Progressive digitalization of big organizations makes evident the necessity of better data integration. Ontologies and data structures can be connected thanks to mutual agreements and over digital information, resulting in a massive availability of data and knowledge.

Any professional can be attracted by the great possibilities that these may be offering to the building sector. But progress is only possible if a great number of stakeholders adopt standards and common procedures.

Whether if you are a BIM manager, a software developer of a manufacturer of appliances, for sure you will be surrounded by a technological pressure which makes you feel comfortless many times. BDTA is an effort to build a common frame ahead of BIM and others standards, promoting agreements, sinergies and public libraries to get a better construction: healthier, more comfortable and sustainable. With a lot of ambition and creativity.

We have prepared 4 initial working groups oriented to roles and agents (WG1), ontologies (WG2), technology aggregates (WG3) and simulation (WG4). BDTA organizes an annual congress and is already participating is some EU proposal towards privacy and standarization of simulation components. Please contact us for more detailed information.
