The instrumentation and structural health monitoring has gained a growing importance in the construction industry. However, the resulting data has not been properly handled. In order to correct this factor, is intended to integrate the data collected in information management systems such as BIM. The BIM is based on the idea of integrating all information related to a building or project in a single digital model. This information can be associated prior or during construction of the building or even during its lifetime. These tools have developed rapidly, increasing their chances of information management.
The purpose of this study is the information management from the instrumentation and structural health monitoring. As to achieve this goal, it was studied a standard construction model, with the use of a common language. This model is referred as IFC. In this work is performed an assessment of the applicability of the IFC model, as a format for information exchange between sensors and BIM. It was proposed the extension of the model based on kinematic sensors, since it only includes environmental sensors.
Based on the model above, and using BIM programs, there was a real case study concerning the building of the ―Nave do INEGI‖, using data from actual measurements. It was conducted a three-dimensional model of the building, studied the interoperability between various BIM tools and compatible properties were created within the IFC model capable of delivering the information recorded by the sensors.
Thus, it was studied the issue of the instrumentation and structural health monitoring framed on the BIM software on a scale closer to the real, where the adversities and the problems substantially differ from those presented theoretically. The results suggest that the management of information from the BIM with the data obtained by the sensors becomes achievable.

  15. 15. Conclusions  It is possible and relevant the introduction of data information obtained from SHM into a BIM model, through the current IFC configuration;  The definition of a robust model does not guarantee the success for the exchange of information on construction industry;  The standard models should be complemented by partial models or extensions to the model itself, for more specific contexts;
  16. 16. Conclusions  The IFC model is an adequate support for interoperability, but still needs to be complemented;  The tested applications were not able to handle the entire shaping conveniently.
