During GEI’s presentation, a number of good questions were generated by the committee. Reponses to these questions were tentatively addressed with the expectations that changes to these conditions may be made as field data is evaluated. The project team also extended an invitation to the committee members for collaboration and technical input as progress continues in this study. The committee strongly encourages members to submit proposals for research funds. The proposals are to be circulated to members for comment and approval, then submitted to DFI for consideration. Proposals must be received by DFI early in December. Take the timing into consideration when submitting a proposal. Ideally proposals should be submitted to the committee by the DFI Annual Conference in Chicago in October. Please do not procrastinate, proposals have been rejected for missing the deadline. During our meeting in October, the committee discussed the preliminary outline for our white paper on recommended QA/QC testing parameters and evaluation. This outline was recently circulated for input and discussion on how the committee should be moving forward with this paper. We will have our next meeting during DFI’s Annual Conference, October 15-18, 2019, in Chicago. Please see the committee meeting schedule on page 34. DFI is hosting an International Deep Mixing Conference, June 15-18, 2020, in Gda ńsk, Poland (see page 45). Hopefully you were able to submit an abstract for this conference and/or will be able to attend. This conference typically shares a tremendous amount of knowledge and research regarding the industry. COMMITTEE CHAIR MIKE KYNETT, P.E. Seepage Control Committee The Seepage Control Committee led the development of a workshop requested by the City of Toronto to address issues related to g roundwa t e r mana g ement dur ing construction of deep basements. The workshop was held at the beautiful Toronto Botanical Gardens. As Toronto continues its rapid development, city officials recognize they must revise their groundwater management policies to address limited storage capacity in their stormwater system. Under the Seepage Control Committee, DFI organized a workshop group to discuss relevant “watertight” foundation technologies, including anchor sealing, secant piles, sheet and pipe piles, diaphragm walls, deep mixing, trenching and jet grouting. Nadir Ansari of Isherwood Associates, Mark Montgomery of Keller Foundations and Dave Wiley, P.Eng., of GFL Infrastructure led the working group efforts and were supported by DFI President Matthew Janes, M.B.A., P.Eng., of Isherwood Associates. DFI members worked for many weeks to create consensus pre- sentations that covered the construction methods, quality assurance and control, and case histories for these techniques. Over half of the attendees were developers and city officials, and the city officials noted that the professionalism and content of the presentations exceeded their expectations. We are grateful to the City of Toronto for reaching out to DFI for foundation technology information.
