FHWA NHI Manual: Drilled Shafts Construction Procedures and LRFD Design Methods
The FHWA has released for download a comprehensive update to the 1999 O’Neil and Reese manual “Drilled Shafts: Construction Procedures and Design Methods”, lovingly referred to in the industry as the “Brown Book” or the “Drilled Shaft Bible”. This 2010 manual from the National Highway Institute (NHI) of the FHWA is entitled “Drilled Shafts: Construction Procedures Procedures and LRFD Design Methods” and was authored by Dan A. Brown, Ph.D, P.E. of Dan Brown and Associates, John P. Turner, Ph.D, P.E. of the University of Wyoming, and Raymond J. Castelli, P.E. From an FHWA Memo on the manual:
Distributed with this memorandum is the publication entitled "Drilled Shafts: Construction Procedures and LRFD Design Methods" (FHWA-NHI-10-016). This manual is the reference text used for the National Highway Institute (NHI) course numbered 132014 on Drilled Shafts. The publication will become the tenth in the series of geotechnical engineering guidelines called "Geotechnical Engineering Circulars." Geotechnical Engineering Circular (GEC) No. 10 is prepared as a significant revision and update to "Drilled Shafts: Construction Procedures and Design Methods" (FHWA IF-99-025), and reflects the standard of practice for the design, construction and inspection of these features. The guidance is developed following Load and Resistance Factor Design (LRFD) procedures and will enable engineers to identify and evaluate technical feasibility and potential applications. The text is developed with a sufficiently broad scope to be of value to a wide range of transportation specialists responsible for assisting with selection, design, development of materials specifications, construction monitoring, and contracting methods for Drilled Shafts.

Dr. Jorj O. Osterberg – In Memorium
Dr. Jorj O. Osterberg, inventor of the Osterberg Cell or "O-Cell" used for drilled shaft load tests has passed away at the age of 93. According to the Association of Drilled Shaft Contractors or ADSC, he died peacefully in his sleep on June 1, 2008. The geotechnical community has lost a truly legendary figure in our field.
Osterberg held degrees from Columbia, Harvard and Cornell Universities. He was a Professor Emeritus from Northwestern University. He was a former Chairman of the Soil Mechanics and Foundation Division of the ASCE, an Honorary Member of ASCE, and a member of the National Academy of Engineering. He delivered the Terzaghi Lecture in 1985, and later received the Terzaghi Award. He was one of the last surviving founding members of the International Society of Soil Mechanics and Foundation Engineering. He received the Distinguished Service Award from the Deep Foundations Institute and the Lifetime Achievement Award from the Association of Drilled Shaft Contractors.
