DFI Committee Project Fund

The DFI Board of Trustees established the DFI Committee Project Fund in 2011 to fund DFI Technical Committee projects that advance the state of practice and understanding of deep foundations and produce a usable deliverable. The fund has generated great interest, discussion and activity in the committees. Funding has supported projects proposed by 19 technical committees, and deliverables include laboratory/field testing, installation/demonstration programs, analytical tools, design guides, journal articles, project reports, databases and surveys. All projects involved significant in-kind contributions or joint funding with allied associations, furthering DFI’s industry-wide collaborative efforts.

Proposals are selected based on the following criteria:

  • Benefits to deep foundations industry (broad impact)
  • Innovation
  • Timeliness/relevance/immediacy of impact from results
  • Quality of proposal (clarity, focus)
  • Value of deliverable
  • Probability of achieving goal
  • Cost/benefit and cost sharing (matching funding, in-kind contributions)

Request for Proposals for the 2023 DFI Committee Project Fund are open. The deadline for submission is December 1, 2022. Note that most committees are requesting draft proposals by September 1, 2022.
