Wie funktioniert eine 3D Gebäudevermessung?

We primarily capture your building using terrestrial 3D laser scanners. The scanner is set up in every room and in front of the facades, capturing up to two million 3D data points per second. Using specialized software, we combine the individual scans into a comprehensive project point cloud—a digital representation of your building accurate to the millimeter. We then use this data to create the desired 2D floor plans or 3D models in CAD.

Wie genau ist die Laservermessung?

Our scanners have a measurement accuracy of ±2–3 mm at a distance of 10 meters. The point cloud captures your building with millimeter precision—including all irregularities such as crooked walls, sagging, differences in level, or asymmetrical window reveals.

Wie lange dauert die Aufnahme vor Ort?

The duration depends on the size and complexity of the property. As a general guideline: a single-family home takes ½ to 1 workday, an apartment building takes 1–2 workdays, and larger properties take 2–5 workdays. We will provide the exact duration in our quote.

Müssen Möbel und Einrichtungen entfernt werden?

No. Only objects that completely cover load-bearing structural elements should be moved temporarily, if possible. In practice, this is rarely necessary.

Welche Ergebnisse erhalte ich nach der Vermessung?

From the point cloud, we can generate the following drawings: 2D floor plans, 2D sections, 2D elevation views, reflected ceiling plans, site plans, 3D CAD models, 3D BIM models, point clouds for digital as-built documentation, as well as 360° photo documentation and 3D web viewers.

In welchem CAD-System liefern Sie?

We deliver files in formats compatible with ArchiCAD (.pla/.pln), Revit (.rvt), Navisworks (.nwd), and AutoCAD (.dwg). Upon request, we can also work directly with your office template.

Was kostet eine 3D Gebäudevermessung?

Costs depend on size and complexity. Estimated prices: Single-family home survey + 2D plans starting at CHF 4,500, single-family home 3D model LOD200 starting at CHF 6,000, multi-family home survey + 2D plans starting at CHF 7,500, multi-family home 3D model LOD200 starting at CHF 10,500. We offer fixed, all-inclusive prices with no hidden costs.

Braucht es für die Offerte eine Begehung vor Ort?

No. In most cases, existing documents (old plans, photos, sketches) that include the address and a brief description of the property are sufficient. We will provide a non-binding flat-rate quote within 72 hours.

Was ist eine Punktwolke?

A point cloud is a three-dimensional representation of a building consisting of millions of individual measurement points. Each point has precise spatial coordinates (X, Y, Z) and color information. The point cloud captures your building exactly as it is—with all its variations and irregularities. It is permanently preserved as digital as-built documentation.

Werden die Daten georeferenziert?

Upon request, we can georeference the survey data in the Swiss national coordinate system LV95/LN02. If georeferencing is not required, we use a local project coordinate system.

3D models

We use the survey data obtained to create 3D building models.

After surveying and recording the data, we will contact you to discuss the requirements for the upcoming 3D modeling in detail. During this process, we will jointly define, among other things, any design drawings, the level of detail for the model, reference points, delivery times, and other parameters. This ensures that all specifications are clearly defined before 3D modeling begins.
We deliver the final 3D model to you in the agreed-upon CAD format (.pla, .rvt, .vwx), and upon request, also in IFC format for exchange with any specialist planners.

We model natively in the CAD program of your choice to rule out compatibility issues from the outset. We are also happy to use your CAD office template.

When it comes to 3D modeling, the question arises as to how detailed the existing structure should be depicted. On the one hand, true-to-life modeling enables an exact representation of the existing structure, but at the expense of a "heavier" model with morphs, which is less efficient to work with than a 3D model with a certain degree of abstraction.
We therefore work with you at an early stage to determine the appropriate level of detail for your project and tailor the modeling specifically to your requirements and the planned evaluations.
The required level of detail is project-specific and should be determined during the quotation phase, as it has a significant impact on costs. We will provide you with a graphical overview of the different LOD (Level of Detail) levels so that you can realistically assess your needs:
- LOD 100 (1:100 with reduced detail depth)
- LOD 200 (1:100)
- LOD 300 (1:50)
- LOD 350 (1:20)
Different LODs can, of course, be combined within a single project. It is also possible to upgrade models to a higher LOD at a later stage if required.
The time required for 3D modeling is often underestimated. Early building surveying and allowing sufficient time for modeling and evaluation are prerequisites for successful collaboration.
