12d and TMR Light Up

Sudharsanan Loganathan of the Department of Transport and Main Roads, Queensland (TMR) spoke to our Technical Forum audience about a lighting module in 12d Model he’s been working on. It includes some tools to help designers produce models, and specifically to create consistency in processes and improve the as-constructed.


Managing assets was vital to his team – they’re now doing more with what they’re given. They focussed on improving processes and efficiency. Implementing BIM has been very important. The lighting package is an R&D project to improve these processes.

Lighting was chosen as a test case because it leads to significant benefits – it’s still in the 2D drafting stage, so making it 3D helped a lot. It was also low risk in terms of dollar values – it’s easier to shift lighting than, say, a bridge! Points and linear assets are dealt with at the same time.

It was a big change for their electrical designers to come back to a modelling space. With road operations moving more and more into this space – self driving vehicles, etc. – they need their information and assets all in right spot; there’s no room for errors/omissions.


The main objective was to clarify the handover requirements from the TMR side – they need to build something, but what does the client actually want, in detail?

Other benefits included:

  • Minimising hard copy drawing requirements at handover
  • Minimising manual processes
  • Minimising duplication
  • Improving information management
  • Providing data validation
  • Improving quality and consistency of ‘As-Built’ information.

Project Life Cycle

  • Planning – single source required
  • Design
  • Construction
  • Finalisation
  • Asset Management (also archiving, etc.)

Components of the Lighting Module

  • Lighting Schema
  • User interface to help create a valid data file (xml format)
  • Data validation
  • Design tools: modelling lighting installations in 12d Model, performing electrical calculations, generating electrical schematics, generating tables/schedules.

What’s Next?

  • Finalising attributes required for construction and finalisation stages
  • Expanding the schema to cater for all other ITS&E assets
  • Creating tools to bring the ‘BIM model’ out into the field
  • Linking/integrating with their DMS
  • Migration/Integration with Industry Foundation Classes (IFCs) 5.0.
