Cloud-based BIM data transmission: Current status and challenges

Abstract

In the architecture, engineering and construction (AEC) industry model-based data exchange methods are mainly based on manual file transfer, data conversion, and data-merge. File-based Building Information Model (BIM) data exchange is either in vendor specific file formats or neutral format using Industry Foundation Classes (IFC). IFC Model View Definitions (MVDs) proposed by the US National BIM Standard can assist cross-platform BIM data exchange. Since BIM applications are steadily moving to the Cloud, the study of Cloud-based BIM data transmission techniques become significant. The main objective of this paper is to investigate how building data transmission can be managed in current Cloud-BIM applications and what challenges exist in the current systems. Therefore, in this study, methodologies for Cloud-BIM data integration are investigated. Features of each technique is specified. The strengths and weaknesses of current systems are indicated with regard to data transmission requirements for Cloud-based BIM applications. In addition, the study investigates the challenges to cross-platform BIM data transfer in making multiple Cloud-BIM applications interoperate. The challenges in current data transmission approaches highlight the need for an effective network-based BIM data exchange to address a collaborative BIM work flow in the Cloud.
