Soil Mixing Committee Chair: Dennis Boehm Hayward Baker [email protected] Trustee Liaison: Dr. K.S. Rama Krishna DFI of India [email protected] • Committee was primary technical supporting group for Deep Mixing 2015 Symposium • Preparing Soil Mixing Guidelines overviewing constructability and feasibility of deep mixing in North America • Preparing technical seminar for 2016 • Conducting laboratory study of strength and deformation properties of soil-cement mixtures, and appropriate laboratory procedures (Researcher: Prof. George Filz, Virginia Tech) • Preparing white paper on QC/QA issues for deep mixing Subsurface Characterization for Deep Foundations Chair: Victor Donald, P.E. Terracon [email protected] Trustee Liaison: Jim Morrison ILF Consultants [email protected] • Planning activities to raise level of awareness of need for and economic benefits of accurate and effective subsurface characterization information. Activities under consideration include: - General public relations campaign to create public awareness of the benefits - Collaboration with liaisons to consider an award or certification system (similar to LEED Certification) that promotes and recognizes the use of proper subsurface characterization techniques • Active liaisons with AASHTO, ACI, ASTM, FHWA, GeoInstitute, TRB and USACE • Influencing foundation contracting by reviewing and commenting on new geotechnical contracts developed by the American Institute of Architects • Developing liaison with DFI of India task force on geotechnical investigation Sustainability Chair: Carlos Englert, P.E. Schnabel Engineering [email protected] Trustee Liaison: Marine Lasne Entrepose Contracting [email protected] • Promoting EFFC-DFI Carbon Calculator, a standardized spreadsheet tool for calculating equivalent carbon volumes for deep foundations methods. • Encouraging use of committee prepared project data templates to build international carbon databank for foundation projects • Charging committees with defining sustainable aspects of their deep foundation techniques (slurry walls, driven piles, ground improvement, etc.) • Providing a presentation on sustainability in each DFI topical seminar • Developing liaison network with ACI; ASCE-SEI Sustainability Committee; California Committees (SEAOSC, SEAONC, SEAOSD, SEAOCC); U.S. Green Building Council; FHWA, and USACE Testing and Evaluation Committee Chair: Gerald Verbeek Allnamics Pile Testing Experts BV [email protected] Trustee Liaison: Bernie Hertlein, FACI GEI Consultants [email protected] • Preparing series of videos on foundation testing methods and data analysis for nonpractitioners, starting with a video on static load testing • Reviewing SHRP2 GeoTechTools.org website for foundation testing requirements to assess the extent and consistency of use of deep foundations monitoring and testing methods by State DOTs • Preparing overview of instrumentation tools and use • Reviewing DFI Lexicon to assess correctness and completeness of terms and definitions • Defined liaisons with AASHTO, ACI, ASTM, CGS, GeoInstitute, PDCA, TRB DEEP FOUNDATIONS • NOV/DEC 2015 • 109
