  The concepts of Building Information Modelling (BIM) and sustainability are relatively new concepts in the Architectural, Engineering, and Construction (AEC) industry. This paper aims to investigate the perceived benefits of integrating BIM and sustainable practices in construction projects. A quantitative approach was adopted, and data were collected from fourteen invited experts from both the academia and industry via a two-round Delphi survey. The data were analyzed to establish the ranking of each factor, and the Kendall’s concordance test was used to determine the level of consensus among the respondents in each round. Most of the perceived benefits were ranked significant and important. More so, of the 36 beneficial factors, four factors were rated as highly important which are related to effective sharing and exchange of project data, better design of products, accurate geometrical representations of building models with embedded sustainability data, and ease of simulating building performance and energy usage. With these key benefits in mind and collaborative working in the AEC industry, the concepts and ideas of a sustainable urban city can be achieved in the built environment.
