Arnold Dix – Interview
28 March, 2024
A tunneller with 100 million website hits? Unlikely, surely, but Arnold Dix is an unlikely tunneller. A tunneller is not supposed to be a successful barrister, a national icon, or be world famous. Dix has, accidentally, become the exception. He is, as well as all that, the current President of the International Tunnelling and Underground Space Association (ITA-AITES); this April he is to chair ITA’s annual Member Nations General Assembly meeting at the World Tunnel Congress (WTC 2024) in Shenzhen, China. Julian Champkin spoke to him

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
