BIM can be used in the area of finding functionality and estimating visualization work. It can be even used for vaious aspect of analysis such as wind analysis for soffit design work.
See the attached youtube video regarding the implementation of BIM during construction.

There are other things that can be added into the BIM during the construction phase as well. One could laser scan each room prior to covering the walls to capture the routing and location of electrical conduit, piping etc. so that one can provide more accurate "as built" information to the model. Technical information such as exploded parts lists, guarantee or warranty information, maintenance schedules, operations manuals, check out and testing information, lube maps etc. can all be attached to the objects in the BIM model for later use by the facility manager.
The BIM collaboration format also has the potential to capture tacit knowledge and make it searchable, assuming it is widely adopted at some point in the future. I saw a paper presented at WBC 16 on data mining/textual analysis of those files that had a similar intent (Kuo, V, Oraskari, J,(2015). A Predictive Semantic Inference System Using BIM Collaboration Format (BCF) Cases And Machine Learning. Submitted to In CIB World Building Congress 2016. Tampere, May 30 - June 3, 2016.
