Tunnel Monitoring Systems

The Tunnel Profile Monitoring System consists of a series of inclinometers mounted in the concrete of the tunnel wall. The system can be used both to measure the impact of nearby construction on existing tunnels, and to measure deformations that may occur in tunnel walls immediately after excavation by mounting on precast segments during TBM excavation.

The system can be connected to a data acquisition or Geoviewer system to provide graphical near real-time displacement and tunnel profile information.
