Njemile Faustin, Mohammed Elshafie and Robert Mair, won the British Geotechnical Association’s 2022 Case Histories Award for their Case studies of circular shaft construction in London.
Involving a broad range of geotechnical projects, the British Geotechnical Association (BGA) received a total of 16 entries for the inaugural Case Histories Award, that caused the selection of the winner a long and considered task.
According to the judges’ common statement, the paper on Case studies of circular shaft construction in London represented an outstanding contribution to the knowledge and experience of the UK geotechnical engineering profession.
It rigorously compiled a review of circular shafts from 27 case studies from three major tunneling projects, providing a valuable database of surface settlement performance in an area of few previously well documented case studies, the judges said. 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.
Also in order to helping the UK industry’s future tunneling 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 genuinely useful database is presented in normalized charts.
In 2018, this paper was published in the Proceedings of the Institution of Civil Engineers – Geotechnical Engineering 171(5), while it was written by current Aecom principal geotechnical engineer Njemile Faustin; Qatar University associate professor Mohammed Elshafie; and former Institution of Civil Engineers president Robert Mair.
Encouraging and recognizing the importance of the exchange of exemplary geotechnical knowledge and experience of the performance of constructed works, are the aims of creation of the BGA Case Histories Award.
