New Initiative Modeled After Longstanding Bridge Program
WASHINGTON –The U.S. Department of Transportation’s Federal Highway Administration (FHWA) today published the final rule for national tunnel inspection standards that will serve as the foundation of the nation’s first standardized tunnel inspection program. It will be modeled after the FHWA’s successful bridge program established nearly a half-century ago to ensure the safety of the nation’s bridges.
After the 2011 Fukushima earthquake, the reactors at TEPCO's nuclear facility began leaking radioactive groundwater. The plan to contain the contamination is to use ground freezing to construct an "ice wall" to cutoff the flow. Acton, Massachusetts based Geocomp has been contracted by TEPCO to provide engineering services for the ground freezing. Geocomp has subcontracted specialty geotechnical contractor and GeoPrac sponsor Moretrench to provide their specialty ground freezing [...]
The 2015 International Foundation Congress and Equipment Expo was held in San Antonio back in March of this year. The proceedings from IFCEE 2015 are now available online and for purchase at the ASCE Library. However, they are offering a selection of papers for free for a limited time, you just need to be registered with ASCE Library. You can register for free to get access if you haven’t already.

Turning a 119 year old brewhouse into a four-star boutique hotel is no easy task. For the project to be a success, the structure had to literally be raised from it’s grave.
Pearl Brewery operated from 1883 until 2001 in their downtown San Antonio, Texas location. It was once the largest brewery in Texas, and even kept afloat during the Prohibition era. Today the 22- acre Pearl site grounds has become a culinary gathering place where you can eat, live, learn, and play on the banks of the [...]
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.I blogged about this [...]
GeoPrac sponsor Moretrench was very active at the recent Rapid Excavation and Tunneling Conference in New Orleans earlier this month. VP Paul Schmall helped teach a short course on grouting in underground construction, and Director of Ground Freezing Technology, Joe Sopko, co-chaired the Grouting and Ground Modification technical session, and there were three technical papers presented on Moretrench projects.

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 [...]
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:
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' [...]
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 bearingEnhanced monitoring systemsAdded steel to strengthen the machine and accommodate the new [...]

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.
