A basement (excavation)?
With material, for example for the crane setup area, the surface for the foundation slab?

Yes, a basement.
The material is included in the fixed price of the general contractor.

Can anyone estimate how much the earthworks might cost or share their experiences? How is it calculated?

Who are you building with? A general contractor (GC) or an architect? Many turnkey homes often include a line item for earthworks, aggregate base, and similar tasks. However, this varies from one GC to another.

Our additional cost (without a basement) is around €10,000 but includes construction road, wastewater and stormwater drainage up to the handover shafts, and so on. Not included in the house price were: extra earthworks due to the sloped site, a larger excavator needed because of soil type with stones, more aggregate base, excavation for a double garage next to the house, aggregate base for the construction road and later garage subbase, and all the piping: water, wastewater, empty conduits for utilities, etc.

Not included in the house price were: extra earthworks due to the slope, a larger excavator because of the soil type with stones, more crushed stone, excavation for a double garage next to the house, crushed stone for the construction road and later garage base, and all the piping: water, wastewater, empty conduits for utilities, etc.

So the total additional cost was €10,000?
To what extent did your extra work related to the slope involve?

That’s hard to say, as there is always just one item for extra excavation and additional materials, with part of it allocated for the garage, part for extending the shafts, and part for extra effort compared to the construction specifications. The slope on our site is relatively mild, with about 0.80m (31 inches) difference in elevation along the length of the house. However, we had a very "favorable" soil report, which basically stated: "Remove topsoil, then just scrape away the loose material, that’s sufficient." There are also soil reports where you first have to excavate 1.20m (47 inches) deep, regardless of the planned height of the house.
