Cost estimation for electrical installation

I told you, you have many cost drivers in there. If you were to remove them or replace them with something else, you would most likely nearly halve the costs. Even without prices behind it, you can "see" that the numbers are always getting bigger.

For example, USB sockets, recessed spotlights (I bet they are really overdoing it here), sauna, supply lines for electric car(s), and of course the intercom system.

But of course, I'm not a clairvoyant and could be wrong.

Thank you! I appreciate your experience. What bothers me is that the details are missing in the offer. Therefore, I would ask about it just to be sure. For comparison, I will get a second offer. During the construction phase, every trade is a "battle" involving time and money...

I would like to intervene here: Can't a builder assume that the data lines are always patched if this is stated in the offer as with the OP? What other sense would that make? The electrical consumption points are also properly connected and secured in the control cabinet, which is also not explicitly mentioned in the offer.

Is 45€/h appropriate for an Elli? Just asking.

Depending on the region, it can be significantly higher.

Can't a client assume that the data lines are always patched if this is listed as such in the offer, like in the case of the OP?

I think if it's not stated in the offer, it should simply be discussed and clarified. As a rule, it is included, but I have also heard or seen a few times that the installation cables just end up plain and simple in the utility room. Even if the offer states patch panel, there are still many unknowns. Does the electrician simply screw a basic patch panel to the wall or does he use one for a 10" or 19" rack? LSA or keystones? Personally, I would only use keystones in the patch panel because you can rearrange the cables in the patch panel afterwards. In a renovation, you just clip out the keystone modules and don’t have to deal with a bulky patch panel.
