Monitoring the ground for the new E18
Cautus Geo is monitoring the ground for the new E18 motorway - "Crucial safety measures," say geotechnical engineer Marte Sundby Nybo and project manager Mariusz Wozniak at the Norwegian Public Roads Administration.
Problem statement
The ground conditions for the new E18 motorway from Lysaker to Ramstadsletta consist of a lot of soft clay soil. Depths to rock vary and there is a lot of infrastructure in the ground. Traffic must be as unimpeded as possible.
Solution
Initially, Cautus Geo installed around 50 pore pressure gauges in the ground. This was later expanded to a total of 179 from Lysaker to Ramstad, which monitor the groundwater in real time. Data can be read and displayed in Cautus Web in real time. It's all set up with alerts.
Many people live and work close to the site. The project managers for the new motorway have a lot to look after.
SVV's organisation on the E18 project has 70 employees. In addition, there are many external employees from various subcontractors. Many of them need to be informed about Cautus Web alerts about changes in pore pressure and groundwater that can cause subsidence damage to buildings and infrastructure.
Many neighbours of the road facility are directly affected. Several meters are installed in private gardens and driveways.
It's about preventing subsidence damage to buildings and properties.
Heavily trafficked
The E18 west of Oslo is one of the country's busiest roads. 90,000 vehicles pass every day.
The E18 must work. Cars have to get there, and during the construction period several diversions are planned that will affect traffic in both directions for many years.
The large construction site is an important workplace for Cautus Geo. In addition to groundwater monitoring, Cautus Geo is involved in the area through the KlimaGrunn research project and other projects close to the construction work on the new E18 motorway.

Technology
"Cautus Geo's solution with Cautus Web is absolutely crucial. It allows us to read the pore pressure where we are. In addition, the system is set up with alerts. If something happens to the pore pressure/groundwater, the alarm goes off and many people are alerted at the same time.
