Owners, contractors and engineers will share their perspective and presentations on new and recent tech- niques, designs and case histories. To register, go to www.regonline.com/marine. COMMITTEE CHAIR JON BENNETT Micropile Committee Congratulations to the ADSC-DFI Micro- pile Committee and the ADSC Anchored Earth Retention (AER) Committee who presented a very successful seminar in Salt Lake City in March. The event attracted over 200 attendees and 28 exhibitors. The event was chaired by Tom Hurley (Nichol- son Construction), supported by DFI- ADSC Micropile Committee Co-Chairs, Jon Bennett (Brayman Construction) and Greg Sullivan (Subsurface Construction Company LLC) and ASCE AER Chair Dan Thome (Nicholson Construction). The participants enjoyed two days of presen- tations and discussion on anchored earth retention and micropile topics. Thank you to Atlas Copco for sponsoring the atten- dance of Matt Rigby, a civil engineering student from the University of Phoenix. Bennett presented the state of the practice of geotechnical and structural design of micropiles, and Alan Macnab (Macnab Consultants) presented the state of practice for design and construction for earth retention. These overviews were supple- mented with presentations on selection of appropriate techniques, monitoring, testing, quality control and assurance, and project case histories. Thank you to all of the organizers, speakers and exhibitors. DFI developed an Energy Piles Working Group as a subcommittee of the Sustainability Committee. This group formed after the DFI-Virginia Energy Piles workshop in Arlington, Va., in 2010. DFI members involved in the working group have contributed practical input to the university research at Virginia Tech by providing field testing sites, equipment, dr i l l ing services , mater ial s and COMMITTEE CHAIR GERRY HOULAHAN Marine Foundations Committee instrumentation. We will be exploring new ways to collaborate with other groups to advance the understanding and use of energy foundations. Please contact Mary Ellen Bruce at [email protected] for more information and to become involved in the group’s activities.
