INTEGRATION OF GIS AND BIM TECHNIQUES IN CONSTRUCTION PROJECT MANAGEMENT - A REVIEW

Construction industry has become much more complex due to the large number of people and documentations involved. As a result, the full process of building construction may involve with many different types and format of information that needs to collect, document and share. In order to share this information between architect, contractor, construction manager, etc., there are need to develop a common model that can document and store this information in single platform. BIM represents a series of parametric objects that composed together to form a building model which carries all information includes their physical and functional characteristics and project life cycle information. Since BIM represent the detailed geometrical and semantic information of the building, the application of GIS is needed to manage the construction project's information resources. GIS can use information from many different sources, in many different formats and can link data sets together by common locational data such as coordinate or postal zip code. Besides, GIS can use combinations of data sets to build and analyze integrated information and also can convert the existing digital information into a form that meets the user's need. From this point of view, GIS can complement BIM function in order to develop a systematic platform for construction purpose. Finding of this study, there are some drawbacks in this technique especially in the construction application in term of data sharing, data integration and data management. Furthermore, the integration of GIS in BIM is studied and potential techniques are shown to overcome the drawbacks of the construction application.
