In my opinion, you forgot the point that, from my perspective, competent and reliable people usually rely on others to also do their job competently and reliably.
One would think so. But what I have experienced in the 12 months since we started building, no one believes me except my neighbors who have witnessed some of it and were even partially able to see it.
My husband and/or I were also regularly on the construction site, but "actually" only to replenish drinks, food, etc..
We did that at the beginning too, but after certain incidents (trash stuffed into the hollow bricks, half sandwiches thrown into the light well, etc.) we stopped. We still regularly serve coffee.
We were always available as contact persons for all topics, but avoided giving the impression that we were controlling anything.
Most decisions are made on site at the construction site. Of course we didn’t do inspection rounds while the craftsmen were there, unless something major caught our attention. But we addressed deviations from the standard without bias. For example, they started installing non-airtight boxes in the external walls – but since the 2014 Energy Saving Ordinance this is mandatory. Empty conduits from the cold roof and through the building envelope were not sealed, ventilation ducts sloped away from the house instead of towards it (condensate drainage direction), and many, many other such details that ultimately influence the quality, comfort, and efficiency of the house.
However, this was the first time in our lives dealing with craftsmen, maybe it’s different in that trade.
I grew up in a family with a craft business ;-)
And yes, of course it is an advantage to live close to the construction site, but if that is not the case, you have to get someone on board for that. I repeat myself when I say that this is the biggest and probably most important investment in life, and I have no understanding for recklessness along the lines of: "It will be fine, they know what they are doing." WilderSueden put it very aptly: whoever cannot or does not want to take over construction supervision (outsourced), may be better off buying an existing house. I absolutely agree with that.
