A SYSTEM DYNAMIC MODELLING APPROACH FOR INTEGRATED LEAN-BIM PLANNING AND CONTROL METHODS

Abstract

Traditional planning and control methods do not accurately reflect the construction reality and lack feedback loops. The Last Planner System (LPS) and Location-based Management System (LBMS) have been suggested as socio-technical systems to generate practical and actionable real-life data based on production theories and logic. This data can be effectively communicated, analysed, and managed using the capabilities offered by Building Information Modelling (BIM) workflows. However, a true integration between Lean Construction-BIM is not yet matured, where parallel use of both concepts is still more common. This paper presents a conceptual framework based on a system dynamic modelling approach to elaborate a causal loop diagram (CLD). The CLD explores the interactions between basic management functions and waste, on this basis this paper proposes how the integration between LPS, LBMS, and BIM can be harnessed to apply waste elimination strategies. The results of this study can be applied as lean policy analysis for new lean adaptors to understand the impact of Lean-BIM for planning and controlling various wastes across the construction supply chain.
