Hello,
we now have the following "conflict" to resolve.
We are building a 14 x 14.5 m (46 x 48 ft) bungalow. The soil report indicates the following layers:
Layer 1: Topsoil 20 cm (8 inches)
Layer 2: Sand, highly silty, soft to stiff, gray-brown
Layer 3: Sand, highly silty, humus, soft to stiff, dark brown to black-brown
Layer 4: Sand, low silt content, partly silty, medium dense, ...
Recommendation: remove 1 to 1.1 m (3.3 to 3.6 ft) and refill with compacted gravel or a similar material.
Now, a groundworks contractor who has seen our plans pointed out that he was not informed about our planned fill. We actually need to build up an average of 1 m (3.3 ft).
He suggested that it would be sufficient to just strip off the topsoil (and possibly some centimeters of layer 2) to achieve a 1.4 m (4.6 ft) gravel layer underneath the foundation slab. If necessary, the foundation slab could be made a bit thicker and the reinforcement adjusted accordingly. This would save us money.
However, our structural engineer insists that everything must be removed as recommended in the soil report.
Now we are uncertain. Both are professionals.
We will consult other groundworks contractors to see their opinions.
However, this involves a significant amount of money. Has anyone here had experience with a similar case?

Definitely not. 🙄
But let's drop the discussion, you always seem to have experiences that contradict your own opinions anyway. says the one who in turn contradicts my experience. Are you even noticing that yourself?
So you are saying that there is NO safety factor included in the hole, and the engineer simply approves it like that! The engineer has absolutely no problem with even the slightest deviations from the assumed value (e.g., 20cm (8 inches) next to the drilled hole is 20cm (8 inches) deeper due to scraped off, poorer soil) leading to cracks in the house and being sued for hundreds of thousands.
Do you also believe in Santa Claus?
And don’t come at me now saying you didn’t write that. THAT is exactly what you wrote, since you called my safety concerns nonsense!

sagt der, der meine erfahrung widerrum einen entgegensetzt. merkst selbst oder? My statement is different from yours in that it is not a generalization but based on my experience. You say that no one would ever sign it. I say that is incorrect because it was done in my case. Do you see the difference?
Payday schrieb:
du sagst also, das KEINE sicherheit beim loch mit drin ist und der mess ing das einfach mal so unterschreibt! Please don’t twist my words: I wrote "definitely not" in response to your statement "definitely too big and deep 🙂 (so serious safety included)." So I did not say there was no safety at all.

du glaubst auch an den weihnachtsmann oder? And you only see black and white.

und komm mir nun nicht dabei das du das nicht geschrieben hast. GENAU das hast du geschrieben, weil du ja meine sicherheit als quatsch bezeichnest! What safety did I call nonsense? I only said that there are people willing to put their statements in writing and thus take responsibility for them. You, on the other hand, say this never happens, and I shared my experience to the contrary instead of generalizing. So calm down...
Hello,
I wanted to share how things turned out.
We have since talked to several people. A friend who has built several houses was especially helpful. He pointed out that in the event of a legal dispute, the soil report will serve as the basis. Everything else is then irrelevant. Based on this, we have now found a groundworks contractor who seems trustworthy to us and obtained our quote (as a worst-case scenario) based on the report.
Thanks to everyone for the exchange of ideas.
