Video: DeWind One-Pass Trenching - Hill AFB Contamination Project PDF Print E-mail
Written by Randy Post   
Sunday, 17 April 2016 22:21

This project video seems a few years old, but it's relatively new on YouTube and it's a fantastic case study of the slick method of installing groundwater interception trenches using DeWind's remarkable one-pass trenching technology. Hill Air Force Base in Utah had been using jet fuel ignited on a mock aircraft to train firefighters. The jet fuel had leached into the soil and was reaching the shallow aquifer. The DeWind technology was used to install a drainage trench to intercept the contaminated groundwater and pump it out for treatment before it reached the aquifer. This approach was several million dollars less costly than other alternatives they looked at. Project staff considered this method more likely to intercept the contamination than discrete wells spaced along the same alignment. [Source: DeWind YouTube. Image: YouTube]

First of the 67 7.8m diameter, 82m long monopiles for Veja Mate offshore wind farm roll out

Check out this massive pile foundation for a wind turbine at the 402MW Veja Mate offshore wind farm. It weighs over 1,300 tons (2,866 kips) and is 7.8 meters in diameter (25.5 ft) and 82.2 meters long (270 feet). The wind farm will consist of a total of 67 6MW turbines founded on giant monopiles like this. According to Offshore Wind, the Veja Mate OWF is located 95 km northwest from the island of Borkum in the German North Sea. When fully operational in 2018, the farm will produce over 1.6 TWh of electricity annually for 400,000 households in Germany. [Source: Offshore Wind. Image: Offshorewind.biz]

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]

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.
