Deformation monitoring in the ground

For the client Østfold Energi we have recently installed SAAF deformation sensor (field array) in vertical boreholes for continuous web monitoring. The energy wells were drilled for a new hospital in Østfold, Norway, and the purpose is to monitor the stability in the soil while the constructiion work is ongoing. The ground consists of clay, and the SAAF’s are drilled down to rock for reference.
Løvlien Georåd is the geotechnical consultant and Cowi are managing the project. Project participants may monitor ground movements at any time using Cautus Web and will receive an alarm if any thresholds are exceeded.
