DFI Publishes Combined Glossary/Lexicon 

March 12, 2013, Hawthorne N.J.: DFI Europe, a regional chapter of the Deep Foundations Institute (DFI), has published a combined Glossary/Lexicon that merges the DFI Glossary, which included industry definitions mainly used in North America, with a Lexicon of geotechnical terms based on the English language with translations into several European languages. The CEN (European Committee for Standardization) standard terms are included in the Glossary/Lexicon.

According to Tony Butcher, DFI Europe board member and chair of the Reviewing Committee for the Glossary/Lexicon, the goal is to maintain an up-to-date document of equivalent deep foundation terminology used throughout North America and Europe; with plans to expand to other parts of the world.

Industry professionals can review the Glossary/Lexicon and propose additions and changes using an online form at When proposing changes or additions, people are asked to indicate whether a definition or term comes from an ASTM, a CEN Execution or Design Standard (EC7), a DIN Standard or the ICE SPERW, national standards or specification documents, or any other document.
