The link between the real and the digital world.
RSRG's "BIM reality capture" team provides support in planning, construction and asset management.
Building Information Modelling (BIM) is a discipline which, after years of successful use in building engineering, now also has a role in the transport infrastructure sector. This discipline includes all types of surveying methods, in particular those capturing millions of individual points of the real world. Which gives us the new term of Reality Capture (RC). “With it, we describe a circuit between the real and the digital world, from capture, via processing, production of a digital image, planning, modelling and setting-out and back to capture,” explains Helge Grafinger, Project Manager R&D Reality Capture Projects at RSRG.
The new RC team at Rhomberg Sersa Rail Group covers all these aspects. Grafinger: “Our aim is ease of use of digital models on the construction site, so that all project participants receive the correct information about which part is to be built when and how. Subsequently, when the final infrastructure is in operation, all parts will be available in digital form, together with their history and their performance.”
As RSRG covers the different stages of the digital infrastructure and standards of BIM use by infrastructure owners around the globe, the BIM RC team uses a number of technologies to meet their colleagues on site at the right level of application. The range starts with user-friendly GNSS devices with PDF 2D drawings and ends with fully model-based machine control systems. Likewise, specialists use all types of laser scanning systems and photogrammetry on the basis of drone images. All point clouds in true colour are furthermore converted into usable data structures which can be used on computer screens or smartphones via the internet.
