Ok, this video has so many safety issues going on, you can't even count them all. But it is darn funny! Just know that this public video on Facebook lets anyone comment on it, so be warned. [Source: Facebook. Image: Facebook]
Over the last 18 months Peter Keeton has been heading up a team at Keynetix to write British Standard and ASTM Standard compliant test definitions, laboratory worksheets and reports for KeyLAB. This work has now been included free of charge with the latest installer of KeyLAB and enables new users of the software to be operational much quicker than ever before.
Peter Keeton has over 40 years of experience working in and managing geotechnical laboratories for Soil Mechanics and was an influential member of the CEN European Standards working group on geotechnical testing. Over this time he has produced many versions of laboratory worksheets for each test.
“By including the latest versions of Peter’s work into the system we have already seen an increase in the number of customers who are running trials of KeyLAB” said Dr Roger Chandler, Keynetix Managing Director. “The out of the box value of KeyLAB has increased significantly with this work and many users are now adopting the system with the standard sheets and only need to modify them with their company logos and details.”

When your gypsum plant is capable of producing 900 million square feet of wall board every year, you can't afford to see your process shut down by settlement or problems with groundwater infiltrating or soil erosion beneath slabs and footings supporting your facilities. GeoPrac sponsor URETEK ICR responded to these problems at a LaFarge Gypsum Plant in Florida and stabilized the subgrade and sealed up joints using their geopolymer injection technique. Did I pique your curiosity? Watch the video below for more details, and check out the full blog post by URETEK ICR for more details.
Over the last three years Keynetix have redeveloped their software products to appeal to an international audience whilst increasing their visibility and sales outside of the UK. This strategy is working well and enquiries and interest are at an all-time high resulting in sales outside of the UK increasing by 300% over the last three years. This transformation was recognised by the UKTI when Keynetix reached the final of the UKTI Global Growth Awards in 2012.

GeoWall is a competition for geotechnical engineering students where they build model mechanically stabilized earth retaining walls (MSE walls). The walls are then tested with a series of design loads and their score is a function of how well the wall performs under loading and how efficient their design was. The competition was held at the 2014 Geo-Congress in Atlanta which is put on by the Geo-Institute of ASCE. Students from universities all around the U.S. participated in this fantastic event! Enjoy the video highlights!
7 years ago today, I wrote my first post for GeoPrac.net! It’s hard to believe I’ve been doing this for that long. I am grateful for all of the visitors, twitter followers, supporters, and of course sponsors that have made it possible for me to share high-quality news and articles for geoprofessionals. I look forward to another great 7 years.
Last year I highlighted a few of my favorite articles and blog posts. This year, I thought I would just go by the numbers to see what the most popular articles and posts have been over the years. Check it out.
WSDOT announced on Valentine's Day that the plan to repair the damaged Bertha TBM was not ready yet, as engineers from Hitachi Zosen, the machine's manufacturer, would need until the end of the month to have the plan ready. They did say maintenance would need to be done in front of the face, requiring the construction of a vertical shaft. It sounds like more work for STP JV team member Malcolm Drilling, and they may already have started on it. We'll keep you posted. [Source: WSDOT. Image: Seattle Times]
U.S. Forestry Service Saves Thousands with Use of TerraThane Geotechnical Foam by NCFI Polyurethanes at Seneca Rocks Discovery Center
MOUNT AIRY, NC— Seneca Rocks Discovery Center, the visitor's center for the eastern U.S.'s most popular rock-climbing destination located in Pendleton County, WV, had a growing problem common to concrete slab foundations: erosion of the soil beneath the slabs created voids that left areas of the center with uneven spots and settled anywhere from one-to three inches. That led to cracks in interior walls, uneven floors, and trip hazards for the thousands of visitors to the area's most popular scenic attraction. Seneca Rocks is a striking 900 ft peak that features over 375 mapped climbing routes varying in degree of difficulty from easier 5.0 to the hardest 5.13, and attracts climbers from around the world.

This retaining wall failure occurred in Kuala Lumpur, Malaysia in 2009. The failure was caught on video, albeit with a crappy camera phone. But it's well worth a look! Dave Petley of the Landslide Blog also tracked down an article on the original failure. It's the usual case of chicken or the egg. Did the water pipe failure cause the wall to fail, or did the wall fail and then cause the pipe to fail. Thanks to my colleague Bob Cummings of Saguaro Geoservices for sending this my way.
A 40 foot diameter sinkhole 30 feet deep opened up beneath the National Corvette Museum in Bowling Green, Kentucky, and swallowed 8 of the Corvettes on display. The museum's security company alerted the staff members that the motion sensors had gone off at about 5:40 am on February 12 in the 'SkyDome' portion of the museum, separate from the main building. The museum called in a structural engineer and some Karst sinkhole experts who used a remote controlled helicopter to get photos and video inside the sinkhole. See those videos below. The main museum will be open as usual tomorrow, but the SkyDome will be closed indefinitely. [Source: NYTimes.com. Image: National Corvette Museum via NYTimes.com]
