An initial assessment was undertaken followed up by a drone flight to capture images for analysis. The 2D drone images were stitched together by use of photogrammetry to create an overall 3D pointcloud survey. The pointcloud was then loaded into our structural documentation package (Revit) to create an overall 3D model and produce drawings. This was the first time we used a drone survey to create a 3D pointcloud, something we do on a daily basis now.
