In part one of this two-part entry, we saw how BIM is still difficult for smaller projects (such as detached houses) that have been highly customized. In this entry, I am showing the changes that were made after surveying the building. In most cases, this made the project easier to draft. In other cases, the limitations of BIM became obvious once I discovered the reality behind the way different features were constructed, many of which were not obvious from the hand drawings mentioned in part one. And all the mistakes are still obvious when examining the 3D model. The 2D drawings that BIM creates are still solid when you have the true dimensions of the rooms, which is much easier to achieve by visiting the site and measuring the project than by drafting from someone else's (non-BIM) documentation.
