The effort was led by Bob Simpson of Loadtest USA and the presentation is being narrated by Mary Ellen Bruce Large of DFI. If this first tutorial is well received, the committee will proceed with presentations on other testing methods, so your feedback would be very much appreciated. Another major activity in recent months was the preparation of two proposals for project funding. We suggested a summary compendium (with a thorough biblio- graphy) of existing but difficult-to-find research on quantifying the scale effects associated with load testing undersized deep foundation elements relative to their full- scale production counterparts. A second proposal dealt with research into test and COMMITTEE CHAIR RICK ELLMAN, P.E. Marine Foundations Committee The Marine Foundations Committee is pleased to announce that the DFI Commit- tee Project Fund Research Project, “Compar- ison of Impact Versus Vibratory Driven Piles: With a Focus on Soil-Structure Interaction,” by Dr. Paul Doherty of Gavin and Doherty GeoSolutions, has been released in its final version. This project was jointly endorsed by the Driven Pile Committee. The report is avail- able for download from the Marine Founda- tions Committee webpage and on the Committee Project Fund page at www.dfi.org. Currently, the committee has been looking at other topics for DFI-funded research, including studying the use of geo- polymer concrete for marine structures. This topic was discussed at our last commit- tee meeting in Oakland in October 2015. The subcommittee selected the recipient for the 2016 Ben C. Gerwick Award for Innovation in Design and Construction of Marine Foundations. The award was given at SuperPile ’16 in Chicago in June to the Traylor-Massman- Weeks Joint Venture. The group was recog- nized for its development and successful implementation of an Assembly Line Con- struction Approach for construction of the Inner Harbor Navigation Canal (IHNC) Storm Surge Barrier for the City of New Orleans. Other committee activities include exploring future specialty seminar oppor- tunities and looking at possible updates to Deep Marine Foundations — A Perspective on the Design and Construction of Deep Marine Foundations (originally published in 2009). Those interested in the Marine Foundations Committee should contact [email protected]. reaction pile spacing requirements for axial load tests to determine the influence of reaction piles on the test pile. These proposals were coordinated by Bob Simpson of Loadtest USA and David Tara of Thurber Engineeri- ng, respectively, and while they were not selected for funding in 2016, the committee is always interested in feedback on the need of research on these topics. This will help us decide whether to resubmit similar proposals later this year for funding in 2017. The committee continues to meet every last Wednesday of the month for an hour conference call. Committee members and other DFI members who are not yet involved are encouraged to join these calls and actively support our efforts associated with the testing and evaluation of deep foundations.
