###### Abstract
Figure 1: Building information modeling (BIM)/Lean construction papers published: 2003–2019; (data retrieved from the Scopus Database; search terms TITLE-ABS-KEY ((“building information modeling” or “building information modelling”)) and (“lean construction”)). In addition to the growing popularity of both approaches, it is important to emphasize that BIM and Lean are in principle independent of each other and could be used concurrently [16]. Nevertheless, the scientific community and also practitioners are certain that (new) BIM functionalities can generate numerous interaction effects with the existing principles of the lean philosophy. In most cases, these can be considered as positive synergies and thus add value to the construction industry [10]. Considering this potential added value of an integrated BIM-lean adaption, interest in combining both approaches has arisen in the scientific world in recent years. The resulting synergies have been brought to the surface, both through scientific-theoretical treatises [10; 17; 18; 19] and by proposing BIM-Lean supporting IT systems [20; 21; 22; 23]. On the theoretical side two works deserve special mention in this context. : the original work of [PERSON] et al. [10], who describe the combination of BIM functionalities and Lean principles in an interaction matrix, and its update from [PERSON] et al. [9], which together form the basis of numerous scientific publications in the tension between BIM and Lean, we will make use of the original interaction matrix as a guideline for this literature review. More specifically, it will serve as an a-priori filter for the identification of relevant literature in the scoped area of BIM-LPS combinations in the construction phase. It will also help to analyze only papers dealing with on-site production that combine both approaches. The rationale for limiting this review to the Last Planner(r) System rather than considering lean construction, in general, is explained in more detail in Section 1.2. On the one hand, this review aims at finding out to what extent the interactions that were attributed as \"cannot be considered mature technology\" in 2010, when the original interaction matrix was first published, have evolved over the last decade. In addition, it will be also analyzed where still existing gaps in terms of technology maturity could be closed with new BIM-Lean IT systems to be developed in the future. On the other hand, we claim that within the last 10 years the BIM functionalities have expanded and that the possibilities of using the information available through BIM are no longer reserved for IT specialists only, but have also opened up for architects and engineers through the introduction of e.g., visual programming languages (VPL). Consequently, these new functionalities also result in new interactions with existing lean principles, which are formulated in this study and serve as a \"lens\" for this literature review, too. In summary, and as a starting point for this literature review, it can be said that numerous studies have been published in the field of BIM-Lean interaction. The present inadequacy, however, is that there is much literature on synergies but--to our best knowledge--no summarizing review for the specific case of BIM-LPS integration in the phase of construction execution. This study inserts in this niche and aims at disclosing the relevant body of knowledge within this scope. This goal is pursued by means of the research method \"integrative review\", which will be guided by the original BIM-Lean interaction matrix as theoretical backing. The body of this review article is organized as follows. Section 2 explains the applied research strategy for conducting this review. Section 3 provides the details of the followed review protocol allowing for replication of the procedure. Section 4 contains the actual results of the review in terms of a description of the final literature sample, a qualitative content analysis, and implications.
