Dan and Steve co-authored an article in the Fall 2011 issue of Deep Foundations (from DFI) that covered the foundations for the recently completed record-setting Audubon Bridge in Louisiana.  Dan and Steve cover not only the shaft testing, design, and construction, but also the unique cofferdam used for the tower foundations.  I recently highlighted an article by Sereno Brown, P.E. of Flatiron that covered the design and installation of the cofferdam in detail.
