Several Building Information Modeling (BIM) activities can be managed efficiently through Alteia, leveraging reality captured and processed in Alteia (nadir roof and vertical facade, orthomosaic, 3D models, annotations) and building theoretical data, from 2D or 3D CAD files. This is notably the case for as-built vs. as-designed comparative analysis.

2D as-built vs. as-designed Analysis

A CAD file is ingested (building floor plan) and overlaid on the 2D real layer (orthomosaic of the building roof processed by Alteia from a drone survey).

3D BIM is compared to real 3D model as well.
