Poletto Arturo Ressi di Cervia Michael Wysockey COVER STORY: 10 Doyle Drive: Extreme Pile Installation The south access road to San Francisco’s Golden Gate Bridge is being replaced, and the foundation sits on an extremely vibration sensitive ravine site. Malcolm Drilling used the largest available oscillator to advance the casings without inducing ground vibration. SPECIALLANDMARKS :ISSUE This issue is devoted to technologies that changed the way the deep foundations industry is practiced. Some took years before widespread acceptance and most inspired new applications and advances in geotechnical engineering and construction. The Osterberg Cell Test: 45 Jack Hayes of Loadtest recounts the history of the O-cell test, a technology that transformed geotechnical engineering practice. Bengt Fellenius, consulting engineer, Fred Rhyner, MRCE, and Dan A. Brown, Dan A. Brown and Associates, contribute their views on this remarkable innovation. Dynamic Testing: a History: 53 PDI’s Gina Beim writes about dynamic pile testing and how this field has matured and improved over the years, since the 1971 tapered pipe pile installation at the Valley View Bridge in Ohio. Slurry Walls in the U.S.: 59 This landmark technology was used on a project of such enormous visibility and difficulty that its acceptance was accelerated in the U.S. Arturo Ressi, of Kiewit, was there, and describes the slurry wall at the World Trade Center in New York, and the method’s many subsequent developments and applications. Landmark Equipment: The Hydrofraise: 79 As slurry wall technology matured, the equipment evolved as well. Soletanche’s Hydrofraise was the first of a new generation of digging equipment that featured a cutting tool used for panel excavation with the spoil extracted by reverse circulation. Today there are several variations. Jet Grouting: 86 George K. Burke, Hayward Baker, a seasoned practitioner of jet grouting, has been a key figure in the growth and spread of this landmark technology. Jet grouting origi- nated in Japan, and Burke relates the history of its use worldwide. DFI ACTIVITIES: 17 The Distinguished Service Awardee, Bermingham Innovation Award, Student and Professor Paper Winners, Educational Trust Report, Regional Report from DFI Europe, DFI India Conference and the 2013 Annual Conference in Phoenix.
