SkyTEM Geotechnical Survey in Norway
SkyTEM Surveys has successfully completed a geotechnical survey in Norway for NGI (Norges Geotekniske Institutt). For the first time in Norway, airborne electromagnetic (AEM) measurements have been used to support geotechnical investigations for the design of a new stretch of motorway. The investigated road is a major WE-connection, E16 passing Oslo Airport and heading East towards Kongsvinger and further into Sweden. Some 50 km North-East of Oslo, 32 km of E16 between Nybakk and Slomarka are scheduled for upgrading from two lanes to four lanes, and for this project NGI serves as a geotechnical consultant to COWI as the main contractor for the Norwegian road authorities (Statens vegvesenet).
The SkyTEM AEM survey scanned the subsurface several hundred metres deep. The expected deliverables are bedrock topography and quick clay extent – both never mapped with AEM in Norway before.
