Point Cloud system in BIM enviroment

High-definition survey using a laser scanner (HDS) is an irreplaceable tool for data collection to work in a BIM environment.
The file that is generated is known as a “point cloud” and is an exact 3D reproduction of the building, with as much resolution as one needs. This method offers us a much more complete measurement of the building on which we are going to intervene than the methods traditionally used by CAD. The possibility of superimposing this information on our BIM model allows us to obtain exact and parameterized information of the current state, anticipating many decisions and solutions in the project phase instead of having to improvise them on site.
The example we show is a 16th century building on which we are going to intervene, and it would be impossible to obtain the exact position, shifting, damage and geometry of each element without this tool.
