SH18 Hobsonville Deviation
In undertaking the tender of the $200 million Hobsonville Deviation project in
Auckland, New Zealand, Aurecon’s goal was to deliver an innovative design at
a competitive price and enable HEB Construction and Aurecon to continue with
detailed design of the road project. Using MXROAD, Aurecon was able to create
a model easily adaptable to design changes.
Aurecon reduced the time needed to generate new volumes when design
modifications were required to two hours from the typical one to two weeks.
This allowed Aurecon to test multiple alignments in rapid succession and
quickly take on the contractor’s board-revised geotechnical constraints and
operational demands. Through this iterative process of alternate scenario
studies, the total earthwork cut for the project was reduced from 1.5 million
cubic meters to 1.2 million cubic meters.

Traffic on South Road, the strategic north-south arterial route for moving freight
within metropolitan Adelaide, Australia, is predicted to increase 6 percent
each year through 2020. To accommodate the increase, the South Australian
government plans to transform South Road into a 22-kilometer nonstop route
between the Southern Expressway and the Port River Expressway.
The major challenge facing the design team was maintaining two lanes of open
traffic at all times. MXROAD was essential in developing traffic plans and
diversion routes, and MXROAD easily accommodated the evaluation of multiple
scenarios, assuring the development of the most cost-effective design and
safest construction possible. The quick evaluation of multiple scenarios also
reduced disruptions impacting local businesses.
