Abstract
Abstract. Building Information Modelling is a new technology and tool for researchers in Architecture/Construction/Engineering (ACE) fields, and it is designed to organise the collaboration between different parties and manage all types of information regarding buildings. A standardized data model of BIM named Industry Foundation Classes (IFC) has been proposed to describe building & construction related information and facilitate the interoperability of building data. As IFC contains plenty of building information, further spatial analysis can be applied in geographical information system (GIS) with these information. Current research has mainly discussed the requirements about data translation from BIM to GIS. However, more specific requirements on the functionalities of a generic 3D indoor framework need to be considered with IFC data. Although this research is in the initial stage, we investigate the use of BIM IFC for the 3D indoor framework, especially on the data translation from IFC to the framework, data management in the framework and IFC data for 3D spatial analysis. Requirements are analysed in four aspects: 1) automation of indoor vector map generation; 2) data management for the framework; 3) environmental analysis of the framework; and 4) safety analysis of the framework. According to these requirements, new modules need to be developed. In the future, based on IFC data we will conduct tests of data transformation, design a data model for the 3D indoor framework and develop a prototype to demonstrate the planned spatial analysis functionalities.
Highlights
Building information modeling (BIM) is an active new technology and tool in Architecture/Construction/Engineering (ACE) fields, and it is designed to organise the collaboration between different parties and manage all types of building information
We argue that the research focus regarding BIM to geographical information system (GIS) can be shifted to more practical topics, i.e., to develop and optimise more spatial analysis functionalities which can facilitate the use of BIM information
As BIM is adopted for information modelling for researchers in AEC fields, it concentrates on the accurate descriptions on building system, elements and accessories
Summary
Building information modeling (BIM) is an active new technology and tool in Architecture/Construction/Engineering (ACE) fields, and it is designed to organise the collaboration between different parties and manage all types of building information. Considering the translation from the IFC data model to a new designed data model for indoor navigation, Isikdag et al (Isikdag et al, 2013) propose related conceptual requirements on a building model These requirements aim to preserve semantic information and properties of building, real 3D structural information (e.g., vertical levels), spatial relationships of building elements and their interoperable geometry. In this example, the authors focus on the necessary portion of IFC data to. This research is in the initial stage, this paper aims to reveal the requirements about the 3D indoor framework This framework is designed to incorporate 3D indoor modelling with spatial analysis.
