The aim of this study is to compile new data from existing projects to identify the impact on the soil from the pile installation method and its influence on bearing capacity. These results will serve to analyze whether the current design methods used in pile design are adequate. The final deliverable will include recommendations to facilitate the design of vibratory driven piles. Several committee members have provided data from various projects. The committee held its specialty seminar August 7-8, 2014, at the Westchester Marriott Hotel in Tarrytown, N.Y. The seminar focused on planning, environmental issues, contract delivery and selection process, design phase testing, procurement process, foundation design, bridge design and bridge construction aspects of the New Tappan COMMITTEE CHAIR GERALD VERBEEK Testing and Evaluation Committee The Testing and Evaluation Committee is grateful for the two years of service provided by outgoing chair Don Robertson. In 2015, the committee will continue to meet by conference call the last Tuesday of each month at 2:00 p.m. Eastern Time, and any DFI member interested in testing and evaluation of deep foundations is welcome to join. Initially, the committee’s focus will be creating a webinar on one of the foundation testing methods. It would be aimed at educating students and non-practitioners on performing the test method, analyzing the test data, and weighing the appli- cations and limitations of the method. The committee will also continue other activities including a review of the DFI Lexicon and Glossary and the QA/QC procedures for foundation testing that were developed as part of FHWA’s SHRP2 for various geotechnical technologies (www.geotechtools.org). Zee Bridge. The Ben C. Gerwick Award for Innovation in Design and Construction of Marine Foundations was presented at the seminar to Dr. Grey Mul l ins and hi s research team from the University of Florida. A boat tour of the site was held at the close of the seminar. The Marine Foundations Committee is supporting the IFCEE Conference in San Antonio. Committee Chair Rick Ellman is the chair for the wind energy foundations session. The committee helped peer-review six papers to be presented at the conference. The 2015 Ben C. Gerwick Award for Innovation in Design and Construction of Marine Foundations will be presented at the conference to Proserve Ltd for the development of the Proserve Grout Bag. The committee is also supporting SuperPile 2015 by submitting a paper by committee member Greg Piazza of Mueser Rutledge Consulting Engineers. The next committee meeting will be held at SuperPile 2015 in Kissimmee, Fla., May 6-8, 2015 (see page 26). All are welcome to attend.
