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

Observations and modelling of rock mass discontinuities
27 March, 2023
An alternative method for calculation of asymmetrical displacements in cases of predominant foliation is provided, based upon tunnelling experience from Lot E52 (Wolf) and Lot H51 (Pfons- Brenner) on the Austrian side of the Brenner Basistunnel. The paper is by Cristian Paduano, with Lombardi Group as Planning Manager for Brenner Basistunnel Nord PG BBT N, as JV for the planning, and Heimo Schierl, as geological supervisor with Brenner Basistunnel BBT SE
