In an instant, the sharp alpine air thickens to a torpid heat reaching nearly 40°C. The temperature rise is a function of geology, not meteorology­—we are deep inside solid rock, in the 57-km-long Gotthard Base Tunnel. More than 1,800 m of mountain is piled above our heads. “This is extremely high-­pressure rock and the water pressure is also very high,” says Renzo Simoni, a Swiss civil engineer and CEO of AlpTransit Gotthard AG, the company that is overseeing one of the world’s most ambitious engineering projects, as he guides us along a dark tunnel track. “Working in these conditions is very, very hard.” Opini Anda Klik untuk menuliskan opini Anda tentang koleksi ini!
