The May/June 2011 issue of ASCE’s Geo-Strata focuses on bridge geotechnics. Dan contributed an article to this issue summarizing key constructability considerations for bridge drilled shaft designers. Specifically, the article focuses on fresh concrete properties and reinforcement design. Discussion of self consolidating concrete (SCC) and column-shaft connections is also included. The article has been added to our publications page and is available through the link above. Additional details related to bridge drilled shaft constructability can be found in the 2010 FHWA Drilled Shaft Manual here.
