People work on a construction site and then mistakes always happen. The advantage here is probably the external expertise that was definitely purchased and can be on site all the time.
Regarding the first sentence: Several contractors have already told me that, and it's all true. I am still waiting for the contractor who then lists the measures he has taken to minimize the number of mistakes in the second sentence. That's the one I will build my next house with.
Regarding the second part: Well, that’s a speculation on your part, isn’t it? We don’t know if anyone was paid to be on site as a quality inspector all the time. Hence my question...
Regarding the pictures: Respect, all very nice and above all great that you share this here so unpretentiously!! I really like the style!
