Digitalisation in construction leads to a decisive advance: according to studies, up to 57% of the work performed in the construction process still has no added value, caused by mistakes and defects, waiting and search times, poorly coordinated sequences and lack of communication. With digitalisation, it should be possible in the future to exploit this potential, enabled by the use of innovative technologies like Concremote. The sensor solution from Doka delivers data of the temperature and strength development of concrete in real time.
The same applies for every tunnel project: segments must be at the right place at the right time. Towards this end, special demands are posed on the transport and storage of these weighty concrete...

In fall 2014 the Chinese company LNSS (Liaoning Censcience Industry Co. Ltd.) acquired the Caterpillar Tunneling Canada Corporation, thus obtaining all intellectual properties of former TBM manufacturer Lovat. A new company “Lovsuns Tunneling Canada” was set up in Toronto. In January 2017 Lovsuns shifted the Canadian TBM production to the LNSS facilities in China. Freelancing journalist Roland Herr spoke with Hongyu Xue, Managing Director of Lovsuns Tunneling Canada, about the reasons for the relocation of the TBM production, about Lovsun’s proposed role in the TBM business in the years ahead and about his view on the growing influence of China in the mechanized tunnelling market.
