Immediate past chair, Marty Taube, P.E., P.G., of Menard, joined the DFI Board of Trustees in January 2016. We thank him for his dedication and manage- ment of the committee, which was very active under his leadership. Blackburn is chief engineer in the central engineer- ing group of Hayward Baker (HBI), located in Hanover, Md. He is responsible for technical risk evaluation and management, project management and estimating sup- port, and implementation of new and complex tech- nologies within HBI. He has been the designer of record and project manager for several ground improvement projects, including vibro-replacement, aggregate piers, compaction grouting, jet grouting, rigid inclusions and deep soil mixing projects. Blackburn earned a B.A. in physics from Middlebury College, Vermont, and M.S. and Ph.D. degrees in civil engineering from Northwestern University, Illinois. He is a member of the Geo-Institute of the American Society of Civil Engineers (GI-ASCE) serving on technical committees at the national level. DFI’s 2016 Not-To-Be-Missed Seminars Helical Piles and Tiebacks Specialty Seminar This year’s Helical Piles and Tiebacks Seminar will take place in July in Los Angeles, Calif. The two-day seminar will offer technical presentations and case studies on helical piles and the current state of practice worldwide. The event will focus on the fundamentals of helical piles and helical tiebacks design and installation. Leading this event is Committee Chair Gary Seider, P.E., engineering manager of Chance Hubbell Power Systems. S3: Slopes, Slides and Stabilization Seminar DFI’s Deep Foundations for Landslides/Slope Stabilization and Tiebacks and Soil Nailing Committees are organizing this two-day event featuring lectures by industry experts on current technologies, key design concepts and case histories that illustrate effective application of deep foundations for stabilization of slopes and excavation support. The goal is to present recent and future projects that include challenging slope and landslide repairs and excavation support with deep foundation methods. The seminar will take place August 1-3, 2016, in Denver, Colo., at the Westin Denver International Airport. The chair for this event is Professor Vernon R. Schaefer, P.E., from Iowa State University. The Women in Deep Foundations Committee will host a fundraising reception during the seminar to raise money for DFI Educational Trust’s Women in Deep Foundations Fund and to promote the cause of supporting women in the profession. Since there are continual advancements in the use of various deep foundations technologies for slope stabilization and excavation support, the committee is considering making this a larger event hosted every two years to meet industry needs. Soil Mixing – The Evolution of an Industry Seminar Coming in September to Orlando, Fla., this one-day seminar will cover design, quality assur- ance and control, construction, applications and case histories for soil mixing projects. Lead- ing this event is Committee Chair Dennis W. Boehm, senior vice president with Hayward Baker.
