Geotechnical risks are as varied as the geologic conditions that create the hazard that is the source of the risk, and the types of construction. No construction project is risk free. Risk can be managed, minimised, shared, transferred or accepted. It cannot be ignored.

Geotechnical risk is the combination of the chance or likelihood of an event occurring and the consequences of that event. Thus for example, high risk could be a result of a high probability of something occurring with a medium consequence (often cost). Geotechnical risk can also be understood in terms of the geotechnical hazard (e.g. liquefiable soil which is a source of risk) which is not related to the engineering design, and the vulnerability of a design to the hazard (i.e. the likelihood that a hazard such as liquefaction will produce unfavourable consequences with that particular design). For further discussion on geotechnical risk see “Managing Geotechnical Risk” white paper (White Papers).

Formal decision analysis is a powerful tool to enable project managers to make good decisions to manage risk.
