Digital Edition of Deep Foundations The companion electronic version of this issue is available on the home page of the DFI website at www.dfi.org. Past issues are archived in the Publications section. Corrections: An error appeared in the May/June issue in an article on the February ICOG meeting. On page 17, in the last paragraph in the middle column, the first sentence about the tunnel in Australia should have stated the following: “To facilitate structural remediation of the invert, engineers installed some 5,200 permanent ground anchors in the underlying Melbourne mudstone to tie down 160 panels over a 2 km (1.24 mi) length of the concrete invert, …” The 5,200 grouted anchors were not corroded and were the solution, not the problem. We regret the error, and a correct version of the article appears in the July/Aug issue, page 46. The July/Aug issue incorrectly stated on p.30 that Hal Hunt was the first president of DFI. Hunt was the first secretary of DFI, and later, the first executive director. DFI’s first president was Jack Dougherty. Both men were instrumental in founding DFI. Thanks to Bengt Fellenius for spotting this error. — Virginia Fairweather, Executive Editor Regular Features: President’s Message . . . . . . . . . . . . . . . . 5 Executive Director Update . . . . . . . . . . 7 Technical Committee Reports . . . . . . . 61 New Members. . . . . . . . . . . . . . . . . . 101 Calendar . . . . . . . . . . . . . . . . . . . . . . 102 Ad Index. . . . . . . . . . . . . . . . . . . . . . 102 COVER STORY: 10 The 2012 OPA Winner: The Route 9A Pedestrian Tunnel at the World Trade Center This tunnel is an underground connection between all of Lower Manhattan’s transit lines, the World Trade Center and the World Financial Center. This design and construc- tion team led by the Port Authority of New York and New Jersey overcame many geotechnical engineering obstacles near the site of former WTC-Twin Towers. TECHNICAL FEATURE: 53 Dynamic Pile Testing: A New Approach Dynamic testing for the prediction of axial pile capacity is now about 40 years old and is used worldwide. Goble Pile Test, Inc. has developed a new system, called “Pile Check,” that is easy to operate and determines and displays the pile capacity in real time for every hammer blow. The article, by George Goble, describes the device. O T N A S D I N N U S T O I F T U E P T E E D
