*6.3. Limitations and Future Studies*

This paper focuses on the project BIM application maturity. The limitation of the paper is that it does not research the organizational BIM capability maturity. Similar research of the organizational BIM capability maturity can be carried out in the future. In addition, this paper takes an engineering company engaged in general contracting business as an example; however, the effect of BATM application to design or construction enterprises needs to be further validated.
