A model of BIM application capability evaluation for Chinese construction enterprises based on interval grey clustering analysis

Abstract

Application of BIM plays a key role in the practices of architecture, engineering and construction. Evaluating and improving BIM application capability have important effects on increasing BIM performance and enhancing the benefits of BIM usages. To evaluate the BIM application capability of construction enterprises, this study proposed an evaluation model based on interval grey cluster analysis (IGCA). Firstly, the study constructed an assessment index system of BIM application capability from three dimensions, including technical, organization and management, and human aspect. Secondly, BIM application capability and its evaluation index were divided into four levels. Thirdly, in order to determine the index weights, the interval-entropy weight method was applied. Then IGCA was applied to identify the BIM application capability. Finally, a case study was conducted to explain the application of the proposed model and to verify the validity of the model. The results indicated that the evaluation model could provide a new way to evaluate and improve BIM application capabilities.
