Frequently asked questions
- Who should carry out excavation risk assessments?
- A competent person with knowledge of excavation hazards, soil types, and support systems. For deep or complex excavations, input from a temporary works designer or geotechnical engineer should be sought.
- How often should excavations be inspected?
- At the start of each shift, after any event likely to have affected stability (heavy rain, vibration, surcharge loading), and after any fall of material. A competent person must carry out inspections and record the results.
- What about services in deep excavations?
- As excavation depth increases, the likelihood of encountering services at non-standard depths increases. Your risk assessment should specify detection methods and confirm that service records have been obtained from all asset owners before excavation begins.
