The project is expected to be completed in December 2015. Members are encouraged to submit additional load test data for inclusion in the database. Please forward relevant information to Professor Lemnitzer at [email protected]. The committee is also co-funding a European Federation of Foundation Con- tractor (EFFC) project to develop guidance to better evaluate the properties of tremie concrete for use in deep foundations. The work was launched in 2014 by EFFC contractor members to define a practical testing protocol for characterizing fresh concrete that ensures reliable performance in deep drilled shafts and diaphragm walls. This project is also being funded by the DFI Committee Project Fund, and the original project scope was tailored to include a North American perspective. Peter Faust from Malcolm Drilling (lead), Dan Brown from Dan Brown and Associates, Ray Fassett from Condon Johnson Associates, Professor Erik Loehr from University of Missouri-Columbia and George Tamaro, retired, Mueser Rutledge Consulting Engineers, will provide technical support. This effort is also being supported by the DFI Slurry Wall Committee. The scope of work includes field and laboratory testing of concrete mixes, and the committee is COMMITTEE CHAIR GARY SEIDER The Helical Piles and Tiebacks Committee continues to be active; working on several projects directed toward advancing the practice and understanding of helical piles and tiebacks. Two of our three model specifications Helical Piles and Tiebacks Committee The 2015 Helical have been published. The Helical Anchor Specification was completed in July 2014 and the Helical Pile Specification was completed in February 2015. The publications are available through the DFI website. Work remains on a model specification for helical soil nails. A subcommittee consisting of David Bruce, Mark Bryant, Gary Seider and Wayne Thompson meet regularly with Mary Ellen Large to work on the Helical Soil Nail Specification. Piles and Tiebacks Committee Specialty Seminar will be held September 10, 2015, at the Newark Liberty International Airport Marriott in Newark, N.J. The seminar theme is “Helical Piles for Disaster Relief.” Presentations will cover proper design, application and installation of helical piles for disaster relief. Topics specific to the damage sustained from Hurricane Sandy will be presented. Task I of the Seismic Research project is underway thanks to the work of Bill Bonekemper and the generous donations of several DFI members. The work is being seeking North American project sites and sponsorships for the work. Please contact Mary Ellen Large at [email protected] for more details. DFI is leading an initiative to enhance the presence of the foundation engineering industry at next year’s International Bridge Conference (IBC), June 6-10, 2016, at the Gaylord National Resort & Convention Center, National Harbor, Md. Bubba Knight of Loadtest USA is leading this effort. The IBC is attended by hundreds of state and federal public and private owners, contractors and structural engineers involved in bridge design and construction. The Drilled Shaft Committee is working with the Driven Pile Committee to present a session on challenging foundation projects that highlight the benefits of collaboration between the foundation engineers, bridge designers and contractors. The benefits of shared expertise and cooperation have been demonstrated on several bridge projects as manifest by improved economy, schedule and constructability. A dedicated section of the exhibit hall is being pursued to show- case foundation-related services and products. We hope you can join us. Please contact Bubba at [email protected] if you have interest in participating.
