Conversion free data exchange is feasible in construction industry

This doctoral research was carried out about a conversion free data exchange in the construction industry. Current data systems are differing and incompatible with each other, which compels to the use of conversion with data exchange. Data loss, altering and overlapping are common problems with conversions.

The main result of the research was that no technical impediment exists for the conversion free data exchange. On the research, a scalable data model and a single shared database as a cloud service were developed and tested. One data format and one shared model make conversions irrelevant. The complexity also decreases when only a single data schema and model are used.

The method presented in the research is not directly compatible with current systems, but changes are required on existing applications. However, a conversion-free single shared model approach can be a possible trend to the next generation BIM as well as a potential alternative for current data sharing methods using distributed files, conversions, and linked data.
