Harding Memorial Lecture: Innovations for Tunnels - A Construction Company's View

How will Robotics and Digitalization shape the future of our tunnel industry? On three recent tunnel projects in Hong Kong, Bouygues Construction has developed and implemented innovative methodologies and tools to overcome major challenges that always come with mega-scale projects (see Flyer for details). The key driver behind these innovations is first and foremost safety and risk mitigation, but it turns out that these novelties actually brought significant improvements in operational performance as a side effect. A new era of innovation for our tunnelling industry is being explored - what will come next?

Tideway TBM Delivery

At Greenwich Pumping Station, a large acoustic enclosure is being constructed over a diaphragm wall drop shaft in preparation for TBM delivery and lowering to construct the mega Tideway Tunnel. However existing underground tunnels must be protected from the delivery loading of the TBM. In particular a maze of deep existing brick sewers and underground sewerage chambers had to be protected from TBM transiting directly overhead. This presentation will give a detailed review of the inception, design, construction and full scale load testing of a pile assist RC raft protection system, which also doubles up as the foundation of the acoustic enclosure and gantry cranes for TBM delivery.
