Land Surveying

You can measure whatever you want yourself, it just doesn't count. If the boundaries haven't been marked, it will have to be measured again. Who pays for that then has to be clarified. The answer here is quite simple: most likely you. But just ask the surveyor again what exactly he measured.

Wooden stakes are not recognized boundary stones or boundary markers. If you have agreed to buy a marked plot of land, then you can demand proper boundary stones. If not, then not. The surveyor will not set boundary markers, but only measure for his/your site plan. For the preliminary work for a soil survey, your tape measure acrobatics are sufficient. The soil surveyor usually refers to existing fixed points or, for example, manhole covers for height and location.

Look at the cadastral map: if you are not building in the field, the property has certainly already been surveyed. Where there are circles at the corners on the map, there should also be a stone. These often disappeared into the ground because no one kept the stones clear for years. But most of the time they are still there. For our survey, all boundary stones were also found again, even though we thought there was nothing left because the farmer had been constantly plowing the field for over 50 years. So if there are circles on the map - look for stones. It is of course sensible to measure beforehand where they should approximately be.
Good luck!

I would generally advise against surveying the property yourself. For the building application, a site plan has to be prepared anyway, and the property elevations for the elevations and sections in the construction drawings have to be determined. That means that a surveyor has to survey the property anyway, and they can then also mark the property boundaries.
