Analysing International Tunnel Costs

Individual tunnel comparisons of six recent urban, TBM bored, rail projects supported the conclusion that tunnelling is not more expensive in Australia. It was found that the costs per cubic meter of these tunnels were very similar and differed by $70/m3. Since the excavation type and end-use were kept constant in this analysis and similar global

Tunnel boring machine Wikipedia

A tunnel boring machine (TBM), also known as a "mole", is a machine used to excavate tunnels with a circular cross section through a variety of soil and rock strata.They may also be used for microtunneling.They can be designed to bore through anything from hard rock to sand.Tunnel diameters can range from one metre (3.3 ft) (done with micro-TBMs) to 17.6 metres (58 ft) to date.

Proactive Maintenance When you virtually “live” in the tunnelling space every day, you observe firsthand the merits of a sound maintenance program. And the absolute downside when there is not. Holding back funds for timely and appropriate maintenance on any TBM system infrastructure is a totally misleadingly and false economy on any company’s balance sheet.

Pioneering lifecycle approach to revolutionise tunnelling

The NETTUN team built a robotic maintenance system for TBM cutter tools to automate routine yet hazardous tasks. The system is equipped with a robotic arm on which dedicated and interchangeable grippers can be mounted to handle disc cutters or drag bits. It reliably handles the complete tool replacement procedure.
