Tunnel boring isn't an easy job. The TBM uses 25,000 bhp (18,600 kW) and moves at a speed of about 35 ft (10 m) per day. Though the system is largely automated, Bertha still needs 25 people at a time to keep it going.
The reuse of machines can, if done to exacting standards, reduce costs and time to deliver. ... International guidelines have been developed to standardize the process of reusing a TBM for another project.
The wheels are turned by friction as the cutting head rotates and hydraulic cylinders push from behind. This thrust is a function of the number and size of the cutting discs. The thrust a TBM can place on a disc goes up with the square of its diameter, according to John Turner, chief engineer at Robbins.
