Cost estimation electrical planning

Yes, I am actually a layperson in this regard. I just googled and saw that these are made of plastic and are white. That is actually the standard for me.

We can probably do the electrical work ourselves and for this
a credit for the electrical work according to the construction description, including laying the power cables for the heating circuit distributors/room controllers and the additional line from the outdoor unit to the fuse box would amount to €3890.

However, the electrical cost is now down to €10,000, which will probably be too much considering the equipment. Otherwise, there are no electricians from the developer who would want to take on this job...

The standard was 88 empty boxes for sockets and switches. Everything beyond that was subject to a surcharge.

Can you even generally say that an offer is overpriced

If that is the entire service (23 sockets, blinds switches, data sockets, a few light switches and surge protection): yes
How can the meter space even cost anything? There is only a rail and three cables, the meter itself is then provided by the network operator (possibly also installed).

really rubbish, e.g. a single socket in the kids' room?

23 sockets in the house? I don’t understand. Something is missing there

I checked again, the switches are from Reflex SI.

BJ Reflex SI is really standard. I don’t know any electrician of sense who would install cheap articles from Ebay/Amazon for €1.50 the illuminated socket, and the Reflex SI series is standard at BJ. A socket with cover costs about €5, same for the switches.

We can probably do the electrical work ourselves and would receive a credit for the electrical work according to the , including laying the power cables for the heating circuit distributors/room controllers and additional cable from the outdoor unit to the power box, amounting to €3890.

I don’t understand.
On the one hand, you have a general contractor (GU) with a construction description including the electrical work, for which you would receive a €3.9k credit if done yourself or subcontracted. Then you write something about electrical work down to €10k and no one else wants to accept the order – and in the offer you copied in, it states €23k. I’m confused.

Either you have a general contractor (GU) with a construction description that includes the electrical work. Then you can diverge from the construction description and coordinate/commission this separately with an electrician. Of course, then you are bound to the electrician of the GU. Who and how many want to take the order from the GU is not your problem; you only have to pay separately for the performance that deviates from the construction description.

Or you take the electrical work out for a corresponding credit and commission an electrician of your choice externally. Then you can make as many requests as you like without the GU electrician having any say.

If you outsource that, however, you are solely responsible for ensuring that your electrician adheres to the construction schedule and is finished as soon as the following trades want to start their work. Otherwise, it can quickly become unpleasant for you.

The 3,900 EUR credit could be about right. On the one hand, the main contractor (GU) gets prices from their regular electrician that Otto Normal wouldn’t get even in the deepest crisis of all time. And of course, the GU doesn’t waive their profit share on this trade either, just as they factor in a kind of "penalty payment."
In short, if you were to take out the electrical work and request exactly the same scope from an external electrician, it would easily be 20, 30% more expensive than the credit you received. If that suffices.

Therefore, I would more or less bite the bullet and have the electrical work done by the GU’s house and yard electrician. Tough luck, yes. But the risk is not insignificant.
The best thing that can happen to us is if the customer doesn't finish their part. On the one hand, it serves as a permanent excuse when the project is delayed ("if we had started on time... now we have capacity problems because you dawdled...") and on the other hand, it can also lead to additional charges if deadlines such as the fixed-price commitment are significantly affected.

And whatever your electrician messes up will of course be used in every possible way as the cause for all conceivable defects and problems for which the GU cannot be blamed because your electrician totally screwed up ;)

By reducing it to 10,000€, I meant we have now cut quite a few things. Outdoor area/ e-mobility provision/ separate media distributor/ smart home integration for blinds and spotlights. That amounts to just under 8,500€ net in total.

I thank you all and will probably take the electrician, whether I like it or not. I briefly considered cutting the ceiling outlets for the spotlights since the bungalow already has a wooden beam ceiling. But as it is, you want to have it all at once...

And again someone who really wastes a lot of potential through the "eat or die" tactic of the GU/BT. Too bad.

If you subcontract that, however, you are solely responsible for ensuring that your electrician adheres to the construction schedule and is finished once the following trades want to start their work. Otherwise, it can quickly become unpleasant for you.

The 3,900 EUR credit could very well be accurate. On the one hand, the general contractor (GC) gets prices from their preferred electrician that Otto Normal (the average person) wouldn't get even in the worst crisis ever. And of course, the GC does not waive their profit share on this trade, just as they factor in a kind of "penalty payment."
In short, if you were to take out the electrical work and request the exact same scope from an external electrician, it would easily be 20 or 30% more expensive than the credit you received. If that’s sufficient.

Therefore, I would bite the bullet more or less and have the electrical work done by the GC's in-house electrician. Unfortunate, yes. But the risk is not insignificant.
The best thing that can happen to us is if the client doesn’t finish their part. On the one hand, that serves as a permanent excuse when the project is delayed ("if we had started on time... now we have capacity problems because you dawdled...") and on the other hand, this can also lead to additional claims if deadlines like the fixed price guarantee are significantly affected.

And whatever your electrician messes up, of course, will be used as a cause for all conceivable defects and problems for which the GC can’t be blamed, because your electrician really screwed up ;)

And that is exactly how it is after consultation. Additionally, the electrician would like a compensation payment of 500€ for planning purposes.

Theoretically, the electrical work is the last trade for us. Filling and painting will be done by ourselves. So we can actually mess up as much as we want, the roof and walls are already in place.

I think the methodology is similarly structured at many construction companies.
