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.
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.
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.
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.
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.
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.
The shallow subsurface has a constant temperature that is warmer in the winter and colder in the summer than the outside air. Using heat pumps, the constant temperature of the substrate can be used to warm and cool houses and buildings. This is called aquifer thermal energy storage (ATES). These applications usually do not go deeper than 150 m.
The deeper subsoil (more than 1 kilometre) is used in the Netherlands to extract hot water to heat greenhouses. This is called geothermal energy. There are several concrete plans to use geothermal energy for district heating. There are also plans to use ultra-deep geothermal energy (more than 4 kilometres deep) for industrial heat.
