Often the life cycle of constructions is monitored. Examples of this are the extensive instrumentation of earthfill dams in Norway, large bridges and offshore platforms and installations. The measurement systems are operative from the building and installation phase and also used to monitor constructions during their whole lifetime under all weather conditions.
Use of instrumentation
Other areas in which our knowledge of instrumentation is used include measurement, monitoring and advance warnings:
- ground water pressure (pore pressure)
- natural disasters resulting from from tremors and rock slides
- contamination of soil and groundwater
- vibrations and noise from traffic
- local weather and climate conditions
- special investigations of ground conditions in soil and rock
- gas leaks from and on the seabed
- precise measurements for pre-installed foundations, allowing constructions to be produced with accurate measurements matching the foundation
Research and development
Research effort in instrumentation is currently focused on new and better solutions for wireless monitoring. New research in remote monitoring, in which satellites continuously send data to measuring stations, allows effective monitoring of larger areas over greater distances.
In addition, we are working on:
- development of monitoring systems for physical processes in nature
- use of fibre-optic measurement methods and microseismic monitoring of soil slides in tunnels
- use of satellite radar data for soil and rock slide assessment and monitoring of large buildings.
