DFI Forms New DFI Technical Committee: Subsurface Characterization for Deep Foundations
Hawthorne, NJ (May 28, 2014): DFI announces the formation of a new, 16th technical committee focusing on site investigation for deep foundation design and construction.
The Subsurface Characterization for Deep Foundations Committee was formed to increase awareness of the importance of complete and competent site investigation in deep foundation practices. The specific goals of the committee will be defined by the committee members, however, initially the committee will discuss and define subsurface characterization needs from the point of view of the entire geotechnical/foundation industry. This will facilitate getting correct and comprehensive information to the end users (designers and contractors) and minimize change condition issues/debates. The committee will liaise with associated committees from other organizations and agencies to broaden the discussion within the engineering community. The objective is to find the common ground that allows the entire geotechnical industry and all project participants to minimize disagreement during construction, align expectations, and improve communication and understanding among related parties.

Landslide on Arizona SR 87 Closes Highway
On March 21, 2008 a landslide caused the closure of Arizona State Route 87 between Payson and Phoenix near mile post 224. So far there are no official estimates as to the size, but based on aerial photos, it appears to be at least 50,000 sq-ft in plan. The offset at the head scarps was approximately 2-meters (6.6-ft) according to AZGS Geologists on site. It appears to have been a rotational slide as the toe of the landslide heaved the southbound roadway up by as much as 1-meter (3.3 ft). There was an existing soil-nail retaining wall on the slope that was destroyed by the slide as well. Lateral deformations can be seen in photos of the median barrier and the roadway striping. The deformations extended into the northbound lanes as well. More photos and links after the break. (Photo by ADOT)
