Design and documentation of 13km of sealed access road to serve BHPBP’s Macedon Domestic Gas Plant and Chevron’s Wheatstone LNG Plant near Onslow, WA. It was designed to full state road specifications to allow for future takeover by Main Roads WA.

The road traverses the floodplain of the Ashburton River, requiring complex 2D hydraulic modelling, numerous floodways and a 120m-long bridge over the Quick Mud Creek breakout.
