Dear all,

We are currently planning to build a semi-detached house and recently had our initial construction meeting with the site manager at the building site. The overall plot is quite narrow and stretches far back, consisting of three individual lots. Our semi-detached house will be built at the front, and a detached house will be built at the rear with access provided via the two front lots (one of which is ours). After assessing the situation, the site manager concluded that the 3 meters (10 feet) between our house and the property boundary are not sufficient for the heavy and wide construction vehicles to pass through to the rear site of the detached house. Therefore, the rear house would have to be built up to the screed installation stage before work on our house could even begin. He mentioned a waiting time of 4 to 6 months depending on winter weather conditions. This, of course, came as a shock to us.

Now we see an alternative to establish a construction road on the other side by using the neighboring property. There is already an access route there to the rear house (the neighboring plot is arranged similarly with one house in front and one behind). This way, we could use part of the neighbor’s driveway to get construction vehicles to the rear. The neighbor is basically open to the idea but had an expert with him who pointed out that gas, water, electricity, and other utility lines run underneath the existing path and that it needs to be checked whether heavy construction equipment can drive over it. The neighbor wants to clarify this with the local utility companies. If the utility companies do not explicitly confirm that crossing is possible, he probably won’t agree.

So, I wanted to ask if anyone here has experienced a similar situation where the construction road runs over an existing path, possibly crossing a neighboring property? Does anyone know of any DIN standards or other guidelines that specify what loads can be driven over a path with utility lines beneath it? I had assumed that it is not uncommon to have access to a building site only via an existing path, especially in densely built-up areas.

Many thanks!

If the pipes were not designed to be driven over, I wouldn’t allow vehicles to pass over them—you would be responsible for any damage. It can become very expensive if all the pipes need to be replaced.

We had the pipes installed beforehand, but exactly in the middle, at 1.5 meters (5 feet), and not under the driving lanes.

Be patient and agree with the site manager.

I honestly can’t imagine anything happening there. They’re not going to bring a 100-ton excavator onto that site. I work for an energy provider, and for us, it doesn’t matter where the cable is located. Nowadays, there are often buildings in the second row, and the cables frequently run through the driveway at the front as well.

Thank you for your responses. Let's see, I find it hard to imagine that the municipal utilities would give the green light for driving through if it is not clearly defined somewhere. In case something happens, they would be somewhat liable. That’s why I’m concerned they might generally decline...

On our side, there is 4.67m (15.3 ft) of space between the house wall and the neighboring property. Even if the house were scaffolded, would that still not be enough for the trucks to pass by?

The northeast side is too narrow. You can roughly estimate scaffolding at 1.5m (5 feet). It’s already difficult to get, for example, a crane through with 4.67m (15 feet 4 inches).

It is surprising that this isn’t already clear from the paperwork.

At the beginning, the scaffolding is against the masonry, then outside the roof overhang, so it is too tight.
Construction access roads expand in width exactly to the maximum possible.
