Development costs for a plot in the second row

We are currently having an offer prepared for 50m of path including wastewater, surface water, and a complete heavy-duty construction as a construction road and then a fine layer, so that it becomes a clean road to the house. Path: spoke with 2-3 construction companies. One was interested and came for the measurement (channel depths, cover heights, slopes, surfaces, etc.) - Without measurement and exact estimation of depths (channel construction in open trench or with shoring in the shaft, etc.) no one will be able to give you a reliable figure.

Without measurement and precise estimation of the depths (sewer construction in an open trench or with shoring in the shaft, etc.) no one will be able to give you a reliable number.

You are absolutely right. I have already spoken to a sewer builder. We are meeting next week. He wants to submit an offer by the end of the week. I’m curious to see what comes out of it.

Have you already received the offers? If yes, how much do 50m cost for you? In which federal state and city are you, if I may ask.

There is no development plan. We have to follow $34 of the Building Code for the modifications. Requests to the city have already been made and preliminarily approved.

I am glad to hear that - especially if this also applies to the building envelopes (that there are no "de facto" objections that would say no here).

Have you received the offers yet? If yes, how much do 50m cost for you? In which federal state and city are you, if I may ask.

No, I am still expecting the offer.
Franconian Switzerland. It should probably mean something to you.

the costs depend heavily on the local conditions,
passage 3m, also in height, rain gutters front house,
support/protection front house,
space for excavation storage, construction clearance around the house.
We also have 70m 2nd row, Berlin.
Gas deselected, too expensive, air heat pump,
have several inspection openings laid for wastewater (spools only have 20m) keep slope very precise

40 kEUR would be finished up to the street, including crossing, ok
