BIM allows engineers and contractors to leverage existing GIS information, explore innovative designs and to test alternatives and simulate real-world performance, developing a better understanding of various stages of the project, all while keeping a geospatial context. Urban utility infrastructure, retrofitting and replacement involves a mix of engineering design and geospatial activities that involve short, medium and long duration transactions and that support the planning-design-construction and operations cycle both above and below the ground.

The integration of building information modeling (BIM) and geographic information system (GIS) in construction management is a new and fast developing trend in recent years, from research to industrial practice. BIM has advantages on rich geometric and semantic information through the building life cycle, while GIS is a broad field covering geovisualization-based decision making and geospatial modeling. . BIM-GIS integration is to integrate the strong parts of both BIM and GIS for building and city modeling.

Applications BIM-GIS integration reveals that current applications have three primary advantages. First, data and information with multiple spatial scales are integrated to address the problems related to both construction components and built environment even urban environment. This is also a starting point of using BIM-GIS integration. Second, the primary function of BIM has been applied that provides complete and detailed geometry and material information of building components. Finally, visualization-based analysis improves the efficiency and performance of construction management in AEC projects.
