Dr Alun Thomas, Ramboll: Fehmarnbelt Fixed Link Tunnel

841

Published on

Dr Alun Thomas, Head of Tunnels, Ramboll delivered this presentation at the 2013 Australian Tunnelling conference. The two day conference is supported by the Australasian Tunnelling Society and brings together tunnelling leaders, engineers and industry experts to share best practice in tunnelling design, construction, safety and maintenance.

The 2012 program focussed on updates from Australasia’s current and future projects, plus case studies from leading International projects - sharing best practice and lessons learnt from the forefront of the latest tunnelling projects. For more information about the event, please visit the conference website: http://www.informa.com.au/tunnellingconference
