Does excavation need geotechnical supervision on a genuinely unstable site?

Yes — on a site with genuinely identified instability risk (steep slopes, known landslip areas, poor soil), a geotechnical engineer may need to inspect during excavation to confirm conditions match what was expected and the work remains safe.

Your soil report and engineering design flag whether this genuine level of oversight is required for your specific site.
