Geotechnical Site Investigation and Soil Mechanics Training Course (Online / Remote)
1Summary
Every foundation, retaining wall, and earthworks project stands or falls on what lies beneath the surface, yet ground conditions are often the least understood variable in a construction plan. This Arab British Fellowship Training Academy course puts geotechnical site investigation at the centre, then builds the soil mechanics knowledge engineers need to interpret what that investigation reveals.
Participants move from field practice, sampling, in-situ testing, and investigation planning, into the mechanics that make sense of the results: soil classification, shear strength, settlement behaviour, and permeability. The course closes with how modern geophysical and remote-sensing tools are changing site characterisation, leaving engineers with a practical, decision-ready view of subsurface risk.
2Objectives and target group
Who Should Attend?
- Geotechnical and civil engineers responsible for site investigations and foundation design.
- Engineering geologists and field technicians collecting subsurface data.
- Construction managers and supervisors overseeing ground works.
- Consultants and contractors delivering geotechnical scopes of work.
Knowledge and Benefits:
By the end of the course, participants will be able to:
- Plan a geotechnical site investigation, from desk study through borehole and sampling strategy.
- Apply standard and advanced in-situ tests (SPT, CPT, plate load, vane shear) and interpret their results.
- Classify soils and evaluate their index, compaction, and shear strength properties.
- Analyse stress distribution and predict settlement for foundation design.
- Turn laboratory and field data into reliable geotechnical reports and design inputs.
- Recognise where geophysical and remote-sensing methods add value to a site investigation.
