A Holistic Evaluation of BIM Implementation Barriers in the Indian Construction Industry: Pre- and Post-Adoption Perspectives.

The existing Building Information Modelling (BIM) research does not provide a holistic understanding of pre- and post-adoption barriers to its implementation, especially in developing countries such as India, where BIM adoption lags. First, a total of 32 barriers to BIM implementation were identified after a comprehensive literature review. Second, after discussion with experts, the barriers were classified into 23 pre- and 21 post-adoption barriers. Next, the barriers were ranked based on 218 completed survey responses from professionals working in 125 organizations in the Indian construction industry. Finally, an independent samples t-test was conducted to understand differences in the perceptions of different groups of participants. The top five pre-adoption barriers were (1) high hardware costs, (2) high software costs, (3) low adoption across the supply chain, (4) low market support, and (5) unclear benefit evaluation. In comparison, the top five post-adoption barriers were (1) high ongoing cost (license renewal, training cost, etc.), (2) shortage of skills and expertise, (3) unclear benefit evaluation, (4) client's lack of understanding, and (5) user resistance. Moreover, clients, contractors and consultants shared different views on very few barriers, which shows that these barriers are prevalent across different types of organizations in the Indian construction industry.
