Development of an IFC-Based Converter for BIM Integration into Augmented Reality Applications for Building Construction Trades

Abstract: To address the shortage of skilled labor in the construction industry, the application of augmented reality on construction sites offers substantial potential to enhance coordination and communication among different trades, thereby reducing labor-intensive processes. This requires the reliable transfer of geometric and semantic information from Building Information Models, including all data relevant to construction execution, through suitable data exchange formats. This paper defines information requirements for the IFC schema for the BIM-to-field use case in the construction trades, discusses appropriate exchange formats for geometric and semantic data, and presents the development of an IFC-to-Unity converter.
