Subsoil investigation and geotechnical report for foundation

Hello everyone, I have an offer here for the above-mentioned work and wonder if it is fair, it somehow seems too much to me :( and it is supposed to cost €1755.25 including VAT. What did you pay for it? Thanks in advance. P.s. It is supposed to be a simple single-family house built with a garage, on a slab without a basement. The plot is flat, it was previously a green meadow.

Unclear what exactly this is :D
we paid about 600 € for a soil survey with foundation recommendation.
Has it already been decided where the house should go? It may also depend somewhat on the conditions and yours sounds like more than just drilling.

Here is the offer

Hello, I have now obtained a few more offers, yikes the prices fluctuate significantly, one wanted to do it for €600 (only two drillings) the other for €950 (comparable to the offer listed above) the middle ground received the order. What is a bit strange is that the most expensive one was from the same town, doesn’t even have to drive 4km to the property, the other two come from about 60km away. So "comparison makes rich" has proven itself once again.

Hello, together with our semi-detached house neighbors we paid 1178 €. This included, among other things, 3 driven core drillings to a final depth of 6m and 3 heavy driven core drillings.
