"3D laser scanning technology is a way to acquire and register geometric and geographic data of objects, buildings and urban centers faster and more accurately, and can be applied to detect conflicts, obtain quality control, create "as built" and "as is" models.

​

The use of BIM technology comes to the fore as a way to represent and manipulate this information acquired by scanning in a more consistent and integrated manner, allowing a series of studies and simulations of the construction throughout its life cycle."

The comparison of the design with the point cloud can be performed with BIM designs, CAD designs, or even photos. Due to the high flexibility that the point cloud offers with respect to sections, elevations, and plans at different levels, it is possible to generate the view required for comparison, or even insert the model and the cloud into compatibility software to identify differences or interferences.

​

The uses and advantages are countless and that is why the application of 3D laser scanning in construction is spreading more and more each day.
