To keep the loose soils beneath a planned hospital from liquefying and damaging the foundations during the design earthquake, Hayward Baker stabilized the site by performing wet soil mixing. In addition, HB installed tie down soil anchors inside soil mix columns to counterbalance the building seismic uplift forces. The team worked tirelessly to balance safety and production with stringent design and QC requirements. Learn more on their website, www.haywardbaker.com

Kansas Geological Survey uses Geophysics to Find Border Tunnels
The Kansas Geological Survey has some interesting seismic equipment that they have used on behalf of the U.S. Department of Homeland Security to look for drug tunnels along the US-Mexico border. I’ve never seen anything quite like this. The sensors all appear to be placed within an old fire hose and mounted onto a Bobcat Toolcat utility machine. On the front of the vehicle is a cyllinder with a 60-lb weight that gets dropped. Read on. (Photo by Richard Gwin, LJWorld.com)
