How to become a geo-technical engineer

To become a Geotechnical Engineer you will need specific qualifications, which are offered by a limited number of UK universities.

To get onto a degree course, you need GCSE and A-level grades A*-C or equivalent such as Scottish Nationals or Highers, or the Welsh Baccalaureate. Relevant degree subjects include Geology, Geophysics/geotechnology, Engineering geology, and Mineral/mining engineering.

There are a number of first degree geoscience courses accredited by the Geological Society. By completing an accredited degree, you usually qualify for membership (Fellowship) of the society after gaining relevant postgraduate experience. This is also the route to become a chartered geologist (CGeol), after a period of professional development and experience.

If you have a background in civil engineering or the sciences, it is sometimes possible to enter the field through the Institution of Civil Engineers (ICE) or the Institute of Materials, Minerals and Mining (IOM3).

A postgraduate qualification, such as a Masters (MSc) in engineering geology, geotechnical engineering, hydrogeology, soil or rock mechanics, or foundation engineering is desirable.  An accreditation scheme for taught postgraduate MSc courses is also available.
