More systems for cable management
So maybe that's kind of a translation problem. But since the other cable guarding, fixation or management options don't exist I'll give it a try.
First of all, there's this text in combination with a picture:
The picture tells me that this is a flexible conduit. While the text tells me that it's a rigid conduit (it's apparently rigid with 90°-bows). The only other type of cable management is the cable tray. Sadly, I can't tell what solutions other nations outside Germany use. But since there're a lot more options in real life I'll just write a list and name some companies with examples (just examples other companies surely are also good / no marketing).
- flexible conduit: it's normally used for fast installation, the conduit is laid inside concrete and connected with mounting parts (see the ribbon "strucutural reinforcement" under structural engineering), it can also be laid inside dirt or underneath the floor above the raw floor
- companies: fraenkische for flexible conduits (diameters from 16-150mm) inside concrete or underground: https://www.fraenkische.com/en/application/installations-concrete-commercial-buildings ; kaiser-elektro for mounting parts: https://www.kaiser-elektro.de/en_DE/products/electrical-installation/concrete-constructions/
- device installation channel: installed on a wall and equipped with sockets it's fast and easy to manage your cables
- underfloor applications: installed on the raw floor, used for electrical tanks with sockets
- rigid conduit (better translated as "Installationsrohr") - this exists
- cable tray - this also exists
With underfloor applications and device installation channel it's also possible to find alternatives - as the mentioned companies already offer rfa-files for these product lines with some more or less comfortable workarounds. Some also don't need coordination between other parties, so that it's mostly acceptable to not draw cables. But if the cable weights 10kg per meter and needs to be layed in radius of 70cm, you might also draw the cable - just for making sure that everything works as planned. The flexible conduit might act similar to the flex ducts, today a solution with Autocad splines is much faster and looks better than with rigid conduit from Revit. The company "fraenkische" created a revenue of 575 million euro mostly with flexible conduit. So these products are used in reality, but can't be used or replicated with similar things inside Revit. This way some things are still missing for a whole BIM process.
It might not be easy, but supporting flex conduit is really needed. The precast concrete is sometimes delivered from diffrent contractors and it's often really hard to describe with 2D-drawings what needs to be build and where the failure happened - not to mention the ways to fix occuring problems.
