2007 Hayward Baker Calendar Image

Geotechnical industry professionals are no doubt familiar with the awesome illustrations showing all manner of geotechnical construction methods and applications that are a unique part of Hayward Baker advertising and marketing. Without any fanfare, the iconic Hayward Baker calendar that features this artwork has celebrated a milestone of 20 years in 2016. It's so hard to explain to non-engineers what it is that geotechnical engineers do, all of our cool work is buried out of sight! This calendar is one of the best tools to show our expertise, it's a great service to our industry. On a personal note, I keep one hanging on my office door, and my 10-year old daughter even has one hanging on her wall, she says she wants to be an engineer when she grows up! Thanks Hayward Baker, and I look forward to another 20 years of great calendars! They have a great collection of 20 years of Hayward Baker calendar images over on their Facebook Page, check it out.

SPT Analyzer by Pile Dynamics

Pile Dynamics has updated their SPT Analyzer system of hardware and software used to calibrate hammers used for the geotechnical engineer's bread and butter - the standard penetration test or SPT. The hardware itself has been updated with a multi-touch interface, new color scheme options, and 'Smart Sensor' technology that automatically reads the rod instrumentation so that sensor calibration and other information is automatically read by the SPT analyzer. The software to process the data has been completely re-written and the output is now more customizable. [Source: Read more about the latest updates in Pile Buck Magazine.

Bertha's scheduled maintenance stop

The Bertha tunnel boring machine has resumed chewing away beneath Seattle after a 'suspension for cause' order from WSDOT shut it down in January following two safety incidents. The BTM began tunneling with some conditions in place late in February, and those conditions were lifted when the demonstration period ended on March 7. Bertha has now reached her next scheduled maintenance stop, having tunneled a total of 1,560 feet. [Source: WSDOT Alaskan Way Viaduct Replacement Project Page. Image: WSDOT]

Learn rock mechanics from a leading expert in the fieldThe following four short courses will be taught by Prof. Pinnaduwa Kulatilake in Tucson, Arizona in May 2016 as given below. Dr. Kulatilake was one of my professors at the University of Arizona during my geological engineering program.  If you have always been meaning to learn some rock mechanics to add to your geotechnical skill set, these courses would be a very good option.

  1. 2-Day course on Rock Fracture Geometry Characterization and Network Modeling in 3-D Including Validations (May 14-15)
  2. 2-Day Course on Deterministic and Probabilistic Rock Slope Stability Analyses (May 16-17)
  3. 2-Day Course on Deterministic and Probabilistic Block Theory & Applications for Surface and Underground Rock Excavations (May 18-19)
  4. 1-Day Course on Measurement and Quantification of Joint Roughness, Normal & Shear Deformations, Peak Shear Strength, Aperture and Fluid Flow through Single Joints (May 20)

This is some very interesting first-person video of a landslide near Elk City, Idaho, complete with expletives. :) I can't say I blame the videographer, it's not every day you see a slope like that come down. Must have been quite an experience to be there! [Source: YouTube. Image: YouTube]

Rescue workers searching through the collapsed building in Taiwan

Taiwanese investigators have arrested the developer of a 17-story apartment building that collapsed in an earthquake at the beginning of the month. Approximately 40 people were killed when the building collapsed, there were only two other deaths in the entire city. The charges are suspicion of criminal business misconduct resulting in fatalities. Mainland China has been notorious for shoddy construction practices, and those practices have been blamed for the death of thousands in Sichuan Province during the 2008 earthquake.

Fugro geophysical vessel used for UXO detection

Fugro released their 2015 Fiscal Year results, and the headline is 'Strong cash flow in continuing challenging oil and gas market'. The Dutch company's biggest market sector is oil and gas, and they are forecasting continued challenges this year with over-supply. The numbers show a drop in revenue of 17 percent from 2014 to 2015. Among the ways they managed the downturn is to sell or lease back two of their geotechnical drilling vessels, but they are also focusing on growing other market sectors and opportunities in all geographic regions.

NYDOT Geotechnical Design Manual Cover

The New York DOT has been working on a geotechnical design manual (GDM) since at least 2012. It is a very detailed document that covers pretty much every possible geotechnical aspect of a transportation project. It would be a valuable resource for any geotechnical engineer. Some chapters are still marked draft, but I like their transparency about what has been officially approved by the DOT and what is still under review. [Source: Check out the GDM of the New York DOT.
