Engineering geological site investigation for linear infrastructure on soft soil

The Geo-Impulse project Reliable Subsurface Model aims at a 50% reduction of failure costs in civil engineering works due to poor subsurface modelling. The current Dutch approach towards site investigation for linear infrastructure almost completely ignores geological factors. The Total Engineering Geology Approach4 is shown to be a suitable basis for an improved approach, integrating geology, remote sensing and geophysics. Expert knowledge can be made available to non-expert end users by two methods available at TNO-NITG and Deltares.
