Funded as part of the EU response to the COVID-19 pandemic


Our passion:
dynamic analysis, vibrations, para-seismic vibrations

We analyze:
- dynamic loads acting on structures from:
- moving metro vehicles, trains, trams
- machines (turbine sets, fans, pumps)
- mining tremors

We will help you with:
- checking the safety of existing structures and even those in the design phase in the vicinity of a metro tunnel, tram or railway track
- checking the safety of existing structures and even those in the design phase in the vicinity of mines
- designing foundations for machines
- in situ measurement of vibrations / accelerations or simulation of these vibrations (any source of vibrations)
- the selection of vibration isolation / construction changes due to additional dynamic excitation


- Dynamic analysis/ vibration analysis resulting from para-seismic influences (vehicle vibrations, mining tremors)

- Design of a foundation for a machine

- Selection of vibration isolation / mats / damping pads

- In situ vibration measurements

- Assessment of the precision of plans / Expertise

- Advice / consultation
