Kfw40, funding program 300 "low-income earners"

Construction power for 3-5k€? Where do you live and what does electricity cost there? We currently pay 33.4 cents per kWh for construction power. Aside from the heating program, there shouldn’t be much electricity consumption. Dryers and heaters aren’t necessarily needed... Otherwise, many of the craftsmen’s tools run on batteries.

The battery-powered tools also need to be charged, though they are probably rather small stuff. But things that really consume power are things like cranes, plaster silos, and machines, screed silos (with instant water heaters). In winter, craftsmen also like to run a fan heater. If the thing has a high-voltage plug, you know what’s up. Screed drying requires a lot and usually comes shortly after the base plaster inside. So there’s a lot of moisture. You can manage without construction dryers if you live next to the construction site and ventilate five times a day. And then, toward the end of the screed drying, the plasterers came and started taping everything off for the final plaster and painting. By then, the construction dryer was actually already out but had to be put back in.
All the high-voltage stuff can’t be handled with an extension cord to the neighbor anymore. Even if the neighbor has high-voltage power in the garage, it is certainly not sufficiently fused.

Otherwise, many of the craftsmen's devices run on batteries.

That almost has something of Habeck about it.

The devices don't need electricity, they work with batteries!

Thank you very much for the little satirical contribution.

There is no high voltage... for the hundredth time...

In the end, we had just under 500 kWh on the construction power meter. In this respect, 3-5,000 EUR for construction power is far from reality. That would be 9-15,000 kWh.
Absolute nonsense.

And after the screed, nearly 6000 kWh ran through with us. I don't know the rest, that was at the expense of the GU. The world can be that different.

PS: I don't care what according to DIN is Schlagmichtot high voltage or not. Colloquially, it exists.

I will not continue writing here for reasons.

That was to be expected since #1. It's a pity that you already signed and didn't start this discussion earlier. If it were my project, I would continue seeking advice here, because it is free, honest, and full of experience. Even if it is tough at first to swallow some truths, in the end you can only win. Unfortunately, I also see one or the other financial gap and probably a few surprises coming your way. My recommendation: negotiate with the general contractor that individual items can still be removed from the contract if it becomes foreseeable that the budget will not suffice. By the way, that is no shame or planning error. Something unexpected almost always happens, and then 20K can quickly be missing. We also simply organized the tiles as a self-performed task and had the item removed from the general contractor’s contract because the money was gone.

Just as an example for us:
Water connection all inclusive 1300€ for 5m
Electricity connection all inclusive 1500€ for 15m
Wastewater connection free, own civil engineer up to shaft 2100€ incl. 25m DN110/160
Telekom all inclusive 899€ for 15m

Surprisingly added for us:
Soundproof windows +5k€
Radon sealing +5k€
More excavation/removal 20k€ instead of 10k€ according to the offer

Otherwise, many here are much too strict in my opinion. There are also home builders who do not have high demands.

Have you ever totaled your expenses... but how can soundproof windows be a surprise?

But here again apples and oranges are compared, a prefab house with dry screed, in summer probably 500kWh is enough.

A more exact 250m2 house with screed and heat pump and heating rod is rather 5000kWh. Then also in winter when the construction workers are freezing and you already have 10000kWh.



Everyone who contributes here is basically right, just take all of this as hints.
