Advance in construction technology has enabled longer and larger tunnels to be built, and hence more E&M services are being installed along the tunnels to provide ventilation, lighting, security, communication, and fire service etc. There is an increasing demand, for construction workers, to install the E&M services and cladding, in particularly, drilling anchors and installing permanent utility containment system including cable brackets and cable trays. Current practice requires a surveyor or lineman to set out the anchors holes. Then a worker work on cherry picker or working platform to drill each of the holes repeatedly by using a hand-held drill. The anchors could hence be installed in the holes after holes cleaning. High quantity of anchors requires painful and repetitive job - very frequent change of drill bits by hand.
