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

Tuesday, 01 July 2014 00:14

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.

DFI Forms New DFI Technical Committee: Subsurface Characterization for Deep Foundations
GeoNews - Press Releases

Thursday, 05 June 2014 21:50

DFI_LogoHawthorne, NJ (May 28, 2014): DFI announces the formation of a new, 16th technical committee focusing on site investigation for deep foundation design and construction.

The Subsurface Characterization for Deep Foundations Committee was formed to increase awareness of the importance of complete and competent site investigation in deep foundation practices. The specific goals of the committee will be defined by the committee members, however, initially the committee will discuss and define subsurface characterization needs from the point of view of the entire geotechnical/foundation industry. This will facilitate getting correct and comprehensive information to the end users (designers and contractors) and minimize change condition issues/debates. The committee will liaise with associated committees from other organizations and agencies to broaden the discussion within the engineering community. The objective is to find the common ground that allows the entire geotechnical industry and all project participants to minimize disagreement during construction, align expectations, and improve communication and understanding among related parties.

Thursday, 05 June 2014 07:24

Keynetix_Geotechnical_Academy_1Keynetix are delighted to have been offered the opportunity to be a regular contributor to the Geotechnical Academy starting in June 2014.

The Geotechnical Academy is a collaboration between Equipe Group and Geotechnical Engineering Ltd, providing fundamental technical and commercial training to aspiring geo-professionals, helping them to apply their theoretical and technical understanding in the practical and commercial world.

The training experience is different from other more traditional offerings, in that it will take a group of delegates and their sponsors on a journey over a whole year, to greater knowledge and appreciation of their subject.

Roger Chandler of Keynetix will be taking part in the training sessions that will form part of this fantastic academy. Here he will be raising awareness in the industry of the importance of Geotechnical Data Management, AGS, BIM and the new BS 8574.

“The Geotechnical Academy is a great opportunity for both new and experienced engineers and it is great to be able to contribute to one of the modules.” says Roger “Good geotechnical data management is vital in today’s workplace and I find teaching this to engineers very enjoyable and rewarding. I’m looking forward to helping engineers experience some exciting light bulb moments over the coming months and then giving them practical advice on how to make better use of their time and geotechnical data.”

Roger comes from a Geotechnical background and has been an active member of the AGS Data Management Committee since 1997, a member of DIGGS Cone SIG since 2005 and was the co-author of AGSM.

Equipe TrainingLiz Withington of The Geotechnical Academy says “This is on-the-ground practical development for early stage career geo-professionals. The Geotechnical Academy is a partnership between Geotechnical Engineering Ltd & Equipe Training, providing unique, high quality vocational geotechnical CPD development for early career engineering professionals. We are delighted to have Roger Chandler from Keynetix as a regular contributor. Rogers’s innovative approach to geotechnical data management demonstrates The Geotechnical Academy’s commitment to challenging young geo-professionals in to stimulating change within the industry“

Attendees of the academy will gain knowledge, join in practical demonstrations of equipment and techniques, take part in discussion about a wide variety of technical and commercial topics relevant to their work and hopefully have a thoroughly enjoyable experience to inspire them into the future! All training days will be eligible for CPD certification.

A car damaged after a retaining wall failure in Baltimore

This is a different perspective on landslides than what I usually blog about on GeoPrac. This banking and insurance website blog post discusses what should and shouldn't be covered on a car owner's insurance policy. Several cars parked along the road were damaged after a retaining wall / slope failure in Baltimore last month. [Source: Read the blog post at Bankrate, Inc.. Image: CBS Baltimore]
