Arup and PB design Australia's largest road project

Parsons Brinckerhoff (PB) and Arup are in the detailed design phase for Australia’s largest ever road infrastructure project, serving Brisbane Airport in Queensland.

PB and Arup joined forces as the PBA JV to provide services, including early and ongoing design, for the Airport Link, Northern Busway and Airport Roundabout. Airport link will be toll road mainly housed in tunnels to bypass and relieve congestion on the surface.

Within tight deadlines the PBA JV joint venture team of 250 designers must deliver 500 design packages for Thiess John Holland throughout the construction of the project.

Arup's Australasian infrastructure leader Frank Vromans said it was a fantastic opportunity for the two infrastructure and planning companies to join forces.

“This project is so significant and the detailed design needs so complex that it requires a multi-disciplined team to ensure we get it right."

PBA project director Luke van Heuzen said Arup and PB are jointly providing design services in relation to structure, geotechnics, tunnelling, traffic, water, environment, fire, urban design and acoustics.

“We are currently in the detailed design phase which means the team is fleshing out the exact specifications from the concept design. They see this work as their opportunity to make a difference to the future of Brisbane.

“PBA JV’s international tunnelling expertise is proving invaluable in the design of the two tunnels in the project,” said Mr van Huezen.

The PBA JV innovative design elements include:
• relocating Airport Link underground to minimise construction impacts on surface roads;
• improving traffic capacity with an underground busway station and road bridges;
• providing pedestrian and cycle access;
• partially burying two of Airport Link’s three ventilation stations.

Preliminary construction works have already started in order to provide alternative pedestrian and cycle routes before significant construction begins.

All three projects are expected to be completed by mid 2012.
