Dr. Steve Dapp…in Taiwan!

During a recent trip to Taiwan, Steve had the opportunity to participate in a lecture on base grouted drilled shaft foundations.  He was invited to speak at a meeting of the Chinese Taipei Geotechnical Society (CTGS), also known as the Taiwan Geotechnical Society (TGS), by Dr. Prof. San-Shyan, Lin, National Taiwan Ocean University (current president of TGS).  The meeting was held at the National Taiwan University of Science and Technology.

His visit on 21 June 2011 was noted in the August 2011 issue (Volume 5, No. 4, p82) of the ISSMGE Bulletin.  During his lecture, Steve talked about the experiences of DBA with base grouting drilled shafts at the Audubon Bridge and the Huey P. Long Bridge on the Mississippi River in Louisiana.  Steve said that base grouting has become a very common technology in Taiwan for high rise structures supported on drilled shafts.

The meeting is noted here on the TGS site.
