Developed and promoted by Architecture, Engineering and Construction (AEC) industry, Building Information Models (BIM) provides the most detailed 3D spatial and semantic information about every building element during the lifecycle of a building. BIM is a 3D digital data space for sharing building information to enable multi-disciplinary collaboration among different actors involved in the development process of buildings. Recent surveys indicate that the BIM-based paradigm brings more productivity gains and long-term benefits.
Therefore, this working group aims to promote BIM in IAG and encourage and report innovation in integrating BIM with geospatial engineering. This working group will conduct its activities in close collaborations with other relevant international professional organizations, such as GSDI, ISPRS and FIG.
Major objectives of this working group are to study, and report the use of:
- To promote BIM and raise awareness in geospatial engineering applications
- Integrating 3D mapping technologies and BIM
- Interoperability between and other geospatial formats
- Applications of BIM in indoor navigation, indoor positioning, 3D cadastres
The objectives of this working group in the next three years are to:
1. Develop an adaptive geospatial engineering specific BIM curriculum
Building Information Modelling (BIM) and digital engineering have begun to shift the way the architecture, engineering and construction industry operates. The geospatial professionals have the opportunity to take a more prominent position in this paradigm shift. The shift is expected to take place exponentially soon. The silo-based engineering approaches will no longer address the needs of this shift. Instead, the need for competencies in collaboration and digital principles are becoming more prominent. This need will make the data management and sharing skills of geospatial professionals critical for the future of engineering. This working item provides a review of the contemporary AEC challenges and recommends an approach to a geospatial specific BIM curriculum design.
2. Highlight disruptive GeoBIM for construction
The productivity and efficiency of the construction sector have been long criticised. Large construction projects typically take 20 per cent longer to finish than scheduled and are up to 80 per cent over budget. Geospatial challenges have been identified as a significant reason that projects are delayed and go over budget. This working item focuses on disruptive geospatial solutions such as LiDAR, UAV-based mapping, GPR, tracking in GPS denied environments that can be integrated into BIM to support stages of a construction project including brief, concept, definition, design, build and commission, hand over as well as operation and maintenance.
