This process considers three key steps including the acquisition of data, enrichment of the 3D model, and segmentation of data. It is vital to highlight the BIM approach that starts to be largely used in the architecture field of design applied techniques to the available buildings, a concept referred to as the build BIM. The BIM process is made up of converting the geometry measurements and the appearance of the available buildings semantic rich representation. This process creation is depended on the initial phase of data and survey collection, and a second phase of treatment of data resulting to the last survey phase and collection of data. A second phase of treatment of data will lead to the last semantically enriched model. The previous studies have made the proposal that a number of approaches produce BIM using different techniques, while trying to make its generation automated.The techniques of acquiring data include photogrammetry, topometry, or laser grammetry. Topometry includes the traditional methods of doing surveys like using the optical telescopic sight, and taking the measuring system for the angular sight direction. The involved techniques result into high precision, which requires the system for the angular sight direction. The techniques would result with high precision that will require the vital quantities of work so as to find the significant structures of facilitating the post treatment. The technique will be considered being time consuming becoming more tedious whenever the objects appear complex In addition, photogrammetric is a method that uses the taken images from different points of view so as to build a 3D restitution of building and the scene. This technique adventure results from the point cloud that is enriched with the information on colour. This information would be helpful in reporting the conservation state and the historical buildings. The benefit of this technique is the point cloud that involves the enriched color information. This could be useful in informing regarding the sonservation state, in the case of historical buildings. The technique happens to be less expensive if compared with the lasergrammetry. Lasergrammetry is one easiest and speediest method. It involves a direct and relatime solution acquisition through the projection of the laser beam on the measured
