Framework of digital lean construction and implementation of its management platform for the construction phase

In order to solve the problem of lack of appropriate tools in the lean construction of construction projects, a framework of digital lean construction is proposed as a whole, and its management platform is implemented for construction phase by integrating lean construction with digital technologies. The concept of digital lean construction is proposed, its management model is constructed and refined, and the corresponding management platform is implemented for the construction phase. The framework is verified by holding an expert workshop and applying the management platform to typical construction projects. The research contributes not only to the establishment of the theoretical foundation to upgrade lean construction, but also to accelerating the transition from lean construction to smart lean construction. Two directions of future research are expected, i.e., to enhance the integration of the lean tools and digital technologies and clarify the transition to smart lean construction.
