Which structural shell company to choose?

How do you come to the conclusion of construction defects? Of course, I don't intend to replace a bricklayer or skilled worker, but to save on a helper. A few years ago in Baden-Württemberg, many people helped their bricklayers at their houses by carrying stones, shoveling sand, cleaning up the construction site in the evening so that the bricklayers could work 30-60 minutes longer, etc., and that only really makes sense if you are working on a time-and-material basis. With a fixed price, you don't need extra hands in the evening carrying stones.

I also don't want to waterproof a cellar or take on any other tricky tasks where construction defects could occur later.

My qualifications are good physical fitness and not having two left hands. But one should be able to do helper work, right? And as I said, if you can save a helper for the entire construction according to my calculations, that's quite a bit of money? I am very surprised that this is so uncommon?

Because on the one hand it requires much more effort than you think, and on the other hand the construction companies have little interest in it.

Watch processing videos from stone manufacturers, there you can update your ideas about construction processes. Today, many things work very differently than in grandpa's stories.

Then you might as well forget it. LOL Thanks to your help, the pros work much more relaxed (and comfortably). Five more professional hours and your helper's salary is used up and your free time ruined.

Thank you for finally saying that. Your examples are unfortunately complete nonsense. Bricks are lifted onto lifting platforms on pallets by crane, nothing is carried anymore. Sweeping with a broom is also a thing of the distant past. Debris is collected at the end with an excavator or not at all. On a shell construction, if you can’t do anything, all you can do is get in the way. Two men on my site put up the shell including a waterproofed basement from mid-October to the end of December. So why would you need a helper? To make coffee? Do what you do best, which is earning money or helping your wife. And please take a flat rate and not an hourly basis. Several people have already crashed because of that here. It may all sound bad to you right now, but these are really valuable pieces of advice.

I can't really say much about it, but I can only contribute the experience from our current construction. Within two weeks, three men built the entire house. Stone by stone. In the meantime, at our request, they fenced off the entire construction site with a construction fence, which for some reason had not been there before. They were such a well-coordinated team; they worked hand in hand silently without much talking. Admittedly, at the end of a day, there was no such thing as a swept construction site. About halfway through, the construction site looked like a pigsty. Because our architect didn't like that, they were ordered to clean up. So they also managed to do that "on the side" within those two weeks. I would think that if I had wanted to interfere somehow, the three of them would have spent more time telling me what to do than just doing it themselves faster.
