Announcement of shell construction completion for prefab house

When is the shell considered complete in a prefabricated house? In principle, the house is completely erected within a few days. I would have assumed that the shell is considered finished after that. I would have to inform the building authority of the date 2 weeks in advance, including the inspection by the chimney sweep. But the chimney is only built during the few days of the house assembly. How is this handled? We want to continue building as quickly as possible...

Why do you have to take care of this and not your general contractor - in the case of complete contracting - or your architect in the case of individual trade contracting?

As a rule, the closed shell construction is meant - masonry, carpentry + roofer.

Rhenish regards

I am taking care of it because although I have a site manager (neither BU nor architect), I am taking care of it myself. It doesn’t matter anyway, I just want to know or gain experience with it. So, a prefabricated house with a chimney is built within a week (timber frame, windows, roof covered). After that, it should continue.

Hello,

we had the same problem.
After the house was set up, we contacted the [Schorni], who measured the chimney (determined suitability), sent the certificate by mail, then forwarded everything to the building authority. A short note explaining that due to prefabrication and partial rescheduling, the 14-day deadline cannot be met. We had no problems at all; when no response came after 1 1/2 weeks (interior work only after approval), we called and were told that we are not actually as far behind schedule as planned – we can proceed. The background of this statement was that when reporting the shell completion, we also had to include the shell measurement – this was one of the conditions of the building permit. The verbal agreement was also no problem afterwards during the building inspection – but in hindsight, I would insist on something in writing.
