The 6th International Conference on Geotechnical and Geophysical Site Characterisation, ICS’6, took place on 26-29th September 2021 in Budapest. This unique conference welcomed over 175 delegates as well as over 250 online participants during the 4-day event which was organised by the Hungarian Geotechnical Society.

A series of invited lecturers on geotechnical characterisation codes, seismic site characterisation, liquefaction and settlement analysis based on site investigation techniques and advances in numerical modelling from CPTU were followed by the Mitchel Lecture which was presented by Prof. Fernando Schnaid on ‘Geo-mechanics and geo-characterisation of tailing’.

During 20 parallel sessions, topics such as liquefaction, special soils characterisation, soil models from in situ tests, numerical modelling and links between test results and material parameters, geophysics, environmental testing, equipment, evaluation, verifications and pile designs based on in situ tests were presented and discussed.

In Situ Site Investigation participated in the conference with a new study on the impact of cone penetrometer sleeve diameter on sleeve measurements. The research work carried out for the purpose of this paper was led by Dr. John Powell of Geolabs and the results were presented by our geotechnical engineer, Luisa Dhimitri during the Equipment and Tests section of the event. The conclusions and recommendations of our research work have been adopted in the draft revision of the ISO Standard. To download our paper titled ‘Does size matter?’, please click here:
