TPF Ingeniería | Efficiency Underground: Málaga Metro's BIM and IFC 4x3 Integration

lim.wendy — Fri, 22 Sep 2023 03:40:59 GMT

The extension of line 2 in the Málaga Metro project was done using the Building Information Modeling (BIM) methodology, considering the complexities of construction in an established urban area. Significant efforts were invested in various tasks, including the creation of a 3D model for a cut and cover tunnel with slurry walls, coordination of different disciplines using Navisworks, and conducting 5D budget analysis.

Those attending the event will witness a real-life example of a civil infrastructure project that employed Autodesk software. Numerous challenges were encountered during the project's design phase. Specifically, the utilization of specialized tools in Civil 3D to calculate lofted volumes and the adoption of parametric modeling tools for water supply networks, sanitation, and electricity were crucial in developing the models. Furthermore, noteworthy advancements were made in the IFC exportation processes by Autodesk for the IFC 4X3 version. The presentation will showcase multiple models to illustrate these concepts.

Hey, thanks for the presentation. I see you worked in Civil 3D, may I ask: Are the sleepers a reference of one object or each a unique defined geometry? If they are placed as references, how did you manage to do that in C3D?

Hi there, @rosa.urenaJTRL3, thank you again for your informative presentation! It's great to see your expertise in Civil 3D.

@kevin_schmidt, that's a fantastic question regarding the sleepers in Civil 3D. I'm sure @rosa.urenaJTRL3 can provide some insights into this.

Rosa, the user is interested in whether the sleepers in your presentation are treated as references or unique defined geometries in Civil 3D. Additionally, if they are placed as references, they are curious about the method you used to achieve this in Civil 3D.

Your response would be greatly appreciated to shed some light on this aspect of your presentation. Thanks in advance!

Hi @kevin_schmidt,

Sadly, I do not know exactly how @rosa.urenaJTRL3 did this on the project. But from what i can see on the slides, I would expect that this is automated 3D Block placement. The contained geometry is supported by the IFC 4.3 exporter so that would assure their workflow. This automated placing can be achieved through the use of Dynamo in Civil 3D. using the alignment, profile geometry and the cant values exact placement can be calculated. If needed, we can certainly help u look further in the right direction.

so the geometry in the ifc4x3 is only defined once and then just referenced for the other positions?

Hi @kevin_schmidt,

While I am not the biggest authority on IFC, if i remember correctly IFC does not have an instancing definition. So, the geometry of every object is included. Making it a complete, but heavy exchange format. If you define the right meta data on the objects, you might be able to identify and process instances differently. But other IFC viewer will not process the files in the same way. (@heidi_castellanos_leyra, can you confirm or add?)

Thats one of the big changes that IFC4x3 is supposed to bring. References along an alignment should be possible as far as I know. I just don't know how to do that in C3D, thats why I asked my initial question.

Hi @kevin_schmidt, @wouter.bulens72EDZ ,

Indeed, IFC will exchange the geometry of each sleeper or any other rail object, with the metadata included, if you map it to the good class 🙂

Its each object geometry that's being exchanged, you can add the technical reference for the sleepers in the ¨Pset_TrackElementTypeSleeper" if you need to make reference to a national standard, reference geometry.

Hope it helps
