A workflow that links investigation to implementation
Our structured engineering workflow means you are supported through decision-making, installation and performance verification, not handed a standalone report.
The DAQ engineering cycle
Ten steps, applied in proportion to the problem. A small support query may pass quickly through several; a major study works through each in depth.
Site investigation
Desktop review, reconnaissance, pits and boreholes.
Geological assessment
Lithology, structure and groundwater.
Rock mass classification
RMR, Q and GSI from logging and mapping.
Geotechnical analysis
Empirical and kinematic assessment.
Numerical modelling
Where the mechanism demands it.
Engineering design
Support, layouts and slopes you can build.
Risk assessment
Consequence and exposure drive priorities.
Implementation support
On site during installation, with QA/QC.
Monitoring
Instruments and trigger levels verify the design.
Continuous improvement
Lessons fed into the next investigation.
Feedback loop: monitoring results and lessons learned feed directly into new site investigations.Engineering philosophy
Investigate, understand, model, design, implement, monitor.
Evidence-based engineering
Decisions supported by geological, geotechnical, structural and monitoring evidence.
Risk-based decisions
Resources directed at the mechanisms with the greatest consequence and exposure.
Practical design
A sound design must also be constructible with your mining method and equipment.
Operational integration
Geotechnics embedded in mine planning, not working alongside it.
Continuous verification
Ground behaviour checked against design assumptions, with controls updated as conditions change.
Failure investigations
When cracking, instability or unexpected ground behaviour occurs, we follow an evidence chain to the mechanism before recommending a remedy.
Applies to underground excavation failures, portal and decline instability, highwall failures, surface cracking and subsidence, and structures affected by blasting or groundwater.
Blast vibration and structural response
We combine blast-record review, PPV and airblast monitoring, waveform analysis, pre- and post-blast crack surveys and foundation investigation to separate blast-related damage from ground, construction and environmental causes, using measured evidence.
