From BIM to Industry 4.0—Egis BIM Strategy for Metro: Systemic, Parametric, Interoperable
Major urban transport projects are an opportunity to develop BIM and PLM applied to railway systems and underground structures. This involves extending BIM processes to linear infrastructures, transport system operating equipment and their environment for design, and implementation and asset management. Methods based on the automation of model generation and model views (2D, 3D, GIS) from object databases and libraries make it easier to integrate information from designers, manufacturers and contractors. The construction of complete digital mock-up makes it easier to control railway projects, characterized by the high reliability, operability, and safety requirements, strong maintenance constraints, but also by the complexity of the interfaces, the geographic extent and the long infrastructure lifecycle. We will show you how Autodesk tools made it possible to take a step towards the open BIM on the Grand Paris Express automatic metro project and Lyon – Line E project. Our demonstration will deal with the topics of: 1) ensuring that the project data is of high quality through BIM model structuring, library of standard objects, standardization of property set; 2) saving time from design to shop-drawing and from construction to O&M by ensuring the digital continuity by using open format (IFC) and open data dictionary (bsDD = buildingSmart International) over the lifecycle of the project; 3) encouraging and improving collaboration among multidisciplinary teams by robust and smooth processes by using BIM Collaboration Format (BCF) Manager and GIS; 4) managing the infra-systems interface in linear infrastructure and station buildings; 5) automation of metro station modeling through Dynamo by a functional approach; 6) automation of linear infrastructures and systems modeling through Dynamo using object database; 7) extension of modeling to the geology.

The Virtual Mockup: Parametric Design and Optimisation of Complex Faヘade Panels in Virtual Reality
Nowadays available parametric modelling techniques allow for easy generation of geometrically complex faヘade elements. Evaluation of aesthetical quality of created design variants is often performed using 2D representations whereas physical 3D models are costly. Combining parametric design with design visualisation in virtual reality (VR) allows for aesthetical evaluation, review, design, and optimisation of unlimited alternatives on a full scale without the need for physical mock-ups. Speeding up design process and lowering potentially costs for mock-ups. This combination of virtual reality and parametric modelling has been applied in the design of the eye-catching faヘade for the new Naturalis Biodiversity Center in Leiden, The Netherlands, in 3 alternative workflows. One part of the facade consists of 'bone'-shaped elements. Their complex 3D geometry was generated using a Grasshopper model. This parametric model was live connected to a VR model of Revit through an automatic cloud connection using Flux.io, Dynamo and Enscape. Design modifications in Grasshopper were synchronised within seconds to the VR world. This allowed the design team to assess dozens of variants per hour to optimise the faヘade for transportability of elements while remaining aesthetical pleasant. Combining parametric design with VR allows for quick iteration of design variants while experiencing the performance and aesthetics of the design, not limited to a fragment but for the complete building. This increases the speed of design iterations which may increases efficiency or may allow for a more sophisticated design. Potentially, a costs and time reduction for physical models can be realised. Although physical models will still require for the 'feeling of the design' and as a test of the production process, now the most likely variant can be selected for the mock-up.
