Building Information Modeling (BIM) is the process of generating and managing data of built facilities and assets during their life cycle. By using BIM models in the initial design and implementation phases of assets, and transferring the information to the next phases of the life cycle, the total costs of Asset management in its maintenance and operation phases can be reduced. BIM technology providers are Autodesk, Bentley Systems, Graphisoft and others.
Geographic Information System (GIS) is a system that captures, stores, analyzes, manages, and presents data linked to at least one geographical location. GIS can function as a decision support system, assist in the solving of real-world problems in various fields such as urban planning, geology, hydrology, surveying and mapping, land and resource management, market analysis and others. GIS software packages are available in both commercial (e.g., ESRI’s ArcMap Desktop and Server versions, Intergraph, and Autodesk, Obsurv) and open source (e.g., GRASS, QGIS, MapWindow) products. GIS is interoperable with other systems, being able to read and write to CAD, JPEG, TIFF, ASCHII, GML, KML, PDF and others.
For better management and improved performance of public assets, it is imperative to include GIS with BIM. This should lead to more sustainable construction projects, faster project deliveries and greater design accountability. The BIM - GIS integration is about cooperation between parties involved in different stages of asset life cycle.
It is thus important that the information transfer and communication between parties is as clear as possible. This can be realized by implementing BIM in AM from an asset’s initial (concept/design) stages, and integrating it with other systems used in AM processes, such as GIS.
