Information Frequently asked questions

Especially for private individuals, it is often difficult to make the right decision in cadastral issues (interests concerning your property).

In-depth review of our posts a preliminary understanding of any planning or surveying service is offered. Thus, contributs to a beneficial and constructive consultation with your civil engineer.

The history of today's cadastre begins in 1817, when the measurement of the Austro-Hungarian Empire was decreed by law, to provide the stipulation of property tax on an equitable basis.

The cadastre is next to the Land Registry, the second pillar of the Austrian system of property land securing. In the digital cadastral map (DKM), whose creation began in 1989, existing plans of the very first cadastre, the new cadastre and the previously valid cadastral map are incorporated. The DKM is only illustrative of the mutual position of the ground areas. The land register lists owners, rights and easements.

Only about 14% of all Austrian plots whose boundaries are defined by the formal requirements of the Survey Act 1968, enjoy the same legitimate expectations as the Land Registry. In all other cases the cadastral map gives no evidence about the actual border situation and the area extent.

The actuality of the cadastral map basically depends on the affected landowners and the relevant planning authorities.

According to § 44 VermG (surveying Law) owners and authorities are obliged to provide changes to property boundaries directly to official survey offices.

Single Plot

If you buy a whole plot (single plot), you do not need to survey the property you are going to purchase - even not for the registration in the Land Registry. The name of the cadastral municipality, the plot number and an EZ number are basically sufficient.

Subdivided Plot

If you wish to buy or sell only a part of plot, you definitely need our help. Those sudbdivisions can only be done by state-authorized and certificated civil engineers. (§1 property subdivision law)

Nevertheless, it is always beneficial for you to get in contact with a state-authorized, certificated civil engineer (IKV). With his help you have a proof that

your boundary points are at the correct position
the area of your plot in nature is as big as its size in the offical land registry or in your purchase contract.

It is definitely recommended to contact an IKV, when you buy or sell a plot in the rural area (maybe the property boundaries have not been determined so far) or if you plan to buy or sell some land where the squaremeter price is pretty high.

The construction of a house is a big financial and time-consuming challgenge in life for the majority of private individuals.

The practical experience show that painstaking delays can be avoided by a good, careful planning and the involvement of professionals.

Latest cadastral status of the plot
Current-state-plan & optimal plot-usage
Building regulations
Stakeout & height controls
Current-state-plan for dokumentation

Without latest cadastre status - nothing will work

A basic requirement for the project is a suitable plot of land. Therefore, it is important to get confirmed by a preliminary inquiry at the competent planning authority, that the possibility of structural use of the chosen plot is given. Common grounds for refusal are:

Lack of land dedication
Lack of building dedication
Nature conservancy
Lack of land development
Missing official border points

For sure you already know as a well-informed private individual: Each plot change must be approved by the building authorities (municipality). Save time, avoid troubles. The construction permission plan with current official border points will be required to secure neighborhood rights and to fulfill the required minimum distances to neighbours.

With official documents from your Civil Engineer for Surveying (IKV) the owner transfers the legal responsibility to the IKV and avoids expensive court proceedings. The actual house planning can now be started.

Current-state-plan and optimal plot-usage

As a basis for the first plannings, related to the current location, an architect needs a current-state-survey of the existing environment.

The resulting current-state-plan contains all relevant topografic planning elements (relief heights, vegetation situation, building situations including ridge and eaves heights, nearby roads, sewer pipes, ..), and the current-state of the cadastre.

The result is in general a 2D or 3D plan.
The delivery of a digital terrain model (DTM) or as a GIS dataset is no problem.
Bestandsplan

To identify and use favourable conditions for a construction site in a natural environment, examinations concerning the current lapescape (shadowing by mountains, houses, trees,..) at the corresponding location has to be done. With the help of in-house developed software astronomy programs the sun ecliptic is integrated into a locally taken panoramic photo. With this advanced planning basis the position and orientation of buildings and solar plants can be optimized.

Sonnenabschattung

The solar diagrams and sun cards allow exact day, month and year analyzes of the shade of the plot by the surrounding terrain. The diagrams and sun charts can be used for the purpose of energy use, building planning, regional planning and much more.

Building regulations - Prevent disputes

A prerequisite for the calculation of the border distance is the exact knowledge of the property boundaries. An Civil engineer consultant for surveying provides you with the necessary information.

In order to assess the minimum distance to the neighboring border (federal country specific), the planner must incorporate the height ratios of the site in his calculations.

Exactly information about the currently applicable spacing surface regulations you will learn here: www.bauordnung.at

Gesicherte Grundgrenzen

If the plan designed by the architect corresponds with the ideas of the client - the surveyor transfers the project to the current-state plan. Possible building regulations violations are corrected after a thorough review of the current laws. Construction work can start now.

Reference Line control and height controls

To make the necessary excavation for the basement efficiently, the stakeout of the excavation should be done.

The stakeout of the main corners ensures the rough location of the building. Furthermore, the volume of excavated material is determined.

Absteckung

Ask the Civil Engineer at the right time.

At the latest after completion of the base plate of the basement, it is strongly recommended and prescribed by law in many places to ask the Civil Engineer for his help. He certifies compliance with the location of the building relative to the property boundaries and compliance with municipal regulations of heights at the site. At this time it is still possible to apply small corrections. When the pit was dug wrong and the rising masonry is already constructed - the correction costs a lot of money and is also very time-consuming. The shunting of the house by hydraulic presses or deconstruction are then the only alternatives.

Surveying by Zivilgeometer creates safety- at the same time, the client has a certain proof in his hands that points were properly staked out handed over to the construction company.

Protracted conflicts between neighbors and the complication of a disposal situation (eg: pumping equipment at height errors) can be avoided. A broken roof can be repaired, a broken door can be replaced, but the wrong location or level of your home, except by dismantling, is irreversible!

Current-state-survey as a final dokumentation

Done - the house is built - Two things you should not forget yet.

  • Report the planning authority that the submitted construction process is finished.
  • Order a current-state-survey as a final dokumentation

With this plan of the Civil Engineer you have a legal protection that the house you have built coincides with the plans you sent the planning authority. Furthermore you have instant current and accurate planning documents. If you plan to modify something the architect can start immediately with this plans.
