About the Committee

The Micropile Committee is a joint committee consisting of members of both ADSC and the Deep Foundations Institute (DFI).  Prior to 2019, both ADSC and DFI had their own independent Committees dedicated to Micropiles.  Since both committees had similar goals, and many of the members of the committee were involved in both organizations, the committees joined to allow the collaboration of ideas to better serve the Micropile industry, and ensure the interests of ADSC members are best served.  Each organization has a committee co-chair who is responsible for running regularly scheduled meetings associated with their respective organization.

Mission

Through the use of education, training, seminars, research, specifications, and other means, this committee will work with owners, both private and public, contractors, engineers, and suppliers to increase the use, understanding, quality, and economy of Micropiles systems as defined by this joint committee.

Goals

1. Produce a unified guide specification to incorporate LRFD design and testing methodologies.
2. Produce a Micropile Installation Guide to assist field inspectors in providing quality assurance. Guide to include sections for definitions, materials, installation methods, material QA/QC, and load testing.
3. Produce a Bridging Document as an updated supplement to the 2005 FHWA Micropile Manual. This document will incorporate many topics and represent the state of the practice for micropile design and construction that have become common since the 2005 manual was published.
4. Collaborate with the Anchored Earth Retention Committee to develop an updated Hollow Bar State of the Practice Document that will address hollow bar use in micropiles, soil nails, and prestressed rock and soil anchors.
5. Support current research proposed by the University of Maine to gain further knowledge of the behavior and strength of different manufacturers’ threaded casing joints commonly used in micropiles to resist lateral loads.
6. Search for continued research opportunities to advance the design and construction of micropile systems.
