###### Abstract  
Many researchers have stated that lean and building information modeling (BIM) have positive synergies. This integrative literature review aims at exploring this body of knowledge within the scope of combinations of BIM and the Last Planner(r) System, as an important Lean construction method, in the phase of construction execution. The research motivation is to find out whether a comprehensive understanding of how to take advantage of these synergies exists. Eventually, the question arises of how to condense this understanding--if existing--into a robust conceptual model for integration. As a theoretical backbone, we will make use of the original BIM-Lean interaction matrix. The hypothesis is that new BIM functionalities have been evolved since the first formulation of this interaction matrix almost 10 years ago. These new BIM functionalities cause new interactions with existing lean principles. We will focus on interactions that refer directly or indirectly to production planning and control and use them to find the most relevant literature for this review. Within the content analysis, as a part of this review, we focus on existing conceptual models and frameworks for integration of BIM and the Last Planner(r) System and reveal their shortcomings. Eventually, we will propose a new conceptual model. BIM; lean construction; production planning and control; data-driven construction 2020 10 821 12.12. Over time, connotation has evolved with the term and is now also used to represent digital innovation in the construction sector [3]. At the same time, the movement of lean construction management (LCM) has established itself on the level of construction process management as an adaptation of lean production from the automotive industry and is gaining more and more influence in today's construction management practice [4]. This resulted among others in new methods for design and/or site management such e.g., the Last Planner(r) System (LPS) but also in holistic project management and delivery approaches, such as e.g., integrated project delivery (IPD) concepts [5]. The principles of lean philosophy are primarily aimed at maximizing value for the customer by eliminating non-value-adding activities referred to as waste [6; 7]. In lean jargon, basically, everything that is not needed is considered as being waste [8]. BIM can help to define what is needed and thus help to identify and remove waste, since it can precisely--digitally--describe what, how much and in which quality is needed on-site. The latter refers already to an often-cited positive interaction of BIM and Lean [9; 10; 11]. These positive interactions--or in other words, synergies--are receiving more and more attention in both academia and practice [11]. This tendency of the growing importance of both movements can also be seen in the increasing number of scientific studies over the last 16 years in both fields BIM and Lean Construction as depicted in Figure 1.  
The indicator of scientific publications clearly shows the proactive role of the AEC-industry in the adoption of both BIM and LCM [12]. It can be also seen that especially the number of BIM publications is growing steadily and rapidly. On the one hand, this is due to the general trend towards digitization in our society today. On the other hand, it is also and particularly due to the pressure triggered by legal and social requirements to increase productivity and efficiency. This is why the discrepancy with other industry sectors is still very large, but the construction industry, however, accounts for a very important share of the economic performance of industrialized countries [12; 13]. BIM is seen here as a key technology [14]. This is also made clear by the fact that in many countries BIM will be mandatory in the near future for the planning of public-sector projects [15].
