This paper presents an article explaining a TBM project overall in Norway. The paper which published in Norwegian TBM Tunnelling by Norwegian Soil and Rock Eng. Assoc. in 1998, contains most of the items considered in TBM tunnelling. New powerplants, tunnels and dams have been built at Meraker in Central Norway. A total of 44 km of tunnels with cross sections varying from $7\;m^2\;to\;32\;m^2$ have been excavated in hard rock formation. Tunnel of 10 km with the 3.5 m diameter was excavated by a HP TBM in a year. his project gives the special attention to the TBM drive and equipment selection, including planning, site organization and performance.
