PRESIDENT’S MESSAGE Adiós, Farewell W ell, it has been a LOT of fun, but my two-year term as DFI president has come to an end, and it is time to move on. I am leaving you in the more than capable hands of new president, Dan Brown. Dan and I are good friends and I know he will do an exceptional job. I want to thank Theresa Engler, Mary Ellen Large, Emilio Fandino and all of the DFI staff for their help and hard work during my tenure. Especially, Theresa. I don’t know how she keeps it all straight and gets it all done. She is amazing. I would also like to thank all of the trustees and committee chairs who do so much for the organization. Also, thanks to all of the members of the Committee Project Fund Review Committee who have done a lot of good work over the last several years judging the many research proposals that have been submitted. You know who you are! I also thank Byrl Williams and David Coleman for the excellent job that both have done shephe rding the DFI Educational Trust. It is incredible the amount of success that has been realized through their great work and how many students are benefitting. Well done! So, what lies ahead for DFI? Good stuff, I am sure. The Deep Foundations Institute has become one of the premier industry advocate groups in the country. With hard work and dedication by the great number of individuals mentioned above, and all of Guidelines for Soil Mixing DFI and the DFI Soil Mixing Committee have released Guidelines for Soil Mixing. The new 80- page publication provides an overview of the state of practice of Deep Mixing Methods (DMM) in North America as well as a guide specification for deep mixing work. The 80-page document focuses on constructability and feasi- bility considerations for deep mixing and addresses the following applications: earth retention; liquefaction mitigation; groundwater seepage control and containment isolation; bear- ing capacity improvement; deep foundations; DFI I ® F I N D I N G C OMMON G R O U N D ® Guidelines for Soil Mixing I mass stabilization and contamination contain- ment; embankment, levee and dam strength- ening and stabilization; and casing replacement. It is intended that this document provide a basic introduction to wet and dry DMM to enhance its adoption and application in North America. Guidelines for Soil Mixing is available on the Publications page at www.dfi.org. The cost is $30 for DFI members and $50 for nonmembers. Purchase of this publication includes a PDF of the full guide and an editable Word document of the Guide Specification. our members, DFI has become a strong voice for our industry. We offer such great opportunities to get involved in committee work concerning all facets of deep foundat ions works. Join a committee. Write and present a paper at the annual conference or teach a specialty seminar. Get involved! I will be hanging around as past president at the Trustee and Executive Committee meetings to do what I can to help Dan and Theresa. So my smiling face isn’t going completely away. Vaya con Dios! John Wolosick, P.E., D.GE President [email protected] intelligent, and taught his class with style. Every class was a first- rate learning experience. He had a lot of experience with piling and he shared it with his students. He would cruise into the classroom, one minute late, wearing aviation sunglasses and a Hawaiian shirt. (Tom was an aviation enthusiast who flew “With hard work and dedication by a great number of individuals, and all of our members, DFI has become a strong voice for our industry.” An additional note: M.T. Davisson, foundation engineer, died on September 9, 2016, at the age of 84. ‘Tom’ Davisson was a professor for decades at the University of Illinois, Urbana-Champaign. He was a pioneer in the driven pile industry and well known for his work in pile testing, especial ly the ‘Davisson Limi t ’ to determine the failure load on a pile during a load test. Tom won the DFI Distinguished Service Award (DSA) in 1990. I took CE 384 – Foundation Engi- neering from Tom in the fall of 1977. He was a bit of a maverick. He was highly his own twin-engine plane.) He carried only his copy of Soil Mechanics in Engineering Practice by Terzaghi and Peck, which he referred to as the ‘Bible.’ This was the ‘Old Testament.’ Peck Hanson and Thornburn Foundation Engineering was the ‘New Testament.’ He made good use of these books as required reading, and would verbally quiz us about the chapters. He left a big impression on me that led me to piling and deep foundations as a career. I will always remember that class and him. R.I.P. M.T. Davisson.
