What does the surveyor need?

Hello,

we have an appointment soon with the surveyor who is supposed to determine the necessary values for the house construction.

What does the surveyor need to start the work? I heard he needs an extract from the land register, but this will probably not be with us at the appointment. Since this can take up to 4 weeks.
Or is the purchase contract for the plot sufficient?

Thank you very much for your answers.

Hello,

District, section and parcel number - this way he knows which property to survey and can create the preliminary site plan.

Kind regards
