Trimble's machine control systems and two-way data communications technology are being used for the construction of the New Perth Bunbury Highway -- the single largest road project ever undertaken in Western Australia.

When completed, the new 70-kilometer (43.5 mile) section of New Perth Bunbury highway will provide motorists with a continuous dual carriageway from Western Australia's capital city Perth to the state's major commercial centers and tourist destinations in the South West. The project is expected to be constructed over three years and will include the placement of approximately nine million cubic meters (9.8 million cubic yards) of soil to raise the road alignment above low lying areas subject to seasonal inundation.

Responsibility for the highway's design and construction lies with the Southern Gateway Alliance (SGA). According to Tony Cariss, construction coordination manager for the SGA, seasonal conditions, the scale of the work, and the relatively short lead-time means that construction needs to follow extremely close behind the design work.

"Trimble technology has offered us precisely the solution we needed to fast track the project," said Cariss. "We needed accurate machine positioning for construction purposes and an instant two-way data transfer between the field and design office."

Haefeli-Lysnar, Trimble's distributor in Western Australia, met the alliance's requirements with a Trimble Connected Site solution that includes a unique combination of Trimble machine control systems and a Trimble wireless communications network that represents an innovative application of the technology.
