The document discusses Building Information Modeling (BIM) and its next level. It aims to discuss BIM-1, which is Building Information Modelling, and BIM-2, which is Building Information Management. It compares the construction processes for small and large projects, noting that large, modern commercial high-rise buildings now utilize primary consultant teams, 3D models, and 3D BIM models, whereas small projects traditionally used 2D drawings. The document argues that modern production of large commercial buildings now faces similar challenges to increased complexity as modern industries like automotive and aerospace.
