Engineering Methodology
Structured engineering workflow for geohazard assessment, slope stability analysis and risk-based mitigation design.
Engineering Workflow
01
Site Reconnaissance & Data Collection
Initial site visit, structural mapping and geomorphological interpretation.
– Rock mass inspection
– Discontinuity survey
– Drone / photogrammetry data
– Preliminary hazard identification
02
Engineering Geological Mapping
Engineering geological mapping and slope zoning to define controlling factors and domains.
– Lithological units & weathering grades
– Structural domains / discontinuity sets
– Kinematic assessment (planar/wedge/toppling)
– GIS-based zoning & constraints survey– Drone / photogrammetry data
– Preliminary hazard identification
03
Geotechnical Characterisation
Derivation of design parameters based on field data, testing and empirical correlations.
– Rock mass classification (GSI / RMR)
– Joint properties (roughness, infill, persistence)
– Strength parameters (UCS / Hoek–Brown / Mohr–Coulomb)
– Hydrogeological conditions
04
Modelling & Scenario Analysis
Numerical and/or empirical modelling to test failure mechanisms and rockfall trajectories.
– Slope stability (LE / numerical methods where applicable)
– Rockfall trajectory simulations & calibration
– Sensitivity analysis
– Scenario-based evaluation
05
Risk Evaluation
Integration of hazard, exposure and consequences to support decision-making.
– Hazard frequency & intensity
– Elements at risk (assets / infrastructure)
– Vulnerability and consequence levels
– Risk matrix / prioritisation
06
Mitigation & Monitoring Strategy
Selection of feasible mitigation measures and monitoring where required.
– Passive protection (barriers, fences, ditches)
– Active stabilisation (bolting, mesh, shotcrete)
– Drainage and surface protection
– Monitoring plan (inspection / instrumentation)
