    [EN] The basis of this project is to implement the use of laser scanner to analyze structural deformation in construction and its subsequent modeling to complete the 3D model of a building. The advantages of a measurement are analyzed with high accuracy, non-invasive and whose results can be implemented in BIM, evaluating the deformation of structure in real time and being able to incorporate the existing geometry, detecting interferences between architectural or MEP installation elements and the model. In opposition to the operational complexity of the evaluation of load testing on structures and their impact on the management of the project, this method does not interfere with the work due to the fact they are executed in a few minutes and can be repeated at different times without any impact. The laser scanner has been used with estimated error based on a working distance of less than 0,20 mm and a reinforced concrete structure under construction; specifically, we study the deformation of a cantilever of 3.50 m, scanning at different moments of its loading, measuring the deformations. Point clouds have been compared and analyzed by CloudCompare©, and imported into Revit to model the structure. The workflow and process standardization are detailed for general application
