TV show about the tricks in construction...

For that, then experts.

Yes, but the willingness to take that on is very low ... what does the site manager do if he ruins the relationship with the trade at the construction site these days at the next house he wants to build?

Better an architect who doesn’t care at all who he works with

We’ve even talked about that.

The trades are also scared that the situation might reverse. There were other, better times, and there will be other times again. Then the trades will be begging the architects for contracts.
They are also afraid to build up personnel during the ongoing boom and not be able to get rid of them again when the orders dry up.

Our expert had determined that actually a bitumen layer belongs under the perimeter insulation and that the boards should not be dowelled into the concrete at the basement but rather glued on ....

The site manager always works with this structural builder, do you really think the expert will help you now? He only points it out .... you have to handle the confrontation with the site manager and structural builder yourself, and the site manager won’t upset the one he depends on ....

I clearly advise against creating such constellations in today’s times ....

The structural builder didn’t feel like tearing everything down again and we didn’t feel like going to court .... and even if you go there every day and look ...
They put up something like that in 4 hours, you can’t watch that fast

At the next construction, I’ll take the whole time off during structural work, roof, and plumbing

Our expert had determined that actually a bitumen layer belongs under the perimeter insulation and that you shouldn’t bolt the panels into the concrete at the basement but rather glue them on....

The site manager always works together with this shell builder, do you really think the expert will help you now? He only points it out... the confrontation with the site manager and shell builder you have to handle yourself and the site manager won’t upset the one he depends on...

I definitely advise against creating such constellations in today’s times....

The shell builder didn’t feel like tearing everything down again and we didn’t feel like a legal dispute.... and even if you go there every day and check...
They built something like that there in 4 hours, you can’t even look that fast

Next time I’ll take time off completely during the shell construction, roof and plumbing

Yes, this is how it’s done according to the manufacturer’s instructions.
Did your expert also tell you why it’s done that way or why the manufacturer recommends it? I’m curious about the answer, because I can also quote manufacturer specifications :)

Yes, he did, on the one hand to ensure that absolutely no water gets through, and on the other hand, you shouldn't drill into the concrete because that weakens it, even if only minimally. Additionally, they are then simply nice and flush, which pleases the plasterer.

Ok, for an open basement that is still going to be plastered, I can understand that. For an in-situ concrete basement where the soil presses against the perimeter insulation, your method is common practice and, according to my offer, saves about 3k gross. Even without glued insulation, no water comes through :) Now the question is, did you pay the 3k€ and it was not implemented, or was it “credited” to you because it was not executed.
