Hayward Baker (HB) recently began work on a $9.1 million ground improvement contract for the K-10 South Lawrence Trafficway (SLT) Project located in Lawrence, Kan. as a subcontractor to Emery Sapp & Sons, Inc. The project provides a significantly improved transportation infrastructure for the state, making it a top priority for the Kansas Department of Transportation (KDOT).
Current construction will complete the southern K-10 bypass from its intersection with US 59 to the existing K-10 [...]
Norcross, GA – August, 2014 – Dataforensics proud to announce a major update to its Rapid CPT Software.
The new version of Rapid CPT (version 4.2) drastically improves performance. Depending on the dataset, the processing time is typically reduced by 80-95%. This is particularly important for customers with large datasets consisting of a hundred or more soundings where processing time previously took 3-4 hours which has been reduced to 10-15 minutes. Additionally, a new Cloud based [...]
The giant straddle cranes that load and unload cargo from the container ships at the Port of Oakland apply a fairly concentrated load along their wheel path. Over time, the wheel path area has settled, creating a hazard to crane operators, cargo, and all port workers. URETEK ICR and their affiliate EagleLIFT were called in to use their patented geopolymer technology to stabilize and lift the subgrade, restoring the wheel path to it's original elevation. Check out the video! URETEK ICR is a [...]
What are the top geotechnical engineering schools in the United States? I don't know how accurate or scientific this list is, but a quick glance tells me they definitely got many of the most well-known programs. Their list was based on the top Civil Engineering Programs (according to US News and World Report) that also offer geotechnical engineering programs. I doubt the person who compiled this knows much about geotech. But if you are a student researching where to go get a MS in geotech, this [...]
Early Sunday morning, a 6.0 Magnitude earthquake struck near Napa California lasting 10 to 20 seconds, sending 120 people to the hospital and damaging buildings, breaking water mains, disrupting power distribution, and breaking gas lines and causing fires. The earthquake was the largest to strike the Bay Area since the 1989 Loma Prieta Earthquake. I will provide more info relevant to geoengineers in the coming days. If you find any interesting info, leave a comment, or email or tweet it to me [...]
MIT Emeritus Professor Charles C. (Chuck) Ladd passed away on August 4 according to a post on the ASCE Geotechnical Engineering Group. Professor Ladd was a legend in the geotechnical engineering community, and among his many awards were the prestigious Croes Medal, the Norman Medal, and the Terzaghi Lecture Award. He was also a member of the National Academy of Engineering. You can find Professor Ladd's obituary at the Boston Globe. [Source: LinkedIn - ASCE Geotechnical Engineering Group. [...]
There hasn’t been much to report recently for the Alaskan Way Viaduct Tunnel Project in Seattle. As you probably know, Bertha has not advanced since about December of 2013 after drilling through an abandoned steel well casing left over from engineering studies. Whether it was the casing or boulders, or something else that damaged the seals around the giant TBM’s cutterhead, they have some major repair planned. If you like, feel free to read more about what happened with [...]

Esri announced earlier this summer that they were making over 175,000 historical maps from the USGS available online. The maps are available to anyone to view online using their web map viewer. Or ArcGIS online subscribers can have access to high-resolution geo-referenced raster images for use in their ArcGIS projects and web mapping projects. Very cool!

Professor Petley, the author of the Landslide Blog, has an interesting discussion about a controversy in the geoengineering / geology community regarding the Oso landslide in Washington State. The Geotechnical Engineering Extreme Events Reconaissance (or GEER) report was recently issued for the OSO landslide. But USGS scientists have a different theory about the event. Both the GEER committee and the USGS agree that the Oso landslide was a two-fold failure event. But the difference in [...]
According to the Landslide Blog, this rockfall video was taken in Maoxian County in Sichuan Province of China on or around July 17, 2014. It shows a very dangerous rockfall event with people running from their cars. In one scene you can even see someone being struck by a rock and knocked over. The person is later able to walk away with assistance. Towards the end of the video, even the windshield of the videographer is struck by a smaller rock and cracked. Very dramatic and very scary video!
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.

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 [...]
ASFE has been a fixture in the geoprofession since its inception in 1969. They are officially changing their name to the Geoprofessional Business Association to more accurately reflect what their role and mission is.

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 [...]
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
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.

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 [...]
