What is a Geotechnical Survey?
A geotechnical survey involves a geological investigation that describes the soil properties at a specific construction site. It provides information on soil load-bearing capacity, soil types, groundwater conditions, and potential risks such as settlement or landslides. The survey is a crucial basis for planning foundations, substructures, and other construction measures. It evaluates how the soil interacts with the planned structures and identifies any special requirements for construction execution.

FAQ
1. What are the costs of a geotechnical survey?
Costs depend on the size of the construction site, depth of investigation, and project complexity. We provide a customized quote covering all necessary examinations and analyses.
2. How long does it take to prepare a geotechnical report?
The process usually takes a few weeks, depending on geological conditions and required investigation depth. In simpler cases, the report can be completed more quickly.
3. What information is needed for the report?
We require details about the construction site, including location, intended use, and construction details. Existing soil information or previous construction data can also be helpful.
4. Why is a geotechnical survey important for my project?
A soil investigation ensures that the foundation and substructure are properly designed for the ground conditions. It prevents costly modifications and ensures that the building stands on a stable base. Poorly planned foundations can lead to settlement and structural damage.
5. Can a geotechnical report be modified later?
Yes, if changes occur during the construction phase, such as modifications to the building plans or unexpected soil conditions, the report can be adjusted. We assist in implementing all necessary modifications to keep your project on track.
6. Is a geotechnical survey required for every construction project?
A geotechnical survey is essential for all new buildings and major renovations, especially when building on unknown or difficult soils. We can advise whether a survey is required for your specific project.
7. Who conducts the geotechnical survey?
The survey is carried out by experienced geotechnical engineers and soil mechanics specialists. We collaborate with renowned expert firms to provide a reliable and well-founded report.
