Uncertainty associated with variability in geotechnical conditions, bedrock depth, cavities, fractured zones and faults must be reduced to ensure economic design, to avoid unforeseen construction difficulties and to protect the project from unwanted cost and delay. Geophysical investigations, including seismic methods, play a key role in providing the geo-data largely needed during the planning and design phases of the asset cycle. Indeed, measurements of seismic P and S wave velocity play an important role in the characterization of the near surface including stratigraphic mapping, detection of geohazards and the determination of geotechnical properties. Simultaneous P- and S-wave refraction investigation in steep terrain was carried out for a major infrastructure project in the Gulf region. Travel-time tomography was performed with P- and SH-wave first arrivals observed along survey lines to build P-wave and Swave velocity tomography models. A clustering process was then carried out to differentiate geological layers based on seismic velocity. We demonstrate that by combining inversion and clustering of seismic data, rapid and robust characterisation of the ground can be achieved to help manage ground-related risks.
