Liebherr's foundation drill rig equipment simulator in action

Equipment manufacturer Liebherr has created a new simulator to allow operators to train on foundation drilling equipment virtually. The simulator is based on other simulators created by Liebherr, and includes things like a real construction site with neighboring buildings and structures, uneven ground, varying soil conditions, etc. [Source: Read more at GE Innovation News | New Civil Engineer via @GE_magazine.

View of failed Baltimore retaining wall before soldier pile wall construction

Hayward Baker was among the contractors called in for emergency repairs to a failed retaining wall in Baltimore that destabilized a slope, causing a landslide that enveloped cars and threatened a railroad track below. The final episode of the slope failure was caught on video and showed several cars being swallowed. GeoPrac sponsor, Hayward Baker is currently on-site installing a temporary soldier pile lagging wall with tiebacks to facilitate the construction of a permanent wall. They are anticipating to have the temporary wall complete in August. [Source: Read more about the project at Haywardbaker.com. Image: Hayward Baker]

Micropile foundations with Crux' patented steel micropile cap design for the Sunrise Powerlink Project

Congratulations to Crux Subsurface, Inc. on winning the Deep Foundation Institute's (DFI) 2014 Outstanding Project Award (OPA) and the 2014 C. William Bermingham Innovation Award for their Sunrise Powerlink Project in California. The project involved the installation of over 3,700 micropiles for the foundations of new steel lattice towers for a 117 mile transmission line running from Imperial Valley to San Diego. All of the micopiles were installed using rigs and equipment mobilized by helicopter in the difficult terrain. The project was the first to use Crux' patented steel micropile cap, which is what they were awarded the Bermingham Innovation Award for. Crux credits the steel cap design for reducing the on-site construction time by 64%. [Source: Read more about the awards from the Deep Foundations Institute (DFI). Image: Crux Subsurface, Inc.]

Access Road Construction for Geotechnical Investigation

Geotechnical work has commenced for a project involving reconstructing the Historic Columbia River Highway in Hood River County as a segment of Oregon's Historic Highway State Trail. The geotechnical scope consists of 48 test pits, 58 boreholes, and constructing 4,000 linear feet of temporary access roads. [Source: Hood River News. Image: Hood River News]

World Cup 2014: a landslide affects the city of Natal in Brazil

Brazil soccer/football fan surveys the landslide damage in Natal

Torrential rain in the World Cup city of Natal caused a landslide right around the time that the USA defeated Ghana. According to the Landslide Blog, the landslide destroyed 50 homes but there were no lives lost. A You-Tube Video showing the landslide as seen from a small UAV shows the devestation, and interestingly shows a storm drain that could have played a role in the failure, perhaps becoming overwhelmed after the 50 hours of rain that fell on Natal.

2014 Terzaghi Lecture - Carlos Santamarina

Dr. Carlos Santamarina of Georgia Tech. presented the 2014 Terzaghi Lecture at Geo-Congress 2014 entititled 'Energy Geotechnology: Enabling New Insights Into Soil Behavior'. From the You-Tube summary:

Energy is critical to life, and the coming decades will see worldwide population growth and associated economic development that will result in a pronounced increase in energy demand. Historically, geotechnical engineering has been crucial to projects that have sustained societal transformations. Once again, geotechnical engineering has a central role to play in the evolving energy challenge, from resource recovery and infrastructure development, to energy storage and waste management. Examples during this lecture and details in the accompanying manuscript show that the emerging field of energy geotechnology drives us to reconsider the basic tenets of geotechnical engineering (such as soil formation, index properties, and classification), to extend our understanding of geomaterials (at high pressure and temperature, long time scales, and large number of repetitions), to recognize new phenomena (most often couplings between hydraulic, thermal, chemical, biological and mechanical processes, and various forms of localization), and to advance technological innovations for characterization (in situ, sampling, and laboratory) and monitoring.

Alliance Formed for the Commercialization of BioJet Technology to Solve the Challenges of Environmental Remediation in Low-Permeability Contaminated Soils

Hanover, MD (PRWEB) June 25, 2014

Hayward Baker and Chemical Grouting Co. present BioJet TechnologyHayward Baker Inc. (HBI) announces the formation of a strategic alliance with EOS Remediation, LLC (EOS, Raleigh, NC) and Chemical Grouting Co., Ltd. (CG Co., Tokyo, Japan) for the commercialization of the BioJet™ technology.

BioJet technology provides a solution for one of the most difficult challenges of environmental remediation in low-permeability (clays and silts) contaminated soils. The technology uses high velocity jetting tools and CG Co.’s geotechnical analysis to create intimate contact between the engineered remediation products by EOS and the contaminants by “cutting” circular slots in the soil and allowing effective distribution of the remediation products throughout the low-permeability soils.

VA Company Uses NCFI's TerraThane Geotech Foam System to Save Parking Lot, Time, and Money for NC Municipality

TerraThane and Concrete Jack Fixed this Parking Lot

MOUNT AIRY, NC—Concrete Jack, Inc. of Williamsburg, VA, a company specializing in concrete leveling and foundation repair along the Eastern Seaboard and the South, used TerraThane Geotechnical Foam system to help save the parking lot of a Wake Forest, NC auto repair business.

"Parking lots are notorious for sinking from failed storm water structures," says Kirk Roberts, division manager for Concrete Jack. "Water causes erosion around the structures, voids form, voids enlarge over time then the parking lot just collapses. Sinkholes can shut down businesses and cause damage to customer vehicles."

Roberts says the municipality's public works department determined the joints between the four foot sticks of pipe had been improperly gasketed, or seated, during installation. The pipe saw a continuous flow from a small stream entering at an end wall and discharging into a box culvert crossing a public street. The drop inlet at the downstream junction between the RCP culvert and box culvert also failed at the 18-inch RCP culvert feeding it, which had been repaired multiple times using open trench excavation.
