 Building Information Modeling (BIM) is a process concerning the formation of digital representations of the physical and functional features of built spaces. A significant increase of the BIM utilization in the Architecture, Engineering, and Construction (AEC) sector are becoming more accessible and functional. The BIM methodology was developed in order to provide an effective system for building management as well as to organize the collaboration between different parties. Industry Foundation Classes (IFC) is maintained by buildingSMART; enable an interoperable format for exchanging BIM data between different software platform which is capable of restoring both geometric information and rich semantic information of building components to support lifecycle data sharing. BIM provides a detailed 3D geometrical model with rich semantic data. In contrast, Geography Information Science (GIS) offers powerful spatial analytical tools. As the benefits brought by the integration of Building Information Modelling (BIM) and Geographic Information Systems (GIS) are being proved by many researchers, further spatial analysis can be applied that can benefit indoor-outdoor integrated applications. Recent research has mainly discussed the process required for data conversion from BIM to GIS. Thus, more specifics requirements on the functionalities of a 3D indoor applications need to be considered. In this study, the use of BIM IFC for 3D indoor GIS was reviewed, especially on the data conversation, data management, and 3D spatial analysis. The aim of this paper is to reveal the 3D indoor GIS requirements for space management. Therefore, the requirements were analyzed in four aspects: 1) data level integration; 2) data management; 3) 3D indoor GIS analysis; and 4) 3D space management. 3D space management was developed according to the requirement. Future research will be testing the conversion data in a GIS environment, the data structure for the 3D indoor GIS will be designed and a prototype will be developed to demonstrate the spatial analysis functionalities for 3D space management. © Published under licence by IOP Publishing Ltd.
