Design audits of civil, open pit, tailings and mine waste landforms and closure designs. We also undertake review, investigation and back analyses of failures or areas with significant.
A particular feature of 3RC’s approach is the use of quantitative geotechnical risk assessment procedures and practice, a high-level approach that provides management with the information it needs to assess the safety and economic implications of geotechnical designs. This provides a rational basis for the assessment and optimisation of our clients mine designs, ultimately producing maximum stakeholder value.
