The construction industry, as a driving force for economic development, has always faced numerous challenges such as rising costs, frequent delays, waste of resources an‎d inconsistent quality. In response to these inefficiencies, two approaches, “Lean Construction” an‎d “Building Information Modeling (BIM)”, have been considered as transformative paradigms. This study believes that the purposeful integration of these two approaches can lead to creating synergy an‎d achieving a new level of productivity an‎d quality in projects. This study was conducted using a mixed research design an‎d a descriptive-analytical approach. The required data were collected through library studies, semi-structured interviews with 18 experts, an‎d the distribution of a researcher-made questionnaire among 200 managers an‎d specialists in the construction industry. Thematic analysis was used to analyze qualitative data, an‎d structural equation modeling (SEM) with SmartPLS software was used for quantitative data. The validity an‎d reliability of the research tool were confirmed by Cronbachʹs alpha an‎d composite reliability indices. The quantitative findings of the research showed that the integration of BIM an‎d lean principles can reduce project time by 30% an‎d costs by 25%. Also, this integration leads to a 40% reduction in waste an‎d 35% in implementation defects. On the other han‎d, a 42% improvement in planning accuracy an‎d a 35% increase in the Program Performance Index (PPC) were other notable results of the present study. Qualitative analysis also identified five main themes of “technical infrastructure”, “organizational factors”, “human factors”, “legal framework” an‎d “economic factors” as essential prerequisites for this integration.
