Excavator-mounted cutting attachments have become established in tunnel projects of the Austrian construction group Porr and in other construction companies. The wide range of applications is carried out with both standard and special cutters. In some cases, even excavation of the tunnel is carried out using cutting technology. In soft rock, this offers an advantage over blasting, because the bedrock is not damaged by vibrations. Moreover, numerous other operations in tunnel construction and rehabilitation are made possible by excavator-mounted cutting attachments.

On 31 July 2021, Roy Forbes, long-time translator of the trade journal tunnel, died – after a long illness, but nevertheless surprisingly. He never ceased to be enthusiastic about the many different subject areas of tunnelling, and even at the age of 78, forced to take a break from work due to illness, he was looking forward to “translating for tunnel again soon”. The tunnel staff mourns the loss of a colleague from the very beginning. A decades-long excellent cooperation connects us with Roy Forbes. Excellent because it was not only professionally successful but also fun for all of us. We miss him very much.
