Fully built - now tame the chaos!

I simply don't see any risk there. Formats may become obsolete, but they will be openable. Or rather, a period of decline will last long enough that there will be enough time to recode everything.

In our possession. Building, built 1979. to be sold as there is no longer any need. Expert committee district is to prepare a market value appraisal. Plans in the archive. Invoices too, they are just junk now. interesting. But static calculations, drainage plans, tender texts, that is relevant. In addition the bricklayer plans. Good that all of that was still there. On paper. What happens with the electrician xy's invoice is not the point.

Important to me: 1.) The format must be standardized and openly documented. There are countless PDF readers on the market --> low risk. 2.) The file must "belong" to me.

We scan invoices. Many nowadays only with a document scanning app on the phone; have to scan the invoices for the [PKV] as well. These things are submitted online to the bank or insurance anyway. These documents go into yearly boxes. After 10 years, the box contents are sorted out. For the relevant documents like the notary contract, we have a folder.
