Structural Systems Inc. recently completed tieback anchor projects at two sites along the coast of Hawaii. Failing retaining walls were stabilized using a total of 93 anchors ranging in length from 50 to 65 feet. The access was difficult, and the anchors were installed from a custom made platform attached to an excavator using a TEI Rock Drill that allowed wireless of the drill for the most challenging locations.

Robert Thompson of Dan Brown and Associates has posted a wrapup of the 2008 ADSC Faculty Workshop. They had 20 Civil Engineering faculty attend the event. The field demonstration day was hosted by DBA at the Trial’s Training Center in Sequatchie, Tennessee. Apparently that site is Dan’s hobby. Read more about the workshop itself and also read Robert’s post about the field demonstration day including photos. In the photo at right (Robert Thompson, DBA) you can see the Statnamic test setup for a drilled shaft. A little more about the event:
