WTC 2016 Heads to San Francisco

The Underground Construction Association and the International Tunnelling Association (ITA) will host the 42nd annual World Tunnel Congress and General Assembly in San Francisco, April 22-28, 2016. It marks the first time the World Tunnel Congress has been held in the United States since 1996, when it was held in Washington, D.C.

Organizers are expecting more than 2,500 delegates from around the world to the Moscone Center in the heart of San Francisco. The top-tier technical session features 800 industry speakers while the 138,000-sq ft exhibit hall will host more than 200 exhibitors from around the globe. The World Tunnel Congress also features the annual ITA general assembly, where representatives from member nations get together to report on their latest initiatives and discuss the future of ITA. ITA training and educational sessions and working group meetings are also on the schedule.

The theme of the WTC 2016 is “Uniting the Industry.” WTC 2016 in taking the place of the North American Tunneling Conference, which will return in 2018. Urban underground space use is rapidly increasing worldwide as a result of urbanization as well as the need to build or improve infrastructure systems. The World Tunnel Congress provides the venue for industry professionals from across the globe to learn from others as we address the challenges.

San Francisco itself is a prime attraction, with a wealth of sites, attractions, shopping, restaurants and entertainment. Its location on the Pacific Coast provides a gateway for Asian as well as European delegates.

World Tunnel Congress promises to be a great event for both the U.S. market and the global market as well. TBM: Tunnel Business Magazine looks forward to taking part in the show and we hope to see friends old and new in San Francisco.
