Argeo was contracted by Multiconsult and Nye Veier to image construction area for the new bridge over Mjøsa lake
“Mjøsa is Norway’s largest lake spanning a total of 365 square kilometers, additionally it is also Europe’s 4’th deepest lake with a maximum depth of more than 300 meters. Using modern technology and 3D modelling software to reduce construction risks is essential in such a complex project.” – Nye Veier
In conjunction with the planning of a new bridge across Mjøsa, and new E6, Argeo has acquired multi-method geophysical and hydrographical data to improve the understanding of the lakebed and gain insight into the subsurface. UHR-multichannel reflection seismic, refraction-seismic, Multichannel Analysis of Surface Waves, and MBES surveys were conducted with the use of autonomous vehicles.
The acquired geophysical data were combined with drilling results and geotechnical data, and delivered as an integrated multidimensional subsurface model. The depth-converted surfaces (3D layers) derived from joint analysis and interpretation of the acquired data can be imported into most modern CAD design or Geosuite software systems to form a GEOBIM 3D construction foundation. The results provide an actionable digital model with the construction grade of accuracy that enables to better understand the subsurface and minimize potential risks.
