Pumped storage hydropower – helping to drive the energy transition
30 October, 2023
With the need to address the intermittent nature of renewable energy sources, pumped storage hydropower can help, says Stantec’s Greg Raines, Vice President, and Don Erpenbeck, Vice President and Global Section Leader (Dams & Hydropower). Underground construction has a role to play in pursuing that path

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
