Microtunneling or microtunnelling is a tunnel construction technique used to construct utility tunnels from approximately in diameter. Because of their small diameter, it is not possible to have an operator driving the tunneling machine, so they have to be remotely operated. thumb|Micro tunnel boring

Microtunnel boring machines (MTBM) are similar to larger tunnel boring machines (TBMs). The MTBM and jacking frame are set up in a shaft at the required depth. The operator monitors the MTBM's location, orientation and hydraulic devices via a computer console, a CCTV camera or Gyro unit. Some systems use video cameras in the jacking shaft and at the separation plant. Gyro Control have generally replaced cameras for location and digital feedback.
