Representación del dibujo frente a simulación de los sistemas BIM. Oportunidad o amenaza para la arquitectura

The aim of the paper is to establish the respective role of drawing and BIM model as representation or simulation in architecture. The breaking in and generalization (at all levels) of BIM systems in the professional world of architecture and construction, calls for a reflection based on experience and rigorous analysis, to establish the risks and opportunities that it entails. Methodology: Based on their experience in critical analysis of technological innovations applied to architectural representation as well as in the use of digital tools on BIM platforms, the authors establish some concepts to approach their use in architecture. Conclusions: A BIM model includes all information that may be assigned to each construction element and presents a simulation of the complete project. Therefore, it can become a tool that makes easier to control and evaluate the quality of the performance of an architectural project. It can be transferred to the different parties involved throughout the development and construction of the project and allows for modifications and continuous improvements. But in each phase, each party will need to filter, select and hierarchize the information to represent certain aspects of the architecture. In this phase, they might recover tools typical of traditional architectural representation. Originality: This paper follows others by the same authors in which they analyze the effects of the break-in of the CAD systems applied to architectural drawing. We believe that we should reflect calmly and without prejudice on other new technologies that arouse suspicions in some and dazzle others. [-]
