Know what the ground can tell you
Every structure transfers loads into the ground. Before a design is settled, the project team needs evidence about the materials below the site, how they vary, and whether groundwater or other conditions may affect the work.
A geotechnical investigation brings together available site information, field exploration and laboratory testing. The methods and depth of investigation should match the project, the ground conditions and the decisions the design team needs to make.
Turn observations into design inputs
Field work can include trial pits, boreholes, sampling and in-situ tests. Laboratory tests then help describe selected engineering properties. Together, these results support a ground model and recommendations that the project’s qualified design professionals can review.
The value is practical: a better basis for selecting foundation concepts, planning excavations, anticipating ground risks and preparing realistic construction requirements. Investigation findings reduce uncertainty; they do not remove the need for engineering judgement as work progresses.
Plan the investigation around the project
Share the proposed building or infrastructure layout, anticipated loads, levels and project stage with the geotechnical team. That context helps focus the investigation on the questions that matter and makes the resulting report more useful to the wider design team.
This guide shares general engineering context. Project requirements and design decisions should be assessed by the responsible professionals for each site and brief.
