Architectural Information Modelling for Virtual Heritage Application

In today’s AEC industry (Architecture, Engineering and Construction industry), there has been a vast evolution in the usage of information and communication technology (ICT) for describing and managing construction projects. During the past years this led to the elaboration of the technique Building Information Modelling or BIM for describing buildings and building information according to their different composing elements. One of the major advantages in this BIM approach is the possibility to use this building information for calculation, simulation and analysis in related, more dedicated ICT applications. Starting from the building information model, these applications are accessible through an interoperability language, namely the Industry Foundation Classes (IFC), elaborated by the International Alliance for Interoperability or IAI. This paper proposes the development of an approach similar to BIM, namely Architectural Information Modelling (AIM), which describes more theoretical and historical building knowledge instead of the explicit and component-based descriptions inside BIM. It illustrates several possible advantages of this AIM approach for application in building documentation for virtual heritage, combined with possible historical analysis tools. It also makes a short comparison of this technique with procedural methods, a similar technique that is gaining much interest during the past few years in the domain of virtual heritage. Finally, this paper proposes future research ambitions and some conclusions of this first, conceptual research about an architectural information modelling approach

A nice thing about standards

The paper documents the implementation of automated data exchange process as an alternative to the manual workflow an architect needs to go through if he wants to comply with the EPR and acoustic regulations imposed by recent Flemish standards. This application is able to import specific IFC files and interpret its information. It automatically acquires the information needed and performs the calculations. The results of the calculation are then displayed through a user-friendly interface, to enable a designer evaluate his design and immediately make improvements to his model. This application was tested in a case-study using an exemplary BIM model. The overall functionality of the communication process from BIM to the application is analysed and the resulting concerns are outlined
