Expert consultancy in subsurface, vibrations and earthquakes.

Top specialists with an end-to-end view

Knowledge

We are specialists in the field of structural dynamics, vibrations, earthquakes, geology and geotechnics. These knowledge fields are all too often applied independently. We bring them together. By bringing together the different disciplines we tackle complicated, but also seemingly less complicated problems adequately.

Coherence

In our consultancy services we look for coherence between our technical advice and the bigger picture of our clients. We also look for coherence between different technical disciplines. In case of abundance of digital information, it requires specialist knowledge and an end-to-end view to come up with an optimal advice. This is what we are good at.

Result-driven

A quick understanding of problems based on much or very little data is our strength. We translate data into information and make models to come up with predictions. We subsequently check the predictions on the basis of monitoring data. This closes the loop. We are used to working efficiently and result-driven.

Co-operation

Our consultants have top specialist knowledge. We see great added value when this knowledge is part of an integral advice. By working with other specialists our own advice becomes stronger. We bring different experts together to provide the best advice to our clients.

Services

Subsurface

The subsurface is the most uncertain factor in projects. For the design of foundations, vibration predictions or the determination of earthquake load, the behaviour of the subsurface plays an important role.

The subsurface is not transparent. We are therefore dependent on (CPT) soundings, boreholes or geophysics to map the ground.

When interpreting and connecting all this information, it is necessary to understand geology, geotechnics as well as foundation techniques.

Vibrations

Vibration is the movement of a structure or medium. The way a structure or medium vibrates is sometimes difficult to predict. Damage or hindrance can be unwanted consequences of vibration.

By performing vibration monitoring we can get understanding of the level of vibration and its consequences. This needs in-depth knowledge of monitoring, data processing and assessment criteria.

In case of assessing future situations, we need to make use of prediction models. This requires knowledge of the different modelling techniques.

Earthquakes

Anyone who has experienced an earthquake can confirm it has a huge impact. The impact can be in the form of damage to buildings and structures, but also in the form of social unrest.

Therefore seismic design is important for buildings and structures in earthquake sensitive areas. Determining earthquake loads and especially their uncertainties is not that simple.

Knowledge of the deep and shallow subsurface is required. Also knowledge is required of seismic processes, wave propagation in the subsurface and soil-structure interaction. Statistics is needed to deal with the uncertainties.
