A Review of Recent Researches on Integration of Building Information Modeling (BIM) and GIS

Today, building information modeling (BIM) technology has become an important and practical platform for achieving the goals of smart cities. However, this technology considers buildings alone and without regard to their exterior space and other buildings in the city and also lacks the necessary tools to perform various spatial analysis. In this regard, the intrinsic sharing between BIM and GIS shows that integrating them can provide proper knowledge in various urban applications in both indoor and outdoor. Although BIM and GIS are designed to achieve separate goals, they both manage 3D modeling information. BIM providing and displaying micro-level information about building and interior space, as a rich source of building information. GIS often provides and displays macro-level information in the exterior of the building as environmental information and has suitable spatial tools. In general, the integration of BIM and GIS enables better management of spatial information and better decision-making to solve issues related to different urban applications that have been studied extensively in recent years. This paper, while reviewing BIM technology and information exchange standards in BIM and GIS, reviews some research on the integration of BIM and GIS from 2008 to 2020. This paper attempts to provide researchers with a general classification of previous studies in this specific field by classifying the methods and extracting the application areas of BIM and GIS integration.
