Stress characterisation is important to design and critical decision making. Uniformity in the in situ stress state of rock mass is rare; its distribution depends largely on geological structure and loading history. A successful measurement campaign is not limited to acquiring point measurements but also must include a prudent examination and integration of available data, observations, and relevant site information. This talk will cover a brieft review of the most common field measurements employed in practice, including those used by MIRARCO's Geomechanics Research Centre, and the approach used to ascertain a best approximation in addition to highlighting the challenges faced.
