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.

2D PLANS

BASED ON YOUR REQUIREMENTS, WE USE THE SURVEY DATA COLLECTED TO CREATE AS-BUILT PLANS AT THE DESIRED SCALE

Once the survey is complete and the survey data has been recorded, we will contact you to clarify the requirements for plan analysis in detail. Among other things, we will work with you to define any plan templates, section levels, reference points, and other project-specific parameters. This ensures that all relevant specifications are clearly defined before we begin drafting the plans—resulting in a product that adheres to the project-specific requirements in terms of layout, presentation, and structure, and integrates seamlessly into your existing plan structure. We will deliver the final plans to you in DWG and PDF formats.

Floor plans are drawn directly from the point cloud at the desired scale and accurately depict the actual condition of the building—including slanted walls, varying wall thicknesses, and differences in elevation. The data captures walls, doors, windows, stairs, built-in fixtures, as well as plumbing and electrical installations. The section height is determined on a project-by-project basis, typically 1.30 m above the finished floor.
Sections show the vertical structure of the building: floor-to-floor heights, slab thicknesses, roof construction, stairwells, and level differences between floors. We determine the section locations together with you—typically through stairwells, atriums, or areas with complex geometry. The number and location of the sections depend on the planned intervention.
Facade views provide dimensionally accurate documentation of the exterior envelope: window axes and dimensions, cornices, balconies, parapets, and roof edges. For facades with intricate detailing or those designated as historic landmarks, the level of detail can be increased accordingly. The basis for this is scans of the facades, supplemented by drone imagery for roof surfaces and hard-to-reach areas.
Site plans show the building in the context of the lot: building outline, setbacks, access roads, paved areas, terrain contours, and landscaping. Upon request, we can georeference the data in the Swiss National Coordinate System LV95/LN02 so that the site plan can be directly overlaid with official maps.
