Week 3 Class Discussion - Group B - Current Problems with Revit/BIM

We have discussed many current problems with Revit and BIM modeling based on our experiences.

Firstly, just as Kayleigh mentioned, he Phasing of projects has very little capability without making new models. It can get tedious and hard to make sure you are not interfering work between each construction phase.

Another problem that we have observed is that the file size can become very large very quickly and the computers cannot handle those files. Revit Models frequently crash and lag behind - this is both an issue in compressability and the massive amount of information in the model. It would appear that the code is not optimized and is hard on your graphics card to handle.

The next problem we discussed is that we notice the Electrical Engineering field has not had attention in the BIM - it is hard to model because of all the components and there are not these quick fixes that we may see in MEP models. Turning the 3D model in to a 2D CAD printed drawing to be used in construction is also sometimes difficult - lines don't translate as well as symbols do and there is this "double" work that technicians are doing, one for the 3D and one for the 2D.

We also feel that it takes longer to understand the Revit model - it takes more time to set it up in the beginning of the project and may come more easily at the end. Because it is so powerful, there are so many features and it is complicated - so balancing an easy user experience to the capabilities could be improved.
