Generational gaps in geotechnics? A transalpine perspective

Abstract

Geotechnical engineering is a challenging profession and offers exciting working opportunities. However, in recent years, it struggled to attract young talents. While shifting life and work values are frequently given as contributing factors, empirical evidence to support this claim remains scarce. In view of that, an international online survey was conducted from March to July 2025 to explore generational differences in experiences, beliefs, needs, and goals of members of the applied geo-community. The survey targeted professionals of all ages who study or work in geotechnics or other applied geo-related disciplines. This article focuses on the responses from Austria, Germany, and Switzerland. The results do not suggest that there is a consistent generational gap. While there are certain differences about some topics (e.g., conflicts with younger generations rather revolve around work-life balance and priorities but with older generations more around authority and decision-making), many questions show strong agreement between generations (e.g., finding meaning and fulfilment in the job is more important than income). The results serve as a foundation for increasing the profession's attractiveness, offer valuable insights into intergenerational biases, and lay the groundwork for improved collaboration in the workplace.
