Soil pressure and bedding modulus

Hello.
I had a soil report prepared. It says:

"To accommodate settlements / differential settlements up to 1.5 cm, a design value of the bearing pressure (EC 7) of 200 kN/m² can be assumed for an assumed effective foundation width of 1.0 m.
The floor slab is to be designed on the basis of an elastic bedding. For the design of the floor slab with a design value of the bearing pressure of 140 kN/m², a bedding modulus of 9.5 MN/m³ is to be used."

In my construction contract, the clause states:
"The calculation basis is an allowable bearing pressure of 150 kN/m² and a bedding modulus of 20 MN/m³."

What does this mean for me?

Hmm.... no one can help me further?

We are not your contractor. He can definitely tell you (or his structural engineer or similar) how expensive it might be..

Hello Saruss.
It is not about whether and how expensive it will be at first.
But what exactly that means.
Do I have a "soft" ground?
Does a ground replacement have to be carried out? etc.

See my answer. The structural engineer/construction contractor will be able to tell you what "requirements" your desired house in the desired location has and what needs to be done. The 2 values alone say nothing about all the accompanying circumstances (house requirements/ seismic zone etc. pp.). Just because the costs for a certain condition are fixed in the description, that does not mean the house actually requires them. Only that the contractor may charge a surcharge in case of deviations (in a negative direction). The soil pressure is somewhat worse.

hmm.... I signed the building contract today......and the seller couldn't tell me anything about the [Baugrundgutachten]. I should wait until the construction management/structural engineering looks at it... I have a bad feeling
