• Progressing on the state-of-practice white paper on foundation design construction of transmission tower foundations. “Chapter champions” are performing a deep dive into the topics. Related technical committee chairs will review the paper to include their expertise on the topics. • Planning a January or February conference call to define research topics for a 2020 DFI Committee Project Fund proposal. • Enjoying recognition of the committee efforts by ASCE and the Structural Engineering Institute. A new ASCE committee on Electric System Foundations has been established, and its first meeting was held in early December 2019. Many of our DFI committee members are on this new ASCE committee and will be able to provide significant input on foundation design and construction.
