Construction road over existing house lines?

Dear all,

we are concretely planning the construction of a semi-detached house and recently finally had our construction kick-off meeting with our site manager at the construction site. The entire building plot is quite narrow and long towards the back and consists of three individual plots. Our semi-detached house is to be built at the front and a single house will be built at the back with corresponding access via the two front plots (one of which is ours). After inspecting the conditions, the site manager concluded that the 3 meters between our house and the property boundary is not sufficient for heavy and wide construction vehicles to pass through to the back to the construction site of the single house. Therefore, the house at the back should now be built up to the screed stage before anything can start on our side; there was talk of a waiting time of 4-6 months depending on weather in winter! That shocked us, of course.

Now we see an alternative to build a construction road on the other side using the neighboring plot. Their access road to the house at the back already runs there (the neighboring plot basically has the same layout: one house at the front and one at the back). So, we would use part of the neighbor’s path for the construction vehicles to go to the back. The neighbor is basically open to it but had an expert with him who pointed out that existing gas, water, electrical, etc. lines run under the existing path and it must be checked whether heavy construction equipment can actually drive over it. He wants to clarify this with the utility company. If the utility company does not explicitly confirm that crossing is possible, he will probably not cooperate.

Now I wanted to ask around if any of you have encountered the situation that the construction road runs over an existing path, possibly over the neighbor’s property? Does anyone know DIN standards or guidelines regarding which loads can be driven over such a path with lines underneath? I would have thought that it is not so uncommon that one can only access a construction site via an existing path, especially in metropolitan areas.

Thank you very much!

if the cables were not built to be driven over, I would not let anyone drive over them, you will pay for the damage. It can become very expensive if all the cables need to be reinstalled. We had the cables in before, but exactly in the middle, at 1.5m, not under the driving lanes. Wait your time, and agree with the site manager

I simply cannot imagine that anything will happen there. No 100-ton excavator is going to drive up there. I work at the energy provider and it doesn't matter where the line is located for us. Nowadays, there is often development in the second row and the lines frequently run through the driveway "in front" as well.

Thank you for your answers. Let's see, I find it hard to imagine that anyone from the municipal utilities would give the green light for the passage if it is not clearly defined somewhere. If something happens, he would essentially be liable. That is why I am concerned that they would rather dismiss it outright...

On our side, there is 4.67m of space between the house wall and the neighboring property. Even if the house were scaffolded, that would not be enough for the trucks to pass?

No, it’s too narrow. You can roughly estimate the scaffold at 1.5m. Even with the 4.67m, it will be difficult to, for example, get a crane through. That such a thing isn’t already clear from the records, however, is surprising.

At the beginning, the scaffold is on the masonry, then outside the roof overhang, so it is too tight. Construction roads grow in width exactly to the maximum possible.
