Construction & Tunnelling
Monitoring
Real-time deformation, convergence and vibration control during deep excavation, tunnelling and high-rise construction phases.
Why Construction
Monitoring Matters
Construction and tunnelling projects involve significant ground disturbance, creating risks for nearby structures and workers. Real-time monitoring of ground movement, vibration levels, and structural response is critical for safe and compliant project delivery.
Sentra's wireless IoT sensors provide continuous visibility into excavation stability, tunnel convergence, and construction-induced vibrations — enabling immediate response to developing risks and protecting adjacent infrastructure.
Key Monitoring Parameters
- Tunnel convergence and lining deformation
- Deep excavation wall deflection
- Ground settlement and heave monitoring
- Construction-induced vibration tracking
- Adjacent building tilt and displacement
- Groundwater level and pore pressure

Frequently Asked Questions
A tunnel monitoring system typically combines tiltmeters for lining rotation and convergence, GNSS or prism-based sensors for surface settlement above the alignment, and vibration meters to track ground-borne vibration from excavation and blasting works.
Wireless vibration meters are mounted on or near adjacent structures to continuously log peak particle velocity, comparing readings against regulatory or contractual thresholds and triggering an alert the moment a limit is approached.
Alerts are configurable per sensor, movement beyond a set tilt or displacement threshold, vibration exceeding a peak particle velocity limit, or a rate-of-change that suggests accelerating ground movement all generate immediate notifications to the project team.
