A positive outlook for global tunnelling industry
Whether in the east, west, north or south, global tunnelling and underground development - worth US$100 billion annually - remains a buoyant and dynamic sector. And more growth could be expected with increasing needs for mining applications and rising urban populations leading municipalities to seek underground solutions.
     2016 seems to be a particularly record-breaking year: the recent opening of the Gotthard Tunnel (December 11, 2016) through the Alps in Switzerland exemplifies the outstanding size of projects launched and completed to date. Even though the activity has historically been very strong in Europe and North America, new trends have emerged in the past few years: nowadays, almost 60% of tunnelling projects are located in Asia, 29 cities in China are currently extending or building their metro. Also, the place of South America is globally rising in the Tunnelling industry.
