The use of 3D laser scanning has been used in the construction market for Brownfield projects. Mainly in the industry works sector with large investments, as an alternative to physical field surveys that require one or more professionals to travel to the site of the intervention work to produce the as-built document. Traditional as-built documentation is not only costly, but can also present inconsistencies and documentation difficulties, such as the inaccessibility of an operator at a given location, which can be avoided by using a point cloud to produce a 3D as-built. The 3D as-built consists of a 3D model executed using BIM methodology in which the information base is the point cloud. In addition to being more accurate, the model can be used for simulations, augmented reality, simplified documentation and contribute to the digital twin of an industrial plant. This end-of-course work has carried out a study on the feasibility of the point cloud for as-built based on a theoretical review of the subject, together with statistical analysis experiments to determine the model's accuracy. A cost-benefit analysis of traditional as-built was also carried out to compare the two methods
