Abstract:

Building Information Modelling (BIM) has been implemented by various Architecture, Engineering, Construction and Facilities Management (AEC/FM) firms in various countries due to inefficiencies in traditional construction project management practices. AEC/FM organization require to gauge the effectiveness of their BIM implementations for measuring their performance and enabling continuous improvement in BIM usage. Therefore, various BIM capability and maturity models are developed to help organizations achieving different BIM assessment purposes in AEC/FM industry. Due to the differences in applicability and focus of these models, they meet the demands of different BIM users. Thus, there is no commonly accepted and broadly used BIM capability assessment model in the AEC/FM industry. Furthermore, various types of facility information are generated and used by different stakeholders in different facility life cycle stages. Fragmented structure of construction projects require assessing BIM implementations based on specific processes. Nevertheless, the models in literature, do not enable process based BIM capability assessments. In this study, a reference model for assessing BIM capability of AEC/FM processes, which is called BIM-CAREM, is developed. BIM-CAREM is composed of two parts which are BIM Process Reference Model and BIM Measurement Framework. In the first part, key AEC/FM processes have been determined and defined in terms of process purpose and BIM outcomes. In the second part, BIM capability levels, associated BIM attributes, and a rating scale have been defined to be used during assessments. BIM-CAREM is developed based on the meta-model of ISO/IEC 33000 and later, an iterative development is performed through expert reviews and an exploratory case study. Finally, it is tested in four different firms using multiple case studies method. The results indicate that, BIM-CAREM is capable of covering key processes of facility life cycle and that BIM capability levels and BIM attributes are suitable for identifying BIM capabilities of different processes of organizations at various capability levels.
