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 12 technical committees, and deliverables include 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:

All proposals must be submitted through a technical committee for consideration by the Review Committee. The deadline for proposal submissions is December 1. Please contact Mary Ellen Large, DFI technical activities manager, with questions.
