Finite element analysis and computational fluid dynamics often form a key part of the design process.
We collaborate with project consultant teams to devise and carry out full-scale testing to validate this analysis, typically on a worst-case scenario.
Trials can include, for example, simulating millions of trains passes; accelerated durability testing to represent up 120 years life.
Testing is closely monitored. Measurement instrumentation includes:
- Strain gauges
- Accelerometers
- Thermocouples
- Flowmeters
- Displacement transducers
- Load cells
Measurements are recorded by data loggers (up to 150 channels) and can gather over two billion bits of information.
Recent projects

- HS2 – Fatigue testing of noise barriers
- Cross-passage Safety Doors – Mirroring forces on the doors incurred by train passes
