Building Information Modeling (BIM)

You can manage several Building Information Modeling (BIM) activities with Alteia, as the platform is built to manage real-life data inputs such as orthomosaic data, 3D models, and annotations as well as building theoretical data from 2D or 3D Computer Aided Design (CAD) files. This functionality is especially useful for analyzing as-built information with as-designed documentation.

3D Reconstruction of Assets and Buildings

In order to build an accurate digital twin of an asset, you need 3D point cloud data and ground-based camera images. Using the built-in Pix4D photogrammetry engine option, you can process RGB pictures for this purpose.

  • In the example below, a facility building is reconstructed in 3D from a dataset of 232 images gathered with a DJI Phantom 4 RTK drone.

Display the 3D view by clicking on the red boxed button below.

Then display the point cloud framed in yellow to get a 3D representation of your images. Please note that if you have not reorganized your layers, the point cloud file will be in the "Base Layers" section.

  • In this example, 479 images were used to recreate this infrastructure in 3D.


2D as-built VS 2D as-designed analysis

To create an as-built VS as-designed analysis on a structure, a CAD file is ingested (for example, a building floorplan) and overlaid on the 2D real layer (for example, orthomosaic of the building roof processed by Alteia from a drone survey).

3D as-built VS 3D as-designed analysis

The comparison can also be done in 3D view. For this, you can visualize both the point cloud created by the drone flight and the CAD model.

Then, a point cloud difference can be performed. To do this, run the "PCL Difference" analysis available in the "Free Analytics" section.

Below, 3D BIM is compared to a real 3D model. In blue you will find the identical points on both models. In red, are the points which do not correspond between the two models (corresponds here to points not modeled by CAD).
