Implementation of lean practices facilitated by BIM functionalities in the construction phase: advances and opportunities

Abstract Over the past few decades, construction productivity has been at a standstill. Lean and Building Information Modelling (BIM) is attracting increasing interest in the construction industry as a way to increase construction productivity. This paper aims to contribute to the body of knowledge by identifying hitherto unexplored opportunities for the use of BIM functionalities as a support and as facilitators of the application of lean practices in the construction phase. A systematic literature review was adopted as the methodological approach in this research, and reported case studies related to the scope of this paper were searched. The results show that lean practices can be classified into four degrees of BIM support based on the level of current exploration. Just one lean practice (the last planner system) has been extensively explored, three have been reasonably explored, and five have just been preliminarily explored. Five practices have not been explored at all. This research summarises the already studied and the potential additional uses of BIM functionalities to support each lean practice, showing that lean practices supported by BIM functionalities are still underused and that further studies can explore additional ways to support these practices. This study holds great value for a broader practical application of lean practices, bringing faster and easier results with more extensive BIM support.
