With its extensive expertise and experience in the area of surveying, positioning and dimensional control, Geocon is revered in Europe. Geocon is specialised in supplying position data while tunnel elements are being immersed and caissons are being positioned.

Geocon is also the name of the software that uses a variety of advanced survey and positioning systems to follow objects in three dimensions. The measurement data are translated into position data in coordinates. Highly advanced software also provides on-line graphic images of the structure being moved. This means that immersion information can be transmitted throughout the world via the Internet.
