Annual General Sessions of IGS are held in different parts of the country. In the early years, Technical Sessions were organized along with the General Body Meetings. Later, these were developed into Symposia. From 1978, regular Annual Conferences have been organized and now they are known as Indian Geotechnical Conferences (IGC). Over the years, it has been the endeavor to bring IGCs to the level of International standard. The proceedings of these Conferences are regularly being published.

Under the auspices of the ISSMGE, the First Asian Regional Conferences was held in New Delhi in 1960 and the Fifth Asian Regional Conference was held in the year 1975 at Bangalore. The 13th ARC is scheduled to be held at Kolkata. Thus IGS will have the distinction of hosting 3 ARCs by any Asian Country.

The IGS had also the unique distinction of hosting the 13th International Conference on Soil Mechanics and Geotechnical Engineering in India at New Delhi, in the year 1994, which was acclaimed as “Magic Carpet Conference”.

IGS will be hosting the 6th IYGEC (International Young Geotech. Engineers Conference) in the year 2008.
