Hello everyone,
I need your advice.
We have found a plot of land near Regensburg with a developer tie-in.
The offer includes a slab-on-grade foundation without a basement, valued at €25,000.
Alternatively, we requested a quote for a waterproof basement (WU) priced at €1,200 per square meter (including the ceiling).
Additionally, there are €18,000 for excavation work related to the basement.
With a basement area of 60 square meters, this would amount to €72,000.
So our costs would be:
€72,000 for the waterproof basement
€18,000 for excavation (soil class 6)
€25,000 for the slab-on-grade foundation
= €115,000 for the complete 60 square meter basement.
Is this realistic?
Best regards

What about transporting the excavated soil? That should at least be included in the additional construction costs when comparing slab-on-grade versus basement.No, it just says earthworks. So disposal is included in that.Basement costs usually include the concrete slab.
For comparison, we recently signed a contract and are paying €83,000 for a waterproof concrete shell (“white tank”) with about 106 sqm (1,141 sq ft), excluding earthworks.
Considering a soil class of 6, the quoted costs including removal of soil quantities seem too low to me.
The question is also how the earthworks and basement costs are exactly divided, for example, inspection shaft, trenches, wastewater, gravel layers, foundation earthing, etc.
