Geo-Florida 2010 Papers posted
By Robert Thompson, on May 11th, 2010

Papers by Dan, Steve, and Tim that were included in the GeoFlorida 2010 conference have been uploaded to our Publications page. Dan and Steve co-authored a paper on the test program of the base grouted drilled shafts for the Audubon Bridge. Tim co-authored a paper with Willie NeSmith of Berkel and Company Contractors, Inc. on plate load testing of displacement grout columns. Dan was also a co-author with several others on a paper on jet grouting for improved pile lateral capacity.
