Committee is participating member of the GeoCoalition
Code Council.

Developing code change proposals for the 2024 ICC Code
Cycle to upgrade and improve Chapter 18 of the
International Building Code.

In collaboration with ASTM Subcommittee D18.11,
promoting proposed revisions to ASTM D3689 (tension
load testing) and D3966 (lateral load testing).

In collaboration with American Concrete Institute (ACI),
collaborating on new provisions for the design of concrete
deep foundation members now included in ACI 318-19
(structural concrete).

Participating in the development of a proposed new ASCE
standard for foundation design.

Developing an agenda of potential code change proposals
for the upcoming 2024 ICC Code Cycle.

Continuing DFI Committee Project Fund initiative to
update p-y curves for use in practice, specific to foundations
founded in clay or sand to improve design guidance.

Continuing Committee Project Fund initiative to evaluate
cumulative effects of inertial and kinematic loading on
foundations following liquefaction and lateral spreading
to improve design guidance.

Supporting Phase 2 Committee Project Fund initiative to
improve design methodology relating to magnified shear
forces predicted using p-y analyses at the interface of soil
and bedrock, or with other materials of vastly dissimilar
stiffness.

Providing on-site testing contributions to second edition
of EFFC-DFI Guide to Support Fluids for Deep Foundations. The
first edition is available for free on the DFI website.
