Foundation Workshop – Logging of Core for Civil Geotechnical Purposes

Joe Gough


The course aims to (further) educate geologists, geotechnical/environmental engineers and geotechnicians who are tasked with logging drillhole core derived from a civil geotechnical investigation. No prior experience in logging rock core is assumed, the aim being to familiarise participants who may not have had much opportunity to log core in the field with the key requirements of core logging for civil geotechnical purposes. In order to accommodate the fact that many organisations have proprietary logging systems, Joe will make use of an encoding system that is used extensively in coal exploration and geotechnical applications but will be shown to be readily adaptable to civil geotechnical applications. Within this context, the course could also be useful for senior level professionals wishing to refresh their general soil/rock logging knowledge and get familiar with the encoding system.

Joe will start the proceedings with an overview of geotechnical logging of soil and rock in accordance with AS 1726 followed by some key finer points of AS 1726. Following this overview, for the remainder of the morning Joe will introduce how rock core observations are entered in the encoding system and outline their current objectives and applications in both civil and mining contexts. After lunch, Joe will lead a practical session where participants will work in small groups to apply the theory and log actual rock core. At the end of the day, outcomes will be discussed in a group session for all participants.


Joe is a retired consultant engineering geologist and has worked across major civil, mining and oil and gas projects around the world since 1975. Joe’s qualifications are from UNSW (BSc (Hons)) and UQ (Masters Qualifying Course). He has worked on investigations and designs for open cut mining, provided input in the design and construction for tunnels, dams, roads and pipelines and has a broad experience in extractive materials resource assessment. The majority of projects worked on by Joe prior to retirement in 2012 have been in the mining industry and this mining experience has formed the basis of several seminar presentations and training courses.

Joe is a member of the Australasian Institute of Mining and Metallurgy and a Member of the Geological Society of Australia.
