TC Chair: Giulia Viggiani

Host Member Society: UK and Italy

Short name: Underground Construction (TC204)

Technical Committee 204 (TC204) "Geotechnical Aspects of Underground Construction in Soft Ground", was first established in 1989 as TC28 and is currently in its seventh term. It has completed one term with Prof Keiichi Fujita as Chairman (1989-1995), two with Prof Robert Mair (1995-2005), another one with Prof Richard Kastner (2006-2011), and two with Prof. Adam Bezuijen (2012-2022). The current Chair is Prof Giulia Viggiani.  

The main topics addressed by TC204 concern the geotechnical aspects of the analysis, design, monitoring, construction, and maintenance of deep excavations, tunnels, and large underground structures in the urban environment, with particular emphasis on the development, effects, and control of ground movements, their interaction with existing structures, mitigation measures, and risk management.

TC204 has organised ten International Symposia (IS); the first was held in New Delhi in 1994 and nine more were held in London (1996), Tokyo (1999), Toulouse (2002), Amsterdam (2005), Shanghai (2008), Rome (2011), Seoul (2014), Sao Paulo (2017), and Cambridge (2022).

To recognise his inspirational leadership and enormous technical and organisational contributions in establishing TC204, an Honorary "Keiichi Fujita Lecture" was introduced in 2011, to be delivered every three years at TC204 International Symposia. Distinguished Fujita Lecturers have included Dr Hugh D. St John (2014), Prof Hirokazu Akagi, and Prof Robert J. Mair (2022). Prof Adam Bezuijen will deliver the fourth "Keiichi Fujita Lecture" at IS-Macau 2024.
