14 th International Conference on Computing in Civil and Building Engineering, June 27-29, 2012, Moscow, Russia Abstract Recent advances in building information modeling (BIM) have lead to productivity and quality improvements in the architecture, engineering, and construction (AEC) industry. As a result, several companies have spent significant effort in trying to implement, BIM technology, bringing attention to its difficulties in real practice. This paper proposes a practical method for systematically assessing BIM technology implementations at the corporate level. The method incorporates four main models: BIM perception, BIM adoption, BIM performance, and BIM capability maturity. These models were derived and consolidated from various existing BIM frameworks and approaches within the AEC industry. The BIM perception model assists top managers in assessing the perceived benefits, costs, and risks of their BIM investments. The BIM adoption model assists in formulating the BIM execution strategy by determining critical success factors (CSFs) of the identified BIM performance areas. The BIM performance model evaluates and establishes benchmarks for key BIM performance areas through key performance indicators (KPIs), which are sub-criteria of CSFs. The BIM capability maturity model defines the BIM performance levels of an organization. In addition, an assessment and evaluation procedure is provided to guide the evaluation. This approach attempts to provide a feasible and practical solution for assessing the BIM performance of an organization systematically, by considering both technical and non-technical aspects. Keywords: BIM performance assessment framework, BIM perception, BIM adoption, BIM performance, BIM capability maturity. 1 Introduction Building information modeling (BIM) is the process of creating and managing parametric digital models of a building (or infrastructure) during its lifecycle (Lee et al. 2006). In both academia and industry, BIM has been acknowledged as a new approach that can improve productivity and quality in the construction industry (Smith and Tardif 2009). However, the growing adoption of BIM technology is unlikely to be sustained if the synergy between BIM, integrated project delivery (IPD), and sustainability (Kent and Becerik-Gerber 2010) is not addressed. Additionally, deploying BIM technology necessitates significant changes in widely adopted business practices in the AEC industry. These changes involve both technical and non-technical aspects (Gu and London 2010; Azhar 2011). While technological interoperability has made significant progress, business interoperability is still limited at present (Taylor and Bernstein 2009). To assist business owners in assessing and aligning BIM with their defined strategy (Smith and Tardif 2009), an integrated performance assessment approach is needed. This paper attempts to address these current challenges in implementing BIM technology by proposing a practical assessment approach that can bring to maturity the implementation of BIM technology in the AEC industry. The approach is called the, BIM Toward performance assessment of BIM technology implementation Mony Mom & Shang-Hsien Hsieh Department of Civil Engineering, National Taiwan University, Taipei, Taiwan
