The 4th Arabian Tunnelling Conference (ATC 2017), held in conjunction with the 20th Gulf Engineering Forum (GEF 2017), takes place on the 21-22 February 2017 at the Ritz Carlton in Dubai International Financial Center, United Arab Emirates.The ATC is the number one networking hub of Tunnell
EURO:TUN 2017 is the fourth conference of a series of successful ECCOMAS Thematic Conferences on Computational Methods in Tunneling, started in 2007 in Vienna and continued in 2009 and 2013 in Bochum.
Every two years, industry leaders and practitioners from around the world gather at the Rapid Excavation and Tunneling Conference (RETC), the authoritative program for the tunneling profession, to learn about the most recent advances and breakthroughs in this unique field. Dr.

The BSCES Geo-Institute will be holding a one-day seminar on "Recent Advances in Geotechnical Engineering" on Saturday, October 29, 2005 at Bentley College. Over ten speakers will cover topics such as recent advances in automated data collection, field testing, composite/light weight materials, alternative foundation systems and innovative tunnel construction techniques.
July 5, 2005 - Just arrived at the Port of Seattle, Sound Transit's new Mitsubishi tunnel boring machine (TBM) after transport from the factory located in Kobe, Japan. The TBM will be used to construct the twenty foot diameter parallel running tunnels for Sound Transit's Link Light Rail through Seattle's Beacon Hill. The tunnels will pass through the Beacon Hill Station complex located mid-way along the line as shown below.
The 2005 Rapid Excavation and Tunneling Conference was held in Seattle, WAfrom June 27 - 29, 2005. This year’s conference offered a diverse array of interesting papers that spanned all aspects of underground construction and tunneling, as well as a forecast for future projects. One of the highlights of the event was a site tour atSound Transit's Beacon Hill Station project site. The underground station will be a crucial part of the Seattle Link Light Rail expansion and was designed by the Dr. G. Sauer Corporation (DSC) as a subcosultant to the Hatch Mott MacDonald / Jacobs Joint Venture.
With the recent opening of the Silverline Phase II the MBTA did not only put in service a 2 mile long section of running tunnels containing technically challenging segments such as immersed tubes through the Fort Point Channel and NATM binocular tunnels at the historic Russia Wharf Building, but also opened two new underground stations along the alignment.
The construction at Sound Transit's Beacon Hill Station is progressing on schedule. The construction of slurry wall panels for Headhouses and Shafts has been started recently.
Meanwhile, exploratory drilling is under way to determine the extent of water bearing sand and silt layers. These will be improved by jet grouting from the surface and dewatering with deep wells.
On 22 December 2004 President Lagos opened the third and last segment of a line extension program undertaken by Metro Santiago over the last five years. The Line 2 South Extension will add 2.3km of track and two stations to the network of Santiago Metro. The terminal station, La Cisterna at the intersection of Gran Avenida José Miguel Carrera and Américo Vespucio Sur Beltway, two major highways in the south of Santiago, will be the future connection to the western spur the new Line 4, currently under construction. The line extension was designed and constructed in less than five years and the cost for the civil works were slightly below $30 million.
The d2 “Dulles Development” began in 2000 and passengers have benefited from some of the many planned improvements. One such improvement will open to the public next month.
On October 20th 2004 Dr. Gerhard Sauer presented a lecture on his article "Tunneling and Beyond" in Prof. Russel Clough's construction management class at Stanford University.
The Audience consisted of graduate students and interested members of the industry.
The Port Authority of Allegheny County is currently undertaking an expansion of the T to the north of the city which includes 3 underground stations and 1 aerial station connected by bored tunnels under the Allegheny River, cut-and-cover tunnels and a mined tunnel using NATM.
The Dr. G. Sauer Corporation, a subconsultant for DMJM+Harris, is responsible for the waterproofing design of all cut-and-cover and mined structures as well as the NATM design of a 440 foot section of double track tunnels south of the proposed Convention Center Station.
