Construction progress: Duplex with WU basement and developed attic

The scaffolding is now also closed off. For general amusement, these signs are hanging there now. How embarrassing.

I sincerely hope that the offers and correspondence, based on which a contractual relationship with you was established, were worded differently. Otherwise, you would really have to be assigned a significant share of the blame.

What are heating loops under the tub supposed to achieve? How is heat supposed to get through there? On the contrary, according to the expert, the weight of the tub could even crush the heating pipes. Besides, an electric heater is also planned. What do unnecessary heating loops have to do with building cheaply?

I assume that the heating loops were installed in the screed and the tub stands on the screed. In that case, installing heating loops there is correct and provides more heated surface, the heating engineer is right about that. Pipes installed in the screed cannot be crushed, the entire screed would have to be damaged beforehand.

Is the note on the scaffold written by you? I hope not....

Probably not...

Then installing heating loops there is correct and opens up more heated area; the heating engineer is right.

Correct. However, it must also be said correctly that a tub on screed in new construction is complete nonsense (although technically not "wrong"). The load of a full tub + user must always be acoustically decoupled and carried via the raw ceiling. As a rule, neither insulation nor screed is designed for such loads; in this area the screed sinks and all joints crack.

What do unnecessary heating loops have to do with building cheaply, please?

What does the execution plan say about screed, areas to be left open, and slopes in the shower area? Often with "cheap craftsmen," the fee is only enough for a blunt craft implementation of the - however described and recorded in an execution plan - services. Often there is no time/money for thinking, or simply no experience.
