Development of 3 d interfaces for mobile BIM applications by João Poças Martins

This presentation by João Poças Martins talks about information technologies (IT) evolved in a fairly significant way over the last few years, having its impact also reached the AEC industry (Architecture, Engineering and Construction). The modeling programs of Building Information Modeling (BIM) are presented as the next step in the cooperation and collaboration between the various actors in the construction site and between several specialties. However, there are still barriers to be exceed to its complete adoption in work because, not only of its complexity, but also due to fact that its usage is in personal computers so, in a fixed workstations. There is a necessity of bringing these models to portable workstations through simple and easy inter-faces that can be generated in game engines.
The present dissertation conducted an empirical study with the goal of finding a workflow between BIM software and game engines that would preserve the greatest possible amount of information. Af-ter finding a workflow that presented good results, it was proceeded to deepen this process, by explor-ing some of the potential of the game engine which can be applied to the interface. After this, the in-terface was built through a webpage.
At last, it was made a practical application of this methodology in a real building, exploring how the reunion of BIM models with game engines can contribute in a positive way to situations that involve teaching and security in work.

  13. 13. CONCLUSIONS  Mobile devices can play an important role in extending BIM use beyond the design phase.  Major BIM suppliers have presented solutions that are open enough for smaller developers to explore, mixing and matching information from different applications and sources. Small companies are not limited to “out-of-the-box” solutions.  Empirical testing is essential to assess suitability of available software and file formats.
