Regulations for Construction Work Standard Times

What do you want to know the times for? Do you want to create a project schedule with them?

You are approaching this way too theoretically. My electrician slipped on black ice, now he's out for 2 weeks! My neighbor forced the general contractor 4 weeks ago not to lay the screed during frost. Thus, a 4-week delay. The window fitter needed 1.5 weeks longer for the window installation because the compression tape takes 3 days in winter to fully expand. In summer, you can't install it as quickly as it expands. Even if one trade does not follow another, you have downtime.

And if you now think "yeah yeah, that's all just because of winter," it might be true for some of my examples but 1. you will catch at least one cold period and 2. in summer there are simply other possible delays.

My neighbor started in April, I started in mid-October, and the difference in construction progress with similar complexity and the same materials is maybe only just under 2 months.

So any actual and target times are nonsense. You cannot plan your construction exactly or satisfactorily over the course of time.

So any actual and target time stuff is nonsense. You cannot plan your construction exactly or satisfactorily over the course of the process.

I’m talking about theorists. Just like at work with the project managers who always make mistakes.

That’s all about it ... see photo

It is about the reference values that define a TARGET condition.

That’s what I was talking about. Same model, 1.4tfsi DSG with and 1.6tdi manual without climate control, two completely different target values. And with houses, there is no such thing as transverse or longitudinal modular design, Müllers build completely differently than Meiers. In a single corner of an attic bathroom, more dimensions converge than an Excel list can have hierarchy levels. Your project can only succeed if the desired outcome is proof that the theory is wrong ;-)

As Dr. Hix already pointed out above, such guidelines do exist. You just have to google, for example, "Arbeitszeit-Richtwerte für Wand- und Bodenbeläge im Dünnbettörtel" to find a corresponding publication from Institut für Zeitwirtschaft und Betriebsberatung Bau. It is therefore possible to consider different specific features of the work execution, e.g. tile formats, laying heights, size of the areas to be produced, etc. (of course, these are not all possible features, but the most important ones). The statement that such guidelines would be impossible is therefore not correct. The point, however, is that the guidelines mentioned above are not official. My original question was and is whether there is something like an OFFICIAL guideline. So far I can only read the answers NO. OK, thank you very much! The question of whether such a guideline makes sense and can be applied in real life is a completely different question. Yes, I need it for a very rough planning. Yes, I understand that some factors cannot be foreseen.

Well, if you have a subsubsub who gets a fixed price, he will speed up. If you have one on an hourly basis, he will take a cigarette break every half hour.
