Let me say that so far and without knowing yet how the results will look
like in total this seems to be a quite positive example of preparation
of an import project. I am particularly referring to
- taking sufficient time to plan things, give people opportunity to
review and give feedback.
- actually take feedback into consideration and change plans based on
it.
- not taking too much on in a single step (here: leaving out the
addresses for example).
Looking at the data entered so far at a few places it seems there are
quite a few obvious formal errors like geometry artefacts:

and misclassification of industrial infrastructure as buildings:

It might be a good idea to refine the data preparation for future work
packages with special regard to these kinds of problems (like detecting
very narrow geometries and industrial buildings with non-rectangular
geometry and marking them for manual inspection).
