Abstract A thorough understanding of the spatial distribution of geotechnical parameters in the subsoil is essential,
especially for site-specific risk assessment studies or construction projects. The uncertainty of interpolating the spatial distribution of geotechnical parameters can be reduced by applying seismic tomography between the CPT positions. In the  frame  of  the  R&D  project  CPTTOMO,  a  novel  CPT-based  tomography  system  has  been  developed.  This  system integrates  multi-station  three-component  geophones  as  well  as  P-  and  S-wave  sources  in  small-bore  Direct-Push  CPT rods. Results from test sites indicate that a joint recording and evaluation of geotechnical and seismic parameters improves the spatial representation and informative value of geotechnical data. The presentation introduces this novel system, shows one data example and highlights the potential for geotechnical subsurface investigation and site assessment.
