Last night, PSM Principal Strath Clarke gave an engaging technical presentation at the AGS Seminar in Sydney.

It told the story of the PSM forensic investigative journey in determining how the Old Pacific Highway at Somersby collapsed in 2007 and the lessons that can be learnt from the event.

The paper "Collapse of the Old Pacific Highway, Piles Creek, Somersby" has been published in the proceedings of the 13th ANZ Conference on Geomechanics, April 2019.
