ᐅ Surveying Cost Estimation

@Escroda
Could you possibly describe the typical process in a new residential development from the perspective of a surveyor?

How current is your official site plan? What does the purchase agreement state? Do you already have a parcel number for the plot? Have you submitted a building application or even obtained a building permit?

The site plan is older and includes the two specified parcels. No, I don’t have my own parcel number yet, and I doubt I will get one before the building permit. The building application is planned to be submitted in January/February 2018. See screenshot.

I just don’t understand why the building authority is causing such delays now. They should measure the property as agreed in the contract, and that should be enough.

At the moment, I’m not clear on what surveying steps I need to take now.

To keep it simple, let’s leave out land consolidation and assume the entire area belongs to the municipality.
-The municipality plans the establishment of a development plan (building plan / zoning plan).
-The boundaries of the parcels of land that match the procedural boundary of the development plan are located onsite and precisely surveyed (creating a coordinate register for the outline).
-Designing the development plan according to the urban planners’ specifications (especially the geometric definition of street boundary lines, building setback lines, and building lines).
-Dividing the area into practical parcels (building plots, streets, green spaces, etc.) and thereby determining the exact boundary point coordinates using CAD.
-Integrating the subdivision into the official cadastral register.
-Rough staking out of boundary points and marking them with wooden stakes.
-Staking out the construction roads (for example, using nail markers).
Once most of the plots are built on:
-Marking the boundary points with permanent markers.

For each individual building plot:
-Topographic survey of the building plot (elevation, trees, utility installations, supply and drainage systems, etc.)
-Site plan for the building permit / planning permission application
-Rough staking (for basements)
-Fine staking (string lines for construction layout)
-Building measurement survey (after completion)
If boundary marking has not yet been completed:
-Boundary notification for fence construction

I’m currently unsure about the next steps for surveying.

Your plot has not yet been registered in the land registry. However, the coordinates should already be established. Your purchase contract should include a plan, which is likely held in digital form by the local authority. In Bavaria, the situation is quite different, as there are no publicly appointed surveyors, for example. I don’t know whether in your area independent surveying firms usually prepare site plans for the building permit / planning permission or carry out the staking out. Ask your designer. They should request the digital plan from the seller if a surveyor is not to be commissioned or required.

At the moment, there is the planning documentation (see screenshot) plus plans from an engineering firm (site plan showing sewage system, road, gradients, etc.) that were prepared for the local building authority.

In my view, the site plan for the building application is represented by the screenshot. Therefore, I would only need to commission the rough staking out (for the basement) and fine staking out (string lines).

Or possibly also the topographic survey of the building plot (elevation, trees, utility infrastructure, supply and drainage systems, etc.). But isn’t that already covered by the planning documentation and the site plan showing sewage system, road, gradients, etc.?

What reference points does a surveyor use when standing somewhere in a field? In my case, it would be simpler since my plot directly borders the existing developed area. But who can confirm that my eastern neighbor has respected their property boundary?

No. Your screenshot seems to be an excerpt from the zoning plan. The site plan is defined in the Building Submission Ordinance (BauVorlV) in §7. Which details your local permitting authority requires must be clarified there. Also, on which plan basis the approval can be granted, since the cadastral map has not yet been updated.

What does a surveyor base their work on when standing somewhere in a field?

On the stars. Well, not exactly. The coordinates are shown in real time using highly accurate satellite positioning on the relevant devices, similar to a GPS, but much more precise.

The responsible local office of the Bavarian surveying authority or an employee of a private surveying company.
