Retaining wall for the retaining wall!? Do you have any ideas?

Why do you think it will be more expensive later? That's all quite far from the house, isn't it?

Because the excavation contractor can now drive "through" your house with heavy equipment and has space to work. Once the house is built, he can only work with small equipment, has no area to store things, and has to carry everything around the house.

Oh man, I need to make an appointment with the [Tiefbauer] right away...

THANK YOU ALL!!!!

I can’t tell how far it is from the house, I can only report from our experience. We wanted it to be done first, the contractor did not. He saw no problem in anything. We also had no plans for the structure to be secured and only did a test excavation. When the time came, there were quite a few surprises, it became more complicated than expected and more extensive than initially assumed. Precisely because work was already underway nearby, which had to be stopped immediately, it was overall more difficult than if there had been a completely free area to work on. The excavations have to be secured, there must be no vibrations during that time. That definitely took 3-4 weeks until the matter was resolved.

How are we supposed to know how far away it is? Because then probably only mini excavators and small equipment can be used and the house must also be protected. Then you have a separate crew that can only work a few hours at a time. Initially, this goes in parallel with the excavation, foundation, basement, etc. First of all, the neighbor will immediately stop the construction site as soon as you mess with the SM. If I follow the photo, the house is only a few decimeters away from the SW. I would first have a documentation of the neighboring houses done. Otherwise, you’ll pay later for every small crack that may have already been there before.

That’s how it was done with us after consultation between the civil engineer and the structural engineer. Unfortunately, I have no photos where you can clearly see it. But if you search for "underpinning," you will find it; I quickly attached a photo from the internet, which shows the principle. As describes, the wall to be secured is divided into individual sections. The first and third sections are dug up, leaving the middle one standing. Then the first and third sections are concreted up (or built up with masonry, depending) up to the existing wall. When that has hardened, they move on to the section that was left standing, then dig there, and so on.

Exactly the same except that in our case sections 2 and 3 remained standing and only the 4th was dug up again. And yes, it was not cheap.
