Geotechnical and hydrogeological uncertainties can substantially increase construction time and cost if risks are not identified and mitigated at an early stage. Cases of failure could result in expensive rework, project delays and reputation damage. Stakeholders therefore require a high level of expertise to determine the right analyses and measures to ensure that projects proceed smoothly and safely.
TÜV SÜD’s hydrogeological and geotechnical advisors can help you assess the condition of your building or infrastructure project prior to construction and define how your construction can accommodate such conditions with minimal costs in the safest, most efficient manner.
What hydrogeological and geotechnical advisors do
In order to proceed with a construction project, the foundations of a designated building area must be certified as both safe and economical. Load-bearing capacities, stability, groundwater conditions or the possibility of a contaminated building area are only a few aspects of hydrogeological and geotechnical engineering that determine the interaction between the subsoil and a built structure.
Different aspects of geotechnics play a role in all types of structure, whether on the surface (e.g. buildings, wind turbines) or underground (e.g. tunnels) or from the soil material itself (e.g. dykes). The risks associated with construction projects can be very costly if left unmitigated. That is why developers, owners, operators and contractors of buildings and infrastructure must ensure the safety and performance of their projects.
It is important to gather relevant and accurate data about the essential features of the infrastructure being built or already completed to mitigate the risks and provide technical and legal certainty for project stakeholders. This is where TÜV SÜD’s geotechnical engineering services and hydrogeological advisors can help.
TÜV SÜD can support you in a wide variety of geotechnical engineering tasks. Rely on an experienced partner and use our geotechnical know-how for your project. Using the latest technologies, we develop personalized solution concepts for your problems and get the job done.
