Floor plan planning shortly before submitting the building application

The expert was here for three hours today. Unfortunately, I am very stressed right now and will only write what burdens me the most.

The patio doors have a passage height of only 184 cm. In the execution plan, the windows are listed as 101x201. There is now a dispute about this. The expert says that one must assume a passage height of 201 cm and not that there is a thick substructure that reduces the whole thing to a passage height of 184 cm. Furthermore, there is a DIN standard that prescribes a minimum passage height for patio doors of 2 meters.

The general contractor says that everything is completely correct according to the workshop planning and the contract.

Now I am waiting again for a few days for the expert report, while all the windows are already being installed today.....

Even if it should turn out to be lawful, the question is whose mindset the planning architect had when he planned a passage of 184 cm for a 189 cm tall man. That is completely crazy.

Regardless of that, I told the expert that it is a shame that during the review of the contract and the related floor plans he did not notice that we should have planned directly 212 or the next higher DIN standard.

Very bad.

If I remember correctly, you also have a ceiling height higher than 2.50m (standard), which is why I (and previously others) had already recommended that you choose higher passage heights to visually harmonize everything.

Now it seems to have unintentionally gone in the other direction. :O
If I understand correctly, you now have a lintel of at least 75cm above the doors?
I do wonder where the hell there was even one person involved in the construction with a bit of sense?!?
That (!!!) has to be noticeable as soon as you stand in the shell construction for the first time...

Is it the same with the windows?

In our workshop planning, all the parapet dimensions and also the top edges of the doors were specified from the raw floor. For the terrace doors, this was a height of 2.565m. With a floor build-up of 16.5 cm, this resulted in a finished height of 2.40m for us.
Anything other than such a specification would not make sense and would only lead to confusion and errors since the shell builder needs the measurements and only has the raw floor as a reference.

Even if my post here doesn't help you much, good luck with the matter. I would be very interested to know how this will be resolved, after all, the shell construction is already standing, if I remember correctly...

Oh dear, I'm really sorry. No one can use such annoyance. In my opinion, that is a lazy excuse from the [GU]. I'm not sure if the [GU] is simply allowed to deviate from the [DIN]. If a deviation from the [DIN] is possible, he must inform you about it and you would probably have to sign exactly for that. Maybe the [GU] just wanted to make you say on the construction site, yes, then that is my fault, sorry, continue. Wait for the report. Otherwise, you have to threaten further legal steps.

If I remember correctly, you also have a ceiling height higher than 2.50m (standard), which is why I (and previously others) already recommended that you choose higher passage heights to visually harmonize the whole thing.

I think the discussion was about the interior doors. They are now specified with 2.13m in the execution plan because that advice seemed very plausible to me. God knows why we didn’t think of that with the terrace doors and why the expert didn’t notice it either, who also made many corrections for the working drawings.

Annoying. We'll have to see now.....

Is it the same with the windows?

It is probably the case that the same standards were applied everywhere. But we didn’t look at every window. We were actually just installing the windows.....

In my opinion, that’s a lazy excuse from the general contractor.
I’m not sure if the general contractor is allowed to deviate from the DIN standard.
If a deviation from the DIN is possible, he has to inform you and you would probably have to sign off on it specifically.

I’m first of all looking for the relevant standard.

I don’t know what went wrong there – possibly in connection with the reduction of the floor heights shortly before approval. In any case, nothing caught my attention because in the section drawings the heights of the openings are not dimensioned.

The opening dimensions are usually given as shell construction dimensions. Unfortunately, this is a relatively common source of error with today’s thick floor constructions, since door openings are, of course, also constructed “open at the bottom” in the shell construction – that is, a “parapet” is not built up to finished floor height, but the floor construction is covered on the outside with a panel.

"1.7.5. The floor-to-ceiling window element on the ground floor size 3510*2260mm is executed as a lift-and-slide element." from the contract text indicates that this is meant as the clear opening dimension after the floor construction; concerning the upper terrace doors, I did not at least find the specification quickly.

I mean, the discussion was about the interior doors.

Unfortunately not.

Since it somehow doesn’t show me older attachments anymore:

What finished room height do you have?

I’m asking because of the window size.
You write that the parapet height is no longer correct, it is now 90cm.
I assume YOU mean measured from the finished floor.
In our plans, however, the parapet height was given in relation to the raw floor, since this measurement is important for the rough builder who initially doesn’t care how high the floor build-up is. I understand that your plans are still drafts and not execution plans, but still a dangerous game.

Also, I think I read somewhere that you are planning higher room heights than 2.50m, which makes sense for a house of this size. Since I don’t know how high, I’ll assume 2.75.
BUT:
Are you aware that although you increased the room height, you did NOT do the same for the windows and doors?!?

According to your office picture, there is a lintel of ~49cm(!!!) height above the window. 2.75m - 1.00m parapet - 1.26m window height = 0.49m.
In the end, this looks as if you set the windows too low. The same applies for the interior doors.

Apart from the fact that I don’t even like the obligatory 30cm lintels myself, that would be a real no-go for me...
