The calculator is a user- friendly, spreadsheet-based tool and associated database of standardized carbon factors that allow for standardized compari- son between different foundation technol- ogies and variations of quantities and materials for specific foundation solutions. The calculator is available free of charge at www.geotechcarboncalculator.org. The calculator currently addresses foundation solutions using bored piles (drilled shafts), micropiles, diaphragm walls, slurry walls, sheet pile walls, anchors, grouting, soil mixing, stone columns, displacement piles, bored pile walls, vibro compaction, jet grouting, soil nails, soldier pile walls, University PowerPoint presentation sustainable aspects of slurry wall technologies. The group prepared case histories and a presentation that showcases slurry walls applications with sustainable aspects such as lean design, value engineering, and materials and work flow optimization. The presentation highlights the practicality and user-friendliness of the EFFC-DFI carbon calculator, and was prepared as a model for other committee technologies. COMMITTEE CHAIR GARY SEIDER Helical Piles and Tiebacks Committee The Helical Piles and Tiebacks Committee developed an educational PowerPoint presentation on helical pile and tieback solutions. This presentation provides an overview of the history, materials, design, construction and quality control and assurance of helical piles and tiebacks. The committee prepared this presentation as an educational tool for geotechnical university professors as an introduction to the helical products and solutions. The presentation covers basic aspects of the historical develop- ment, design theory and considerations, practical applications, case histories and references for further information. Please visit the committee’s webpage at www.dfi.org to download the presentation and incorporated guidance notes. The committee has plans to present a seminar on cutoff and reinforced slurry walls in infrastructure projects in 2014. After the success of the 2013 seminar that was held adjacent to the Rapid Excavation and Tunneling Conference held in June in Washington, DC, the committee hopes to present the 2014 seminar in conjunction with the North American Tunneling Conference scheduled for June 22-25 in Los Angeles, Calif.
