Principal Geotechnical Engineer at PSM, Irene Chan has 20 years’ experience in  a wide range of geotechnical-related fields. These include civil and hydrologic design and construction, geotechnical and tunnel design and construction, as well as mining design, construction and operation. Irene’s  breadth of experience gives her a unique insight into how water, soil and rock interact with many types of infrastructure.

Since joining PSM, Irene has been involved in major mining projects such as Waihi (New Zealand) and Lihir (Papua New Guinea) gold mines, as well as coal mines in the Hunter Valley and in Victoria. She has also been involved in major tunnelling projects in Sydney, such as WestConnex (M4 East), Lane Cove Tunnel,  Epping to Chatswood Rail Link, and miscellaneous civil projects in Sydney.
