Dan leads team updating the FHWA Drilled Shaft Manual

Dan is leading a technical team that is updating the FHWA drilled shaft manual “Drilled Shafts: Construction Procedures and Design Methods”, FHWA Publication Number IF-99-025, by Dr. Michael W. O’ Neil, P.E. and Dr. Lyman C. Reese, P.E.. The manual was first published in 1988. An updated version was published in 1999. A new edition is now underway in order to incorporate advances in design and construction of drilled shaft foundations. The effort will include a comprehensive review and analysis of load test results from all over the country in a variety of soil and rock formations in order to review and modify the recommended design methodologies. The team of authors that has been assembled includes:

Dr. Dan Brown, P.E. – Auburn University and DBA

Dr. John Turner, P.E.University of Wyoming

Dr. Jim Long, P.E.University of Illinois (Urbana-Champaign)

Ray Castelli, P.E. – PB (Parsons Brinckerhoff)

The author team will be assisted by Dr. Tom Sandford, P.E. of the University of Maine as well as graduate and post-doc students at the various universities. The team will also rely on input from designers and contractors in the drilled shaft industry. PB (Parsons Brinckerhoff) is the contract administrator for the manual update project. Jeremy Hung, P.E. is the PB project manager. The revised manual is planned to be available sometime in 2008.
