The construction of Norway's longest railway tunnel marked a breakthrough for the use of tunnel boring machines in hard rock tunnelling. In Scandinavia long rail tunnels have hitherto been drilled and blasted rather than bored. In the Follo Line Project, the tunnel boring machines made a convincing case for themselves all the way through the extremely hard Norwegian rock. Four tunnel boring machines (TBMs) by Herrenknecht worked simultaneously to excavate the main part of two 20-kilometer railway tunnels between Oslo and Ski. On February 26, 2019, the final double breakthrough of the Double Shield TBMs "Anna" and "Magda" successfully completed the challenging mission and drew a spectacular close.
Cimic Group’s global mining services provider, Thiess, through Majwe Mining Joint Venture (Majwe), has secured a A$1.7 billion contract at Debswana Diamond Company’s Jwaneng Mine Cut 9 project in Botswana.
Soil samples in the laboratory may seem a world apart from the gleaming high tech of the high speed train. Yet both share the spotlight in a current exhibition at the National Railway Museum in York giving a rare insight into the role of testing and prototyping in pushing the boundaries of rail engineering.
A consortium of Van Oord and BAM International completed the construction of the APM Terminals Moín in Costa Rica. The inauguration of the container terminal will enable products to be shipped on transatlantic routes to European and Asian markets without transshipment.
