Gold Coast Rapid Transit

A new 12km light rail system connecting the University Hospital at Parklands Drive to Broadbeach, passing through Surfers Paradise and crossing Smith Street and the Nerang River on major bridge structures. The proposed works involved the construction of an in-ground slab track design for the majority of the alignment, overhead power supply and suitable signalling systems. The design also included a rail maintenance facility and tram storage depot. The relocation of Public Utility Plants was a major consideration as was the constructability and scheduling of the works.

Our involvement

Aquenta was initially engaged by GHD to develop robust cost estimates for the comparison between a Rapid Transit Tram system and a Busway System. Taking the preferred Rapid Tram design solution forward, the cost estimates were then refined using a higher level of design maturity. Given the high risk to many elements of the project, Aquenta also performed risk assessments for the planned risk elements and took part in risk workshops to assess a suitable project contingency.

Subsequently, various other commissions were added to Aquenta’s initial scope of work including, undertaking cost comparison exercises and developing estimates for key elements of the project, namely the Smith Street Bridge and the Olsen Avenue underground station at the University Hospital.

Aquenta also undertook a commercial Due Diligence role for one of the PPP consortia, teaming up with Atkins Global who performed the Technical Due Diligence role for the proposed submission.

The outcome

Our initial cost estimates formed part of the overall project feasibility packages that were forwarded to the appropriate state finance departments. The project then progressed to tender for interested consortia. The consortium that Aquenta/Atkins was involved with won the tender and the Gold Coast Rapid Transit project is currently under construction.
