Crowds celebrate the opening of the Gotthard Base Tunnel

The Swiss and many other European dignitaries celebrated the opening of the World's longest and deepest tunnel last week, the Gotthard Base Tunnel, after 17 years of construction. The tunnel beneath the Swiss Alps is 57-kilometers long (35-miles long) reaching a depth of 2,300 meters (7,545 feet, almost 1.5 miles). The tunnel will create a high-speed rail link between northern and southern Europe. Trains will travel the tunnel, which runs between the towns of Erstfeld in the north and Bodio in the south, in only 20 minutes, reaching speeds of up to 250 kilometers an hour (155 mph), according to CNN.

Wilson Classical High School in Long Beach, CA

GeoPrac sponsor Nicholson Construction has started a chemical grouting project in Los Angeles at the Woodrow Wilson Classical High School to treat potentially liquefiable soils beneath the building. This $2 million project is part of a larger $21.1 million project to upgrade the infrastructure in the auditorium and adjacent areas. Nicholson will drill vertical, horizontal and inclined holes at depths of 14 to 24 feet beneath the structure and inject the chemical grout using a Tube-a-Manchette piping system.

Introducing Quanta Subsurface

There is a new player in the ground engineering and specialty geotechnical construction market in North America...well, sort of. Quanta Subsurface is a collection of (at present) 9 specialty contractors all owned by Quanta Services, a publicly traded EPC company specializing in the Electric Power and Oil and Gas industries. Many of these companies have been around for some time in their various markets, firms like Crux Subsurface. With the formation of Quanta Subsurface, it appears that they are looking to grow their footprint in transmission line sector in particular. The company is being run by several Crux Subsurface executives, including Crux President Nick Salisbury. [Source: Read more at QuantaSubsurface. Image: Crux/Quanta Subsurface]

Top 500 Design Firms - With a Geo Emphasis

ENR's annual top 500 design firms list is out. These rankings are based on revenue for design services in the previous calendar year. I was curious how the various firms that are strong in geotechnical / geological related services rank. I included firms that self-identified as geotechnical firms, as well as engineering firms that I know to have a strong geo emphasis. I'm sure there are some that I missed. I also included some of the major A&E firms that provide these types of services. I even included a few environmental firms. So in summary, it's still a bit subjective on who is included. Without further ado, here is the list (along with their change in ranking relative to 2015):

  • 1 - AECOM, Los Angeles, Calif. (No change from 2015)
  • 3 - CH2M, Englewood, Colo. (+1)
  • 5 - AMEC FOSTER WHEELER, Tucker, Ga. (+1)
  • 7 - TETRA TECH INC., Pasadena, Calif. (No change from 2015)
  • 9 - HDR, Omaha, Neb. (No change from 2015)
  • 11 - WSP | PARSONS BRINCKERHOFF, New York, N.Y. (+5)
  • 12 - ARCADIS NORTH AMERICA/CALLISONRTKL, Highlands Ranch, Colo. (+1)

From WSDOT's video description:

After nearly a week of tunneling under the Alaskan Way Viaduct, crews are steadily continuing Bertha's underground drive towards downtown Seattle. This video gives you a behind-the-scenes glimpse into how the new tunnel is being built, showcasing the complex operations involved in this project. Massive concrete ring segments are transported to Bertha's segment erector where they are lifted into place, allowing the machine to push forward while the excavated soil is transported along a network of conveyer belts and into a barge moored at Elliott Bay’s Pier 46.

This is a great video from WSDOT visualizing all of the geotechnical instrumentation and survey monitoring being done in Downtown Seattle above the Bertha TBM for the Alaska Way Viaduct Replacement project. Soldata is the company WSDOT hired to manage the monitoring. I heard a great presentation by a Soldata representative and a member of the Seattle Tunnel Partners in charge of the instrumentation and monitoring from the contractor's side several years ago at an AEG conference. You can read more about the amazing Bertha TBM and some of the monitoring being done in my article. [Source: WSDOT YouTube Channel. Image: YouTube]
