Aurecon and Seequent lead on NZ’s largest transport infrastructure project
Global engineering and infrastructure advisory company Aurecon and Seequent, a developer of revolutionary visual data science software, are leading the way for digital engineering on New Zealand’s largest transport infrastructure project ever to be undertaken. Auckland’s City Rail Link (CRL) project is a 3.45km twin-tunnel underground rail link up to 42 metres below the city centre, transforming the downtown Britomart Transport Centre into a two-way through station that better connects the Auckland rail network. Infrastructure projects this size are challenging enough, without the added complexity of building them in a city located on a volcanic field. Embarking on a massive project like the CRL through an area of complex geology, including volcanoes, requires a very clear assessment of the ground conditions. This demanding task fell on the shoulders of Aurecon. To help attain and communicate this detailed technical analysis, Aurecon used Seequent’s 3D geological modelling solution, Leapfrog Works, which is specifically designed for the Civil Engineering and Environmental industries. Helping reduce risk on infrastructure projects Critical in any major infrastructure project, Aurecon needed to carry out detailed technical analysis of the ground conditions to identify the risks and then clearly communicate and mitigate these risks to the consortium of engineers and architects involved. Philip Kirk, Geotechnical Team Leader, Aurecon, says, “We didn’t want the construction team to encounter unexpected ground conditions that would compromise or delay the project. We had to get it right.” Seeing the complex volcanic geology To make informed decisions on structural design, services locations and construction methods, engineers and construction teams needed to ‘see’ how these ground conditions interacted. Using Leapfrog Works, Aurecon’s ground engineering and engineering design colleagues were able to readily visualise in 3D and were quickly surprised by how effective a communication tool Leapfrog Works was.
