Gold Coast Light Rail – Stage 2

Project Description

In 2016 GoldLinQ announced that CPB Contractors were the preferred design and construction partner for the Gold Coast Light Rail – Stage 2. This stage is 7.3 kilometres long, is dual track and connects the heavy rail at Helensvale to the Stage 1 Light Rail at the Gold Coast University Hospital. The project is estimated to cost about $420 million and was operational for the Commonwealth Games in 2018.

In early 2017, Meadows Consulting P/L was asked to provide survey support to Martinus Rail P/L during the track construction phase. Martinus Rail P/L were engaged by CPB Contractors specifically for the track construction discipline of the project and have been ably supported by us, with track being constructed to tight tolerances.

The 7.3km route consists of ballasted track, embedded track and track slab. The project involved two road and rail interfaces at Napper Road and Olsen Avenue. The project was successfully completed in late 2017.

From all reports the project has been a runaway success and it will provide the area with an efficient, convenient, well patronised public transport system that will service this area of the Gold Coast.

Tootool bridge

Tootool Underbridge Renewal

Project Description
The underbridge at Bullenbung Creek, within the township of Tootool, lies on the Boree Creek Branch Line about 563 kilometres south west of Sydney.

This underbridge consisted of 40 timber trestles all of which were slowly deteriorating and in need of replacement.

We carried out a very detailed survey of the underbridge as well as of the topography, creek and existing track.

The engagement also involved the re-design of the horizontal and vertical alignment, which was required to commence the gradual trestle replacement program.

We eventually replaced the bridge in 2011 (for Rhomberg Rail Australia) using a series of pre-cast concrete culverts.

Goodwood Junction Grade Separation

Project Description    

  • Brand new dual track in slab on the Seaford line – approximately 300m in length x 2 tracks
  • Permanent Survey control was supplied by the client.
  • New technology known as the Rhotas G5 system was utilised to adjust / fine tune the track position, level, gauge and super elevation.
  • This system utilised a digital gauge bar (known as the ‘digi-bar’) and remote connectivity with a Leica total station. This resulted in instantaneous answers measuring gauge, lift, line and super-elevation. Therefore adjustments to the track could be made in real time and subsequently checked in real time.

Challenges & Outcomes

  • This projected presented a steep learning curve in the development and use of this specialised digi-bar technology.
  • The project was successfully completed on time.
