© 2018 Elsevier Ltd The built environment faces numerous challenges in its quest to be more productive and sustainable, and to the adoption of a smart and creative process of carrying out the various operations. This study aims to investigate the profound barriers faced by construction stakeholders in their attempts to integrate BIM and sustainability practices in the construction processes. A two-round Delphi survey formed the basis of aggregating consensus among the expert panel based on a set of 38 factors derived via content analysis of previous research studies. Descriptive and inferential tests were employed for data analysis, and the results validated using the interrater agreement analysis. The three key barriers by descending order of significance are industry's resistance to change from traditional working practices, an extended period of adapting to innovative technologies and the lack of understanding of the processes and workflows required for BIM and sustainability. Deductions were also made based on the comparative analysis of the expert groups. The findings will advance the implementation of BIM and sustainability practices in construction projects and enable project stakeholders to focus on addressing the critical challenges discussed in this study.
