It is stated that 3D recording and modelling of heritage buildings entails accurate building models (as-built). However, this paper presents an analysis of the 3D modelling accuracy for the creation of historical building information models (HBIM), considering the complexity and the deformations of historical buildings, using point cloud data and BIM tools. The 3D modelling processes analysed are based on a three-stage semi-automatic approach leading to the generation of HBIM, including manual and automatic processes. The three stages consist of: (a) optical and terrestrial laser scanning; (b) meshing processes; and finally (c) 3D solid modelling to be assembled into HBIM. Next, this approach analysed the mesh deformations generated automatically in comparison to the initial point cloud data. The deformations and the accuracy evaluation have been undertaken using different commercial software. Finally, our modelling approach shows that it can improve the accuracy of the 3D models achieved using existing BIM technologies.
