Crane and narrow access. The developer has no concrete information.

Hello, I have been planning to build a single-family house for some time now. I am now almost at the contract signing stage, but a few questions are still on my mind.

Specifically, it concerns the crane. I am afraid that the access road might be too narrow, meaning it might not be able to turn from the main street around the corner. Additionally, the path then goes steeply uphill.

I have attached a picture to illustrate the whole thing.

Unfortunately, I have not yet received any concrete information about the crane from any developer. They always just say: "That will work." I also think there is a solution, but it will certainly be associated with significant additional costs.

So now my questions for you:

Is the access road suitable for a conventional construction crane? If not, what options do I have and what costs are associated with them?

I hope you can help me. Thank you!

Developer? Whose property is it? The developer's? Then let that worry be their worry. It's not your problem.

And even if it should be a general contractor/subcontractor, let that be the concern of the shell builder if you agree with them that they shall lay x sqm of bricks and pour concrete... how the shell builder does it is their concern. Nowadays, there are also other ways to build a house. For example, we didn't have a crane (in the sense of a construction crane) on the construction site at all. We only had a bricklaying crane because the bricks were somewhat larger.

Plenty of space when I compare it to our narrow (Bau) streets in the construction area...

There is enough space. Moreover, the construction crane seems to be a southern German habit. There, at every single-family house construction site, such a thing stands around. Here in Berlin, never at single-family houses. The concrete is pumped to the right place from the mixer by a concrete pump, the pallets of stones are placed directly on the foundation slab or ceiling by the truck-mounted crane. The wood for the roof is also lifted directly from the truck to the roof. All other materials are also handled by truck-mounted crane. The few thousand euros for the construction crane can actually be saved, but if it is common in your area and all the craftsmen are accustomed to it, you probably won't get around it.
