Overall, the biggest challenge was to put in the foundations for
the bridges and roadway. Instead of replacing the swamp masses
or constructing a larger bridge over the swamp area, a network
of around 2,000 lime cement columns was created to stabilize
the soil. Even if the solution is invisible, it still provides a stable
surface for the road. The solution also helped CO2 emissions to
be more than 30 per cent lower as compared to traditional road
construction.
"It's been important for us to find ways of working that ensure
that we have secure interfaces, between technologies and people,"
says Bjørvik. "Due to the varying ground conditions, geotechnics
must be the starting point. Those teams deliver data as input for
the structural engineers so they can start the process of finding
out what is optimal in terms of cost, CO2 emissions and health &
safety," he continues.
