A past President of the ITA, he combines university professorship in his native Brazil with lecturing and Ph.D. jury work abroad. He has written academic papers on sprayed concrete and on complex loading conditions in asymmetric geologies among many other topics; and, he remains a working engineer, leading Geotechnical Engineering for Themag Engenharia Ltda on projects in South America and around the world. He spoke to Julian Champkin
  • 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
