Tunnels And Metro
Tunnel and metro works combine deep excavation, cable-dense plant rooms and alarm thresholds that must be met on a live programme.
Pain Points
What Goes Wrong On These Projects
- Manual probe surveys that miss movement between site visits
- Tight boreholes where standard couplings hang up
- Cable fire risk in confined tunnel environments
- Data arriving too late to act on an active excavation
Customer Needs
What The Work Actually Requires
- Automated in place inclinometer strings with RS485 output
- Flush coupled casing for tight annulus
- Fireproof cable wrapping for tunnel cable routes
- Strain gauges on linings and supports
