A new industry-wide Working Group on Working Platforms also held its first meeting, and DFI hosted an exploratory meeting for a potential new group on Project Information Management Systems. Hundreds of DFI committee and DFI’s 18 technical committees and 3 working groups held their annual nd working group members gathered to discuss the many and varied projects aimed at furthering the advancement and understanding of deep foundations. Successes were praised and new challenges proposed to meet the needs of the industry. Please review the summary lists below of ongoing and completed committee projects, and join a committee or working group to become more involved. • Developing a joint study regarding state of practice of ACIP piles in North America, Europe and Australia/New Zealand, to be presented at DFI-EFFC International Conference in Rome, June 2018.
