• Developing a workshop on Seismic and Lateral Loads Design Guide published by DFI in 2012. Planning to roll out the Workshops in the spring of 2018. Slurry Wall Committee Chair: Giovanni Bonita, Ph.D., P.E., P.G., GEI Consultants, [email protected] Trustee Liaison: Stefano Valagussa, TREVIICOS Corporation, [email protected] • Finalizing the Guide to Selection of Cutoff Methods. • Collaborated with the organizing st committee of the DFI 41 Annual Conference on the Seepage Control & Remediation track. • Working with members of the Sustainability Committee to identify sustainable aspects of slurry wall technologies and quantify carbon emissions for slurry walls case histories using carbon calculator. • Initiating development of a PowerPoint presentation on slurry wall construction. • Finalizing consensus guidelines for design and detailing of reinforced concrete diaphragm walls used as permanent basement walls in regions of high seismicity, including practical and economical design recommen- dations and proposals for influencing relevant building code provisions. • Interest in connecting technical committee members with technical members from tunneling societies (NATC, RETC). • Discussing specification for slurries for deep foundations. Subsurface Characterization for Deep Foundations Committee Chair: Victor Donald, P.E., Terracon, [email protected] Trustee Liaison: Conrad Felice, Ph.D., P.E., ILF Consultants, [email protected] • Planning activities to raise the level of awareness of the need for and economic benefits of accurate and effective subsurface characterization information. Activities under consideration include: o General public relations campaign to create public awareness of the benefits. 114 • DEEP FOUNDATIONS • NOV/DEC 2016 Soil Mixing Committee Chair: David Miller, P.E., Consultant, [email protected] (Immediate Past Chair: Dennis Boehm, Hayward Baker, [email protected]) Trustee Liaison: Marty Taube, P.E., P.G., Menard, [email protected] • Published DFI Soil Mixing Guidelines, which provides an overview of constructability and feasibility of deep mixing in North America. • Conducting a laboratory study of strength and deformation properties of soil-cement mixtures, and appropriate laboratory procedures (Researcher: Prof. George Filz, Virginia Tech). • Preparing a white paper on QC/QA issues for deep mixing. • Gauging the industry for market size by surveying industry members and cement associations. Sustainability Committee Chair: Carlos Englert, Ph.D., P.E., Schnabel Engineering, [email protected] Trustee Liaison: Marine Lasne, Entrepose Contracting, [email protected] • Developing and conducting a research plan to gather information on the current status and future of sustainability legislation and regulatory initiatives that includes: o Developing a contact list of large private and public owners, and regulatory agencies such as FHWA, USACE, IGCC, U.S. Green Building Council, AIA, ASCE, etc. o Preparing a presentation to approach regulatory agencies and owners. o Contacting and meeting with regulatory agencies and owners. o Preparing a white paper reporting the findings of the study. • Assist other committees on incorporating sustainable practices when preparing guide specifications, guidance documents, etc. o Collaboration with liaisons from AASHTO, ACI, ASTM, FHWA, GBA (formerly ASFE), G-I, TRB and USACE to consider an award or certification system (similar to LEED Certification) that promotes and recognizes the use of proper subsurface characterization techniques. • Influencing foundation contracting by reviewing and commenting on new geotechnical contracts developed by the American Institute of Architects. • Developing liaison with the DFI of India task force on geotechnical investigation.
