Photographer & Submitter: Brian Fulcher
"I have a passion for underground photography," says Brian Fulcher, of J.F. Shea Construction Co., Walnut, Calif. A tunnel construction enthusiast, Fulcher took this shot of workers on the Gotthard Base Tunnel, Sedrun, Switzerland, a Bilfinger Berger-led joint venture. The crew is installing steel support ribs which, with the shotcrete applied to the tunnel's forward wall, prevent collapse. This portion of the tunnel was bored through "squeezing ground, which pushes in on the tunnel walls," Fulcher says. "It's very dangerous work."
