and promptly carries out the required work. Once the construction work has been completed, the same area is surveyed again. With NavVis VLX, up to 12 streets can be surveyed in a single day, with the team setting up 3 control points for each street. That's quite impressive. We could probably do even more, but we only have three battery packs,” says Eric Skrzeczek.

Eric Skrzeczek sees the main application in the creation of as-built documentation as well as billing and boundary plans: “We also carry out classic surveying tasks, and we can do this much faster with the device.” He is also impressed by the data quality of the point cloud. Thanks to the high point density, once the data has been processed in NavVis IVION, it can be further processed and partially analyzed automatically using additional software. According to Eric Skrzeczek, the software recognizes broken edges in NavVis data - such as curbs or buildings - very quickly, around 50-100 m of route data in just a few seconds.

Surveying work using conventional methods is particularly difficult at complex traffic junctions. In most cases, the areas in question have to be blocked off extensively to enable surveyors to collect the desired data. However, this inevitably results in road traffic obstructions, project delays, and increased costs. With NavVis VLX, however, such downtimes can be reduced or even avoided altogether, as the device not only scans extremely quickly, but also very flexibly.

The scanning of a junction, for example - normally associated with costly road closures - can be completed conveniently with the wearable laser scanning system within a very short period of time and without restricting traffic. This eliminates the costs of road closures and additional traffic safety measures in particular. Eric Skrzeczek and his team were able to scan a large intersection, which also included a tram line and a bridge, in just two hours. “This allows us to shorten closure times, which of course also makes out client happy. This is also a point where we can set ourselves apart from other companies,” says Eric Skrzeczek.
