House connection: Telekom does not want to drill through the white tank

In this case, it is really not Telekom's fault; they never do it themselves. It was stated in our documents from the beginning that the builder provides everything themselves and they only pull the cable.

Your general contractor along with the architect messed up. The house entry must be prepared with a sealed KG pipe before pouring the basement. Look!

The holes from left to right: Multi-utility, exhaust controlled residential ventilation, wastewater, air-water heat pump, controlled residential ventilation supply air geothermal heat exchanger (green)

With which plums are you having your house built?
Such a core drilling is really expensive!

It's not Telekom's fault.

That's not true, with us it wasn't done right at the slab either, but differently. Only one builder in our construction area had it done right away as you suggest.

With us, the multi-utility connection is done by the network company that installs the electricity. Through them, the civil engineer was commissioned who dug outside and then installed the multi-utility connection including an empty conduit for Telekom inside the white tank.

This time, it's not Telekom's fault.

That is not correct, with us it was also not done right at the foundation slab but differently. Only one single builder in our construction area had it done immediately as you suggest.

With us, the multi-utility connection is done by the network company that installs the electricity. They commissioned the excavation contractor who dug outside and then laid the multi-utility connection including the empty conduit for Telekom into the white tank.

This time Telekom is not to blame, exceptionally.

Interesting. Maybe we are talking past each other. With us, either the shell builder or the network company could lay the multi-utility connection.

But no hole, no laying the multi-utility connection. Now you can decide for yourself which is the cheaper option for the builder.

Before the first trenches are excavated, there is an execution drawing. For example, it precisely describes and dimensions where the empty conduits for the house connections should be placed in the foundation slab. In the basement, that’s in the wall or depending on the situation. You don’t plan where gas, water, and electricity should go during construction, but beforehand. I trained for 4 years in gas and water at the municipal utilities back then. In those 4 years, we maybe did one core drilling in new construction. Otherwise, the hole/empty conduit was always already there. Since the empty conduit was poured in from the outside anyway, it only needs to be sealed on the inside. Because the inside is pretty smooth and without holes, basically you only need to push enough "stuff" in there and the thing is inevitably tight. In those 4 years, there was only 1 time trouble with the tightness because we had changed the 2-component material shortly before and the new one was no good. It was then properly sealed again with the old stuff (Hilti HIT) and never heard of it again.

The suggestion with "going in from above" sounds good. Nothing else will work anymore.

What does the municipality have to do with it?

Whether it is now the municipality or a higher authority: something actually has changed regarding the penetrations for house connections. While we still had simple KG pipes in the slab, a former colleague already had to somehow install a rather expensive bracket there. Fire resistance or similar nonsense because of gas (we also have gas). Never heard of it being mandatory for them and probably also relatively new and mandatory. Total nonsense but probably the inventor of this bracket is the brother of the person responsible at the authority.

Correct but additionally do something better, namely use a multi-division introduction, no one can say anything against that. Neither the community nor the office.

How does electricity and such things get into the house? Our network operator has required a multi-utility house entry. These are available for walls, for the floor, and are also suitable for WU basements. Telekom is not to blame. Rather the construction manager.
