Drone to BIM: from aerial data to BIM models
Drone to BIM is a method in which drone surveys are used to convert existing buildings and sites into usable BIM models. By combining aerial data with photogrammetry and laser scanning, an accurate digital representation of the as-built condition is created. This approach is increasingly used for renovations, extensions, and complex sites where current plans are missing or incomplete.
How does Drone to BIM work?
Drone to BIM combines various measurement methods:
- Drone surveys for capturing roofs, facades, and surroundings
- Photogrammetry to convert images into measurable 3D data
- 3D laser scanning for extra detail and accuracy where necessary
The collected data is processed into a point cloud, which then serves as the basis for creating a BIM model in the desired LOD (Level of Development).
Why use Drone to BIM?
Accurate as-built condition
Drone to BIM makes it possible to digitally capture buildings as they actually exist, without assumptions or outdated plans.
Efficiency in preparation
By quickly collecting large volumes of data, this method significantly shortens the preparation time for design and renovation projects.
Better visualization and coordination
BIM models based on measurement data ensure fewer errors in design, better coordination between parties, and higher predictability during execution.
Example project: Dendermonde hospital
As an example project, a Drone to BIM process was carried out for the Dendermonde hospital. Using drone surveys and additional laser scanning, an LOD 300 BIM model was constructed.
This model served as:
- a reference for design and planning
- support for technical studies
- a basis for future management and maintenance
The project demonstrates how Drone to BIM can be deployed for large and complex buildings where precision is crucial.
When is Drone to BIM suitable?
Drone to BIM is particularly suitable for:
- renovation and repurposing projects
- hospitals and healthcare institutions
- industrial buildings
- campuses and large sites
For underground or water-related structures, this method is less suitable, and other measurement techniques are preferred.
