Hatch Mott MacDonald received the prestigious ACEC Grand Award at the 2015 Engineering Excellence Awards Gala on April 21. ACEC had this project description in their program:
More than six miles long and 43 feet in diameter, the new Niagara Tunnel is the largest renewable energy project in the world. Providing much-needed power for the city of Niagara Falls, it is located deep beneath the city and is more than one and a half times wider than the English Channel Tunnel.
Peter K. Robertson, Ph.D., P.Eng, Professor Emeritus, University of Alberta, Technical Advisor, Gregg Drilling & Testing Inc. is the 2015 recipient of the H. Bolton Seed Medal for outstanding contributions to teaching, research, or practice in geotechnical engineering. He presented his keynote lecture at the 2015 IFCEE Conference in San Antonio. The title of the presentation was Evaluation of Soil Liquefaction - How Far Have We Come in the Past 30 Years?
A professional river guide came under fire for a rafting trip through the site of the Oso landslide. Families of the victims issued a cease and desist order, but the trip happened anyway. Opponents of the trip likened it to taking a trip through a graveyard, that it was disrespectful to those that died in the tragedy. Others noted that places like the site of the Boston bombing and the World Trade Center did not get to become off limits after their tragedies. The guide said that it was his first and last trip to that site because of the low volume of water. [Source: Read more from Q13 FOX News. Image: Q13 Fox News]
NovoLIQ software by GeoPrac sponsor Novotech allows geotechnical engineers to perform soil liquefaction analysis. NovoLIQ covers several liquefaction triggering analysis including post liquefaction parameters and dry sand settlement. This program covers SPT, Vs and BPT and calculates factor of safety and many other analyses results. [Source: YouTube. Image: YouTube]
National Driller magazine had a nice article not to long ago interviewing Kord Wissman about his transition from consulting to contracting. Kord is the President of Geopier Foundation Company (owned by Tensar). He has some very interesting insights, it's worth the read. I admire Kord as well for his involvement with the Geo-Institute and the GBA, he is very generous with his time and talents, more of us should be like him! I think GBA members can listen to his 'Going to the Dark Side' presentation (which was the impetus for the interview) for free, check the GBA website. [Source: Read the interview at National Driller.

The Bertha TBM just received a shipment of spare parts to repair the giant tunneling machine. The manufacturer decided to redesign the seal system to make it easier to access from the inside, if necessary. That's probably a good idea considering the prospect of a repair like this one once the machine is moving beneath downtown Seattle. Other improvements and repairs to the TBM include:
A new main bearing
Enhanced monitoring systems
Added steel to strengthen the machine and accommodate the new seal system
Widened openings at the center of the cutterhead
Extended arms to mix excavated soil in the chamber behind the cutterhead
The Geo-Institute is proud to announce the launch of its new website! With the same URL as before, www.geoinstitute.org, the website strives to support and communicate the value and dynamism of the geoprofession, preserve its integrity, and foster its growth.
Our easy-to-use website features efficient navigation and search, making our most popular and newest content easy to find. The appealing, new design allows GEOSTRATA articles to be easily accessed and indexed by subject.
The G-I website also hosts autonomously maintained "microsites" for committees and chapters; this allows all the individual websites to be located in one place and fosters communication within the G-I community.
The website looks great. Yours truly served on a task force to provide input on selecting a consultant and various design features. I know it will be a tremendous resource for our profession for many years! [Source: Visit the Updated Geo-Institute Website via G-I eUpdate Newsletter. Image: G-I via ShrinkTheWeb]
GeoPrac sponsor Keynetix has announced some exciting news, a collaboration with the British Geotechnical Survey (BGS) on a research project to develop BIM models for geotechnical and geological data. Watch the video below, or read more in the Keynetix Press Release! [Source: Keynetix]
The City of North Haven is located on an island off the coast of Maine. This town was faced with a unique challenge when a bridge needed replacing. Looking for an economical option, designers decided on a Geosynthetic Reinforced Soil - Integrated Bridge System (GRS-IBS). This solution allowed the town and DOT to re-use an existing bridge pier, beat the construction deadlines, and provide a modern bridge solution for this small town.
