Today, construction is essential to every economy since it employs many workers and significantly contributes to GDP. The construction industry’s efficiency has lagged behind other industries for decades due to low productivity, a lack of research, and poor adoption of advancements. Fortunately, the successful development of digital technologies such as Digital Twin (DT) has facilitated growth in many sectors, and DT has the potential to address challenges in building construction projects. While DT is a virtual replica that provides real-time data and analysis of a physical asset to optimize its performance, Building Information Modeling (BIM) is a collaborative process for creating, managing, and exchanging information throughout a construction project. BIM is the most efficient way to create an accurate, high-value DT and support industry transformation. An integrated DT and BIM platform can improve building design, construction, and performance in the architecture, engineering, and construction (AEC) sectors. Based on a literature review, this research aims to clarify and differentiate DT from other advanced 3D modeling technologies, such as BIM. Related publications from articles about DT and BIM in the construction industry were selected, identified, and organized after careful research of the relevant scientific databases. The research has three primary objectives: (1) to examine the present applications of DT and BIM in the construction industry; (2) to emphasize the similarities and differences between the two; and (3) to develop solutions and design methods for BIM and DT integration in building construction.
