The recent initiatives of the construction industry to embed sustainable strategies in its processes can be enhanced when clear and practical benefits of such integration are available to project stakeholders to support their decision-making. Hence, this study purports to evaluate the perceived benefits of integrating BIM initiatives and sustainability practices in construction projects. Delphi survey technique was used to solicit the perceptions of expert panel on the 36 identified benefits. Statistical tools were employed to analyze the derived data, and the consensus reached by the expert panel was validated using the interrater agreement statistics. The three most important benefits included the ability to enhance overall project quality and efficiency and improve the ability to simulate building performances and energy usage and facilitate better design products and multi-design alternatives. Comparative analyses among the expert groups lend credence to the strong consensus reached by the expert panel. Meanwhile, the study recommended strategies to enable the construction industry to key-in to these benefits as well as identifying prevalent research gaps in practice. The studyös findings will enhance the drive for the realization of the sustainable smart city as well as equip various stakeholders of the possibilities in its full adoption and implementation.
