ᐅ What does the electrician do during the shell construction phase?

Hello everyone,

Which tasks are absolutely necessary for the electrician during the shell construction phase?
I believe the main priority is the main electrical connection, that is clear to me.

My situation is that I am just starting the electrical planning now, but the shell construction will begin in the next few weeks (I won’t be finished that quickly).
I plan to do the chasing myself, as that allows for flexibility and can be done once the shell is up... but what SHOULD definitely be done by a professional electrician while the builder is constructing the shell?

Best regards

How was your current grounding installed? You mention, for example, incorrect clamps. So, in your opinion, what exactly does not comply with DIN or other standards?

Do you already have an electrician who will handle the registration with the electricity provider? If so, they will tell you what they need, whether any compensation measures are required, or if they will simply sign off regardless of how the work was carried out.

Doing it yourself, chasing channels, and so on doesn’t really help.
Before the electrician explains how everything should be done, and still some things go wrong, he can actually carry out the work faster and more precisely himself.
What really helps him? Keeping the workspace clean and free of clutter.
Just my practical experience.

Hello... we are also building through a developer and now we have the following problem...
The grounding was not installed or inspected according to the new regulations!

Before everything started, I was looking for an electrician myself instead of immediately accepting the developer’s electrician.
Now the grounding (installed by the structural builder) was fitted with the wrong clamps and no professional inspection was carried out. So there is no documentation available, as far as I know… (?) I’m referring to the “DIN 18014-2014-03”.

A ring earth electrode is supposed to be installed later.

The fact is… where do I get the documents from?
Am I to blame now?

From a measurement standpoint, you can still have the functionality of the grounding verified. However, you won’t be able to provide proof of proper (or improper) installation. Are there no photos at all?

Were no photos taken of the shell construction? From a measurement perspective, you might still be able to provide proof of the grounding’s functionality… but this does not protect against improper installation.
By the way, this is not an isolated case…

As far as I know, the steel straps must be connected using a "screwed clamp." In our case, they were crimped.

I can’t say if this was done in V4A stainless steel in the concrete... at least from the outside, it appears to be.

There is no documentation or photos available.

My site manager just pointed out that I should have taken care of it myself!

Theoretically, he is right if you want to choose the electrician yourself and you already knew the date for the foundation slab. In that case, you could have canceled or arranged for an electrician to be there.

However, from my experience, I can tell you that more than 95% of the installations have mistakes, and your electrical devices don’t necessarily fail because of that. Do a measurement and check if the values are within the correct range. If they are really way off, there are other options available, though they may require some effort.
