The award was instituted in 2008 in memory of the prominent geotechnical engineer John Mitchell of Arup, who was killed while observing piling works at a central London site in 1990.

The award criteria considered by the BGA include the following:

  • In reflection of John Mitchell’s career, selection will favour practical applications of up to date geotechnical concepts or models (rather than advanced theoretical academic practice).
  • The BGA will consider individuals, like John, who in the course of their careers via incremental works have made significant contribution to geotechnical practice.
  • Notwithstanding the above, the BGA will in addition consider any contemporary practitioner who has instigated a major advance in the geotechnical field, thus opening the award up to the innovative, regardless of age or incremental contribution count.

The Award winner gives the John Mitchell Lecture at a BGA Evening meeting the January following the year of the award.
