Day 1 on the Geotechnical Engineer path.

What a Geotechnical Engineer does

Tests and analyzes soil and rock so construction teams can build safe foundations, slopes, tunnels, and retaining walls.

  • Plan site investigations and choose where to drill, sample, and test soil and rock
  • Review lab and field results to estimate strength, settlement, and groundwater effects
  • Design foundation recommendations for buildings, bridges, and industrial structures
  • Assess slope stability and propose earthworks, retaining walls, or ground improvement
  • Write clear geotechnical reports with risks, assumptions, and construction guidance
  • Coordinate with civil and structural engineers to match designs to ground conditions
  • Support construction with inspections, monitoring data, and problem solving on site

A day in the life

  1. Check project plans, site logs, and safety notes before field or office work
  2. Analyze test data, update calculations, and draft recommendations for designs
  3. Meet with designers and contractors to explain ground risks and options
  4. Review monitoring results and adjust plans when conditions differ from expectations

Tools you will use

CAD: AutoCAD, Civil 3DGeotechnical software: PLAXIS, GeoStudioField testing: SPT, CPT, vane shearLab testing: triaxial, consolidation, sieve analysisSurvey and monitoring: inclinometers, piezometersSpreadsheets: Excel, Google Sheets
