2022 BGA Case Histories Award Winner announced

The British Geotechnical Association (BGA) is pleased to announce that the 2022 BGA Case Histories Award has been awarded to authors Njemile Faustin, Mohammed Elshafie and Robert Mair for their paper “Case studies of circular shaft construction in London” Proceedings of the Institution of Civil Engineers – Geotechnical Engineering 171(5) published 2018.

The paper can be accessed via the ICE Virtual Library here.

There was a total of sixteen entries received for the inaugural award this year covering a broad range of geotechnical projects, making the selection of the winner by the prizes sub-committee a long and considered task.

The judges agreed that this paper represented an outstanding contribution to the knowledge and experience of the United Kingdom geotechnical engineering profession. It rigorously compiled a review of circular shafts from 27 case studies from three major tunnelling projects, providing a valuable database of surface settlement performance in an area of few previously well documented case studies. Field observations of ground surface settlement were collected and assembled from different circular shafts recently constructed to give an indication of the magnitude of settlement in typical London Basin strata. The genuinely useful database is presented in normalised charts to help the UK industry’s future tunnelling and circular shaft projects make estimates of settlements due to circular shaft construction in London, with due consideration for different shaft geometries and construction methods.

The BGA Case Histories Award is to encourage and recognise the importance of exchange of exemplary geotechnical knowledge and experience of the performance of constructed works. The award is presented for an outstanding contribution to the knowledge and experience of the United Kingdom geotechnical engineering profession through the publication of a well-considered and researched case history or histories, or the publication of recommended practices or design methodologies based on the evaluation of case histories that provide beneficial insights into the geotechnical aspects of constructed works.
