Presentations will include history, definitions, construction, different wall methodologies, QC/QA, sustainability, challenges and mitigation, alternative tech- nologies, equipment and example projects. Committee members continue to work closely with members of the Sustainability Committee to promote sustainable aspects of slurry wall technologies. The group developed a template for project history information for input into the EFFC-DFI carbon calculator (www.geotechnical carboncalculator.com). The committee hopes to enter real case history data into the calculator to develop a bank of carbon analyses for slurry wall projects. The com- mittee is also promoting other sustainable aspects of slurry wall technologies including lean design, value engineering, and materials and work flow optimization. The committee’s next seminar is planned for June 2015 in conjunction with the Rapid Excavation and Tunneling Conference (RETC) in New Orleans. This one-day seminar will be a workshop focusing on cutoff walls and trenches, which would be an interesting topic for the Gulf Coast region. The committee is working to connect members with technical representatives from RETC to encourage joint participation in these aligned events. I have enjoyed being chair of the Slurry Wall Committee, and will be pleased to pass the gavel to long-standing committee member, Dr. Giovanni Bonita, P.E., P.G., (GEI Consultants, Inc.) at the DFI Annual Conference in Atlanta in October 2014. I appreciate the support and dedication of the committee members over the past few years. I know that the committee will be in good hands with Giovanni’s lead and I wish him good luck picking the fruits on all the seeds we left him to water. COMMITTEE CHAIR DONALD ROBERTSON The Testing and Evaluation Committee is meeting monthly via conference call to work on the various activities listed in our annual plan. These conference calls take place the last Tuesday of each month, and all interested parties are more than wel- come. The committee again participated in SuperPile ’14, which was held in Cam- bridge, Mass., in June. Les Chernauskas (Geosciences Testing & Research Inc.), one of our committee members, led that effort as chair of the planning committee. With this successful event behind us, we are focused on the joint PDCA/DFI symposium “Driven Pile: A Foundation for the 21st Century.” This seminar will take place in Austin, Texas on September 9, 2014. See www.dfi.org for more information. Another goal of the committee is to improve communication with the Moni- toring Committee of DFI Europe. Repre- sentatives from both committees met in Sweden during the DFI-EFFC International Conference on Pi l ing and Deep Foundations. We will provide more details on how the two committees will move forward to share information and work together in a future issue of the magazine. Testing and Evaluation Committee The committee began working on the review of the QA/QC write-ups for the various technologies covered in FHWA’s Geotech Tools website (www.geotechtools.org). This website was developed to make geotechnical solutions more accessible to public agencies in the U.S., and is a toolkit of geotechnical information to address all phases of decision making from planning through design and construction. The objectives of our review are to assess whether the testing and evaluation procedures posted for these technologies reflect current industry standards and to suggest improvements where appropriate. If you are interested in these activities or in testing and evaluation topics in general, feel free to contact Don Robertson or Gerald Verbeek, vice chair (Allnamics Pile Testing Experts BV), to learn more about the committee. If you are interested in becoming a member of the committee, contact DFI headquarters at [email protected]. Written by Gerald Verbeek, vice chair.
