Manual monitoring
Periodic precision measurements by a surveyor-expert.
Not every project requires a permanent setup. With manual monitoring, our surveyor-expert visits the site at fixed intervals to track the evolution of measurement points using levelling, total station or GNSS — cost-efficient and with the same high precision.
When to choose manual monitoring?
Manual monitoring is ideal when movement is slow or a lower frequency is sufficient. It is the most cost-efficient solution for projects with a limited risk profile or a short duration.
- Settlement measurements by precision levelling (down to 0.2 mm/km)
- Periodic 3D measurements of fixed survey bolts
- Levelling bolts and survey nails on façades and infrastructure
- Independent verification of automatic systems
Clear reporting
After each campaign you receive a report with the measured values, the differences relative to the zero measurement and a clear visualisation. If a threshold is exceeded, we notify you immediately.
As a surveyor-expert, our reports carry legal evidentiary value, which is important for condition surveys and liability files.
Applications
- Building settlement tracking
- Condition surveys near works
- Verification of automatic systems
- Long-term, slowly evolving movements
