Robert Mair – Interview
28 February, 2024
Few in the tunnelling world are known to the general public, fewer still are profiled in a broadcast programme such as on BBC’s prestigious ‘The Life Scientific’ on Radio Four. In fact, only one has been accorded that mark of public recognition and interest – Robert Mair, Emeritus Professor of Civil Engineering at Cambridge University, and recent Master of Jesus College there, and is past-President of the Institution of Civil Engineers.

Focus on active management
24 January, 2024
Three themes among many at the 10th International Symposium of Tunnel Safety and Security (ISTSS), held in Norway last April, were focused on active management – of Safety, Emergency and Evacuation in underground transport. But while themes exist as do disciplines and specialisms, there was also a message of whole systems thinking – to appreciate and work with lies beyond your own discipline for the greater, safer, good

BIM-based ground modelling for tunnel projects
30 October, 2023
The trend for digitalisation in geotechnics and tunnelling has been spearheaded by developments in BIM. But despite advances, BIM ground modelling remains a challenge due to the inherent heterogeneity and uncertainty of ground conditions, which are difficult to describe and model. This paper presents a new concept and framework for ground modelling in BIM. It looks at state of the art use of the approaches on Austria’s Angath Tunnel project and discusses also what is required still to enable industry-wide adoption. The work on BIM ground modelling contributes to standardised and comprehensible work processes, and also gives a stronger foundation in data to support decision-making
