Principal Engineering Geologist
Principal Engineering Geologist at PSM, Brisbane, Guy Grocott has 40 years’ experience in his field. Throughout his career Guy has worked on a wide range of geological environments across Australia, New Zealand, Indonesia, Papua New Guinea, South Africa, Lao PDR, Iran, India, Mongolia and Western Samoa.
Guy’s areas of practice include skills in natural hazards evaluation, particularly stability of slopes with respect to civil infrastructure development including linear structures (road, rail, pipelines), hydro power and urban development. He also specialises in the design of open-pit slopes for mines.
Other special interests
Guy has a particular interest in the development of geotechnical models for projects such as tunnels in complex geological settings. An example project is the Second Manapouri Tailrace Tunnel Project, where he led the geotechnical studies on behalf of the contractor’s claim for differing site conditions for a 10m diameter TBM driven in mixed face, widely fractured and very hard rock.
Guy’s other areas of interest include the resource assessment of industrial minerals particularly aggregates. He has worked for numerous quarry operators including the assessment of pit stability and the preparation of ground control management and rehabilitation plans.
Guy is a former Chairman of the New Zealand Geotechnical Society Inc. (2000-01), and has served in other roles within this organisation including as Secretary (1982), Editor of NZ Geomechanics News (1983-84), and Committee Member and conference organiser. He is a current Member of the Australian Geomechanics Society and New Zealand Geotechnical Society Inc. He is a Registered Professional Engineer (Civil) and a Registered Professional Engineer of Queensland (RPEQ), an RPEQ Assessor on behalf of Professionals Australia and a member of the International Association for Engineering Geology and the Environment (IAEGE).
Guy is the author of 30 publications including as a contributing author to Engineering Geology of Southern Africa, Vol. 1 (1979) and Vol. 2 (1981).
A graduate of the University of Canterbury, Christchurch, New Zealand, Guy has a Master of Science in Engineering Geology. His academic achievements include the Cotton Memorial Prize and Postgraduate (PhD) Scholarship, Victoria University of Wellington. He was also awarded the McKee Trust Postgraduate Scholarship, University of Canterbury, New Zealand.
Guy specialises in geological and geotechnical studies for small through to large civil and mining projects. His particular areas of expertise include:
- Engineering geology
- Natural hazard assessments, especially related to slope stability
- Open-pit slope design
- Geotechnical models for project development in complex geological settings.
