Structural Equation Model of Building Information Modeling Maturity

For the implementation of building information modeling (BIM), an incompatible development among various aspects of a business can lead to different levels of BIM maturity (BIMM) or even project failure. Therefore, it is important to identify key causal factors of BIMM. This research develops a structural equation model of BIMM through three-step multivariate analysis. It starts with exploratory factor analysis to identify three key BIMM factors, which are further tested with confirmatory factor analysis. The causal relationships among the three factors and BIMM are then proposed and validated with structural equation modeling. This research has both practical and theoretical contributions. Practically, the proposed model can be used by practitioners to initiate and evaluate their BIM implementation. Theoretically, the result provides empirical evidence for the multidimensional nature of BIMM and insights into the causal relationships among the factors. Specifically, the factors of process management and technology management are correlated, and both have significant positive impacts on BIMM through the information management factor. However, compared with technology management, process management is identified as more important for BIMM.
