We’re proud to play our role in monitoring highways and infrastructure assets across the UK.
Just some of our live monitored assets include:
- Bridges
- Retaining walls
- Sea defences
- Embankments and rock faces
- Offshore wind turbine foundations
- Rail tracks
- Temporary works and construction sites
- Tall buildings and Towers
- Tunnels
With SAMS™ , information and data can be collected from any acquisition units or sensors that communicate broadband internet or 4G mobile phone signal. All data is streamed real-time for live reporting and can even be viewed from a web browser! Information is processed, analysed and displayed to inform decision making, as well as to give you useful visualisations.

Sensing can include:
- Displacements and rotations
- Strains using resistance or vibrating wire gauges
- Acceleration and vibration
- Fibre optic gauges, for strains, temperature, displacements, tilt and accelerations
- Foundation movements and settlement
- Corrosion progression
- Weather conditions, including temperature, wind speed/direction, humidity
- Weight-in-motion vehicle loads
- 3D positioning by automated total stations
- GNSS (satellite) 3D positioning
- Ice detection
Short term monitoring applications can be used as a “design validation” exercise or for a snapshot of the structure’s performance. Carrying out controlled load tests or measurements in-service can find various possible faults, including: measurement of in-situ stress, bearing seizure, loads in tensioned cables, capacity of parapets and response to excitation.
We are at the forefront of technological implementation for structural health monitoring on bridges and other assets.
Projects
Our work with the University of Surrey has conducted research into the U-frame behaviour in abnormal girders, monitoring displacements and strains, both under live trains and controlled loading.
Monitoring on the Queensferry Crossing has (to our knowledge) the most sensors on any bridge in the world at over 2300.
Smartbridge continues research into an adaptive automated finite element model creating a digital twin where the model adjusts to represent real readings and measurements which can be calculated from the model for areas where no sensors are installed.
The bridge monitoring system at Pont de Normandie includes data collected by a total of 20 high speed data acquisition units, 3 meteorological stations and 17 GNSS units, which all send to SAMS™ for comprehensive processing, creating one user interface regardless of the sensory system, data type and who installed it.
