ᐅ What should we consider when reviewing a soil survey?

Hello dear community,

we are about to have a soil survey carried out for our plot of land.
We have requested several quotes and received very different prices and approaches.
They ranged from 950 to 2600 euros.
Unfortunately, we have no experience with this topic and wonder what is important when it comes to a soil survey?
Dynamic probing, small boreholes, excavation pits?

We look forward to your feedback.

Thank you very much!

Best regards

For a single-family house, two boreholes at the edges of the building plot are sufficient. About five meters (16 feet) deep.

Hello Nordlys,

thank you for your quick reply. We also received an offer for 4 m (13 feet) excavation trenches. What do you think about that?
The most affordable offer includes 2 small boreholes, a geotechnical report, and a comprehensive building recommendation. Is that enough?

Best regards

We only conducted small boreholes plus core analysis and then received foundation recommendations for options with and without a basement. Our builder did not expect anything else.

In December, we also had a geotechnical engineer on site; it cost around 700 €.

This included two dynamic probing tests with hydrogeological analysis, foundation recommendations, and so on.

There were also two dynamic cone penetration tests, including hydrogeological analysis, foundation recommendations, and so on.

What was included in the offer? Are you from Bavaria? Would you recommend them to us?
