The world is changing quickly by new technologies. Technologies meant to make our lives easier, to increase safety and to gather all kinds of information. To make the right decision based on facts you need the right knowledge and understanding. Technical specialists with profound understanding of their field are needed. Our mission is to contribute to society by giving solid advice through expert consultancy.
Our expertise is in subsurface, vibrations and earthquakes. 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.
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 of approximately 15 degrees. With heat pumps, the constant temperature of the subsurface can be used to heat and cool houses and buildings. This is called aquifer thermal energy storage (ATES). These applications usually do not go any deeper than 150 m.
The deeper subsurface (more than 1 kilometer) is used in the Netherlands to extract hot water in order to heat greenhouses. These are called geothermal systems. There are several plans to use geothermal systems for district heating as well. There are also plans to use ultra-deep geothermal systems (more than 4 kilometers deep) for industrial heating and residual heat for district heating.

Together with Railway Operator ProRail, Cohere Consultants will give a presentation on the recent guideline new building constructions and railway vibrations. The presentation will be given on the 6th of November during the Dutch National Congress on Noise, Vibrations and Air Quality, see GTL congres. Next to that Eliam will chair the session on vibrations on behalf of the Dutch Vibration Association.
