1. Determine a methodology for modeling an existing building in BIM. 2. Determine the methodology to evaluate the process of modeling and existing building in BIM: data missing, software problems, standardization of data, etc. 3. Gather information about the building to model (drawings, databases, projects, etc.). To do this, the Campus Terrassa’s maintenance department will provide all the available information. 4. Develop the BIM model. 5. Evaluate the implementation of the BIM model: Advantages, drawbacks, etc. 6. Conclusions
