Abstract
Abstract. Computer-aided collaborative and multi-scale 3D planning are challenges for complex railway and subway track infrastructure projects in the built environment. Many legal, economic, environmental, and structural requirements have to be taken into account. The stringent use of 3D models in the different phases of the planning process facilitates communication and collaboration between the stake holders such as civil engineers, geological engineers, and decision makers. This paper presents concepts, developments, and experiences gained by an interdisciplinary research group coming from civil engineering informatics and geo-informatics banding together skills of both, the Building Information Modeling and the 3D GIS world. New approaches including the development of a collaborative platform and 3D multi-scale modelling are proposed for collaborative planning and simulation to improve the digital 3D planning of subway tracks and other infrastructures. Experiences during this research and lessons learned are presented as well as an outlook on future research focusing on Building Information Modeling and 3D GIS applications for cities of the future.
Highlights
Though Computer Supported Collaborative Work (CSCW) and research of CSCW environments have a more than 10 years history in computer science (European Commission, 2006), in Building Information Modeling (BIM) and Geographic Information System (GIS) practice, the support of collaborative work and planning are still at its beginning
In 3D city models and the data standard CityGML - defined by the Open Geospatial Consortium (OGC) - scale is defined by five level of details (LoDs)
This paper has provided new research on the deployment of 3D city and infrastructure models by integrating approaches from civil engineering computing and geoinformatics such as collaborative work, multi-scale modelling, and computer vision
Summary
Though Computer Supported Collaborative Work (CSCW) and research of CSCW environments have a more than 10 years history in computer science (European Commission, 2006), in Building Information Modeling (BIM) and Geographic Information System (GIS) practice, the support of collaborative work and planning are still at its beginning. This can be justified by the complex processes of city planning and by the complexity of 3D modeling.
