Macro Development - Gold Coast Rapid Transit
Project Summary
A number of new macros to help to efficiently and accurately model the Gold
Coast Rapid Transit light rail design using 12d Model software.
The Challenge
The Gold Coast Rapid Transit consists of 13km of dual track light rail system
in a shared Road and Rail corridor, connecting the Griffith University to
Broadbeach.
Technically challenging, the light rail system occupies much of the existing
road corridor requiring alterations to the functionality of the road network.
This design requires very close coordination between the rail and road
alignments to ensure an integrated approach. As part of a multi discipline
design team, Arup has also delivered the designs for four bridges, numerous
retaining walls, track form, stormwater drainage, system conduits and pits,
lighting, traffic signals and more.
It was decided to deliver the detailed design as a fully integrated 12d
project, with 12d Model design teams including rail, road, stormwater drainage,
survey (by Others) and utility services (by Others).
Before commencing rail
design, the team worked with 12d Solutions to identify the unique modelling
requirements of a light rail system. With the help of the 12d Support team, the
functionality needs and existing tools available to complete the work using 12d
software were investigated, and a number of potential tools identified to help
the team efficiently and accurately deliver the project. The particular issues
identified were the application of cant to not just the rails but also the
surrounding trackslab, kerbs, etc., and also checking and presenting stopping
sight distance requirements particular to light rail design.
The Solution
The solution was a number of new macros to help to efficiently and accurately
model the light rail design using 12d software.
The Result
The 12d Model macros helped the team to efficiently and accurately model the
light rail design.
