Independent Design check of a high level viaduct structure across steep mountainous terrain, in a seismically active region. The foundations comprised unusually large diameter caisson structures, founded on a foliated gneiss. Foliation within the gneiss was locally adverse. A detailed appraisal of all available geotechnical data including outcrop was undertaken and assessment of overall and local slope stability evaluated in relation to the bearing capacity potential for the foundations.
