Ranked amongst the most important tunnel-boring machine manufacturers on the world market, NFM Technologies provides its customers with tunneling machines of 4 to more than 15 metres in diameter, suited to all types of geology, acknowledged for their reliability and robustness.
Tunnel boring work on the Forrestfield Airport Link has reached a milestone point, breaking through the new station wall at the weekend. The breakthrough, which was delayed for more than a month earlier this year because of ground disturbances, means a quarter of the 8km of tunneling work has been completed.
If a major breakdown occurs during tunneling, the resulting downtime and repairs can delay construction for months and send costs soaring. During tunnel boring machine development projects, breakdowns can be equally damaging – a main bearing failure can stop a project for up to two years.
