Reflections and criteria related to the creation of BIM models of historical buildings

Abstract

The main objective of this paper is to analyse the creation process of a BIM model applied to the field of historical buildings, taking into consideration their specific features in order to reach a successful and efficient use. For this purpose, three early medieval buildings have been studied. A specific modelling strategy has been applied to each of them and the research has been focused on several aspects, such as the level of formal simplification, the level of metric accuracy or even the level of development (LOD) properly adapted to the singularities of historical buildings. As result of this analysis, some conclusions are described, of which common thread is to propose keys to reach the feasibility of the application of the BIM methodology in the field of cultural heritage, both during the creation of the model and when using it.
