WSP Experts to Share Best Practices and Innovations at World Tunnelling Congress (WTC) 2020

Last week, our WSP experts shared six presentations on the latest insights gained from working on complex geotechnical projects across Australia such as the West Gate Tunnel, Sydney Metro and Green Square.

The theme for this year’s WTC virtual conference was Innovation and Sustainable Underground Serving Global Connectivity. Our lineup of speakers included Paul Hewitt, Technical Executive in Geotechnics and Nick Taylor, Principal Civil Engineer in Water, who presented on microtunnelling on the Green Square Stormwater Drain project. They discussed innovations in trenchless construction that offered an alternative, value-for-money approach that reduced impacts on the environment and the community.


Other speakers included Associate Professor (Dr.) David Och, Senior Principal Engineering Geologist, who presented his discovery of a fine ‘tuff’ lamination in the upper Triassic sedimentary rocks of the Sydney Basin that were identified from drilling on the Sydney Metro Project. This discovery is providing valuable geological insights to ground conditions along future infrastructure corridors and geological sciences in general.


In addition, Andy Noble, Technical Executive – Hydropower and Tunnels, provided his insights on managing risk on Hydropower projects, from a Lenders Technical Advisor’s perspective, based on his experiences gained across his portfolio of global hydropower projects.


Doug Graham, National Executive for Geotechnics & Tunnels, says, “Despite the global pandemic, WSP’s involvement in infrastructure projects has continued across Australia, and the team has been very busy delivering our geotechnical and tunnelling capabilities.


“A lot of the work we are involved in includes future proofing our projects – getting them Future Ready. Some of the trends we’re considering include water scarcity and renewable energy, and densification and automation. Taking our transport modes underground is a result of densification, and automation of transport modes is becoming more common. Water scarcity is driving the development of infrastructure where we can include renewable energy emblements such as pumped hydropower schemes.”
