The seminar is on August 1-3, 2016, at the Westin Denver International Airport in Denver, Colo. The seminar features two keynote Helical Piles and Tiebacks Specialty Seminar This year’s Helical Piles and Tiebacks Seminar is being held August 10-12 in Ontario, Calif. (outside Los Angeles). This 1.5-day seminar, preceded by committee meetings and exhibitor setup, offers technical presentations and case studies on helical piles and anchors in seismic and lateral load conditions, and a helical pile installation demonstration. Presentations provide an overview of the fundamentals of helical pile and helical tieback design and installation with topics specific to seismic and lateral loading, materials, and construction and testing procedures. Other topics include building codes related to the design of helical pile elements; case studies on the design and use of helical piles systems and helical tiebacks on new and retrofitted projects; helical pile and helical tieback performance studies; advance- ments and innovat ions in design, construction and equipment for helical piles and tiebacks; quality control and inspection; and practice-oriented research. presentations. “Introduction to Landslide Stabilization Design and Construction” by Professor Erik Loehr, P.E., of University of Missouri, Columbia, addresses design and use of deep foundations for slope stabilization and covers concepts of load transfer for deep foundations from moving soil, important failure modes and limit states that should be considered for design of deep foundations for slope stabilization, practical methods for prediction of foundation resistance, and consideration of structural resistance for deep foundations in slope stabilization applications. “Do’s and don’ts” for design of deep foundations for slope stabilization along with a brief case history comparing the predicted and measured resistance for drilled shafts are also included. The second keynote presentation, “Tieback and Soil Nail Design and Construction for Excavation Support and Landslide Stabilization,” is being made by Dr. Jesús Gómez, P.E., D. GE, of GEI Consultants. His presentation depicts several scenarios that the author has experienced frequently in practice, where Dr. Jesús Gómez, P.E., D. GE lack of attention to seemingly minor details during construction document develop- ment caused construction claims or stoppages. The presentation also discusses simple ways in which such problems could be avoided. The discussion is illustrated through actual case histories. In conjunction with S3, the Women in Deep Foundations (WiDF) Committee is hosting an evening lecture on Monday, August 1, led by Professor Shideh Dashti, assistant professor and the director of the geotechnical centrifuge facility at the University of Colorado. Her lecture is titled “Seismic Performance of Structures on Liquefied Ground and the Effectiveness of Mitigation Strategies.” The lecture will be held at HDR’s downtown Denver office, and there will be networking and refreshments preceding the lecture. There is no cost to attend the event, but registration is required. S3: Slopes, Slides and Stabilization Seminar DFI’s Deep Foundations for Landslides/ Slope Stabilization and Tiebacks & 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 Professor Erik Loehr, P.E. Seminars Being Planned Two specialty seminars are being planned for the fall. Soil Mixing and Micropiles: States of Practice for Design, Construc- tion and Quality, a two-day seminar, is being held in September in Orlando, Fla. The ACIP Piles Seminar, is a one-day event being held in November in Orange County, Calif. Stay tuned for details. DEEP FOUNDATIONS • MAY/JUNE 2016 • 61
