Land surveying included / what to pay attention to?

The building area and your plot must somehow be surveyed before you come with a house. Where does your (Maurerpolier) surveyor want to have a reference point? The fact is that the plot should/must be surveyed in terms of appearance. Then, after the building permit, someone who knows how comes and roughly stakes out your house, etc. That way, the excavator driver or whoever knows where the house is going. The civil engineer excavates everything and the surveyor comes again: the fine measurement. Once the house is standing, the authorities write to you after x months and a publicly appointed surveyor re-measures everything. This way your house is also correctly recorded in the official catalogs, etc.

which a trained bricklayer foreman can also manage.

Since Nordlys never tires of promoting the completion of staking out by non-surveyors, I must presumably not tire of expressly warning against it. If errors occur, insurance companies regularly classify this behavior as grossly negligent and exclude any liability.

in addition to boundary surveying, only the marking out and much later the building surveying are left

The marking out of the new boundaries is, at least in NRW, legally part of the boundary surveying. At the request of the surveying office, this can be postponed under certain conditions (see , #4). A special commission is only required if the boundaries had already been marked out but the boundary markers have been lost.
