Profession tunnel boring machine operator

Tunnel boring machine operators work on large pieces of tunnelling equipment commonly known as TBMs. They regulate the operation of the machine, adjusting the torque of the rotating cutting wheel and screw conveyor to maximise stability of the tunnel before tunnel rings are installed. Tunnel boring machine operators then put the reinforced concrete rings in place using remote controls.

Personality Type

• Realistic / Conventional
• Realistic / Enterprising
• Realistic / Investigative

Knowledge

• Mechanical systems

  Mechanical systems, including gears, engines, hydraulic and pneumatic systems. Their functions and likely defects.

• Mechanics

  Theoretical and practical applications of the science studying the action of displacements and forces on physical bodies to the development of machinery and mechanical devices.

• Tunnel boring machine console

  Functions of the buttons, switches, gauges and monitors on a tunnel boring machine console.

Skills

• Drive tunnel boring machine

  Steer the tunnel boring machine based on input from navigation devices. Operate the hydraulic rams in a timely and precise manner to stay on course.

• Follow health and safety procedures in construction

  Apply the relevant health and safety procedures in construction in order to prevent accidents, pollution and other risks.

• Install tunnel segments

  Set the reinforced concrete tunnel segments in place after the tunnel boring machine has excavated sufficient space. Base the position of the segments on the plans or calculations for optimal placement.

• Transport construction supplies

  Bring construction materials, tools and equipment to the construction site and store them properly taking various aspects into account such as the workers' safety and protection from deterioration.

• Work ergonomically

  Apply ergonomy principles in the organisation of the workplace while manually handling equipment and materials.

• Use safety equipment in construction

  Use elements of protective clothing such as steel-tipped shoes, and gear such as protective goggles, in order to minimise risk of accidents in construction and to mitigate any injury if an accident does occur.

• Operate theodolite

  Operate an optical or laser theodolite, precision instruments used to measure angles.

• Tend boring machine

  Tend a boring machine, monitor and operate it, according to regulations.

• React to events in time-critical environments

  Monitor the situation around you and anticipate. Be ready to take quick and appropriate action in case of unexpected events.

• Prevent damage to utility infrastructure

  Consult utility companies or plans on the location of any utility infrastructure that may interfere with a project or be damaged by it. Take the necessary steps to avoid damage.

• Switch tunnel boring machine modes

  Monitor the process of switching the tunnel boring machine from boring mode to segment placement mode and vice versa.
