In an open letter to geotechnical engineers and agencies that specify geosynthetics on their projects, the Geosynthetics Manufacturers Association (GMA) has requested that specifiers use the correct standards when referring material properties of geotextiles and other geosynthetics. For example, they refer to two standards that are now out of date, The Mullen Burst Strength and the Puncture Test which were both originally designed for paper. The correct standard is the Static (CBR) Puncture ASTM D6241. See the entire letter on Geosyntheticsmagazine.com. (Photo of Geotextiles from Nilex.com)
Foundation Industry Launches Standardized Open Source Tool to Compare the Sustainability of Different Foundation Techniques
Hawthorne, NJ (May 1, 2013): The European Federation of Foundation Contractors (EFFC) and the Deep Foundations Institute (DFI) are urging the geotechnical sector to make immediate use of their jointly-developed, pioneering carbon calculator tool, the Geotechnical Carbon Calculator.
Developed using internationally recognized standards, the Geotechnical Carbon Calculator is believed to be one of the construction industry’s first standardized and collaboratively produced carbon calculator tools at the European and international level.
Carbon measurement is at the core of the construction industry’s approach to sustainability. The Geotechnical Carbon Calculator uses a standardized emission factors database to make the analysis of the carbon footprint of a foundation project consistent and comparable across the foundation industry.

Geotechnical Engineering Challenges of British Columbia’s Sea-to-Sky Highway, gateway to the 2010 Vancouver Olympic Games
I don’t know about you, but I’ve been enjoying watching the 2010 Olympic Winter games over the past few days. If you have, you know that Whistler is the venue for many of the sports including alpine skiing, luge, skeleton, bobsled, ski jumping, biathlon and cross-country skiing among others. The Whistler area is located about 50-miles or so North of Vancouver. In order to get to Whistler, you need to drive along Highway 99, better known as the Sea-to-Sky Highway. This highway has a long history of geotechnical problems, including some significant structurally controlled rockslides and landslides. In the years leading up to these Olympic Games a fair amount of work was done on the highway with some significant geotechnical innovations.
