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.

laserscanning

With passion and modern technology, we measure single-family homes, multi-family homes, retail spaces, and industrial facilities contactless and with millimeter precision.

We use 3D Laserscanning to measure buildings of all types precisely, comprehensively, and without contact. Depending on the project requirements, we also use drones (terrain, roof landscapes), GNSS, or Totalstations. The resulting pointclouds form the basis for the creation of reliable and robust planning foundations—from 2D plans to 3D models in CAD.
If you prefer to evaluate the survey data yourself, we can supply you with the registered point clouds optimally prepared for import into your CAD system.

With 3D laserscanning technology, buildings, structures, and construction sites can be digitally measured with millimeter precision. To do this, a 3D laserscanner is mounted on a tripod and set up at different locations to scan all visible surfaces as completely as possible. The laser rotates around its own axis, capturing up to 2 million measurements per second.

The pointclouds from the individual setup stations are then cleaned up using powerful computers and special software and registered to a project pointcloud. This forms the basis for the subsequent evaluation to create 2D plans and 3D models in CAD.
Totalstations operate with a single laser that is directed at the target to be measured. The totalstation can measure both the horizontal angle and the vertical angle, allowing the position and height of the point to be determined with maximum precision.
Drones are primarily used for surveying topography and roof landscapes. As it flies overhead, the drone generates countless photos, which are then evaluated using powerful computers and special photogrammetry software to create point clouds and orthophotos. The drone surveys large areas in a short time, but the measurement precision is significantly lower than that of a 3D Laserscanner.
A GNSS (Global Navigation Satellite System) receiver is a device that receives satellite signals from multiple satellite systems (GPS, GLONASS, Galileo, and BeiDou) to determine its own position. The absolute accuracy of position determination is typically in the range of several centimeters (XY 1-10 cm, Z 5-15 cm).
