Counting geoscience measures
Bentley’s subsurface specialist company, Seequent, recently published its latest report on data management trends, challenges and opportunities in geoscience
Pumped storage hydropower – helping to drive the energy transition
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
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
Trenchless solutions serve Red River Valley needs
Key infrastructure to meet vital water supply needs in Red River Valley, North Dakota, were met with the help of trenchless tunnelling. The project is described by Victoria Encapera, Aswathy (Ash) Sivaram, Kurt Ronnekamp and Kayla Christopher of Black & Veatch

Stronger for the Next 50 Years
To help deliver on the ambitious agenda that got him elected barely 12 months ago, ITA President Arnold Dix has had a whirlwind year of near non-stop global travel. As promised to the organisation’s gathering on the occasion of the World Tunnel Congress (WTC), in September 2022, in Copenhagen, Dix planned to act fast and relentlessly in pursuit of the mission that got him elected, unopposed. Since then, he has built momentum for speedy delivery, barely stopping on the way. Here, he outlines for T&T readers what has been achieved so far and what is coming next
Helping to See the Way Ahead
Lighting technology has advanced in recent years to bring sufficient cost-effective, environmentally well-performing illumination to underground settings in support of health & safety as well as construction efficiency on projects. Darren Woodhouse, Lighting Director of LMXLED, discusses with T&T the developments and options of using LED systems in tunnel projects
