Data from Insar satellite measurements is to be used to monitor displacements during construction of the E18 motorway near Oslo.
Norwegian roads authority Staten Vegvesen will work with the Norwegian Geotechnical Institute (NGI) and its consultant Aas-Jakobsen to use the system to monitor movement and ground displacement with millimetre accuracy before, during and after construction.
“With this innovative method we will get detailed knowledge about movements in the ground due to construction of the E18,” said Staten Vegvesen project manager Grete Tvedt. “Displacements or ground movement may cause damage to nearby houses and dwellings. If such movements are detected at an early stage it will reduce the risk for costly mitigation. This will provide greater security for the citizens, and in the long term, we hope to save substantial amounts.”
